Answer:
P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10
= 2(16) - 5(-8) + (-2) - 10
= 32+40-2-10
= 60
P(1) = 2(1^4) - 4(1^3) + (1) - 10
= 2 - 4 + 1 - 10
= -11
P(2). = 2(2^4) - 5(2^3) + (2) - 10
= 2(16) - 5(8) + 2 - 20
= 32-40+2-10
= -20
You would answer this question using simultaneous equations, so if m is movies and v is video games, then:
9m + 7v = 65
3m + 5v = 37
9m + 7v = 65
9m + 15v = 111
(minus)
-8v = -46
÷ -8
v = $5.75
Then you can substitute the value of V in to find the value of m, so:
3m + (5 × 5.75) = 37
3m + 28.75 = 37
- 28.75
3m = 8.25
÷ 3
m = 2.75
So you get the answers as Video Games are $5.75 each and Movies are $2.75 each, I hope this helps!
Answer:
a=54
Step-by-step explanation:
Because the problem gives you the value of b simply plug it in the equation a=12b. The new equation should look like this when plugged in: a=12(4.5). Now multiply 12*4.5=54. The new equation would then become a=54

Answer:
C. (y + 3)²/64 - (x + 1)²/36 = 1
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo
My answer:
From the photo, the given information is:
As we know, the hyperbola has general equation for it is:
where h and k are the coordinate for the center (h, k) and we only needed the center of the hyperbola to find our answer.
In this situation, we have:
Hence, we choose C.
Hope it will find you well.
