Let x represent the number of quarts of Tuscan sauce and
y represent the number of quarts of marinara sauce Tiffany makes.
A quart of Tuscan sauce requires 6 tomatoes and 1 cup of oil
x quarts requires 6x tomatoes and 1x cups of oil
A quart of her marinara sauce requires 5 tomatoes and 1.25 cups of oil
y quarts requires 5y tomatoes and 1.25 y cups of oil
She has 45 tomatoes and 10 cups of oil on hand.
So the constraints are


x>=0 and y>=0
Try this option (see the attachment). Make design according own requirements.

Answer: 0.030921
Euclid : known as father of geometry
Thales : greek philosopher who contributed 5 theorems of geometry
Pythagoras : had a theorem named after him
Hippocrates : compiled basic geometry facts into a textbook
The total amount of money that Jeff has is $20
total fraction of his expenses on lunch and movies is:
(2/5+1/8)
=21/40
the remaining fraction is:
1-21/40
=19/40
thus the amount of cash that Jeff was left with will be:
19/40×20
=$ 9.5
Step 1: Foil to get y=x^2+3x-10
Step 2: The C of the equation is -10, which is the y-intercept (so the answer is graph A)
Just to check, you can find the x intercepts
x-2=0
x=2
x+5=0
x=-5
