7(x+1)=63
7 times a number(x) +1
Answer: a)
b)
c)
d) 
Step-by-step explanation:
Since f is an exponential function.
So, it is expressed as

Here f is the present value
p is the initial value
r is the rate of growth per time period
t is the time period.
(a) b represents the 1-unit growth factor for f.

(b) c represents the n n-unit growth factor for f.

(c) d represents the m m-unit growth factor for f.

Write a formula that expresses c in terms of b.
Since
Hence, a)
b)
c)
d) 
Answer:
x = 26, y = 9
Step-by-step explanation:
Add the bottom equations and set them equal to 180
8x -28 = 180
8x = 208 divide each by 8
x = 26
Find the bottom right, 3(26) - 11
78 - 11 = 67
The unlabeled top left box is also equal to 67 degrees.
So 2y + 5 = 23
2y = 18
y = 9
