Answer:
x³ - 2x² - 3x + 36
Step-by-step explanation:
(x + 3)(x² - 5x + 12)
Each term in the second factor is multiplied by each term in the first factor , that is
x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis
= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms
= x³ - 2x² - 3x + 36
Answer:
2 3/4 or 2.75
Step-by-step explanation:
Cross multiply
1 ×
16 44
44 × 1 = 44
44÷ 16 = 2 12/16
Simplify 12/16
12÷4= 3
16÷4= 4
2 3/4
B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
Answer:
C
Step-by-step explanation
Why does C work:
You can calculate the rate of change by subtracting 12 from Distance Traveled = 1, from 12.75 from Distance Traveled = 2 to find the difference of 0.75.
Because the multiple-choice only offers fractions you can check if .75 is correct by converting it into a fraction. This is true, 0.75 is equal to 3/4.
Now that you know the rate of change you need to find the initial value which would be Distance Traveled = 0 and Time = __. To find this you subtract 0.75 from 12 which would give you 11.25.
C. y = 3/4(0.75) + 11.25
