That means f(x)=kx²
so
f(5)=75=5²k
solve for k
75=5²k
75=25k
divide by 25
3=k
f(x)=3x² is da equation
so
f(4)=3(4)²
f(4)=3(16)
f(4)=48

Step-by-step explanation:
Let's write down every possibility starting by using the largest quantity of $20 bills and we'll go from there, everytime that we get a $10 bill we will split it in the next option into 2 $5 bills. (20)(20)(10) (20)(20)(5)(5)
of is
Solution:
Given of what number is .
Let us first convert the mixed fraction into improper fraction.
Now, let us take the unknown number be x.
Do the cross multiplication.
Now, again change the improper fraction into mixed fraction.
Hence of is .

Step-by-step explanation:
A vertex is where two or more curves, lines, or edges meet
Answer:
Y = 23
Step-by-step explanation:
In the equation (y = -3x + 11) the X is the input value. When you replace this by -4 you will multiply -4*-3 which will give you 12 and then you will want to add 11 as that is your y intercept. Giving the value of your Y a 23, or the point would be (-4,23)
