The correct answer is: The set must have a constant additive rate of change.
Let Y be a data set containing an independent and dependent variable.
The standard form of the equation of a line is given by y = mx + b, where x is an independent variable and y is a dependent variable, m is the slope, and b is the y-intercept.
Now, when m = 1,
y = x + c
When m = 2,
y = 2x + c = x + x + c
When m = 3,
y = 3x + c = x + x + x + c
As a result, the set must change at a constant additive rate.In order to avoid the function changing into an exponential function, which is not linear, the set must not have a constant multiplicative rate of change.As the set of real numbers is the domain of the linear function, the values in the set may be positive or negative.And, the values in the set must be rising.Learn more about data set here:

Answer:
f(1) + g(2) = 7
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=-x^2+2x-3\\g(x)=10-\dfrac{1}{2}x \end{cases}[/tex]
To find f(1), substitute x = 1 into function f(x):
[tex]\begin{aligned}x=1 \implies f(1)& =-(1)^2+2(1)-3\\& = -1+2-3\\&=1-3\\&=-2\end{aligned}[/tex]
To find g(2), substitute x = 2 into function g(x):
[tex]\begin{aligned}x=2 \implies g(2)& =10-\dfrac{1}{2}(2)\\& =10-1\\&=9\end{aligned}[/tex]
Therefore, to evaluate f(1) + g(2), sum the two values found for f(1) and g(2):
[tex]\begin{aligned}\implies f(1)+g(2)&=-2+9\\&=7\end{aligned}[/tex]
As one calculation:
[tex]\begin{aligned}\implies f(1)+g(2)&=-(1)^2+2(1)-3+10-\dfrac{1}{2}(2)\\&=-1+2-3+10-1\\&=1-3+10-1\\&=-2+10-1\\&=8-1\\&=7\end{aligned}[/tex]
How much more will his shirt cost in Fresno than Bakersfield (in dollars)? (Round each to the nearest cent and write your answer as a decimal).
The amount of money more that his shirt cost in Fresno than Bakersfield is $0.145.
How to calculate the value?Given that the amount of shirt is $20. The value of the shirt in Fresno will be:
= Cost + Tax
= $20 + (8.225% × $20)
= $20 + $1.645
= $21.645
The value in Bakersfield will be:
= Cost + Tax
= $20 + (7.5% × $20)
= $20 + $1.5
= $21.5
The difference will be:
= $21.645 - $21.5
= $0.145

Which number is the additive inverse of -10 1/4 ?
10 1/4
-4 1/10
0
4/41
The additive inverse is 10(1/4)
What is additive inverse?By merely switching the integer's sign, you can add the original number and the additive inverse to produce a result equal to 0. The attributes of additive inverse are outlined below based on the negation of the original number. For instance, if the beginning integer is x, the additive inverse of x is -x.
The additive inverse of a number is the one that, when added to, yields zero. Other names for this exact number include sign change, negation, and the opposite (number).
Given -10(1/4)
-10(1/4) + 10(1/4) = 0

Ethan says that the value of 40.7 is 10 times the value of 4.07
The assumption Ethan made was correct
What is Fraction?
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
Ethan said that the result of 10 and 4.07 is 40.7, thus we must verify that his computation is accurate.
In order to do such, we must multiply 10 by 4.07 as illustrated below:
= 10 x 4.07
= 10 x 407/100
= 4070/100
= 40.70
Since the outcome matches Ethan's hypothesis,

Jillian stayed at the samehotel but spent four nights and rented a car for five days from the samecompany. If Connor paid $675 and Jillian paid $875, how much did onenight at the hotel cost?
Solution:
Let x the cost for a night and y the cost to rent a car for a day.
Connor = 3 nights and 4 days = 3x + 4y = 675
Jillian = 4 nights and 5 days = 4x + 5y = 875
3x + 4y = 675 Multiply by 5
4x + 5y = 875 Multiply by 4
we get:
15x + 20y = 3375
16x + 20y = 3500
now, subtracting the two previous equations we obtain:
15x + 20y = 3375

