Answer:

y = 8/7x -18/7

Step-by-step explanation:

8x-7y=18

Subtract 8x from each side

8x-8x-7y=-8x+18

-7y = -8x+18

Divide each side by -7

-7y/-7 = ( -8x+18)/-7

y = 8/7x -18/7

A triangle has sides with lengths of 6 yards, 8 yards, and 10 yards. Is it a right triangle?

yaroslaw [1]

Answer:

Step-by-step explanation:

so, by the Pythagorean theorem

If it is a right triangle:

a^2 + b^2 = c^2

so,

6^2 = 36

8^2 = 64

10^2 = 100

okay, now we plug these into the equation

36 + 64 = 100

so yes, it is a right triangle.

Hope this helped!

Find the value of y so that line is passing through two points

Alenkinab [10]

Slope of a line passing through two given points
= (y2-y1)/(x2-x1)

For m=3, and substituting coordinates,
3=(1-y)/(4-1)
solve for y
1-y=3*3=9
y=1-9=-8

Answer: y=-8

Answer:

$72 in^2$

Step-by-step explanation:

First, find the area of the bigger shape. Then, separately, find the smaller shape's area. Subtract the smaller one by the big boi, and you'll get the area of the shaded area. You can count the little squares too.

12*8=96

4*6=24

96-24=72

No.
