4x-8=2x+14

subtract 2x on both sides and add 8 on both sides so x=11

Answer:

x = 11

Explanation:

4(x − 2) = 2(x + 7)

Step 1: Simplify both sides of the equation

4(x − 2) = 2(x + 7)

(4)(x) + (4)(−2) = (2)(x) + (2)(7) (Distribute)

4x + −8 = 2x + 14

4x − 8 = 2x + 14

Step 2: Subtract 2x from both sides

4x − 8 − 2x = 2x + 14 − 2x

2x − 8 = 14

Step 3: Add 8 to both sides

2x − 8 + 8 = 14 + 8

2x = 22

Step 4: Divide both sides by 2

2x / 2 = 22 / 2

x = 11

Given f(x)= -3/4x-6 and its domain: (-8, 0, 4) what is the range of the function?

Yanka [14]

The range of function is { 0, -6, -9}

<h3>Solution:</h3>

Given that the function is:

$f(x) = \frac{-3}{4}x - 6$

Also given its domain is (-8, 0, 4)

To find: Range of the function

Domain of the function is possible input of the function that is "x" and range of the function is possible output of the function that is f(x)

As there are only three input values for "x" that are (-8, 0, 4) we can determine the range by calculating value of f(x) for each of the x

For x = 8:

$f(-8)=\frac{-3}{4} \times(-8)-6=6-6=0$

$f(-8)=0$

For x = 0:

$\begin{array}{l}{f(0)=\frac{-3}{4} \times(0)-6=-6} \\\\ {f(0)=-6}\end{array}$

For x = 4:

$\begin{array}{l}{f(4)=\frac{-3}{4} \times(4)-6=-3-6=-9} \\\\ {f(4)=-9}\end{array}$

Thus the range of function is { 0, -6, -9}

Choices for Question #1:

hodyreva [135]

Answer:

Question #1 choice A x=3, ST=24 and Question #2 choice C x =12

Step-by-step explanation:

Question #1

T midpoint so ST=TU and 8x = 2x+18

8x =2x+18

8x-2x=18

6x=18

x=18/6

x=3

so ST= 8x=8*3=24

choice A

Question #2

M midpoint of AB so AM=MB and 4x+1=7x-35

4x+1=7x-35

1+35=7x-4x

36=3x

36/3=x

12=x

choice C

Last year, 210 middle school students

Anit [1.1K]

Answer:

Step-by-step explanation:

let,

this year population of students (pt)= 195

last year population of students (p)= 210

time(t)= 1 year

Population Change( R)= ?

we have,

pt= p( 1 - R/100)^t

195 = 210 ( 1 - R/100)^1

0.92= 1 - R/100

0.92-1= R/100

- 0.08 = - R/100

R= 0.08×100

R= 8%
