The function, fx) = x^2 - 4x + 3, has y-values that increase when x<2. TrueFalse

Answers

Let's begin by listing out the information given to us:

[tex]\begin{gathered} f(x)=x^2-4x+3 \\ f(x)=y \\ \Rightarrow y=x^2-4x+3 \\ y=x^2-4x+3 \end{gathered}[/tex]

We will proceed to choose values for x (values of x lesser than 2); x = 1, 0, -1

[tex]\begin{gathered} y=x^2-4x+3 \\ x=1 \\ y=1^2-4(1)+3=1-4+3=4-4=0 \\ y=0 \\ (x,y)=(1,0) \\ \\ x=0 \\ y=0^2-4(0)+3=0-0+3=3 \\ y=3 \\ (x,y)=(0,3) \\ \\ x=-1 \\ y=(-1^2)-4(-1)+3=1+4+3=8 \\ y=8 \\ (x,y)=(-1,8) \end{gathered}[/tex]

Find the solution of the system of equations.5 +2g = 185x-Y=36

Answers

Ok we have the following system of equations:

[tex]\begin{gathered} 5x+2y=18 \\ 5x-y=36 \end{gathered}[/tex]

So the first thing to do is take one of the equations above and clear either x or y. I'm going to pick the second equation and clear y:

[tex]\begin{gathered} 5x-y=36 \\ 5x=36+y \\ 5x-36=y \\ y=5x-36 \end{gathered}[/tex]

Now we substitute this result in the first equation:

[tex]\begin{gathered} 5x+2y=5x+2\cdot(5x-36)=18 \\ 5x+10x-72=18 \\ 15x=18+72=90 \\ x=\frac{90}{15}=6 \end{gathered}[/tex]

Now that we know x we take the result of clearing y from the second equation and find its value:

[tex]\begin{gathered} y=5x-36 \\ y=5\cdot6-36=30-36 \\ y=-6 \end{gathered}[/tex]

So in the end x=6 and y=-6.

Answers

Activity 1:

We are given two triangles. The two side lengths of one triangle are known but of the other are not. Our task is to choose the value of x and y that will make the triangles congruent.

Now, the side lengths that are congruent are with 31 in the rightmost triangle and 7x -4 in the left-most triangle; therefore, equating them gives

[tex]7x-4=31[/tex]

Similarly, side length 24 must equal 4y+8; therefore,

[tex]4y+8=24[/tex]

Now we have to choose the values of x and y that will make both equations true.

Let us solve for x in the first equation by first adding 4 to both sides. Doing this gives

[tex]7x=35[/tex]

Finally, dividing both sides by 7 gives

[tex]x=5.[/tex]

Activity 2:

Now, for the value of y.

To solve for y, we first subtract 8 from both sides to get

[tex]4y=16[/tex]

Finally, dividing both sides by 4 gives

Hence, to conclude x = 5 and y = 4.

Answers

y = -x/3 +11 is the line perpendicular to y = 3x +7 and passes through the point (-6,9)

What is a slope-intercept form?

It gives the graph of a straight line and it is represented in the form

y= mx +c. It is one of the form used to calculate the equation of a straight line. We have to calculate the slope of the line from the equation. The slope calculated can be used in the slope-intercept form. It is the most popular form of a straight line.

We need to find the perpendicular slope to the line y = 3x +7.

The slope of a line perpendicular to m is -1/m

Here, from the equation y=3x+7, m=3

So,-1/m = -1/3

The slope-intercept form is,

y-y1=m(x-x1)

y - 9 = -1/3 * (x+6)

Now, simplify the above equation

y-9= -x/3 +6/3

By adding 9 on both sides, we get

y= -x/3 +11

y = -x/3 +11 is the line perpendicular to y = 3x +7 and passes through the point (-6,9)

What is a multiple root of a polynomial and how do you find it?

Answers

The Solution:

The given polynomial is

[tex]P(x)=2x^4-4x^3-16x^2[/tex]

A root of the polynomial P(x) is the value of x for which the polynomial P(x) is equal to zero.

That is, any value of x that makes P(x) = 0, is a root of P(x).

The Multiplicity of a Root: This is the number of times a particular root appears as a root in a polynomial.

To find the root of a polynomial, say P(x), you have to equate P(x) to zero, and then solve for the value of x.

So, we shall follow the above procedures to find the root(s) of P(x), and thereafter determine if there are multiple roots.

[tex]\begin{gathered} P(x)=2x^4-4x^3-16x^2=0 \\ \text{Factoring out 2x}^2,\text{ we have} \\ 2x^2(x^2-2x-8)=0 \end{gathered}[/tex]

This means that:

[tex]\begin{gathered} x^2-2x-8=0 \\ or \\ 2x^2=0 \end{gathered}[/tex]

Solving quadratic equations above by Tthe Factorization Method, we get

[tex]\begin{gathered} x^2-2x-8=0 \\ x^2-4x+2x-8=0 \\ x(x-4)+2(x-4)=0 \\ (x-4)(x+2)=0 \end{gathered}[/tex]

So,

[tex]\begin{gathered} P(x)=2x^2(x-4)(x+2)=0 \\ \text{This means} \\ 2x^2=0\text{ }\Rightarrow x=0 \\ x-4=0\text{ }\Rightarrow x=4 \\ x+2=0\text{ }\Rightarrow x=-2 \\ So,\text{ the roots of P(x) are 0, -2, and 4} \end{gathered}[/tex]

Looking at the roots of P(x) above, there is no root that appears more than once, hence, the multiplicity of each of the roots is one.

4) A cannonball is shot out of a cannon at a 459angle with an approximatecannon from which the ball was fired sits on the edge of a cliff, and its he20 meters. The equations given below represent the cannonball's heighand its horizontal distance (x) from the face of the cliff, (E)seconds afterHow many seconds after the ball was fired does its verticat height abovehorizontal distance from the cliff?

