Answer:

m = -3/4
y-intercept = 399
slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

3x + 4y = 1596

4y = -3x + 1596 . . . . subtract 3x

y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.

A pipe is to be cut up such that the second piece is 3 inches shorter than the first and the third piece is

Lera25 [3.4K]

Answer:

$F = 27\frac{2}{3}$

$S = 24\frac{2}{3}$

$T = 31\frac{2}{3}$

Step-by-step explanation:

Represent the first piece with F, the second with S and the third with T.

So:

$S = F - 3$

$T =4+ F$

$S + T + F = 84$

Required

Find the length of each piece

Substitute $S = F - 3$ and $T =4+ F$ in $S + T + F = 84$

$F - 3 + 4 + F + F = 84$

Collect like terms

$3F = 84 + 3 - 4$

$3F = 83$

Divide through by 3

$F = \frac{83}{3}$

$F = 27\frac{2}{3}$

Substitute $F = 27\frac{2}{3}$ in $S = F - 3$ and $T =4+ F$

$S = F - 3$

$S = 27\frac{2}{3} - 3$

$S = 24\frac{2}{3}$

$T =4+ F$

$T = 4 + 27\frac{2}{3}$

$T = 31\frac{2}{3}$