Step-by-step explanation:
This question involves the concept of reading values from graph.
The first 3 questions are basically asking you to find the value of y when x is a certain value.
a) g(7) is asking to find the value of y when x = 7.
So we can see from the graph, when x = 7, y = 4.
b) g(0) is asking to find the value of y when x = 0.
So we can see from the graph, when x = 0, y = 7.
c) g(-5) is asking to find the value of y when x = -5.
So we can see from the graph, when x = -5, y = 6 (Read from the value of 5 on the left side of the graph since x is negative.)
d) This question is asking us to do the opposite compared to the other 3 questions, its asking us to find the value of x when y = 3.
So, we can see from the graph, when y = 3, x = 9.
Joe bought 2 pairs of jeans and 1 shirt for 120 Sam bought 1 pair of jeans and 3 shirts for 135 How much does one shirt cost
Answer:
One shirt costs $80 and a pair of jeans equals $`15.
Step-by-step explanation:
If the shirt would cost $80 and you get 1, the jeans would equal 15. 2 pairs of jeans is 30, leaving $80 for the 1 shirt. You buy 1 pair of jeans, 15, and get 3 shirts for 135, 3 shirts would be 120. 120 + 15= 135. 80 + 15 + 15= 120.
Answer:
One shirt costs 30
Step-by-step explanation:
So, we don't know the prices for 1 shirt & 1 jeans, and we're to find the value of 1 shirt. Let's take it that:
1 shirt costs: x
1 jeans costs: y
Given that two persons in the names of Joe and Sam bought 2 pairs of jeans and 1 shirt for 120 and 1 pair of jeans and 3 shirts for 135 respectively, we can actually see that both persons bought jeans and shirts for different values. With the information, we convert to simultaneous equation.
The first info states that:
[tex]2y + x = 120→equ(i)[/tex]
The second info states that:
[tex]y + 3x = 135→equ(ii)[/tex]
Now, since we are to find the cost of 1 shirt (x), we make y the subject of formula in equation (ii) to solve for x.
[tex]y = 135 - 3x→equ(iii)[/tex]
Replace for the value of y in equation (i)
[tex]2(135 - 3x) + x = 120[/tex]
[tex]270 - 6x + x = 120[/tex]
Take like terms
[tex]-5x = 120 - 270[/tex]
[tex]-5x = -150[/tex]
Divide both sides by -5 to find the value of x
x = -150/ -5
Therefore: x = 30
Replace for the value of x in any of the equations

Doreen Schmidt is a chemist. She needs to prepare 32 ounces of a 9% hydrochloric acid solution. Find the amount of
16% solution and the amount of 8% solution she should mix to get this solution.
how many ounces of the 16% acid solution should be in the mixture?
how many ounces of the 8% acid solution should be in the mixture?
Answer:
See below
Step-by-step explanation:
She needs 32 ounces finshed product
x = 16 % amount amount of acid = .16x
then (32-x) = 8% amount amount of acid = .08(32-x)
final product 9% acid = .09 (32)
.16x + .08 ( 32-x) = .09(32)
solve for x = 16% amount = 4 ounces 8% then is 28 ounces

There is an infinite number of values that are in both the domain and range.
Define domain and range.The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values. The collection of all potential inputs for a function is its domain.

a ferris wheel has a radius of 16 feet. how far will you travel if you go around 5 times ? pi= 22/7
Answer
Total distance travelled = 502.86 feet
Explanation
To know how far one would go, we need to first find the circumference of the ferris wheel. Since it is circular in shape,
Circumference = 2πr
where
π = pi = (22/7)
r = radius of the ferris wheel = 16 feet
Circumference = 2πr
Circumference = 2 × (22/7) × 16
Circumference = 100.57 feet
So, if one now goes round this exactly 5 times,
Total distance travelled = 5 (Circumfernce of the ferris wheel)
Total distance travelled = 5 (100.57)
Total distance travelled = 502.86 feet
Hope this Helps!!!
