Answer:

(1,-2) and (0,-5) (There are an infinite amount more)

Step-by-step explanation:

The easiest way to find solutions is to plug in an x value. Let's try 1:

y = 3(1) - 5⇒y = 3 - 5⇒y = -2

(1,-2)

Let's try 0:

y = 3(0) - 5⇒y = 0 - 5 ⇒y = -5

(0,-5)

First, you need to find the total amount they discounted.

3.66 X 3= $10.97

Since they took off that much, you need to add that to the total cost, which was 62. 31

62.31 + 10.97= $73.29

Finally, to find how much each individual shirt cost, you divided it by 3.

73.29 / 3= $24. 43

The answer is C

gtnhenbr [62]

Answer:

3.008 km or 3.0 km

Step-by-step explanation:

According to the Pythagoras theorem:

${c}^{2} = {a}^{2} + {b}^{2} \\ \therefore \: {a}^{2} = {c}^{2} - {b}^{2} \\ \therefore \: {a}^{2} = {(9.3)}^{2} - {(8.8)}^{2} \\ \therefore \: {a}^{2} = {(9.3 + 8.8)}{(9.3 - 8.8)} \\ \therefore \: {a}^{2} = 18.1 \times 0.5 \\ \therefore \: {a}^{2} = 9.05 \\ \therefore \: {a} = \sqrt{9.05} \\ \therefore \: {a} = 3.00832179 \\ \therefore \: {a} = 3.0 \: km$

What is the measure of x?ztХ.ГУ49x = [?]=Give your answer in simplest form.Enter

MAVERICK [17]

Answer:

Explanation:

We can notice that the triangles formed are similar to the original triangle since an altitude is drawn from the right angle.

To find the measure of x, we use ratio:

Triangle 1:

Triangle 2:

So, we use the formula:

$\frac{\text{Shorter leg in Triangle 1}}{\text{Shorter leg in Triangle 2}}=\frac{\text{hypotenuse in Triangle 1}}{\text{hypotenuse in Triangle 2}}$

We plug in what we know:

$\begin{gathered} \frac{\text{Shorter leg in Triangle 1}}{\text{Shorter leg in Triangle 2}}=\frac{\text{hypotenuse in Triangle 1}}{\text{hypotenuse in Triangle 2}} \\ \frac{4}{x}=\frac{x}{13} \\ \text{Simplify and rearrange} \\ (x)(x)=(4)(13) \\ x^2=52 \\ x=\sqrt[]{52} \\ x=2\sqrt[]{13} \end{gathered}$

Therefore, the answer is:

$x=2\sqrt[]{13}$

Answer:

correct amount- 31.63

what you got- 63.31

Step-by-step explanation:

Im not good at explaining but i'll write out a step by step process

100b+.01a-.05=2a+2b

100b+.01a .05=2a+2b

100b-2b=2a- .01a+ .05

98b= 1.99a+ .05

b= (1.99a+ .05)/98

a=31

b=.63

63.26 is twice as much as 31.63

we go to the same school btw :)
