Find function inverse of f? F(x)=x+2/7

Answer:

False

Step-by-step explanation:

7 1/2 minus 1.5 is actually 6.  6 is not smaller than 5, so it makes this false.

Answer:

The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age

Step-by-step explanation:

Let us solve the question

Assume that Erik is x years old

∵ Erik is x years old

∵ Erik is [tex]\frac{1}{3}[/tex] as old as Dawn

→ That means x = [tex]\frac{1}{3}[/tex] Dawn

∴ x = [tex]\frac{1}{3}[/tex] Dawn

→ Multiply both sides by 3

∴ 3x = Dawn

∴ Dawn is 3x years old

∵ Jiro is 4 years younger than Erik

→ That means Jiro = x - 4

∴ Jiro is (x - 4) years old

∵ Alita is 2 times as old as Jiro

→ That means Alita = 2 × (x - 4)

∴ Alita = 2 × (x - 4)

∴ Alita is 2(x - 4) years old

∵ The sum of all their ages is 72

→ That means add their ages and equate the sum by 72

∴ Erike's age + Dawn's age + Jiro's age + Alita's age = 72

∴ x + 3x + (x - 4) + 2(x - 4) = 72

The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age

Answer:

c. -3

Step-by-step explanation:

- 7x + 6= 27 [subtract 6 from both sides]

-7x = 21 [divide by -7 to isolate x]

x = -3

Answer:

The answer is C

Pay attention, here's why.

Step-by-step explanation:

Let's solve your equation.

−7x+6=27

Step 1: Subtract 6 from both sides.

−7x+6−6=27−6

−7x=21

Step 2: Divide both sides by -7.

−7x /−7 = 21/ −7

x=-3

Answer: See explanation

Step-by-step explanation:

Since Veronica buys 2 games for $30.00 each and a game controller for $19.59. The total cost to be paid will be:

= (2 × $30.00) + $19.59

= $60.00 + $19.59

= $79.59

Since Veronica lives in San Jose, California, where sales tax is 9.25%, the sales tax will be:

= 9.25% × $79.59

= 0.0925 × $79.59

= $7.36

Total amount paid = $79.59 + $7.36 = $86.95

Answer:

No

Step-by-step explanation:

For a relation to be a function it must have a unique x-value for every y-value. This means that in a function x-values cannot repeat. In this relation, the x-value repeats multiple times, so it is not a function. It is also a vertical line, and vertical lines can never be functions since the x-value is constant and therefore repeats.

Answer:if y=0

Step-by-step explanation: view y as 0, so you have 2*0*(-8+0+7)=0

every number multiplied by 0 is 0 so 2*0 is 0 then in the brackets you will have -1. So the final line is 0*-1=0 like I said every number multiplied for 0 is 0 the equation is true for y=0

Answer:

see explanation

Step-by-step explanation:

The zero product property applies to the product of factors equal to zero

For example

a × b = 0

Since the product of the 2 numbers is zero , then one of the numbers must be zero, that is

a = 0 or b = 0

This can be applied to the product

2y(- 8y + 7) = 0

The 2 values being multiplied are 2y and (- 8y + 7)

Thus one or the other must equal zero, so solve both

2y = 0 ⇒ y = 0, or

- 8y + 7 = 0 ⇒ - 8y = - 7 ⇒ y = [tex]\frac{-7}{-8}[/tex] = [tex]\frac{7}{8}[/tex]

Answer:

y= 3

x=3

Step-by-step explanation:

4(2y-3)-2y=6

8y-12-2y=6

6y-12=6 (add the 12 on both sides)

6y=18 (divide the 6 out)

y=3

solve for x.

x=2(3)-3

x=6-3

x=3

Answer:

71.764  feet

Step-by-step explanation:

See attached the rough sketch for your reference

Step one;

Given data

The angle of elevation= 25°

From the triangular diagram, we can see that the height of the church is the opposite, while the distance of the person from the church is the adjacent

Step two:

Applying SOH CAH TOA

tan∅= opp/adj

tan 25= opp/154

0.466= opp/154

cross multiply

0.466*154= opp

opp= height of church = 71.764  feet

Answer:

$282.5

Step-by-step explanation:

$7.50 * 3= $22.5

$22.5 is the total money that is charged from Javier's bank account.

Subtracting that from his $305, we get:

$305 - $22.5 = $282.5

Therefore, Javier has $282.5 in his bank account at the end of three months.

Hello 928747!

So Javier has $305 to begin with but his bank charges him $7.50 if he has less than $500 in his account.

305 < 500

So, since he has less than $500 he will lose $7.50

305 - 7.50 = 297.50

So after they take $7.50, he will have $297.50

but he had less than $500 for 3 months so they would take x 3 more than $7.50

7.50 x 3 = 22.50

305 - 22.50 = 282.50

After three months, Javier will have $282.50

Answer:

t = 11 months

d = 803

Step-by-step explanation:

d = 935 − 12t

d = 517 + 26t

how many months will the number of DVDs sold equal the number of Blu-ray discs sold

Equate both equations to solve for the number of months

935 − 12t = 517 + 26t

935 - 517 = 26t + 12t

418 = 38t

t = 418 / 38

t = 11 months

How many of each is sold in that month?

d = 935 − 12t

= 935 - 12(11)

= 935 - 132

= 803

d = 517 + 26t

= 517 + 26(11)

= 517 + 286

d = 803

There will be 803 DVDs and Blu-Ray discs sold per month in 803 months.
