Answer:

QPR = 30 degrees

You have to find the measure of angle QPR.

Solve:

40 = 8x + 7 + 9x + 16

Add like terms

40 = 17x + 23

Solve

40 - 23 = 17x + 23 - 23

17 = 17x\\\frac{17}{17} = \frac{17}{17}x\\1 = x

Plug in x to solve for the angle measure of QPR

9(1) + 16 =\\9 + 16 =\\25

The angle measure of QPR is 25°

PLZ do this!!! I will give brainliest to anyone who does them all right. I need this done at 3:30 (it 2:44 right now)! No fake a

Answer:

A: y=1/3x+5

B: y=-2x+9

C: y=-3

D:y=2x+9

E: y=-10x+80

F:y=x-2

#1 rodney's error for

y=30x+10 is that he started off at 30 but he had to start off at 10 so it starts at (0,10) (1,40) (2,70) and keep going on by adding one to the x value and 30 to the y value

#2 rodneys error for

y=-1/2x+5 is that he went up by 1/2 instead of going down. it's a negative 1/2 so he had to go down

#3 Rodneys error for

y=x-2 is that he didn't start at (0.-2)

I'm not sure about the last picture but i think that it's

Find sin theta if cot theta =-4 and cos theta < 0
asambeis [7]
Imagine the unit circle. The cot(theta) is a line from (0,1) to (-4,1). Imagine it is part of a triangle with the origin (draw it!).

Then the hypotenuse length is √(1+4²) = √17.

The sine rule says that sin(90)/√17 must equal sin(theta)/4, and sin(90)=1, so

sin(\theta) = \frac4{\sqrt{17}}

What is the equation of the line on the graph with points (-2,2) and (-2,-3)
nika2105 [10]

Answer:

x=-2

Step-by-step explanation:

Given points are (-2,2) and (-2,-3).

Now we need to find equation of the line passing through the given points.

So let's begin by finding slope

m=\frac{\left(y_2-y_1\right)}{\left(x_2-x_1\right)}=\frac{\left(-3-2\right)}{\left(-2-\left(-2\right)\right)}=\frac{\left(-5\right)}{\left(-2+2\right)}=-\frac{5}{0}

which is undefined. That means graph of the line must be vertical as you can see that in given points, x-value is not changing.

Equation of vertical line is given by x=k where k is the fixed value of x-coordinate.

x-coordinate is -2 in given points.

Hence final equation is x=-2.

8g+10=35 + 3g math 1
lilavasa [31]

Answer:

g= 5

Step-by-step explanation:

8g+10 = 35 + 3g

-3g                -3g

5g+10=35

    -10  -10

5g= 25

now divide 5 from both sides

5g/5= 25/5

g= 5
