PLEASE HELP!!! HURRY EMERGENCY !! 50 PTS AND BRAINLIEST
makkiz [27]

Answer:

graph of h(x)= a slope of 2, and the y-intercept is 0.

graph of g(x)= a slope of 1, and a y-intercept of 6.

graph of f(x)= a slope of 1, and a y-intercept of -6.

Step-by-step explanation:

The equation would be h(x)=(x-6)+(x+6) which is also equal to h(x)= 2x if you combine like terms. f(x) and g(x) equations are pretty straight forward.

Naddika [18.5K]
<span>At the city park there were 15 blue jays, 6 cardinals, and 9 mockingbirds. 

6 mockingbirds is 2/3 of 9
so 2/3 of 6 is 4 cardinals 

5 blue jays is 1/3 of 15
so 1/3 of 6 cardinals is 2 cardinals

There are 20 cardinals, how many mockingbirds.
the ratio is 2/3, so 20/30 is your answer

hope this helps</span>
