Answer:

see attached

Step-by-step explanation:

Find the y-values corresponding to x-values of 0 and 1, then plot those points and draw a line through them.

For x=0, ...

y = -4·0 -1 = -1 . . . . the point is (0, -1) . . . the y-intercept

For x=1, ...

y = -4·1 -1 = -5 . . . . the point is (1, -5)

The attached graph shows these points and the line through them.

ddd [48]

Let $x be the amount of money which Kelci has raised. Brianna has raised 3 times more money than kelci, then she has raised $3x. Totally both have aised $(x+3x)=$4x.

Since together they have raised more than $300, then 4x>300,

$x\ \textgreater \ \dfrac{300}{4}$ .
Answer: the inequality $x\ \textgreater \ \dfrac{300}{4}$ can be used to determine the amount of money kelci has raised

The function f(x) = |x| is shifted to the left 3 units and down 2 units to make the function g(x) . Write the equation g(x) that

Mila [183]

Answer:

g(x) = |x+3|-2

Step-by-step explanation:

to move horizontally replace each x with (x ± c)

if you move it to the right, you need x - c

if you move it to the left , you need x + c

so , since we are moving 3 units to the left, we replace the x with x+3

g(x) = |x+3|-2

HELP PLZ RN<3 which graph displays a rate of change of 2.5?

Ilya [14]

Answer:

The second graph.

Step-by-step explanation:

The first graph has a negative slope, so that can't be the right answer.

The last graph isn't steep enough to show a rate of 2.5.

This leaves us with the middle graph which is correct.

If f(x)= 3x2 and g(x) = x+2, find (f.g)(x).

Paha777 [63]

Step-by-step explanation:

$f(x) = 3 {x}^{2} \: and \: g(x) = x + 2 \\ (f.g)(x) \\ = f(x).g(x) \\ = 3 {x}^{2} .(x + 2) \\ \red{ \boxed{ \bold{ \therefore f(x).g(x)= 3 {x}^{3} + 6 {x}^{2} }}} \\$
