Last season two running backs on the Steelers football team rushed or a combined total of 1550 yards. One rushed 9 times as many
Nikolay [14]
To answer this question, you will represent the amount of yards rushed by each running back.

x - Running back #1
9x - Running back #2

The combined yards was 1550, so put these together in an addition equation with a total of 1550.  Solve for x.

x + 9x = 1550
10x = 1550
x = 155

Running back #1 rushed 155 yards, and running back #2 rushed for 1395 yards.

Factor completely. y2 - xy - 56x2
aliina [53]
For this case we have the following expression:
 y2 - xy - 56x2
 Rewriting we have the factored expression, which is given by:
 (7x + y) (y-8x)
 Checking we have:
 7xy - 56x ^ 2 + y ^ 2 - 8xy
 y ^ 2 - xy - 56x ^ 2 (OK)
 Answer:
 
The factored expression is given by:
 
y2 - xy - 56x2 = (7x + y) (y-8x)

Which of the following lines is perpendicular to the line 8x + 6y = 12 and passes through the point (-12,-2)?​
VLD [36.1K]

Answer:

y = 3/4x + 7

Step-by-step explanation:

8x + 6y = 12

6y = -8x + 12

y = -4/3x + 2

Perpendicular slope: 3/4

y - y1 = m(x - x1)

y + 2 = 3/4(x + 12)

y + 2 = 3/4x + 9

y = 3/4x + 7
