slope is -3/2 and the y intercept is 20

Answer:

3x^2 + 13x - 5

Step-by-step explanation:

To find the area, you multiply the length by width. So its is (3x - 1) * (2x + 5)

Then distribute. (3x * 2x) + (3x *5) + (-1 *2x) + (-1 * 5)

So 3x^2 + 15x -2x -5

Final Answer: 3x^2 + 13x - 5

Answer: The answer is Toni can buy 20 tee shirts for 140 dollars

Step-by-step explanation:

First you find out how many times 5 can go into 20

Next you see that 5 can go into 20, 4 times so you take the 35 and multiply 4 and you get 140 so you can buy 20 tee shirts for 140 dollars.

Answer:

x = 5

Answer:

(x + 1)² = 7

Step-by-step explanation:

Given:

-2x = x² - 6

We'll start by rearranging it to solve for zero:

x² + 2x - 6 = 0

The first term is already a perfect square so that's fine.  Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.

Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term.  That value will of course be 1, giving us:

x² + 2x + 1 - 1 - 6 = 0

Now can group our perfect square on the left and our constants on the right:

x² + 2x + 1 - 7= 0

x² + 2x + 1 = 7

(x + 1)² = 7

To check our answer, we can solve for x:

x + 1 = ± √7

x = -1 ± √7

x ≈ 1.65, -3.65

Let's try one of those in the original equation:

-2x = x² - 6

-2(1.65) = 1.65² - 6

- 3.3 = 2.72 - 6

-3.3 = -3.28

Good.  Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

Answer:

119.25

Step-by-step explanation:

36/32 simplified is 9/8.

8 + 7(3+11), I'm assuming it's not x.

8 + 7(14) = 106

(9/8)/106 = 9/8*106 = 954/8 = 119.25

Hope this helps, lmk if the "x" is actually a variable instead of multiplication :)

Answer:

11

Step-by-step explanation:

17+9+11+7 divided by 4

because the mean= sum of the terms divided by the number of terms

the sum= 17+9+11+7=44

the number of terms= 4

44 divided by 4= 11

Answer:

(17+9+11+7) / 4 mean is an average

it is equal to the sum of the elements divided by the number of elements

the sum is 44

the number of elements is 4

the mean is the average= 44/4=11

Answer:

8 in

Step-by-step explanation:

Given data

DIagonal= 10 in

Width= 6 in

`Height=???

We know that the expression that can be used to find the missing dimension is given as

d^2= w^2+h^2

substitute

10^2=6^2+h^2

100= 36+h^2

100-36= h^2

64= h^2

h= √64

h= 8 in

Hence the height is 8 in

Answer:

Step-by-step explanation:

Supplementary angles have a sum of 180 degrees.

a+a-27.2=180

2a-27.2=180

2a=207.2

a=103.6, and since b=a-27.2

b=76.4

So one angle is 103.6 degrees and the other is 76.4 degrees.

Answer:

If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.

To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B

The required steps are in the solution that to use the perpendicular bisector of a segment to draw an isosceles triangle.

An isosceles triangle is defined as a triangle with two sides of equal length.

To use the perpendicular bisector of a segment to draw an isosceles triangle, you can follow these steps:

Draw the segment for which you want to find the perpendicular bisector.

Use a compass to draw a circle with its center at the midpoint of the segment.

With the compass still set to the same radius, draw two arcs that intersect the segment at two points. These points will be the base points of the isosceles triangle.

Draw a line through the midpoint of the segment and the point where the arcs intersect the segment. This line is the perpendicular bisector of the segment.

Use a ruler to draw a line segment connecting the base points of the isosceles triangle.

Use a ruler to draw a line segment connecting the apex of the isosceles triangle (the point where the perpendicular bisector intersects the base) to one of the base points.

At this point, you should have a triangle with two equal sides and a right angle at the apex. This is an isosceles triangle.

Answer:

x = 9

Step-by-step explanation:

Because the angles are vertical angles their measures are congruent so make them equal to each other:

3x -8 = 2x +1     subtract 2x from both sides

-2x       -2x

x -8 = 1            add 8 to both sides

 +8    +8

x = 9
