Help me solving number 22 & 24. Thanks:)
aksik [14]

Answer:

Question 22

x intercept is 7

y intercept is 4

The answer is C

Question 24

x intercept is -4

y intercept is 7

The answer is B

Step-by-step explanation:

x and y intercepts are the points at which the graph meets x and y axes.

x and y intercepts can be found the following way,

y intercept - substitute 0 to x

x intercept - substitute 0 to y

Question 22

7y=28-4x

Substitute x=0 to find the y intercept

7y=28-4*0

=7y=28

=y=4

Substitute y=0 to find x intercept

7*0=28-4x

=0=28-4x

=4x=28

=x=7

Therefore,

x intercept is 7

y intercept is 4

The answer is C

<u>Question 24</u>

4y=7x+28

Substitute x=0 to find the y intercept

4y=7*0+28

=4y=28

=y=7

Substitute y=0 to find x intercept

4*0=7x+28

=0=7x+28

=-7x=28

=x=-4

Therefore,

x intercept is -4

y intercept is 7

The answer is B

What is the circumference of circle P?
SashulF [63]

Answer:

14π in

Step-by-step explanation:

Circumference of a circle is 2πr, and since AB is 14(the diameter), splitting that in half gets 7 (the radius). Plug that into the equation and you get:

2*7*π=C

14π=C
