Question

suppose f(x)=2x-5 and g(x)= l3x-1l find the value of f(1)+g(2) how do i set this equation up?

Answer 1

Hey :)\[\large\rm f(\color{orangered}{x})=2(\color{orangered}{x})-5,\qquad\qquad g(\color{orangered}{x})=|3(\color{orangered}{x})-1|\]

Answer 2

So f(1) means, replace all x's with 1.\[\large\rm f(\color{orangered}{1})=2(\color{orangered}{1})-5\]

Answer 3

Do i also do that with g and then add them together?

Answer 4

Yes! :)

Answer 5

Except you're replacing the x's in g(x) with 2's, ya?

Answer 6

Thank you so much can i also ask you a really quick question?

Answer 7

sure

Answer 8

okay got it :)

Answer 9

i have to graph the inequality 4x-3y<2 but if i solve for y i got a two fractions and i dont know if i should graoh it that way or if theirs another way

Answer 10

graph* theres*

Answer 11

You could instead graph the intercepts,
well it turns out that one of the intercepts is an ugly fraction anyway -_-

ya just stick with solving for y in this case.
You get something like this, ya?\[\large\rm y>\frac{4}{3}x-\frac{2}{3}\]You remembered to flip the inequality sign when you divided the -3 across it?

Answer 12

yea i got exactly that

Answer 13

You can graph your y-intercept, -2/3.
And then just pick another point.

I would recommend plugging in x=-1,
that should give you a nice non-fraction coordinate.

Answer 14

alright i guess i will stick with the fractions. i was just trying to make sure i was doing it right and the most efficient way as possible

Answer 15

Thank you soo much!!! You were of a lot help to me. i appreciate it :D
