The value of the exterior angle next to a triangle is equal to the sum of two angles of the triangle, opposite of the interior angle. In this case: Angle QRT is equal to the sum of angle RTS and angle RST. So if we put that into an equation it will look like this:

9x = 5x + (9 + x)
Now we can solve for x. 
9x = 5x + 9 + x
9x = 6x + 9          (Combine like terms)
9x - 6x = 9            (transpose)
3x = 9
3x/3 = 9/3

x = 3

Factor x^3 -7x^2 -5x+35 by grouping. what is the resulting expression
Anni [7]

Answer:

(x-7) (x^2-5)

Step-by-step explanation:

x^3 -7x^2 -5x+35

Make 2 groups

x^3 -7x^2      -5x+35

Factor x^2 from the first group and -5 from the second group

x^2 (x-7)       -5(x-7)

Now factor (x-7) out

(x-7) (x^2-5)

In a warehouse, a group of identical robots fills orders. In 10 minutes, 5 robots can fill 20 orders. If 8 robots worked at that
Alexxandr [17]

Answer:

192 orders

Step-by-step explanation:

All robots are working simultaneously, so each robot takes 10 minutes to do their orders. They are all identical, so they take an equal amount of time to do each order, meaning 20 ÷ 5 = 4. Each robot takes 10 minutes to do 4 orders.

If there are eight robots working for 60 minutes, each robot can make six times as many orders, compared to when they were working for 10 minutes. 4 x 6 = 24. There are eight robots, so 24 x 8 = 192 orders.

Which is the equation of the line that passes through the points (-4, 3) and (2, -6)?
olga55 [171]

Answer:

B) y=-3/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

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

m=-9/(2+4)

m=-9/6

simplify

m=-3/2

y-y1=m(x-x1)

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

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

y=-3/2x-12/2+3

y=-3/2x-6+3

y=-3/2x-3
