A horizontal line is in the form

y =

This means the x component changes and the y component stays the same

( -7, 10)

The line is in the form

y = 10

x can be any value

The slope is zero since it is horizontal

The point ( 3,10) is on the line

The equation of the line is y = 10

The y intercept is 10 not -7

To answer this question, we need to factor each of the polynomials as follows:

First Polynomial

To factor it, we need to find two numbers:

a*b = 3

a + b = 4

These numbers are:

a = 3

b = 1

Therefore, we have:

Find the scale factor of the two prisms, the ratio of their surface areas, and the ratio of theirvolumes. List the larger values first.6 cm8 cm9 cm10 cm12 cm15 cmScale FactorSurface AreasVolumesBlank 1:Blank 2:Blank 3:Blank 4:Blank 5:Blank 6:

Answers

We will operate as follows:

*Scale factor:

We determine the scale factor using two respective sides, that is:

[tex]9x=6\Rightarrow x=\frac{6}{9}\Rightarrow x=\frac{2}{3}[/tex]

So, the scale factor is 2 : 3.

*Surface area:

We determine the surface are of each prism:

[tex]S_{A1}=(9\cdot12)+2(\frac{15\cdot9}{2})+(12\cdot\sqrt[]{15^2+9^2})+(15\cdot12)\Rightarrow S_{A1}=(108)+(135)+(36\sqrt[]{34})+(180)[/tex][tex]\Rightarrow S_{A1}=423+36\sqrt[]{34}\Rightarrow S_{A1}=632.9142682\ldots[/tex][tex]S_{A2}=(6\cdot8)+2(\frac{6\cdot10}{2})+(10\cdot8)+(8\cdot\sqrt[]{6^2+10^2})\Rightarrow S_{A2}=(48)+(60)+(80)+(16\sqrt[]{34})[/tex][tex]\Rightarrow S_{A2}=188+16\sqrt[]{34}\Rightarrow S_{A2}=281.2952303\ldots[/tex]

Now:

[tex](423+36\sqrt[]{34})x=188+16\sqrt[]{34}\Rightarrow x=\frac{188+16\sqrt[]{34}}{423+36\sqrt[]{34}}\Rightarrow x=\frac{4}{9}[/tex]

So, the ratio of the surface areas is 4 : 9.

*Volume:

We determine the volume of each prism and proceed as before:

[tex]V_1=\frac{9\cdot15\cdot12}{2}\Rightarrow V_1=810[/tex][tex]V_2=\frac{6\cdot10\cdot8}{2}\Rightarrow V_2=240[/tex]

Now:

[tex]810x=240\Rightarrow x=\frac{240}{810}\Rightarrow x=\frac{8}{27}[/tex]

So, the ratio for the volumes is 8 : 27.

Answers

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define complementary angles

When the sum of two angles is 90°, then the angles are known as complementary angles.

STEP 2: Write the pairs of the angles formed

[tex]\begin{gathered} (2x-20)\degree \\ (4x-10)\degree \end{gathered}[/tex]

STEP 3: find the value of x

Following the definition in step 1, this goes that;

[tex]\begin{gathered} (2x-20)+(4x-10)=90\degree \\ 2x-20+4x-10=90\degree \\ 6x-30=90 \\ 6x=90+30 \\ 6x=120 \\ x=\frac{120}{6}=20 \end{gathered}[/tex]

STEP 4: Find the two pair of angles

[tex]\begin{gathered} (2x-20)=2(20)-20=40-20=20\degree \\ 4x-10=4(20)-10=80-10=70\degree \end{gathered}[/tex]

The sequence below shows the number of trees that a nursery plants each year.2, 8, 32, 128 ...Let an represent the current term in the sequence and an-1 represent the previous term in thesequence. Which formula could be used to determine the number of trees the nursery will plantin year n?

Answers

According to the given sequence, the formula that could be used to determine the number of trees the nursery will plant in year n is [tex]a_{n}= 4a_{n-1}[/tex]. Thus, option (A) is correct.

The given sequence of the number of trees that a nursery plants each year is -

2, 8, 32, 128, .....

[tex]a_{n}[/tex] = The current term in the sequence

[tex]a_{n-1}[/tex] = The previous term in the sequence

We have to find out the formula that could be used to determine the number of trees that the nursery will plant in the year n.

