1 answer:
You might be interested in
S(-3,0) & y(1,-3)
you can multiply y by 5 then calculate or you multiply by 5 in the equation
so you take (x) of s and subtract it from 5(x) of y and add it to (y) of s subtarcted from 5(y) of y then make radical for the formula

Answer:
see the procedure
Step-by-step explanation:
Part 1) using proportion
we know that
Miguel needs 4 gallons of milk to make 12 milkshakes
so
Using proportion
Find out how much milk he needs to make 30 milkshakes
Let
x ----> gallons of milk needed
Miguel needs 10 gallons of milk to make 30 milkshakes
Part 2) we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
This problem represent a proportional relationship
Let
x ----> the number of gallons of milk
y ----> the number of milkshakes
we know that
Miguel needs 4 gallons of milk to make 12 milkshakes
so
For x=4, y=12
Find out the constant of proportionality k
substitute the values
The linear equation is equal to
For y=30
substitute in the equation and solve for x
Divide by 3 both sides
