She spent 5% of her money
When you evaluate the function f (x) = 4 • 7 ^ x for x = -1 you get:
f (-1) = 4 * 7 ^ -1
f(-1) = 4* 1/7
f (-1) = 0.5714
The next part of the question is not clear. If it refers to the function at x = 2 then:
f (2) = 4 * 7 ^ (2)
f(2) =4*49
f (2) = 196
If it refers to it in x ^ 2
f (x ^ 2) = 4 * 7 ^ (x ^ 2)
Use the GCF of the terms to write the expression as the product of two factors with integer coefficients.
-2x3 - 4x2 + 4x
Answer:
C. f = 9
Step-by-step explanation:
<u>→Subtract 5 from both sides:</u>
3f + 5 = 32
- 5 - 5
_________
3f = 27
<u>→Divide both sides by 3:</u>
f = 9
Answer:
Answer is in the pic
Step-by-step explanation:
A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.
so originally k (-2,5) m (-3,1) l (1,1)
add 3 to x so
k (1,5) m (0,1) l (4,1)
