X^2 + 3x = 24

completing the square
(x + 1.5)^2 - 2.25 = 24

(x + 1.5)^2 = 26.25

x + 1.5 = +/- sqrt26.25 = +- 5.123

x = -1.5 + 5.123 = 3.62 to nearest hundredth and

x = -1.5 - 5.123 = -6.62 to nearest hundredth

solution set is {-6.62, 3.62}

Answer:

use this equation: 150=1x+0.5y

Step-by-step explanation:

a) standard form equation above

b) 150=1x+0.5y

subtract 1x from both sides

then divide all by 0.5 to get slope intercept form

c) plug it in: 150=1(40)+0.5y and solve to get 220

d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
