Answer:

Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ 3, 4 ]
f(b) = f(4) = 9 ← value of f(x) when x = 4 , from table
f(a) = f(3) = 3 ← value of f(x) when x = 3 , from table
average rate of change = [tex]\frac{9-3}{4-3}[/tex] = [tex]\frac{6}{1}[/tex] = 6

Ok sooooooo the line is at the y intercept at (0,-50)
And if u choose two points on the graph (solid points) likeeee…. (0,-50) and (20,-30)
Use rise/ run
Soooo u go up two units and right two units soooo 2/2!!! Simplified thats what?? Thats 1!!
And so.
Y=mx+b
Plug in a few numbers….
Y=1x-50
Aaaaand the slope is moooving up (how do I know??) because from the start which is (0,-50) it goes up. So that’s why the 1 is positive. It’d be negative if it’s going the other way.
Sorry if that made no sense but moral of the story, the answer is y=1x-50

with (x₁, y₁ ) = (- 5, 8 ) and (x₂, y₂ ) = (4, 6 )

Aura built a scale model of a building using a scale in which 4 inches represents 60 feet. The height of the building is 420 feet.
What is the height of the scale model in inches?
Answers
Answer:
28 inches
Step-by-step explanation:
We're told that each 60 ft is represented by 4 inches of model. 420 feet is 7 times 60 feet, so the model will be 7 times 4 inches.
The height of the scale model is 28 inches.

Suppose you have a five dollar off coupon at a fabric store you buy a fabric that cost $10 per yard
1.)right in equation that models the total number of money, y, that you can buy x yards of fabric
2.) if you bought 9 yards of fabric how much will you pay
3.) if you paid $47.50 how many yards of fabric did you purchase
Answers
1.) 10x-5=y
2.) $85
3.) 5.25 yards of fabric.
Step-by-step explanation:1.) To write an equation for this problem, we need to figure out what every value means:
the variable x, represents the amount of yards of fabric you can buy
the variable y, represents the total amount of money after you found out (x) or the amount of yards of fabric.
1 yard of fabric equals $10, and we have a $5 coupon (-5)
Our equation is:
10x-5=y
This equation represents the relationship between the total cost of fabric, and the amount that you can buy.
2. In order to solve this problem we need to use our equation, one value is given which is 9.
9 represents x, the amount of yards of fabric.
Substitute 9 into x:
10(9)-5=y
Solve:90-5=y
85=y
85 represents the cost of 9 yards of fabric, including the $5 coupon.
3.) This problem is similar to #2, although it's flipped.
The value given is $47.50, which represents (y), the total amount of money after (x) was found out.
But, we need to figure out (x).
Substitute $47.50 into (y):
10(x)-5=$47.50
Next, we need to figure out x by solving the opposite.
Adding the coupon to our answer can represent 10(x).
$47.50+5=52.50
10(x)=52.50
Lastly, divide both sides of the equation by 10.
10(x) / 10=52.50 /10
x=5.25
5.25 represents the amount of yards of fabric purchased if you paid $47.50.

Step-by-step explanation:
angle A and angle B are complementary angles. If m angle A = (4x – 28)° And angle B = (4x - 8)°, then find the measure of A.
Answers
Complementary angles have a submission of 90 degrees thus :
[tex]angle \: \: A + angle \: \: B = 90°[/tex]
[tex](4x - 28)° + (4x - 8)° = 90°[/tex]
[tex]4x + 4x - 28 - 8 = 90[/tex]
Collect like terms
[tex]8x - 36 = 90[/tex]
Add both sides 36
[tex]8x - 36 + 36 = 90 + 36[/tex]
[tex]8x = 126[/tex]
Divide both sides by 8
[tex] \frac{8x}{8} = \frac{126}{8} \\ [/tex]
[tex]x = 15.75[/tex]
_____________________________________________
Now let's find the measure of A :
[tex]A = 4x - 28[/tex]
[tex]A = 4 \times (15.75) - 28[/tex]
[tex]A = 63 - 28[/tex]
[tex]A = 35°[/tex]
And we're done...

Answer:
If your due dates are at least by the end of the week, I recommend doing straight work for 30 minutes, then rewarding yourself. Repeat this for as long as you want but don't do so much that you weren't able to do anything socially for the whole day. If your due dates are already passed or if they are coming up really soon, I recommend putting on whatever music you like to listen to, but nothing to upbeat. Put on some calm music with a rain sound effects video in the background, and just keep working until you kind of dose off from reality and just get in the zone. A long answer, but it really helps.
Forgot to mention; if you ever get stressed out, either do something else to calm down, or use that stress to your advantage and do a ton of work because of it.

2 (x + 4) = 2 (-8 - x) - 2x
Answers
Answer:
x = -4
Step-by-step explanation:
Simplifying
2[x + 4] = 2[-8 + -1x] + -2x
Reorder the terms:
2[4 + x] = 2[-8 + -1x] + -2x
[4 * 2 + x * 2] = 2[-8 + -1x] + -2x
[8 + 2x] = 2[-8 + -1x] + -2x
8 + 2x = [-8 * 2 + -1x * 2] + -2x
8 + 2x = [-16 + -2x] + -2x
Combine like terms: -2x + -2x = -4x
8 + 2x = -16 + -4x
Solving
8 + 2x = -16 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
8 + 2x + 4x = -16 + -4x + 4x
Combine like terms: 2x + 4x = 6x
8 + 6x = -16 + -4x + 4x
Combine like terms: -4x + 4x = 0
8 + 6x = -16 + 0
8 + 6x = -16
Add '-8' to each side of the equation.
8 + -8 + 6x = -16 + -8
Combine like terms: 8 + -8 = 0
0 + 6x = -16 + -8
6x = -16 + -8
Combine like terms: -16 + -8 = -24
6x = -24
Divide each side by '6'.
x = -4
Simplifying
x = -4
2( x + 4) = 2 (-8 -x) -2x
Use the distributive property to multiply 2 by x + 4.
2x + 8 = 2 (-8 -x) - 2x
Use the distributive property to multiply 2 by -8 -x.
2x + 8 = -16 -2x - 2x
Combine -2x and 2x to get -4x.
2x + 8 = -16 - 4x
Add 4x to both sides.
2x + 8 + 4x = -16
Combine 2x and 4x to get 6x.
6x + 8 = -16
Subtract 8 from both sides.
6x = -16 - 8
Subtract 8 from -16 to get -24.
6x = -24
Divide both sides from 6.
x = [tex]\frac{-24}{6}[/tex]
Divide by -24 by 6 to get -4.
x = -4.
