99 POINTS PLS HELP Write the equation in slope-intercept form. 4x + 3y = 15
Kisachek [45]

To write in slope intercept form solve the equation for y:

4x + 3y =15

Subtract 4x from both sides:

3y = -4x +15

Now get Y by itself by divide all terms by 3:

y = -4/3x + 5

31-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece and the third piece
pychu [463]

"31-inch piece of steel is cut into three pieces"

Call the pieces a,b,c

a + b + c = 31

"second piece is twice as long as the first piece"

b = 2a

"third piece is one inch more than seven times the length of the first piece"

c = 1 + 7a

Ok, we have our equations, let's substitute the second and third into the first.

a + 2a + 1 + 7a = 31

10a + 1 = 31

10a = 30

a = 30/10 = 3

b = 2a = 6

c = 1 + 7a = 22

Check: 3 + 6 + 22 = 31, good

Answer: 3 inches, 6 inches, 22 inches
