That is a rational number.
Answer:
the first one is 4 and 5
Step-by-step explanation:
the second one is 45 because 15+15+15 is 45, you get 15 by the square root of 225
There is no question. I’m sorry :(. Can you mark me as brainliest so I can help more people !!?
Answer:
a) z=5w-3
we have w, so we multiply it by 5 to make it 5w
and then we subtract 3 to make it 5w-3
w⇒ ×5 ⇒ -3 ⇒ z
b) x⇒ +2 = x+2
Now × 7 makes it 7(x+2)
so y=7(x+2)
The graph in the top right—-when trying to figure these out, just plug numbers in for x to find the y.
For example: plug 0 in for x on both equations—
2^0 -1=0 so you get it passing thru 0,0
0+2=2 so it passes through 0,2
