Answer:

One solution (2.25,1.75)

Step-by-step explanation:

Well first we need to graph the following

$y=3x-5$

$y=-x+4$

So look at the image below.

So looking at the image below we can tell that the system only has one solution (2.25,1.75).

70 POINTS Given the function, f (x) = 1/x-1 - 5 , choose the correct transformation.

matrenka [14]

Answer:

right 1, down 5

Step-by-step explanation:

We are given function as

$f(x)=\frac{1}{x-1}-5$

Firstly, we will find parent function

$f(x)=\frac{1}{x}$

We can see that in place of x , we have x-1

so, it is shifted right side by 1 unit

and 5 is subtracted from y-value

so, it is shifted downward by 5 units

right 1, down 5.........Answer

Write the equation in slope intercept form, given x-intercept is -2 and the y-intercept is 3

iren [92.7K]

----------------------------------------------------------------
Given information
----------------------------------------------------------------
x-intercept = -2 , therefore coordinate = (-2. 0)
y intercept = 3, therefore coordinate = (0, 3)

----------------------------------------------------------------
Find Slope
----------------------------------------------------------------
$\boxed {Slope = \frac{Y_2-Y_1}{X_2-X_1} }$

$\boxed {Slope = \frac{3 - 0}{0 -(-2)} }$

$\boxed {Slope = \frac{3}{2} }$

----------------------------------------------------------------
Substitute the slope and the y-intercept into the equation
----------------------------------------------------------------
y = mx + c
y = 3/2 x + 3

----------------------------------------------------------------
Answer : 3/2 x + 3
----------------------------------------------------------------
