Answer:
When x=2
Step-by-step explanation:
Well in the first one it tells you that 2x is 90.
In the second it's y=40x+10
So you plug 2 in as the x.
y=40(2)+10
y=80+10
y=90
Hope this helps
Answer:
c
Step-by-step explanation:
Let’s estimate the students to 20 and the dollars to 25 so you would multiply 20 by 25 which equals 500 so $500 would be your answer
If y = x+2 and x = -3 then we can say that y = -3+2 after replacing the 'x' with -3
From here, we just add -3 and 2 to get -1 which is why y = -3+2 turns into y = -1
So together x = -3 and y = -1
They pair up to form (x,y) = (-3,-1)
