For the function g(x)=3x^2-3x-9 what is the value of g(4)

1 answer:

3 0

G(4) = 3x^2 - 3x - 9

Since the g(4) would be g(x) if you didn't know the number. So, substitute all of the x's for 4.

g(4) = 3(4)^2 - 3(4) - 9

g(4) = 3(16) - 12 - 9

g(4) = 48 - 3

g(4) = 45

I hope this helps you!

What is the coefficient of the c-term of the algebraic expression 14a - 72r - c - 34d? A) -34

natima [27]

When the coefficient of a term is 1 or -1, we don't write it, we just use the + or - sign. The coefficient of the c term is -1, because of the - sign in front of it and the lack of written coefficient. Any questions?

Paige lives 3 miles east of her school. Diego lives 8 miles wes of the school. Which expression represents the distance, in mile

True [87]

Answer: |3-(-8)|

Step-by-step explanation:

Given: Paige lives 3 miles east of her school. Diego lives 8 miles west of the school.

From the picture , the number line represents the position of the houses of the two friends such that position of Paige is 3 but position of Diego is (-8) [since east and west are opposite directions]

We know that, Distance between any two points from A to B= B-A

Since distance is a positive quantity, thus

The distance between them = $|3-(-8)|$ miles=11 miles
