Step-by-step explanation:

g(-2)=2(-2)^2 +7(-2) -4

=8 -14 -4

= -10.

j(20)= -5-4(20)

=-5-80

= -85

G(x) = 2x^2 + 7x - 4
g(-2) = 2(-2)^2 + 7(-2) - 4
= 2(4)+7(-2)-4
= 8-14-4
=-8

dangina [55]

Answer:

  • 25 = 5^2
  • 125 = 5^3

Step-by-step explanation:

Both 25 and 125 are powers of 5. As such, they can be written as the powers they are:

  25 = 5·5 = 5^2

  125 = 25·5 = 5·5·5 = 5^3

The graphs of the functions f(x)=|x-3| + 1 and G(x)=2x + 1 are drawn. which statement about these functions is true?
Roman55 [17]

The only true statement that compares the two functions is:

B: The solution to f(x)=g(x) is 1

<h3>Which statements are correct?</h3>

Here we have the functions:

f(x) = |x - 3| + 1

g(x) = 2x + 1

First, let's find the solution for:

f(x) = g(x)

|x - 3| + 1 = 2x + 1

|x - 3| = 2x

Notice that we have two options, x = 3:

|3 - 3| = 2*3

0 = 6  (x = 3 is not a solution)

And x = 1:

|1 - 3| = 2*1

2 = 2  (x = 1 is a solution).

Now to get the y-value where the graphs intersect, we just evaluate one of the functions in the solution we found above;

f(1) = |1 - 3| + 1  = 2 + 1 = 3

The graphs intersect when y = 3.

Then we conclude that the only true statement is:

B: The solution to f(x)=g(x) is 1
