Solve -2 < 2x + 4 < 12 for x

Answers

Answer 1

Answer:

[tex]-3<x<4[/tex]

Step-by-step explanation:

[tex]-2<2x+4<12[/tex]

We want to isolate [tex]x[/tex].

Subtract 4 from all sides:

[tex]-2-4<2x+4-4<12-4[/tex]

[tex]-6<2x<8[/tex]

Divide all sides by 2:

[tex]\frac{-6}{2} <\frac{2x}{2} <\frac{8}{2}[/tex]

[tex]-3<x<4[/tex]

Hope this helped.

Given the function f(x) = 2x + 5, what would the input be with an output of 21

Answers

Given :-

f(x) = 2x + 5

To Find :-

The input when output is 21 .

Answer :-

The given function is ,

f(x) = 2x + 5

Substitute f(x) = 21 ,

21 = 2x + 521 - 5 = 2x 16 = 2x 16/2=xx = 8

Answer:

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

f(x)=2x^2+6x-8,g(x)=-3x-3 find the value of g(f(1))?

Answers

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

5x-7=2x+8 solve for x

Answers

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

5x-7=2x+8
5x-2x=8+7
3x=15
x=5

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

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?

Answers

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

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″.

Answers

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.
