Answer:
x=21
Step-by-step explanation:
The two angles form a straight line so they add to 180
6x+2+52 = 180
6x+54= 180
Subtract 54 from each side
6x+54-54 = 180-54
6x= 126
Divide by 6
6x/6 =126/6
x = 21
What are the choices, or do you have to give the answer?
Answer:
x = 34
Step-by-step explanation:
Add x+24 to both sides of the equation and simplify.
2 + 8 - x + x + 24 = -24 + x + 24
34 = x
At those two x-intercepts, I know that x=2 and x=-2.
to get this, I know that there are two factors set to 0.
x+2=0 and x-2=0
so, if you multiply (x+2)(x-2)=y
then you will have standard form
x^2+2x-2x-4=y
y=x^2-4
$1722.24 would be the interest earned and $6922.24 is the total balance
