Answer: the 5 in the parentheses on the second line should be negative. Also, where did the 23 go?? That's a mistake too.
Step-by-step explanation: 3 - 8 = -5 so
23(2 - 4) + 5(3 - 8)
23(-2) + 5(-5)
(-46) + (-25)
-71
(at least, I think so unless there was a mistake in the equation)
Were doing the same test its a.
Y=3x²-6x+4
to put in vertex form, make a square by adding (half of b)²
but first, we have to make a=1 by take out the 3:
y=3(x²-2x)+4
b=-2, half of b=-1, (-1)²=1, so add 1, then subtract 1 inside the parenthesis:
y=3(x²-2x+1-1)+4
make the square: y=3[(x-1)²-1]+4
simplify: y=3(x-1)²-3+4=3(x-1)²+1
so the answer is A.
Answer:
$552.50
Step-by-step explanation:
To find how much she will make, find 6.5% of 8500
8500(0.065)
= 552.5
So, she will make $552.50
