Answer:

y = x - 7

Step-by-step explanation:

You take each equation and sub in for x and y.

The first equation would look like this:

16 = 2(23) - 30  Then you answer looks like this:

16 = 16 but if you did that for the second set in the column it looks like this:

18 = 2(25) - 30

18 = 50 - 30

18 = 20 which does not equal canceling the first answer.

And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.

So that leaves only one answer y = x - 7

Hope this helps

Sorry if this answer is long

Number 2 is what I'm stuck on
DENIUS [597]
Let's say that ground level is 0. When she goes down to the basement, she is going -12 feet since each flight of stairs is12 feet. Then she goes up 12 more feet= -12+12=0. She is back at ground level. Then she goes up another 12 feet= 0+12= 12. So I believe the answer is 12 feet.

Answer:

Step-by-step explanation:

from the graph of f(x)

when x=1,f(x)=0

or f(1)=0

when f(x)=2,x=2

for g(x)

when x=6,g(x)=16

or g(6)=16

when g(x)=18,x=32

for h(x)

when x=14

h(x)=27x-7

h(14)=27×14-7=7(27×2-1)=7(54-1)=7×53=371

h(x)=-493

27x-7=-493

27 x=-493+7=-486

3 x=-54

x=-18

for p(t)

when t=94

p(t)=24

p(94)=24

p(t)=67

t=31
