graph the function f(x)=4x-7

Answer:

-22 + (-16)= -38

Step-by-step explanation:

Answer

-38

Explanation

This is the expression given.

-22+(-16)

Adding a negative number to something is the same thing as subtracting the number.

-22-16

To subtract two negative numbers, you are technically adding the numbers and putting a negative sign.

22+16=38

And put a negative sign in front of that.

So the answer would be -38.

Hey there!

The answer is $48.44

We can solve this by first finding how much the discount is.

0.25 x 59.80

14.95

The amount of the discount is 14.95, so we then take the discount off.

59.80 - 14.95

44.85

Then, we find the amount of tax.

.08 x 44.85

3.588 (round to nearest cent = 3.59)

Then, add the price of the tax onto the price of the jeans.

3.59 + 44.85

48.44

Hope this helps! Good luck!

Answer: B

Answer:

y = 43, z = 16

Step-by-step explanation:

congruent essentially means they're the same. If you mentally map one triangle onto the other, you'll see that 43, the hypotenuse, lines up with y, and 16 lines up with z.

Answer:

nth term =  2n^2

Step-by-step explanation:

The computation of the nth term of the quadratic sequence is as follows;

The given sequence is 2,8,18,32,50

Now

The first term, n = 1 = 2 × 1 × 1 = 2

Second term, n =2 = 2 × 2 × 2 = 8

Third, n =3  = 2 × 3 × 3 = 18

fourth term, n = 4,  = 2 × 4 × 4 = 32

fifth term, n =5,  = 2 × 5 × 5 = 50

Now finally  For nth term,  =  2  × n × n = 2n^2

Therefore nth term =  2n^2

Answer: 66 weeks

Step-by-step explanation:

It will take approximately 3 weeks for the business to reach 75% awareness.

The compound annual growth rate (CAGR) is the annualized average rate of revenue growth between two given years, assuming growth takes place at an exponentially compounded rate.

here, we have,

To solve this problem, we can use the formula for compound growth:

E = B x (1 + R)^T

where E is the ending value (75% awareness in this case),

B is the beginning value (3% awareness),

R is the rate of growth (5%),

and T is the amount of time.

We can rearrange the formula to solve for T:

T = log(E/B) / log(1+R).

Plugging in the values from the problem, we get:

T = log(75/3) / log(1+5)

Calculating this out, we get:

T = 3.49 / 1.61

This simplifies to T = 2.16.

Since T represents the amount of time, we can round this up to 3 weeks. Therefore, it will take approximately 3 weeks for the business to reach 75% awareness.

Answer:

$55.50 for three shirts

Step-by-step explanation:

The computation is shown below:

For this question we calculate the average for both the options

For the first option, the average is

= $55.50 ÷ 3 shirts

= $18.50 per shirt

For the second option, the average is

= $79.99 ÷ 5 shirts

= $15.998 per shirt

As per the above calculation, the first option is to be best deal as the amount per shirt is high so the same is to be selected

Step-by-step explanation:

You just convert it :)

Let's take this problem step-by-step:

            ⇒ thus we move the whole thing to the denominator

                     [tex]x^{-\frac{5}{3} } =\frac{1}{x^{\frac{5}{3} } }[/tex]

           ⇒ '3' which is on the denominator of the fraction

               ⇒represents the '3rd' root of x or the cubic root of x

           ⇒ 5 which is the numerator of the fraction is

               ⇒represents the 5th power of x or x to the power of 5

            Result: [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]

Answer: The second choice or  [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]

Answer:

c)462m

Step-by-step explanation:

If a person walks round the park, the person would be walking the whole perimeter of the trail

Perimeter = 2 x (length + breadth)

2 x (30m + 47m) = 154m

If he walks three times, the distance covered = 154m x 3 = 462m

Answer:

Each child ticket costs £2

Each adult ticket costs £5

Step-by-step explanation:

Let's define:

C = cost of a child ticket

A = cost of an adult ticket.

We know that:

"3 adult and 4 child tickets cost £23"

This can be written as:

3*A + 4*C = £23

"1 adult and 5 child tickets cost £15"

This can be written as:

1*A + 5*C = £15

Then we have the system of equations:

3*A + 4*C = £23

1*A + 5*C =  £15

To solve it, we start by isolating one of the variables in one of the equations:

Let's isolate A in the second equation:

A = £15 - 5*C

Now let's replace this in the first equation:

3*( £15 - 5*C) + 4*C = £23

Let's solve this for C

£45 - 15*C + 4*C = £23

£45 - 11*C =  £23

£45 - £23 = 11*C

£22 = 11*C

£22/11 = £2 = C

Each child ticket costs £2

And with the equation:

A = £15 - 5*C we can find the price of an adult ticket if we replace the value of C by £2

A = £15 - 5*£2 = £5

Each adult ticket costs £5

Answer:

[tex] \huge \boxed {slope = - 3}[/tex]

Step-by-step explanation:

[tex]m = \frac{rise}{run} [/tex]

The slope is the change of y over the change of x.

[tex]m = \frac{12 - 3}{ - 1 - 2} \\ m = \frac{9}{ - 3} \\ m = - \frac{9}{3} \\ m = - 3[/tex]

Therefore, the slope is -3.
