Answer:

x = 36

Step-by-step explanation:

The angles 3x - y and 2x + y form a straight angle and are supplementary, so

3x - y + 2x + y = 180

5x = 180 ( divide both sides by 5 )

x = 36

-----------------------------------------------

5y and 3x - y are vertical angles and congruent, hence

5y = 3x - y ( add y to both sides )

6y = 3x ← substitute x = 36

6y = 3 × 36 = 108 ( divide both sides by 6 )

y = 18

Last week’s shipment of plates contained 2 broken plates out of 150. How many could be expected to be broken in next week’s ship

IgorLugansk [536]

3 probably. If 2 plates break out of 150 then you know that dividing 150 with 2 you get 75 and that means that 75 = 1 broken plates and which means that the next weak will be 1 broken plate. 150+75=225.

Line JK passes through points J(–4, –5) and K(–6, 3). If the equation of the line is written in slope-intercept form, y = mx + b

joja [24]

Hello!

First of all we solve for the slope as seen below.

$\frac{3+5}{-6+4} = -\frac{8}{2} = -4$

Our slope is -4.

Now we substitute a point from our equation into slope intercept form, along with the slope. Then we solve for b. We will use (-4,-5)

-5=-4(-4)+b
-5=16+b
b=-21

Our final equation is shown below.

y=-4x-21

I hope this helps!
