Hello,
let x the first angle

5x the second
2/3 x the third

x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18

27+135+18=180

Find the rate of change for a linear function that passes through the points (-5, 1) and (1, 10).
Lyrx [107]
The slope of the function for rise/run would be 3/2, this is because;
The function passes through (-5,1) and (1,10). Lets find the change on the y and x axis.
For the x axis;
-5 to 1.
That is a change of positive 6.
-5+6=1
For the y axis;
1 to 10.
That is a change of positive 9.
1+9=10
For the slope we must put rise (change in y axis) over run (change in x axis) to get 3/2 when simplified from 9/6.
For every 2 units of rise in the x axis the y axis rises by 3.

Pls write the steps u did​
frez [133]

When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.

Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.

See the drawing attached below.

Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:

m<DIE + m<HID = 18

40 + m<HID = 180

m<HID = 140

Similarly:

m<BHC + m<CHI = 180

130 + m<CHI = 180

m<CHI = 50

Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:

m<DIE = m<GIH = 40

m<GIE = m<HID = 140

m<CHI = m<AHB = 50

m<BHC = m<AHI = 130

What do they represent?
andrey2020 [161]

Answer:

A

Step-by-step explanation:

If you convert the first equation to y=mx+b form, it will be the same as the second equation.

6x - 15y = 15

-15y = -6x + 15

y = \frac{2}{5}x -1

Because the 2 equations are the same now, they are the same line.
