Step-by-step explanation:
y=2x-5 is in y=mx+b
Where m = slope
To find y-intercept :
Let x =0
Am sorry for doing this but I really need this point
Only if X is 3/4 . Not if it's any other number.
Answer k=16
A recipe says to use 3 cups of flour to make 48 cookies.
the number of cookies made, y, to the number of cups of flour used,x .
Than
y = kx
Where k is the constant of proportionality.
48 = 3k
k = 16
Therefore the constant of proportionality is 16.
Y=-2
You combine like terms which would be -14 and 22. 22-14=8. Then you subtract that from 0. 0-8=-8. Then divide -8 by 4y. -8÷4=-2
