A line is drawn over this rectangle . Is the line a line of symmetry?

First, let's find the slope of the line that passes through the points (-4,3) and (6,2):

Now we can use the first point to get the equation of the line:

therefore, the equation of the line is y=-1/10x+13/5

We are given the following equation:

Where are asked to find the value of "u". To do that we need first to solve for "u", first by adding 4 on both sides:

Now, we will divide by 2 on both sides:

Therefore, the value of "u" is 5

Given : b(x) = | x + 4 |

So, to find b(-10) , substitute with x = -10 at the function b(x)

So, b(-10) = | -10 + 4 | = | -6 | = 6

The given equations are

y = x^2 + 2x + 7

y = x + 7

We would substitute y = x + 7 into the first equation. It becomes

x + 7 = x^2 + 2x + 7

Collecting like terms, it becomes

x^2 + 2x - x + 7 - 7 = 0

x^2 + x = 0

By factorising x, it becomes

x(x + 1) = 0

Thus,

x = 0 or x + 1 = 0

x = 0 or x = - 1

Substituting x = 0 into y = x + 7, it becomes

y = 0 + 7

y = 7

Thus, one solution set is (0, 7)

Substituting x = - 1 into y = x + 7, it becomes

y = - 1 + 7

y = 6

Thus, another solution set is (- 1, 6)

Therefore, the solution sets are

{(0, 7), (- 1, 6)}

Option A is correct

Part 1

we have

2(3m+7)

For m=1 ------> 2(3(1)+7)=2(10)=20

For m=2-----> 2(3(2)+7)=2(13)=26

we have

6m+14

For m=1 -----> 6(1)+14=20

For m=2----> 6(2)+14=26

Remember that

2(3m+7) is the same that 6m+14

The vertex Y is triangle WXY is (7, -8)

The triangle will translate by the rule (x + 3, y - 4)

That means it will be moved right 3 units and down 4 units

So we will add the x-coordinate of point Y by 3 and subtract its y-coordinate by 4 to get its image Y'

The image of point Y is

Y' = (7 + 3, -8 - 4)

Y' = (10, -12)

The correct answer is C

To find the zeros of multiplicity one, multiplicity 2, multiplicity 3.

Now,

The zeros of multiplicity 1 are,

The zeros of multiplicity 2 are,

There are no zeros of multiplicity three since the polynomial has no factor to the power 3.

From the image above,

measured angle 2 is 80degrees because the corresponding angles are equal.

Also meansured angle 1 + measured angle 2 is 180 degrees;

because the sum of angles on a straight line is 180 degrees

So we have:

Therefore the percent of the people surveyed that liked red cars is 4%.

Step 1:

Let the height below sea level before she descends = h feet

The length she descended after 10 minutes = 21.4 feet

The height of the submarine after descended below the sea level = 90.6 feet

Step 2:

Height of the submarine before descended below the sea level

x = 90.6 - 21.4

x = 69.2 feet

Final answer

69.2 feet

The tangential speed of a disk is  94.23.

Given:

radius (r) = 15meters

time t = 7 sec

tangential speed = 2[tex]\pi[/tex]r/t

                           = 2x 3.141x 15/7

                           = 94.23

Tangential speed is the linear component of its velocity as it moves in a circle. If an object moves along a circular path at a distance r from the centre of the circle, the velocity of the object is tangent to the circle at some point.

In mathematics, a tangent is a line that touches a curve at one point. A quantity is tangent to another if it touches the other quantity once and then moves in the other direction.

Therefore, the tangential speed is a measure of the speed at any point where the tangent curves in this circular motion. Tangential velocity is useful for circular motion because it allows angular motion to be transformed into linear motion.

Bob and dale served a total of 83 orders Monday at the school cafeteria. rita served 9 fewer orders than bob. Dale served 2 times as many orders as bob. how many orders did they each serve​

Solution

We can find the number of orders for Rita like this:

And for Dale we have this:

How much did she spend?

She had 80 dollars, and after buying them she had 16 dollars. Then she spent

80 - 16 = 64

she spent $64 on 8 books.

How much did each book cost?

Since 8 books cost $64, each one should cost:

64 ÷ 8 = 8

each one cost $8.

Since a whole revolution has 360º, when we have an angle bigger than 360º the angles start to repeat.

We can subtract 360º to the given angle to find the coterminal angle. In this case:

And from an reference angle of 0º, this is exactly a half revolution. Thus, the angle is in the x axis, and it's coterminal angle is 180º

Because there are 9 rows of tomato plants and each row has 8 tomatos, you would be doing 9x8 and get your answer of 72. Hope this makes sense!

Answer

The answer is 17.

Explanation

The absolute value of any number is taking the positive part of any number. For example, the absolute value of -2 = | -2 | = 2, the absolute value of -99 = | -99 | = 99.

So, the absolute value of -17 = | -17 | = 17.

=====================

Answer:

[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}\phantom{bbbb}y=x^2+9\\x+y=11\end{cases}[/tex]

To solve by the method of substitution, rearrange the second equation to make y the subject:

[tex]\implies y=11-x[/tex]

Substitute the found expression for y into the first equation and rearrange so that the equation equals zero:

[tex]\begin{aligned}y=11-x \implies 11-x&=x^2+9\\x^2+9&=11-x\\x^2+9+x&=11\\x^2+x-2&=0\end{aligned}[/tex]

Factor the quadratic:

[tex]\begin{aligned}x^2+x-2&=0\\x^2+2x-x-2&=0\\x(x+2)-1(x+2)&=0\\(x-1)(x+2)&=0\end{aligned}[/tex]

Apply the zero-product property and solve for x:

[tex]\implies x-1=0 \implies x=1[/tex]

[tex]\implies x+2=0 \implies x=-2[/tex]

Substitute the found values of x into the second equation and solve for y:

[tex]\begin{aligned}x=1 \implies 1+y&=11\\y&=11-1\\y&=10\end{aligned}[/tex]

[tex]\begin{aligned}x=-2 \implies -2+y&=11\\y&=11+2\\y&=13\end{aligned}[/tex]

Therefore, the solutions are:

[tex](x,y)=\left(\; \boxed{-2,13} \; \right)\quad \textsf{(smaller $x$-value)}[/tex]

[tex](x,y)=\left(\; \boxed{1,10} \; \right)\quad \textsf{(larger $x$-value)}[/tex]
