(-6)+4= -2
-2+(-10)= -12
Final answer= -12
Explanation: I’m smart
The correct answer would be $204.80 because if she keeps doubling whats in the bank the amount after the $ .20 then it would be doubled to $ .40 and so on
Answer:
"f(x) = (x + 3)(x – 7)"
Step-by-step explanation:
If the vertex is (h,k), then the quadratic is can be written in the form:
y = a (x-h)^2 + k
So it will be:
y = a(x-2)^2 - 25
Now, to find a, we need the x-intercept (which is 7), so we plug in 7 into x and 0 into y and solve for a:
0 = a(7-2)^2 - 25
0 = a(5)^2 - 25
0 = 25a - 25
a = 1
THus, we can write:
y = (x-2)^2 - 25
Expanding this, we get:
y = x^2 -4x + 4 - 25
y = x^2 - 4x - 21
y = (x-7)(x+3)
THis is correct answer.
Ok if you multiply 7x11 that’s going to make 77$ and he only has 60$ plus with the candies 4x11=44 77+44=121
