Answer:

x=81 degrees z=99 degrees y=68 degrees

Step-by-step explanation:

first we know 36+63+x is 180 degrees by triangle sum ( the sum of the three angles of a triangle is 180) so x would be 81 degrees. then we know x+z=180 degrees by sum of a line( a line is 180 degrees on either side) making z=99 degrees. Then doing triangle sum again we know 13+99+y=180 degrees making y=68 degrees

A line passes through the points (8, –1) and (–4, 2). A coordinate plane. What is the y-intercept of this line?

lora16 [44]

Answer:

y-intercept is 1

Step-by-step explanation:

We need to find the equation of the line first.

<h3>Gradient</h3>

The gradient is found using the formula:

$m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m=\frac{-1-2}{8--4}$

$m=-\frac{1}{4}$

So the equation is y = $-\frac{1}{4}$ x + c

<h3>Finding c</h3>

To find c we need to substitute the value of x and y into the equation:

-1 = $-\frac{8}{4}$ + c

-1 = -2 + c

1 = c

And c is the y-intercept so it is 1

timofeeve [1]

For this case we can make the following rule of three:
23000 -------> 100%
x --------------> 180%
Clearing the value of x we have:
x = (180/100) * (23000)
x = 41400
Answer:
you would expect about:
a) 41,400 responses

A $1,200 computer is losing value at a rate of 22% per year; 2 years

zalisa [80]

Answer:

$730.08

Step-by-step explanation:

22% = 0.22

1 - 0.22 = 0.78

Value after 2 years

v = 1200(0.78)²

v = 730.08

$730.08

PLEASE HELP!! LMNP is rotated 90° clockwise around the origin. What are the coordinates of M’

lubasha [3.4K]

Answer:

The answer is "(4, -5)".

Step-by-step explanation:

Please find the complete question in the attached file.

In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is $(x, y) \longrightarrow (y, -x)$

Putting the value in x = 5 and y = 4 then:

$(5, 4) \longrightarrow (4, -5)$