Answers

Let t be the amunt of seconds that have passed when the height of the cannonball above the ground is the same as its horizontal fistance from the cliff.

Since the height of the cannonball above the ground is represented using the variable y and the horizontal distance from the cliff is represented using the variable x, then, the condition that the height equals the horizontal distance can be expressed as:

[tex]y=x[/tex]

Replace the expressions for y and x in terms of t into the equation:

[tex]-5t^2+2t+20=2t[/tex]

We obtained a quadratic equation on the variable t.

Notice that the term 2t appears in both members of the equation. Then, it can be cancelled out:

[tex]-5t^2+20=0[/tex]

Solve for t²:

[tex]\begin{gathered} \Rightarrow-5t^2=-20_{} \\ \Rightarrow t^2=\frac{-20}{-5} \\ \Rightarrow t^2=4 \end{gathered}[/tex]

Take the square root to solve for t:

[tex]\begin{gathered} \Rightarrow t=\pm\sqrt[]{4} \\ =\pm2 \end{gathered}[/tex]

Since t must be greater or equal to 0, then the negative solution should be discarded.

Therefore, the vertical height of the cannonball equals its horizontal distance from the cliff 2 seconds after the ball is fired.

QuestionsWhat is the equation of the line?y = 2x - 4y = 1/2x + 2y = 2x + 2y = 1/2x-4

Answers

We have the graph of the equation, and we want to know the equation of the line.

We remember that we need to parts: the slope and the y-intercept. On the graph, we see that when x=0, the graph passes through the point 2, and thus the y-intercept is 2.

[tex]b=2[/tex]

Lastly, we will find the slope. For doing so, we will find two values of the line. In this case, we saw that the y-intercept is 2, so a point is (0,2).

Other point is (-4,0), as the x-intercept is -4.

For finding the slope, we remember the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-0}{0-(-4)}=\frac{2}{4}=\frac{1}{2}[/tex]

And thus, the slope is 1/2.

This means that the line equation will be:

Answers

Answer:

Form:

[tex]\boxed{(x-9)^2=11}[/tex]

Solution:

[tex]x=12.32,5.68[/tex]

Explanation:

Step 1. The expression we have is:

[tex]x^2-18x+70=0[/tex]

And we are required to find the appropriate form after completing the square, and then the solution or solutions to the equation.

Step 2. Compare the given equation with the general quadratic equation:

[tex]ax^2+bx+c=0[/tex]

Our values for a, b, and c are:

[tex]\begin{gathered} a=1 \\ b=-18 \\ c=70 \end{gathered}[/tex]

Step 3. Using the value of b, find the following expression:

[tex](\frac{b}{2})^2[/tex]

The result is:

[tex](-\frac{18}{2})^2\longrightarrow(-9)^2[/tex]

Step 4. Take the original equation

[tex]x^2-18x+70=0[/tex]

Move the +70 as a -70 to the right-hand side:

[tex]x^2-18x=-70[/tex]

And now add to both sides the expression found in step 3 for (b/2)^2:

[tex]x^2-18x+(-9)^2=-70+(-9)^2[/tex]

Step 5. Factor the left-hand side of the equation as a perfect square binominal:

[tex]\begin{gathered} P\operatorname{erf}ect\text{ square binomial formula:} \\ (a\pm b)^2=a^2\pm2ab+b^2 \end{gathered}[/tex]

Applying this to our expression:

[tex](x-9)^2=-70+(-9)^2[/tex]

Step 6. Solve the operations on the right-hand side:

[tex]\begin{gathered} (x-9)^2=-70+81 \\ \downarrow\downarrow \\ \boxed{\mleft(x-9\mright)^2=11} \end{gathered}[/tex]

The form is the equation is:

[tex]\boxed{(x-9)^2=11}[/tex]

Step 7. To find the value or values of x, solve for x in the previous equation:

[tex]\begin{gathered} (x-9)^2=11 \\ \downarrow\downarrow \\ x-9^{}=\pm\sqrt[]{11} \\ \downarrow\downarrow \\ x^{}=\pm\sqrt[]{11}+9 \end{gathered}[/tex]

Step 8. To find the two solutions we use the '+' and '-' signs separately:

[tex]\begin{gathered} x^{}=\sqrt[]{11}+9\longrightarrow x=3.3166+9=12.3166 \\ x^{}=-\sqrt[]{11}+9\longrightarrow x=-3.3166+9=5.6834 \end{gathered}[/tex]

Rounding these values for x to the nearest hundredth (2 decimal places):

[tex]\begin{gathered} x=12.32 \\ x=5.68 \end{gathered}[/tex]

Answer:

Form:

[tex]\boxed{(x-9)^2=11}[/tex]

Answers

The rate of change of a linear functions is given by:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where (x1,y1) and (x2,y2) are points through the graph.

Function 1.

From the table we have that the functions passes through the points (-11,8) and (-7,13), pluggin the values in the formula above we have:

[tex]\begin{gathered} m=\frac{13-8}{-7-(-11)} \\ m=\frac{5}{11-7} \\ m=\frac{5}{4} \end{gathered}[/tex]

Therefore the rate of change of functions 1 is 5/4

Function 2.

From the graph we notice that the functions passes through the points (-3,-4) and (1,-1), hence:

[tex]\begin{gathered} m=\frac{-1-(-4)}{1-(-3)} \\ m=\frac{-1+4}{1+3} \\ m=\frac{3}{4} \end{gathered}[/tex]

Therefore the rate of change of function 2 is 3/4.

Comparing both rates of change we conclude that Function 1 has the greater change of rate.
