Answer:

1. Because they are Vertically opposite

2. 2 lines that form a straight line and form 180 degrees when added are called a linear pair.

3. Because angle 1 and 2 is a linear pair and forms 180 degrees. The same goes for angles 2 and 3.

4. Because when they are a linear pair and together they form 180 degrees.

5. Angle 1 and 2, angles 2 and 3 are linear pairs. And linear pairs always form 180 degrees. So, they are both equal.

6. Because they are vertically opposite angles.

7. Because they are vertically opposite angles.

For the graphed exponential equation, calculate the average rate of change from x = −4 to x = 4. Possible answer choices being;
Kruka [31]
The rate of change is given by:
[f(a)-f(b)]/[a-b]
thus the rate of change from x=-4 to x=4 will be:
[f(4)-f(-4)]/(4-(-4))
=[-5-0]/[4+4]
=-5/8

Answer: -5/8

1/2 (b - 10) + 2b = 25
Serggg [28]

Answer:

the answer is 12

Step-by-step explanation:

Simplify both sides of the equation.

12(b−10)+2b=25

(12)(b)+(12)(−10)+2b=25(Distribute)

12b+−5+2b=25

(12b+2b)+(−5)=25 (Combine Like Terms)

52b+−5=25

52b−5=25

add 5 to both sides.

52b−5+5=25+5

52b=30

multiply both sides by 2/5.

(25)*(52b)=(25)*(30)

b=12

Select 2 points PLEASE ANSWER THANKS YOU SO MUCH
Xelga [282]

Answer:

1) The graph is as shown at the attached figure.

2) The line passes with (1,-3) and (2,-2)

Step-by-step explanation:

graph the line that passes with (3,-1) and has a y-intercept of -4

y-intercept is the value of y when x = 0

So, the line passes with (0 , -4)

The general form of the line  y = mx + c

Where m is the slope and c is y-intercept

given y-intercept = -4 ⇒ ∴ c = -4

using the other point to find m

So, when x = 3 , y = -1

So,  -1 = 3m - 4

Solve for m

3m = -1 + 4 = 3

m= 3/3 = 1

So, the equation of the line ⇒ <u>y = x - 4</u>

See the attached figure which represents the graph of the line

As shown at the graph the line passes through the points <u>(1,-3) and (2,-2)</u>
