Answer 1
Answer:
Hello,
Answer A
10*(x-12) first x-12 (parenthesis) : difference of some number and 12 second 10* the result before==> the product of 10 by the diffrence of x and 12.
I believe in this item, we are asked to determine how many 5's should be added together in order to form 100. This is calculated by dividing 100 by 5. The answer by completing the operation would be equal to 20. Hence, the answer is 20.

Given f(x) = x - 10. What is f(-7) ?
Answers
f(x) = x-10
f(-7) = -7 -10
f(-7)= -17
I understand now !
f(x)= x - 10
f(-7) = - 7 - 10
f(-7) = - 17
Find the function rule for g(x). The function f(x) = x2 . The graph of g(x) is f(x) translated to the right 8 units and down 7 units. What is the function rule for g(x)? A. g(x) = (x + 7)2 + 8 B. g(x) = (x + 8)2 + 7 C. g(x) = (x - 7)2 - 8 D. g(x) = (x - 8)2 - 7
Answers
f(x)=x^2 Translated to the right 8 units: h(x)=(x-8)^2 and down 7 units: g(x)=(x-8)^2-7
Answer: Option D. g(x)=(x-8)^2-7

*We can to find the upper limit of the data by using the values given in the options. If 2 the upper limit is 8 + 2*0.7 = 9.4
If 1 the upper limit is 8 + 1*0.7 = 8.7
If 0 the upper limits is 8+ 0*0.7 = 8
If 3 the upper limit is 8 + 3*0.7 = 10.1
Therefore, the answer is 3 since all the values are included
