Given the function f(x) = 2x + 5, what would the input be with an output of 21
Given :-
f(x) = 2x + 5To Find :-
The input when output is 21 .Answer :-
The given function is ,
f(x) = 2x + 5Substitute f(x) = 21 ,
21 = 2x + 521 - 5 = 2x 16 = 2x 16/2=xx = 8Answer:
input = 8
Step-by-step explanation:
x is the input and f(x) is the output
Given f(x) = 2x + 5 and f(x) = 21 , then equating gives
2x + 5 = 21 ( subtract 5 from both sides )
2x = 16 ( divide both sides by 2 )
x = 8
That is the input is 8

5x-7=2x+8 solve for x
Answer:
x=5
Step-by-step explanation:
Simplifying 5x + -7 = 2x + 8 Reorder the terms: -7 + 5x = 2x + 8 Reorder the terms: -7 + 5x = 8 + 2x Solving -7 + 5x = 8 + 2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -7 + 5x + -2x = 8 + 2x + -2x Combine like terms: 5x + -2x = 3x -7 + 3x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 -7 + 3x = 8 + 0 -7 + 3x = 8 Add '7' to each side of the equation. -7 + 7 + 3x = 8 + 7 Combine like terms: -7 + 7 = 0 0 + 3x = 8 + 7 3x = 8 + 7 Combine like terms: 8 + 7 = 15 3x = 15 Divide each side by '3'. x = 5 Simplifying x = 5

Answer:
f(x) = 0.5x +4
Step-by-step explanation:
The function rule will replace h with f(x), and d with x:
h = 0.5d +4
f(x) = 0.5x +4
__
The table values are found by putting x into the function rule and doing the arithmetic. For example, for x=1, we have ...
f(1) = 0.5·1 +4 = 0.5 +4 = 4.5
The full table and the graph are shown in the attachment.

f(x)=2x^2+6x-8,g(x)=-3x-3 find the value of g(f(1))?
Answer:
g(f(1)) = -3
Step-by-step explanation:
First calculate f(1). In order to do that, you have to substitute 1 back into every “x” that you see in the “F” function.
F(1) = 2(1)^2+6(1)-8
= 2+6-8
= 0
f(1) = 0
Now that you’ve figured out that f(1) = 0. You can substitute 0 in order to find the answer to your question.
g(f(1)) = g(0) find g(0) the same way you found f(1)
g(0) = -3(0)-3 = -3
g(f(1)) = -3

Answer:
the first six square roots are 1, 3, 10, 5, 8 and 14.
Step-by-step explanation:
You will find yourself using square roots often enough to make it worth the effort to memorize the basic ones.
In the same order as presented here, the first six square roots are 1, 3, 10, 5, 8 and 14. That is, √1 = 1; √9 = 3; √100 = 10; and so on.

Christian has been offered a new job that pays $24,000 a year plus 3% of sales. For what total sales would this new job pay more than his current job which pays $60,000?
Answer:
$1,200,000
Step-by-step explanation:
Let x = sales
Since he gets 3% of a sale, we multiply x by 0.03
24,000 + 0.03x = 60,000
Subtract 24,000 from both sides
24,000 + 0.03x = 60,000
- 24,000 - 24,000
0.03x = 36,0000
Divide both sides by 0.03
0.03x/0.03 = 36,0000/0.03
x = 1,200,000

Larry is on his school's cross-country team. He runs 8 miles during each practice.
Write an equation that shows the relationship between the number of practices Larry attends, x, and the total number of miles he runs, y.
Y=
Answer:
8x=y or y=8x
Step-by-step explanation:
So 8 is the number of hours,
we can interpet x for the amount of practice he goes to. For example if hee goes,
for example if he goes to 2 practices the equation will be =
8(2)=Y.... 8(2)=16
16 is the number of miles he runs for 2 practice
We can insert the number of practice he goes to into X
Complete the table to find the rule for the reflection, the coordinates of triangle A′B′C′, and the coordinates of the reflected image, triangle A″B″C″.
When we reflect a point across an axis, the distance between the point and the axis stays the same, but is flipped to the opposite side.
We know that the coordinates of point A are (4,1), the coordinates of point B are (6,3), and the coordinates of point C are (2,4).
In this case, Triangle ABC is a reflection of point A'B'C' across the y-axis.
= reflection across the y-axis
