Beginning with the equation x= -90, write the new equation produced by dividing both sides by 10

kobusy [5.1K]

Answer:

x/10 = -9

Step-by-step explanation:

You are given the equation: x = -90

You are asked to divide 10 from both sides. Simplify:

(x)/10 = (-90)/10

x/10 = -90/10

x/10 = -9

x/10 = -9 is your answer.

Find the area of the polygon

larisa [96]

Answer:

$687.5 \: {ft}^{2}$

Step-by-step explanation:

Area of polygon = Area of square + Area of triangle

$= {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2}$

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the

Pani-rosa [81]

Answer:

10x + 5y = 11

Step-by-step explanation:

I usually find it in slope intercept then convert, it's easier for me.

First you find slope using delta y over delta x giving you -2/5.

so you have y=-2/5x + b

To find b plug in a point and solve down

1 = -2/5(3) +b

1+6/5 = b

b = 11/5

y=-2/5x + 11/5

Then you convert it to Ax+by=C form,

multiply by 5

5y = -10x + 11

move x

10x +5y = 11
