Answer:

x=4,y=3

Step-by-step explanation:

x=19-5y if we transpose equation 2 for x.

Plug that into equation 1

4(19-5y)+3y=25

76-20y+3y=25

76-25=17y

51=17y

y=3

Plug y=3 into equation 2

x+5(3)=19

x=19-15=4

For the parallelogram, if m<2+5x-28 abd m<4=3x-10, find m< 3. ...?
slava [35]
<span>Opposite angles of a parallelogram are equal, so: 


5x - 28 = 3x - 10 

2x = 18 

x = 9 


Plug x = 9 into the equations 

m angle 2 = 5x - 28 = 5 * 9 - 28 = 17 

m angle 4 = 3x - 10 = 3 * 9 - 10 = 17 


The sum of all angles in a parallelogram is 360, 

and we know: m angle 1 = m angle 3, so: 

m angle 1 + m angle 2 + m angle 3 + m angle 4 = 360 

m angle 3 + 17 + m angle 3 + 17 = 360 

2 * (m angle 3) = 360 - 17 - 17 = 326 


m angle 3 = 163</span>

Pleaseee help me asap
Hatshy [7]

Answer:

The unit rate\frac{4}{1} of the graph is 4, the slope of the graph is 4, and the comparison between answers is that they are equal.

Step-by-step explanation:

For every increase of 1 in the X value of the graph, the Y value increases by 4, so the slope would be \frac{4}{1} or 4.

On the graph below, draw any line with a slope of *positive* 2 and draw any line with a slope of *negative* 2.
Elenna [48]

Refer to the image for the graph of the lines.

The common form of the equation of a line is y = mx + c, where m is the slope of the line and c is a constant.

We need to draw any line with a slope m = 2, and

another line with a slope m = -2.

Disclaimer: Let us assume that the constant c = 0.

Then the equation to the line with a slope of "positive" 2 is given by

y = 2x

Then the equation to the line with a slope of "negative" 2 is given by

y = -2x

Refer to the attached image for the graph of the lines with the slope of "positive" 2 and "negative" 2.

f: green line indicates a line with a slope of "positive" 2.

g: blue line indicates a line with a slope of "negative" 2.
