15x2

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(4 • (x2)) 7y

—————————— • ————————

5y (22•3x4)

Step 2 :

7y

Simplify ————————

(22•3x4)

Equation at the end of step 2 :

(4 • (x2)) 7y

—————————— • ————

5y 12x4

Step 3 :

Equation at the end of step 3 :

22x2 7y

———— • ————

5y 12x4

Step 4 :

22x2

Simplify ————

5y

Equation at the end of step 4 :

4x2 7y

——— • ————

5y 12x4

Step 5 :

Dividing exponential expressions :

5.1 x2 divided by x4 = x(2 - 4) = x(-2) = 1/x2

Canceling Out :

5.2 Canceling out y as it appears on both sides of the fraction line

Final result :

The function f(x) = { x + 1 is used to complete this Which statements are true of the given function? Check all that apply. tabl

Dmitry [639]

Answer:

Options (1) and (5)

Step-by-step explanation:

Expression that defines the function is,

$f(x)=\frac{1}{2}x+\frac{3}{2}$

Option 1

$f(-\frac{1}{2})=\frac{1}{2}(-\frac{1}{2})+\frac{3}{2}$

$=-\frac{1}{4}+\frac{3}{2}$

$=-\frac{1}{4}+1+\frac{1}{2}$

$=1+\frac{1}{4}$

$=1\frac{1}{4}$

So, $f(-\frac{1}{2} )=-2$ is false.

Option 2

f(0) = $\frac{1}{2}(0)+\frac{3}{2}$

= $\frac{3}{2}$

True.

Option 3

f(1) = $\frac{1}{2}(1)+\frac{3}{2}$

= $\frac{3+1}{2}$

= 2

Therefore, f(1) = -1 is false.

Option 4

$f(2)=\frac{1}{2}(2)+\frac{3}{2}$

$=1+1+\frac{1}{2}$

$=2\frac{1}{2}$

Therefore, f(2) = 1 is false.

Option 5

f(4) $=\frac{1}{2}(4)+\frac{3}{2}$

$=2+\frac{3}{2}$

$=\frac{4+3}{2}$

$=\frac{7}{2}$

True.

Options (1) and (5) are the correct options.

What is x equal to in this equation 5x-20<-5

kari74 [83]

The solution to given inequality is:

x<3

Step-by-step explanation:

We have to solve the given inequality to get the value of x

Given inequality is:

$5x-20$

Adding 20 on both sides

$5x-20+20$

Dividing both sides by 5

$\frac{5x}{5}$

The solution to given inequality is:

x<3

x will be equal to all values less than 3

You have $60 and your sister has $120. You are saving $14 per week and your sister is saving $10 per week. How long will it be b

tigry1 [53]

Answer:

15 weeks

The amount of money is 270

Step-by-step explanation:

You: 60 +14x

Sister: 120+10x

Set them equal to each other

60+14x = 120+10x

Subtract 10x from each side

60+4x= 120

Subtract 60 from each side

4x= 60

Divide by 4

4x/4 = 60/4

x = 15

15 weeks

The amount of money is 120+10*15 = 120+150 = 270
