Answer:
<u><em>6 quarts</em></u>
Step-by-step explanation:
60% 3 gallons = 1.8 gallons of broth
water = 0% broth
1.8=1.2+0.4x
0.6=0.4x
x=1.5
1.5 gallons = 6 quarts
7.6 x 10^-4
y=15
u can find y int by making the value of x=0
so
0^2-5*0+15=y
-22
1) Substitute x and y into the equation:
-3(4) + 2(-5)
2) Simplify:
-12 + (-10)
= -22
