This is the last one i think

I believe the answer is y=3x -4

the slope is 3 because the y value increases by 3

Y = -4/3x − 1<br> y = 1/3x + 4

Tom [10]

Answer:

x = -3, y =3

Step-by-step explanation:

y = -4/3x - 1

y = 1/3x + 4 -------> 4y = 4/3x + 16

Adding the first equation and the new second equation together:

5y = 15 ------> y = 3

Plug y = 3 into one of the original equations:

3 = 1/3x + 4

-1 = 1/3x

x = -3

Answer: b) {-3, 0.5}

Step-by-step explanation:

The new equation is the original equation plus 6. Move the original graph UP 6 units. The solutions are where it crosses the x-axis.

$\text{Original equation:}\quad f(x)=\dfrac{15}{x}-\dfrac{9}{x^2}\\\\\\\text{New equation:}\quad\dfrac{15}{x}+6=\dfrac{9}{x^2}\\\\\\.\qquad \qquad f(x)= \dfrac{15}{x}-\dfrac{9}{x^2}+6$

+6 means it is a transformation UP 6 units.

Solutions are where it crosses the x-axis.

The curve now crosses the x-axis at x = -3 and x = 0.5.
