Answer:
58.50
Step-by-step explanation:
First find out how many were vanilla and chocolate
vanilla: 5/6 * 36 = 30
Chocolate = total - vanilla = 36-30 =6
Cost for vanilla = 1.50*30 =45
Cost for chocolate 2.25*6 =13.5
Add the cost together
45+13.50
58.50
Answer:
f(-14)=-15
Step-by-step explanation:
What ever is in the parentheses after the letter (in this case it's f) will be the x value since f(x).
So
f(-4)=5(-4)+5
Then solve.
f(-4)=-20+5
f(-4)=-15
-15
Given function:
y=9.5x+62.1
We have to find the number of minutes x, when y=138.1°F
Put value of y in function.
138.1=9.5x+62.1
Subtract 62.1 from both sides.
76=9.5x
Divide both sides by 9.5.
8=x
or
x=8 minutes
Answer: After 8 minutes the temperature of water will be 138.1°
I dont know if it needs to be in slope intercept of general form so i'll give you both.
Answer:
Slope intercept form- y = -1/4x + 4
General form- 1/4x + Y = 4, or, 1/4x + Y - 4 = 0
