Suppose y varies inversely with x, and y = 32 when x = 4. What is the value of y when x = 8?
bulgar [2K]

Answer:

16

Step-by-step explanation:

Inverse variation is of the form

xy = k where k is a constant

x=4 and y = 32

4*32 = k

128 = k

xy = 128

Let x = 8

8y = 128

Divide each side by 8

8y/8 = 128/8

y =16

Can someone pls help me with this?
lara [203]

Answer:

14 is A

15 is B

Step-by-step explanation:

14 . the answer is a because first off the slope is negative so we can immediately eliminate B and D second of all the slope is 1/2 so we can eliminate D and get that the answer has to be a

15. answer is B for this one because first of all the slope is negative so we can immediately eliminate A and c and second of all the y-intercept would be 120 because 90 is what x=1 so we would have to add 30 to get what y would equal when x=0 if that makes sense

Lilia is saving money for dance lessons. She already has $10. Each week she is going to save $5. Write an equation, in slope-int
katrin [286]

The equation which represents the amount of money, y, that Lilia will save in x weeks is;

  • y =$5x + $10.

<h3>Slope-intercept form of linear equations</h3>

The slope-intercept form of linear equations usually takes the form;

  • y = mx + c

According to the information given;

  • Lilia already has $10.

Therefore, the y-intercept of the equation is; $10.

  • And since she saves $5 each week;

The slope of the equation is; $5.

By substitution, the required equation is;

  • y =$5x + $10.
