If f(x) = 4x + 21 and g(x) = 2x + 2 what is f[g(7)]
Nana76 [90]

Answer:

we conclude:

 f(g(7)) =85

Step-by-step explanation:

Given

f(x) = 4x + 21

g(x) = 2x + 2

To determine

f(g(7)) =?

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

g(x) = 2x + 2

g(7) = 2(7) + 2

g(7) = 14 + 2

g(7) = 16

so now we have

f(g(7)) =f(16)

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

f(x) = 4x + 21

f(16) = 4(16) + 21

f(16) = 64 + 21

f(16) = 85

so we have

f(g(7)) =f(16)=85

Therefore, we conclude:

 f(g(7)) =85

Anyone know the answer to this one ?
lys-0071 [83]

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

Rachel multiplied each side of x ≥ 2 by 3. She wrote the result as 3x ≤ 6. Explain the error Rachel made.
andrey2020 [161]

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.
