Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y =
when x =
, then
= k(
)² =
k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k = 
y =
x² ← equation of proportion
When y =
, then
=
x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ±
= ± 3
with positive value x = 3 → d
It would be 26 repeating itself
Answer:
y=3/2x-4
Step-by-step explanation:
y=3/2x+b
-1=3/2(2)+b
-1=3+b
-4=b
y=3/2x-4
Equations:
100 + 35m
50 + 35m
Steps:
100 + 35m = 50 + 35m <span>
<em>Set the equations equal to each other.</em>
</span> <span />
<span>
100 + 35m = 50 + 35m <span>
-50 - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.
50+35m=35m
-35m -35m
<em>Subtract 35m from both sides of equation.</em>
50=m
In fifty months, they will have the same amount of money. They will each contain $1850 dollars.
Hope this helps.
