Answer:
z^2 +7z -8 = 0
Step-by-step explanation:
Let z = 3x+2. Then we can substitute z wherever we see 3x+2.
z^2 +7z -8 = 0 . . . . equivalent quadratic
__
This is easily factored to ...
(z -1)(z +8) = 0
So, the original quadratic has solutions ...
(3x +2) -1 = 0
x = -1/3
and
(3x +2) +8 = 0
x = -10/3
The answer is B

Answer:
to find slope you have to set the equation to y=
2x-4y=10
+4y +4y
2x=10+4y
-10 -10
2x-10=4y
/4 /4
1/2x-(10/4)=y
slope equals 1/2
In this question , there are several information's that has been provided and are of immense importance. Cost of a new CD player in North Carolina cost $225. The sales tax applied is 4.75%. The amount of savings during tax free period has to be calculated.
Then
The amount of money that the customer will
save during tax free period = 225 * (4.75/100)
= 225 * 0.0475
= 10.687
So the person will save $10.687 or you can take it as $10.69 during the tax free period.
