Y=kx, k is not equal to 0
when y=32,x=3, 32=3k
k=32/3
so y=32/3*x
when y=15, 15=32/3*x
x=45/32
200/5=40
He can buy 40 pens!!
Hope this helps!!
The answer is 4√6 4√x
Sorry if that looks confusing but it means small 4, big 6 and then small 4
Ratio and proportion
convert to inproper fracton first
1 and 1/2=1+1/2=2/2+1/2=3/2
3 and 1/2=3+1/2=6/2+1/2=7/2
3/2dozen=7/2cups
times 2 both sides
3dozen=7cups
divide by 3 both sides
1dozen=7/3cups=2 and 1/3 cup
Answer:
-1/5x -4/5 = y
Step-by-step explanation:
f(x) = -5x -4
y = -5x-4
Switch x and y
x = -5y -4
Solve for y
Add 4
x+4 = -5y
Divide by -5
-1/5x - 4/5 = -5y/-5
-1/5x -4/5 = y
