It should be C.

The slope formula using 2 point is

m = (y2 - y1) / (x2 - x1)

That's another way of saying C. The problem with B is that it is the upside down of what the slope actually is.

Svet_ta [14]
<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
