the first option is the answer
Step-by-step explanation:
4c + 6a <= 120 [building hours]
4c + 4a <= 100 [testing hours]
4 * 20 + 6 * 6 <= 120
80 + 36 <= 120
116 <= 120
true, they have enough building hours
4 * 20 + 4 * 6 <= 100
80 + 24 <= 100
104 <= 100
false, they won't have enough testing hours
the first option is the answer
factoring:-
f = 4x^2 + 19x - 5 = (4x - 1)(x + 5)
g = 4x^2 - x = x(4x - 1)
(4x - 1) is common, so:-
f/g (x) = (x + 5) / x which is the second choice.
Answer:
A) x = -8
B) x = 3
Step-by-step explanation:
This quadratic is already factored so all we have to do is solve for the zeroes. We can separate the two factors of the quadratic into x-3=0 and x+8=0. Solve for x in both of the equations and we get the zeroes as x = 3 and x = -8.
