Answer:

X=135 degrees

Step-by-step explanation:

the total interior angle of a triangle is 180.

To work this out you would first add the interior angles of B which is 69 and the interior angle of C which is 66, which gives you 135.

The next step is to minus 135 from 180, which gives you 45. This is because the total interior angle of a triangle is 180.

Then to work out the angle of x you would minus 45 from `180, which gives you 135. This is because the total angle in a straight line is 180 degrees.

1) Add the angles of 69 and 66.

$69+66=135\\$

2) Minus 135 from 180.

$180-135=45$

3) Minus 180 from 45.

$180-45=135 degrees$

What is the equation, in point slope form, of the line

melamori03 [73]

Answer:

y=3/2x+11/2

Step-by-step explanation:

Hello! Sorry I just saw this

Anyways, let's continue

first, we need to find the equation of the line with the one that is (-2,-4) and (2,2)

first, we need to find the slope

the equation for slope is y2-y1/x2-x1

so let's label the points

x1=-2

y1=-4

x2=2

y2=2

now plug it in

2-(-4)/2-(-2)=6/4=3/2

now, let's turn it into a line

the point-slope form is y-y1=m(x-x1) (m=slope)

now, plug it in

y-(-4)=3/2(x-(-2))

simplify to

y+4=3/2(x+2)

turn into y=mx+b format

y+4=3/2x+3

subtract 4 on both sides

y=3/2x-1

Now for the line that is parallel.

Parallel lines have the same slopes, so you automatically know that the new line will be y=3/2x+b

To make sure (-3,1) is a solution to the point, put 1 as y and -3 as x

1=3/2(-3)+b

1=-9/2+b

add 9/2 on both sides

b=11/2 or 5.5

now, put it into the equation

y=3/2x+11/2

Hope this helps!

50 POINTS IF YOU ANSWER CORRECTLY!

melisa1 [442]

Answer:

Problem 4: Option C, 32

Problem 5: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6: x = 17

Problem 7: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Step-by-step explanation:

Problem 4

2 + x + 16 = 50

x + 18 - 18 = 50 - 18

x = 32

Answer: Option C, 32

Problem 5

You need to have the 2 and the x combine. Make the table 2x than 16.

Answer: You need to have the 2 and the x combine. Make the table 2x than 16.

Problem 6

2x + 16 - 16 = 50 - 16

2x / 2 = 34 / 2

x = 17

Answer: x = 17

Problem 7

She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

Answer: She drew a 2, x and an 16. Instead you must have 2x and 16. 2x + 16 = 50

What is the slope of this line?

Brums [2.3K]

Answer:

$slope=\frac{1}{4}$

Step-by-step explanation:

The slope of a line can be seen as:

$\frac{rise}{run}$

Rise over run is the change in the y values over the change in x values. For example, in this graph, you would start on one of the points given. From there, you would move up first. After moving up a certain number of spaces, you would move to the side until you reach the other point.

In the graph, you would move up until you are in line with one of the other points. Starting at (-4,5), move up one space, then to the left 4 spaces to reach the point (0,6). Using the spaces moved in the rise over run:

$\frac{1}{4} =\frac{rise}{run}=slope$

Therefore, the slope is $\frac{1}{4}$ .

This is true for any two points on the line.

:Done

*When you move up, the number will be positive $(\frac{+y}{x} )$ . If you move down, the number will be negative $(\frac{-y}{x} )$ . If you move left, the number will be positive $(\frac{y}{+x})$ . If you move right, the number will be negative $(\frac{y}{-x} )$ . Keep this in mind. It is very important.
