2
Step-by-step explanation:
Rearrange to same form:
2y = -5x + 10
y = -5/2x + 10
ay = -5x + 4
Parallel lines have no intersection and solution, thus a = 2
.00045-2.5×10^-5
= 4.5 x10^-3 - 2.5 x10^-5
= 4.25 x10^-4
She can pour her orange juice into five different containers that hold 3/4 of a gallon.
1. You can convert 3/4 to .75.
2. Then, divide 3.75 by .75 to get an answer of 5, which means 5 containers.
When you solve an inequality, you should always be extra careful to check that you don't multiply it by a negative number - because if you do, then you have to change the sign!
So here, the mistake is in this step:
−9x≥ −36
x ≥ 1.
you should change the sign to ≥
x≤1!
