Answer:

$33

Step-by-step explanation:

Given: Addy had 20% off coupon.

           The coupon took $8.25 off of the shirt price.

Lets assume the original cost of shirt be "x".

We know Addy had 20% off coupon, which help to reduce the price of shirt by $8.25.

∴ We can form an equation to know the original price of shirt.

⇒\frac{20}{100} \times x= \$ 8.25

⇒\frac{1}{5} \times x= \$ 8.25

Multiplying both side by 5

⇒x= 8.25\times 5

∴ x= \$ 41.25

Hence, The original cost price of shirt was $41.25.

Next, finding the price paid by Addy for her new shirt by reducing coupon discount from the cost of shirt.

Price paid by Addy for her new shirt= \$ 41.25- \$ 8.25= \$ 33

Hence, Addy paid $33 for her new shirt.

Which best describes the graphs of the line that passes through (−12, 15) and (4, −5), and the line that passes through (−8, −9)
konstantin123 [22]

Answer:

C) They are perpendicular lines.

Step-by-step explanation:

We first need to find the slope of the graph of the lines passing through these points using:

m =  \frac{y_2-y_1}{x_2-x_1}

The slope of the line that passes through (−12, 15) and (4, −5) is

m_{1} =  \frac{ - 5 - 15}{4 -  - 12}

m_{1} =  \frac{ - 20}{16}  =  -  \frac{5}{4}

The slope of the line going through (−8, −9) and (16, 21) is

m_{2} =  \frac{21 -  - 9}{16 -  - 8}

m_{2} =  \frac{21  + 9}{16  + 8}

m_{2} =  \frac{30}{24}  =  \frac{5}{4}

The product of the two slopes is

m_{1} \times m_{2} =  -  \frac{4}{5}  \times  \frac{5}{4}  =  - 1

Since

m_{1} \times m_{2} =  - 1

the two lines are perpendicular.

8. Find GH,<br> E<br> 3-4<br> HY<br> -<br> H<br> 2<br> 3x - 4<br> G<br> SI<br> F<br> 9x - 59<br> D
Ostrovityanka [42]

Answer:

GH= 47

Step-by-step explanation:

2(3x - 4) = 9x - 59

6x - 8 = 9x - 59

6x - 9x =  - 59  + 9

\cfrac{ - 3x}{ - 3}  =  \cfrac{ - 51}{ - 3}

x = 17

gh = 3(17)  - 4

51 - 4

= 47

What is the range of the radical function f(x) = to the square root of x-2 +4
jarptica [38.1K]

Answer:

2,∞

Step-by-step explanation:

For the range, x2 takes its minimum at x=0 , so putting in x =0 gives y=√x2+4=√0+4=2 therefore making the range [2,∞).

Please help I'm so confused :)
Elza [17]

⇒I will first isolate y together with its coefficient k by placing t^{2} to the right hand side...

ky=x+t^{2}

⇒Now to leave y independent we have to divide ky by the coefficient of y which in this case is k.

⇒Meaning k will divide all the terms in the equation.

\frac{ky}{k} =\frac{x}{k} +\frac{t^{2}}{k} \\y=\frac{x}{k} +\frac{t^{2}}{k}

⇒Attached is the answer.
