Answer:
The 2 numbers are 512.8 and 487.2.
Step-by-step explanation:
Let the numbers be x and y, then:
x + y = 1000............(1)
x^2 - y^2 = 25600
(x + y)(x - y) = 25600
1000(x - y) = 25600
x - y = 25.6............(2)
Adding (1) + (2):
2x = 1025.6
x = 512.8
so y = 1000 - 512.8
y = 487.2.
Answer:
80%
Step-by-step explanation:
I'm assuming you want the average of the class.
62 + 78 + 83 + 84 + 93
= 400
400/5
= 80
Therefore Victor's overall test score is 80%
For q(x) = -2x - 2 and r(x) = x^2 + 2
Find the value of q(r(3)).
This is a problem that asks for you to find a function of a function. First things first, you must understand that it is asking you to plug r(3) into q(x) as the value of x.
Let's start by plugging 3 into r(x). Doing so, you'd get
r(3) = 3^2 + 2
Solve it.
r(3) = 9 + 2
r(3) = 11
You can see now that q(r(3)) is really q(11). Plug it in.
q(r(3)) = -2(11) - 2
Solve it.
q(r(3)) = -22 - 2
q(r(3)) = -24
