The scale factor I believe would be 4.2 (I haven’t done this in a while but scale factor would be how much it grows each time)
Answer:
A; B; D; F; G
Step-by-step explanation:
Standard form: Ax+By=C
2y+4=3(y-1)
2y+4=3y-3
4+3=3y-2y
Y=7
X=2
Answer:
k = 4
Step-by-step explanation:
The graph represents y and x in direct proportion with equation
y = kx ← k is the constant of proportionality
To find k use the point (1, 4), that is x = 1, y = 4
k = = = 4
Answer:
90 + x
Step-by-step explanation:
supplementary angles are angles that add up to 180.
90 + 90 = 180
-x + x = 0
90-x + 90 + x = 180.
so, your answer would be 90 + x
Check! lets say X = 6
90-6 + 90 + 6 = 180.
Good luck with your schoolwork/homework!
