<h3>Answer:</h3>
B) 10 pounds
<h3>Explanation:</h3>
Let x represent the amount of 70¢ candy to be added. The value of the mixture can be written as ...
... 90×30 + 70x = 85×(30+x) . . . . . where 30+x is the total weight of the mix
... 2700 +70x = 2550 +85x
... 150 = 15x . . . . . . add -70x-2550
... 10 = x . . . . . . . . . divide by the coefficient of x
10 pounds of candy at 70¢/lb must be added.

Answer:
a=-26,b=-10,c=-1,d=-2
Step-by-step explanation:
when x=-3
y=-(-3)^2 +4(-3)-5=a
a=-9-12-5
 =-14-12
 =-26
when x=-1
y=-(-1)^2 +4(-1)-5=b
 =-1-4-5
 b=-10
when x=2
y=-(2)^2 +4(2)-5=c
 =-4+8-5
 =-9+8
 c=-1
when x=3
y=-(3)^2 +4(3)-5=d
 =-9+12-5
 =-14+12
d=-2
