Answer:
= -3 (x-y)
Step-by-step explanation:
-5x - 4y + 2x + 7y
Collect the like terms by calculating the sum or difference of their coefficients
(-5+2)x
-3x
(-4+7)y
3y
-3x + 3y
Factor out -3 from the expression
-3 (x-y)
Answer:
$7.50
Step-by-step explanation:
3/4 of the original price
Original price: $10
So we need 3/4 of $10
10 ÷ 4 = 2.5
2.5(3) = 7.5
3/4 of $10 = 7.5, so the price is now $7.50
Answer:
y = -5x - 23
Step-by-step explanation:
Write it in point - slope form:
y - 7 = -5(x + 6)
rearrange:
y - 7 = -5x - 30
y = -5x - 23
(9/6) = (15/?)
9? = 90
? = 10
The absolute value is the number disregarding (ignoring) the positive or negative sign. So the absolute value of -282 is l 282 l :)
