Answer:
we conclude:

Step-by-step explanation:
Given


To determine
In order to determine f(g(7)), the first step we need to do is to determine g(7)
so substitute x = 7 in g(x) = 2x + 2




so now we have

The next step to do is to substitute x = 16 in f(x) = 4x + 21




so we have

Therefore, we conclude:

Answer: B) y = 2 · 3ˣ
<u>Step-by-step explanation:</u>
We can see that (2, 18) is a point on the graph.
Plug it into the equations to see which one make a true statement.
A) y = 1 · 3ˣ
18 = 1 · 3²
18 = 1 · 9
18 ≠ 9
B) y = 2 · 3ˣ
18 = 2 · 3²
18 = 2 · 9
18 = 18 This works!
C) y = 3 · 2ˣ
18 = 3 · 2²
18 = 3 · 4
18 ≠ 12
D) y = 4 · 3ˣ
18 = 4 · 3²
18 = 4 · 9
18 ≠ 36
I thinks is the first one
Step-by-step explanation:
A=45.5
B= 7 inches
therefore: 45.5/7= 6.5
height is 6.5
Answer:
Her mistake was to change the inequality sign from ≥ to ≤.
The sign only changes when you multiply or divide both sides of an inequality by a negative number.
