Question and answer
In question #2, it says to solve the system by substitution. x = -3y - 8 -2x - 4y = 9 Which is the correct equation after the substitution is made? a 6y- 8 - 4y = 9 b -2(-3y - 8) - 4y = 9 c -2x = 4(-3y - 8) = 9
x=-3y-8_ -2x-4y=9 x=-3y-8_ -2(-3y-8)-4y=9... So B) -2(-3y - 8) - 4y = 9 is the answer.

Solve by elimination. x + y = 30 x - y = 6
Weegy: x+y=30_x-y=6... x=-y+30_x-y=6... x=-y+30_(-y+30)-y=6.... x=-y+30_-y+30-y=6... x=-y+30_-2y+30=6... x=-y+30_-2y=-30+6... x=-y+30_-2y=-24... x=-y+30_-(2y)/(-2)=-(24)/(-2)... x=-y+30_y=-(24)/(-2)... x=-y+30_y=12... x=-(12)+3 [ 0_y=12... x=-12+30_y=12... x=18_y=12... x=18 y=12 is the answer. ] (More)

1.) y = -2x + 4
m = -2, y-int (0, 4)

2.) 2x - 2y = 4
(-2y = -2x + 4)/(-2)
y = x - 2
m = 1, y-int (0, -2)

For question #4 on the worksheet: You will need to combine ______ kg of fruit drink A and ______ kg of fruit drink B
Weegy: The kernel of maize has a pericarp of the fruit fused with the seed ... and the need to ... [ ^ Calculated from 185 bushels per acre at USDA 25.4 kg per ... ] User: 4.) Suppose you want to combine two types of fruit drinks to create 24 kg of a drink that will be 5% sugar by weight. Fruit drink A is 4% sugar by weight, and fruit drink B is 8% sugar by weight. How much of each type of fruit drink will you need to use? Use any method to solve. You will need to combine ______ kg of fruit drink A and ______ kg of fruit drink B Weegy: sugar + sugar = sugar 0.04x + 0.08(24-x) = 0.05*24 - - - - - Multiply thru by 100 to get: 4x + 8*24 - 8x = 5*24 -4x = -3*24 x = 18 kg (amt. of 4% drink) - - 24-x = 6 kg (amt. of 8% drink) (More)
