Answer:
Step-by-step explanation:
If
then
by combining like terms. (I'm thinking you might have mistyped the problem because this representation is weird).

If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items. ☺☺☺☺
That looks like a translation; let's check. We have
A(-5,1), B(-3,7), A'(3,-1), B'(5,5)
If it's a translation by T(x,y) we'd have
A' = A + T
B' = B + T
so
T = A' - A = (3,-1) - (-5,1) = (8,-2)
and also
T = B' - B = (5, 5) - (-3, 7) = (8,-2)
They're the same so we've verified this transformation is a translation by (8,-2), eight right, two down.
Answer:
x = -2
Step-by-step explanation:
Step 1: Define
f(x) = -x - 5
f(x) = -3
Step 2: Substitute and Evaluate
-3 = -x - 5
2 = -x
x = -2
Answer: Your question is written f(x) = -2*(-3+3)+1. I'll assume you need the answer for just the one value of x (-3)? If so, f(-3) = 1.
Step-by-step explanation:
f(x) = -2*(-3+3)+1
f(x) = -2*(0)+1
f(x) = 1
Other values x for the equation f(x) = -2*(x+3)+1:
-2 is -1
1 is -7
3 is -11
