<span>A scale factor is a number which scales, or multiplies, some quantity. The ratio of
any two corresponding lengths in two similar geometric figures is also
called a scale factor.
Given a function
which is formed from the parent function
The function

was obtained from the parent function by multiplying the parent function by 3.
Therefore, the scale factor of the function </span><span>
is 3.</span>
Answer:
He does not have enough money for the second veggie cups, he's just about a dollar fifty short.
Step-by-step explanation:
By doing the math problem, you'll see that he is 1.48 short of having the necessary amount of money. Not enough to buy everything he wants.
We are going to make simultaneous equations.
x will be our $3 ice cream and y will be our $5 ice cream
Equation1 ---- x + y = 50 (the sum of all the ice creams they sell)
Equation 2 ---- 3x + 5y = 180 Sum of all the $3 and $5 ice creams is $180
Since we can't solve for both variables we will put one of the variables in terms of the other.
Take x+y=50 and subtract y from both sides. (I could have done subtracted x - it did not matter). Now we have x= ₋ y +50 (negative y +50)
Now I am going to take equation 2 and replace the x with -y +50
3 (-y +50) + 5y = 180
Now I will use the distributive law on the 3 and what's in the parentheses:
-3y + 150 + 5y = 180
Now I will combine like terms (the -3y and the 5y)
2y + 150 = 180
Now subtract 150 from both sides of the equation
2y = 30
Divide both sides by 2
and get y= 15 They sold 15 ice creams that cost $5 each
Since equation 1 is x+y=50 we can replace y with 15
x + 15 = 50 Now subtract 15 from both sides x = 35
Since x represents the $3 ice creams, they sold 35 of those.
Check:
35 X 3 = $105
15 x 5 = + <u>75
</u> $180
