Answer 1

Answer: With the equation being negative you would multiply it to most likely get a positive if Z is Negative. If Z is a positive but also a higher number the equation is defenitly positive. I dont know the exact answer do to the fact that you didint show the whole question.

WILL GIVE BRAINLIEST!

Answers

Answer:

B

Step-by-step explanation:

So first off, the question is saying to find the difference so that means you subtract. Then it says that the number has to be at least 15 so that means that the inequality sign is greater than or equal to. Since you are subtracting you must add 13 to both sides to cancel it out and x would equal 15+13. So that makes the inequality true since the total is 28. You see if the answer would've been the first one then, the inequality would not have been true since the number 2 is not at least the number 15. Hope this helps

50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?​

Answers

Answer:

B. y = 3x

Step-by-step explanation:

Use one of the points on the graph to find the equation.

Let's take the point (1,3)

We know the proportional relationship is:

y = kx, where k is the coefficient of proportionality

Substitute the values from the point and solve for k:

3 = 1*kk = 3

The function is:

y = 3x

Correct choice is B

Answer:

The graph is in a proportional relationship (given)

Therefore, it is in the form y=kx where k is a constant.......(i)

Now in the graph we can locate that when the value of x is 1, the value of y will be 3

Putting the value of x and y in equation (i), we get

3=1×k

k=3

Now, putting the value of k in equation (i), we get

The equation of the graph is y=3x.

★ B. y=3x is the right answer.

A student bought shoes online. The total cost, t, of the pairs of shoes, s, can be found by the function below. If the student spent $569.37 on shoes, how many pairs did he buy?
t = 62.50x +7.23

Answers

Answer:

D 9

Step-by-step explanation:

569.37 = 62.50x + 7.23

562.14 = 62.5x

x = 9.04 so 9 pairs

The student bought 9 pairs of shoes.

What is a function?

"It defines a relation between one variable and another variable."

What is a linear function?

"It is a function of the form f(x) = ax + b, where a, b are real numbers."

For given example,

The total cost, t, of the pairs of shoes, 'x', can be found by the linear function below.

t = 62.50x +7.23

the student spent $569.37 on shoes,

⇒ t = $569.37

We need to find the number of pairs of shoes the student bought.

Substitute t = 569.37 in the given linear function and find the value of 'x'

⇒  569.37 = 62.50x + 7.23

⇒  562.14 = 62.50x

⇒ x = (562.14) / (62.50)

⇒ x = 8.99

⇒ x ≈ 9

Therefore, the student bought 9 pairs of shoes.
