Answer:

$1,152 Mort will make if he sells 36 necklaces at the local art fair.

Step-by-step explanation:

Unit rates are expressed as the rates as a quantity 1 such that 4 miles per hour or 3 meter per seconds.

As per the given statement: Mort makes beaded necklaces that he sells for $32 each.

⇒ Unit rate per necklace = $32

It is also given that if he sells 36 necklaces at the local art fair.

by definition of unit rate;

\text{Total cost} = \text{Unit rate per necklace} \times 36

Substitute the given values we have;

\text{Total cost} = 32 \times 36 =\$ 1,152

Therefore, $1,152 Mort will make if he sells 36 necklaces at the local art fair.

The question isn’t equal to 90° it’s equal to 180° because the line is straight it’s not a right angle. so when u equal the whole equation to 180°, you get x=18.75. then plug in the number to find the degree of each.
so angle of department would be 139.25° and angle of gas station would be 40.75°

Q1 : Find the inverse of the function.
Mamont248 [21]

Answer:

1. Option D is correct.

2. Option B is correct.

3. Option B is correct.

Step-by-step explanation:

Inverse function defined as the the function that undergoes the action of the other function.

A function f^{-1} is the inverse of f if whenever y =f(x) and x =f^{-1}

To find the inverse of the function:

Q1.

Given the function:  f(x) = 7x -1

Put y for f(x) and solve for x;

y= 7x -1

Add 1 both sides we get;

y + 1 = 7x

Divide both sides by 7 we get;

x = \frac{y+1}{7}

Put f^{-1}(y) for x;

f^{-1}(y) = \frac{y+1}{7}

Interchange y =x, we have

f^{-1}(x) = \frac{x+1}{7}

Q 2.

Given the function:

f(x) = x^3 - 7

Put y for f(x) and solve for x;

y = x^3-7

Add 7 both sides we get;

y + 7 =x^3

taking cube root both sides we get

x =\sqrt[3]{y+7}

Put f^{-1}(y) for x;

f^{-1}(y) =\sqrt[3]{y+7}

Interchange y =x, we have

f^{-1}(x) = \sqrt[3]{x+7}

Q3 .

Given the function:

f(x) = 5x^3 - 3

Put y for f(x) and solve for x;

y = 5x^3-3

Add 3 both sides we get;

y + 3 =5x^3

Divide both sides by 5 we get;

x^3 = \frac{y+3}{5}

taking cube root both sides we get

x = \sqrt[3]{\frac{y+3}{5} }

Put f^{-1}(y) for x;

f^{-1}(y) = \sqrt[3]{\frac{y+3}{5} }

Interchange y =x, we have

f^{-1}(x) = \sqrt[3]{\frac{x+3}{5} }

Whats the answer for 6b+7-2b=1+5b
Alecsey [184]

Solution,6b+7-2b=1+5b\quad :\quad b=6

Steps:

6b+7-2b=1+5b

\mathrm{Group\:like\:terms}, 6b-2b+7=1+5b

\mathrm{Add\:similar\:elements:}\:6b-2b=4b, 4b+7=1+5b

\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides}, 4b+7-7=1+5b-7

\mathrm{Simplify}, 4b=5b-6

\mathrm{Subtract\:}5b\mathrm{\:from\:both\:sides}, 4b-5b=5b-6-5b

\mathrm{Simplify}, -b=-6

\mathrm{Divide\:both\:sides\:by\:}-1, \frac{-b}{-1}=\frac{-6}{-1}

\mathrm{Simplify}, b=6

\mathrm{The\:Correct\:Answer\:is\:b=6}

\mathrm{Hope\:This\:Helps!!!}
