G(x) = 3x² - 5x + 7
b) g(-2) ==> Substitude -2 into x
g(-2) = 3(-2)² - 5(-2) + 7
g(-2) = 12 + 10 + 7
g(-2) = 29
c) g(4) ==> Substitude 4 into x
g(4) = 3(4)² - 5(4) + 7
g(4) = 48 - 20 + 7
g(4) = 35
d) g(-x) ==> Substitude -x into x
g(-x) = 3(-x)² - 5(-x) + 7
g(-x) = -3x² + 5x + 7
e) g(1 - t) ==> Substitude 1 - t into x
g(1 - t) = 3(1 - t)² - 5(1 - t) + 7
g(1 - t) = 3(1 - 2t + t²) - 5 + 5t + 7
g(1 - t) = 3 - 6t + 3t² - 5 + 5t + 7
g(1 - t) = 3t² - t + 5
B. The equation has one real root.
Answer:
Step-by-step explanation:
(x) = expenses, t (y) = total cost
independent (x) - expenses,
dependent (y) - total cost
Answer:
u as the subject of the given formula is, 
Step-by-step explanation:
Given;
v² = u²+2as
To make u the subject of the formula, the following steps are taken;
v² = u²+2as
v² - 2as = u²
take the square - root of both sides of the equation;
Thus, u as the subject of the given formula is,
Answer:
C
Step-by-step explanation:
The answer to this problem is 3 11/12.
1.8 3/4= 8 9/12
2.4 5/6 = 4 10/12
if you minus the two numbers, you get 3 11/12.
