Question

Explanation please help

Answer 1

determine the intersection of this two functions.

Answer 2

Graph both, see where they cross.
Check by setting them equal to each other and solving for x.

Answer 3

i believe t could be A which is -6 whch i say because of the negative and what carries the 5

Answer 4

but im not sure at all am i right or wrong or even on the path

Answer 5

You could set up a system of equation and solve for x

\[5x - 45 = -3/2x + 7 \]

Answer 6

I think that you are supposed to graph the two lines, and write down the intersection. They are in slope-interecept form (y=mx+b), y is equal to f(x) and g(x), m is the slope of the line, and b is the y intercept. Again, I am not sure that this is the correct way to do this.

Answer 7

well what is the way you'll do it

Answer 8

well, you can graph the two lines and find the point where they both intersects or you could do it algebraically.

Answer 9

well im not getting any answer for this problem

Answer 10

since f(x) = g(x)

f(x) = 5x -45
g(x) = -3/2x + 7

then,

5x - 45 = -3/2x + 7

combine like terms and you get

5x + 3/2x = 7 + 45

simplfy

13/2x = 52

divide both sides to isolate x.

Answer 11

you should get a whole number

Answer 12

which is 6.5 the first one

Answer 13

A.6

Answer 14

If you are graphing, you should have f(x) as a positive line going through -45 on the y-axis and inclining by going up five and one to the right, and g(x) as a negative line going through 7 on the y-axis and decling by going three down and two to the right. Continue the lines until they intersect, then see where on the x-axis that is. I'm sorry if this is confusing, you might find it easier to do it @coolsday 's way.

Answer 15

it should be 8

Answer 16

because you have 13/2x = 52

divide both sides by 13/2 to isolate x

therefore, x = (52)/(13/2) or 52 x 2/13

Answer 17

oh i se all i did was the division i didn't do the rest like multiply and try out the answer choices
