Answer: C
<u>Step-by-step explanation:</u>
Replace x with 
and solve.
f(x) = 3x² - 6x - 1
f() = 3()² - 6() - 1
= 3(
) + 4 - 1
= 
+ 3
= + 
= 
The equation that best represents the data that is in the table is y = 5x. You can corroborate it by substituting the x values of the table and verifying that you get the "y" values
Answer:
(4,0),(0,-12)
Step-by-step explanation:
Answer: option D. 2x^2 + (3/2)x - 5
Explanation:
1) polynomials given:
f(x) = x/2 - 2 and g(x) = 2x^2 + x - 3
2) question: find (f + g) (x)
That means that f(x) + g(x), so you have to add up the two polynomials given.
3) x/2 - 2 + 2x^2 + x - 3
4) Combine like terms:
a) terms with x^2: you only have 2x^2, so it is not combined with other term.
b) terms with x: x/2 + x
that is a sum of fractions: x/2 + x = [x + 2x] / 2 = 3x / 2 = (3/2)x
c) constant terms: - 2 + (-3) = - 2 - 3 = - 5
5) Result: 2x^2 + (3/2)x - 5
That is the option d.
Answer:
Last answer, height is 150 ft
Step-by-step explanation:
from the graph, you can clearly see, when T=3, H=150
Which means The firework is at a height of 150 feet
