Answer:
$15.35
Step-by-step explanation:
Brush = $10.50
Paint = $22.50
Sales tax = (10.50 + 22.50) x 0.05 = $1.65
Add up all the money Jen needs to pay = 10.50 + 22.50 + 1.65 = $34.65
Jen paid with a $50 bill so subtract 34.65 from 50 to get $15.35
Y + 2 = -2(x - 5)
Simplify.
y + 2 = -2x + 10
Subtract 2 from both sides.
y = -2x + 10 - 2
Simplify.
y = -2x + 8 → Slope-intercept form
Our answer is the second option : y=-2x+8
~Hope I helped!~
X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
If the 2 is an exponent, it should be marked as such.
“3x2” means 3x⋅2
“3x^2” means 3x²
3x²+8x = 0
Discriminant = 8²-4(3)(0) = 64
