Answer:

JUSTIFICATION↓

∠1 ≅ ∠2 <u>(∵ Vertically-opposite angles are equal)</u>

Step-by-step explanation:

Since ∠1 lies vertically opposite to ∠2 and vice -versa , therefore ∠1 and ∠2 are equal to each other

Slope of the line that passes through points (-3,4) and (5,-1)

Veronika [31]

When hav epoins (x1,y1) and (x2,y2)
slope is (y2-y1)/(x2-x1)

(-3,4) and (5,-1)
slope=(-1-4)/(5-(-3))=-5/(5+3)=-5/8

slope=-5/8

What is the inverse function of f(x) = 25x-3?

Harrizon [31]

Answer:

The answer is

Step-by-step explanation:

$f(x) = 25x - 3$

To find the inverse of f(x) , equate f(x) to y

That's

y = f(x)

We have

$y = 25x - 3$

Next interchange the terms that's x becomes y and y becomes x

$x = 25y - 3$

<u>Next solve for y</u>

Move 3 to the other side of the equation

That's

$25y = x + 3$

<u>Divide both sides by 25</u>

$\frac{25y}{25} = \frac{x + 3}{25}$

We have the final answer as

${f}^{ - 1} (x) = \frac{x +3 }{25}$

Hope this helps you

What is the range of y = (x - 5)^2 – 1?

Setler79 [48]

1. The graph is a parabola.

2. The parabola opens up, because there's no negative number in front of $(x-5)^2$ .

3. The vertext is (5,-1), because of the vertex form.

This means that that -1 will be the least y-value used on the graph and the garph will open up from there.

The range is (-1, infinity) or { y | y > -1 }.

The graphs of f(x) and g(x) are shown below:

Elodia [21]

Answer:

-3.8, 3

Step-by-step explanation:

The solution to a system is where the graph cross each other. If you look to where they intersect to the left of the origin, where x is negative, it appears that they intersect ALMOST at -4, but not quite. So -3.8 is going to have to do since we don't have the equations of either graph to find the exact values of x. To the right of the origin, where x is positive, the graphs cross where x = 3..
