Lets x = Mary's age

Emily is there years older than twice her sister Mary's age = 2x + 3

Sum of both is less than 30:

x + 2x + 3 < 30

Solve for x

3x + 3 < 30

3x < 27

x < 9

Mary's age = 9

Inequality represents Mary's possible age:

0 < x < 9

Answer is the second one

0 < x < 9

Find the slope of the line that passes through G(−3, 2) and H(7, 2).
Svetllana [295]

Answer:

y=0x+2 meaning the slope is equal to 0

Step-by-step explanation:

If you think about this question you'll see that our two points have the same y coordinate

This means that the slope is equal to 0

so we have

y=0x+b  

If we plug in -3 for x and set the equation equal to 2 we can find b

0+b=2

b=2

so we have

0x+b=y

Hope this helps!
