Answer:
y = 36/5
Step-by-step explanation:
The formula for direct variation is
y = kx where k is a constant
We know y =12 and x= 5
12 = k*5
12/5 = k
The formula is
y = 12/5 x
Now find y = when x=3
y = 12/5 *3
y = 36/5
<h3>f(x) = 119x is the function that represents the number of cupcakes Kathleen has given away over time</h3>
<em><u>Solution:</u></em>
Given that,
Kathleen makes 144 cupcakes each week
Of these she sales 25 each week and gives away the rest
<em><u>To find: Linear function that represents the number of cupcakes Kathleen has given away over time</u></em>
Let "x" be the number of weeks
Number of cakes given away = 144 - 25 = 119
<em><u>Thus, number of cupcakes Kathleen has given away over "x" weeks is given as:</u></em>
f(x) = 119x
Where, f(x) is the number of cupcakes Kathleen has given away over "x" weeks
Answer:
x = 3/4 would be the correct answer.
Step-by-step explanation:
Add four to both sides
Divide both sides by -8
Simplify 6/8 to 3/4
