The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.
(-3 - 1) / (-2 - 0)
(-4) / (-2)
2
The rate of change of this line is 2.
Hope this helps!! :)
Answer: the rate of change is 2

Your business is looking into three contracting firms. Based on previous research, there is a
75% chance that company 1 will earn you $40,000. There is a 45% chance that company 2
will earn you $60,000. Company 3 has a 30%chance of earning you $80,000. It costs $20,000 to draw up legal paperwork for each company. How much profit or loss would you expect
after this deal is done if you sign with all 3 companies?
$21,000 profit
$21,000 loss
$81,000 profit
$81,000 loss

Step-by-step explanation:
find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits
Answer:
2133120
Step-by-step explanation:
using 6 given digits, lets create a 4 digit number:
to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.
6*5*4*3 = 360
with no repeats, 360 numbers can be formed.
this means that each number will occur 60 times each (360/6 digits)
so to find the sum:
60*(2+4+5+6+7+8) = 1920
but, we have one more thing:
In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:
1920(1000+100+10+1) = 1920*1111 = 2133120
Solve:
1 < ( x + 5.5 ) / 2

Also does X have to be on the Left side always?
Answer:
x > -3.4
Step-by-step explanation:
1 < (x + 5.5) / 2
first multiply each side by 2
2 < x + 5.5
Then subtract 5.5 from each side
-3.4 < x
x has to be on the left so you switch the hole equation around to get
x > -3.4
The population of insects in an experiment has
been increasing by 9% each week. If there were 16

The value of time period for the equation is 8.
What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
The population of insects is increasing by 9% each week = 0.09
At the beginning of the experiment, number of insects = 16
Number of insects increased per week
⇒ [tex]16+16(0.09)[/tex]
Let the time period be x.
Number of insects increased after 8 weeks can be found by the equation,
[tex]Future Amount = 16 (1 + 0.09)^{x}[/tex]
⇒ [tex]Future Amount = 16 (1 + 0.09)^{8}[/tex]
Hence we can conclude that the value of time period for the equation is 8.

Answer:
54
Step-by-step explanation:
7 in-state to 2 out-of-state
The sum of 7 and 2 is 9.
For every 9 students, 2 are out of state.
This is the proportion:
2 out-of-state is to 9 total as x out-of-state is to 243 total
2/9 = x/243
9x = 2 * 243

The fraction 15 is the same as 15 divided by ___
Answer:
If its just 15 then its 1
Step-by-step explanation:
Because 15 divided by 1 is 15 which is the fraction.
Answer:
Below,...!
Step-by-step explanation:
15 is not a fraction as is you can put any number over a one and that whole number immediately becomes a fraction:
[tex]\frac{7}{1} or \frac{43}{1} or \frac{987}{1} or \frac{1}{1} or \frac{15}{1}[/tex]
15/1 is your fraction so 15/1 divided into 15 equals 1
[tex]\frac{15}{1} / 15 = 1/1 = 1[/tex]

Robin works as a customer service representative. She knows that the
amount in dollars of her yearly bonus is represented by the expression - 1.25x + 651, where x is the
number of complaints customers had about her during the year. To find her bonus if she gets 12
complaints, she substitutes 12 for x. What should be her next step? What would her bonus be?
Answer:
multiply -1.25 x 12
Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15
now -15 +651= 636

Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.
Answer: A verticle line does not have a slope.
Step-by-step explanation: Slope is the rate of change of y for each change in x. y = 2x is a line with slope of 2. Each time x is incremented by 1, y will increase by twice (2x) that amount. There is no slope to a verticle line, unless you want to call it infinite. The value of y is not defined by x.

BRAINLIEST TO WHO EVER ANSWERS
Answer:
See below
Step-by-step explanation:
f(x) = -2x + 2
Put x = 1
f(1) = -2(1) + 2
f(1) = -2 + 2
f(1) = 0
Put x = 0
f(0) = -2(0) + 2
f(0) = 2
Put x = -1
f(-1) = -2(-1) + 2
f(-1) = +2 + 2
f(-1) = 4
Put x = 2
f(2) = -2(2) + 2
f(2) = -4 + 2
f(2) = -2

Answer:
[tex]\cfrac{7}{6}[/tex]
Step-by-step explanation:
[tex]\cfrac{7}{8} \div \cfrac{3}{4}[/tex]
Divide 7/8 by 3/4 by multiplying 7/8 by the reciprocal of 3/4:
[tex]\cfrac{7}{8}\times[/tex] [tex]\dbinom{4}{3}[/tex]
Now, multiply 7/8 times 4/3 by multiplying numerator times numerator and denominator times denominator:

Choose the correct description of each system of equations.
3x + y = 3
x - 2y = 4
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
Given the system of equation expressed as:
3x + y = 3
x - 2y = 4
Solve simultaneosly;
3x + y = 3 ............. 1 * 1
x - 2y = 4 ...............2 * 3
_________________________
3x + y = 3
3x - 6y = 12
Subtract
y-(6y) = 3 - 12
7y = -9
y = -9/7
Substitute y = -9/7 into the equation to get x
x - 2y = 4
x - 2(-9/7) = 4
x + 18/7 = 4
x = 4 - 18/7
x = 3/7
Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.
