If two angles are both vertical and supplementary, then the angles are

Answers

Answer 1

Answer:

we know that

Supplementary angles are those angles whose sum is equal to $180$ degrees and vertical angles are angles that are congruent.

Let

x--------> the first angle

y--------> the second angle

$x=y$ --------> equation $1$

$x+y=180$ --------> equation $2$

Substitute equation $1$ in equation $2$

$x+[x]=180$

$2x=180$

$x=90$

$y=90$

therefore

the answer is

the angles are right angles

Answer 2

Answer: ur answer would be RIGHT angle!!!

Hope its right!

Which ordered pair is the solution to the system of linear equations y = negative 7 x + 2 and y = 9 x minus 14? (negative 5, 1) (1, negative 5) (5, negative 1) (Negative 1, 5)

Answers

Answer:

B. $(1,-5)$

Step-by-step explanation:

We have been given a system of equations. We are asked to choose the ordered par that is the solution to the given system.

$y=-7x+2...(1)$

$y=9x-14...(2)$

To solve our given system, we will equate both equations as:

$9x-14=-7x+2$

Combine like terms:

$9x+7x-14+14=-7x+7x+2+14$

$16x=16$

$x=(16)/(16)=1$

Upon substituting $x=1$ in equation (1), we will get:

$y=-7(1)+2\n\ny=-7+2\n\ny=-5$

Therefore, the ordered pair $(1,-5)$ is the solution of the given system and option B is the correct choice.

What is the slope of a line perpendicular to 24x-9y=63

Answers

In order to find the slop it is probably best to put the equation in y=mx+b form. This means to get y by itself on one side.
24x-9y=63 will then become -9y=63-24x in which y has been isolated.
Then you should divided by -9 to get the final form: y=24x/9 -63/9.
Now you can get the slope of the perpendicular line by taking the slope of the original equation and finding its reciprocal which is -9/24x. This is your answer.

Jason has decided to sell one of his baseball cards. The card is valued at $51.00. The store is only offering Jason $29.00. How much less is Jason being offered for his card than what it is valued at?*

Answers

well, just take the difference, 51-29, and 22 is how much less his card it being valued at. Or you can do 29-55, which would be -22, showing the amount and that it's valued less.

use the given conditions to write an equation for the line in point slope form passing through (-5,7) and (-8,6)

Answers

point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point

slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3

pick any point
(x,y)
(-5,7)

y-7=1/3(x+5) or
y-6=1/3(x+8)
