3 + 4x = 2y - 9
2y = 4x + 3 + 9
2y = 4x + 12
y = 2x + 6
if it's parallel, than if y = ax + b, a = 2 and you need to find b
(4, -4)
x = 4
y = -4
-4 = 2*4 + b
-4 = 8 + b
b = -12
so an equation is:
y = 2x - 12
Answer:
$87.90
Step-by-step explanation:
Let the amount of money Hashim had be $Y. As such, if he gives his mother $28, he would have $Y - $28 left.
If he had $15.20 less than his sister and his sister had $75.10, then we can say that what he had left $Y - $28 is equivalent to the difference between $75.10 and $15.20.
This is
$Y - $28 = $75.10 - $15.20
Y = $28 + $75.10 - $15.20
= $87.90
Answer: 20y - 7.5
(3 - 8y) * (-2.5)
(3 * -2.5) + (-8y * -2.5)
-7.5 + 20y
20y - 7.5