From the sequence we can see that -

8 = 2*4

32 = 8*4

128 = 32*4

So, this can be said that the current term in the sequence ([tex]a_{n}[/tex]) is 4 times the previous term in the sequence ([tex]a_{n-1}[/tex]).

=> [tex]a_{n}= 4a_{n-1}[/tex]

Thus, according to the given sequence, the formula that could be used to determine the number of trees the nursery will plant in year n is

[tex]a_{n}= 4a_{n-1}[/tex]

Thus, option (A) is correct.

Solve the system of linear equations using the graphing method. Use “no solution” and “infinitely many” when appropriate.

Answers

Given the system of equations:

[tex]\begin{gathered} y=\frac{1}{2}x+2 \\ \\ y=\frac{1}{2}x+1 \end{gathered}[/tex]

Let's solve the system using graphing method.

Let's plot both equations on a graph. The point where both lines meet.

• Equation 1:

Let's plot using 3 points.

Substitute random values of x and solve for y.

We have:

[tex]\begin{gathered} x=-4;\text{ y = }\frac{1}{2}(-4)+2=-2+2=0 \\ \\ x=0;y=\frac{1}{2}(0)+2=0+2=2 \\ \\ x=4;y=\frac{1}{2}(4)+2=2+2=4 \end{gathered}[/tex]

For equation 1, we have the points:

(x, y) ==> (-4, 0), (0, 2), (4, 4)

Plot the points and connect the points with a straight line.

• Equation 2:

Let's create 3 points:

[tex]\begin{gathered} x=-2;y=\frac{1}{2}(-2)+1=-1+1=0 \\ \\ x=0;y=\frac{1}{2}(0)+1=0+1=1 \\ \\ x=2;y=\frac{1}{2}(2)+1=1+1=2 \end{gathered}[/tex]

FOr equation 2, we have the points:

(x, y) ==> (-2, 0), (0, 1), (2, 2)

Now, plot the points and connect using a straight line.

We have the graph of both equations below:

From the graph, we can see that both lines do not meet at any point.

They are parallel lines,

Since they will not meet at any point, there is NO SOLUTION.

Step-by-step explanation:

f(x) = 8x - 1

==> replace "f(x)" with y

y = 8x - 1

==> inter exchange x and y

x = 8y - 1

==> solve for y now, first step would be to add 1 to both sides

x + 1 = 8y

==> divide both sides by 8

(x+1)/8 = y

==> replace y with f^-1(x)

f^-1(x)=(x+1)/8y

Where:

RM = 5x + 9

MT = 8x - 6

RT = 198

Replacing the data:

5x + 9 + 8x - 6 = 198

Add like terms:

(5x + 8x) + (9 - 6) = 198

13x + 3 = 198

Solve for x:

Subtract 3 from both sides:

13x = 195

Divide both sides by 13:

Distributive Property equation8x4=(_x_)+(_x_)

Answers

Answer:

8 x 4 = (8 x 2) + (8 x 2)

Explanation:

The distributive property says that:

a x (b + c) = (a x b) + (a x c)

Then, we can write 4 as (2 + 2), so:

8 x 4 = 8 x ( 2 + 2)

Now, we can apply the distributive property:

8 x 4 = (8 x 2) + (8 x 2)

Therefore, the answer is:

8 x 4 = (8 x 2) + (8 x 2)

Given triangle ABC below, if angle B=(x-60)^ and angle C=(x- 45)^ find the measure of angle x

Answers

Given:

m∠B = (x - 60)°

m∠C = (x - 45)°

Opposite angle = x°

Let's find the measure of angle x.

To find the measure of angle x, apply the Exterior Angle Theorem which states that the exterior angle of a triangle is equal to the sum of the two opposite angles.

Thus, we have:

∠B + ∠C = x

(x - 60) + (x - 45) = x

Solve for x.

• Remove the parentheses and combine like terms:

x - 60 + x - 45 = x

x + x - 60 - 45 = x

2x - 105 = x

• Move all terms containing x to the left, then move 105 to the right

2x - x = 105

x = 105°

Therefore, the measure of angle x is 105°

ANSWER:

x = 105°
