The best choice is A)
when you add a zero, it does not count on a decimal, so,
1.9, 1.90, 1.900.
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.
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)
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
