Answer 1
That is called supplementary angles, so they add up to 180 degrees
So it would be 57 + x + 23 = 180
Add 57 and 23, which is 80, subtract that from 180, and you would get
x = 100

It has to equal 180 degrees but I don't know what it is

Answers

I’m not exactly sure the answer because it doesn’t look like the full question but
(5x + 2) (3x + 2) = 180
15x + 4 = 180

Now, 'when two functions f and g are inverses of each other, they satisfy the property '.

So, we have,

 

Thus, we get for the given function f and g, .

Hence, they are inverse of each other.

B. Now, as we have,

That is, the composition of the functions is equal to the identity function.

Thus, the domain and range are the set of all real numbers respectively.

So, in the interval notation, we have,

25 points What is the equation for the line in slope-intercept form

Answers

Answer:

y=8x

Step-by-step explanation:

x=1 y= 8

x=2 y=16

8=m+b

16=2m+b

m=8

y=8x

Choose 2 coordinates from the line. Let’s pick (0,0) and (2,16)

The equation of a line is on the form y = mx + b where m is the slope and b is the y-intercept.

First let’s find the slope:

m = (y2-y1)/(x2-x1) = (16-0)/(2-0) = 16/2= 8

So we have y = 8x + b

We substitue one of the coordinates to find b. Let’s substitute (0,0)

We get 0 = 0 + b. So b = 0

The equation of the line is y = 8x

2x + 5y = -24

Solve by elimination
y and x

Answers

Answer:

x = -2

y = -4

Step-by-step explanation:

The way systems of equations  work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*

so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.

that would leave

5x = -10

divide both sides by 5

x = -2

Now that we know x = -2, we can plug in -2 into one of the equations to find y.

2 ( -2)  + 5y = -24

-4 + 5y = -24

-4 + 4 + 5y = -24 + 4

5y = -20

y = -4

x = -2

y = -4
