The situation can be represented in a linear equation using a slope-intercept form as y = 2x - 58
Linear EquationA linear equation is an algebraic equation of the form y = mx + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
Data;
y₁ = 102y₂ = 116x₁ = 80x₂ = 87We can find the slope of the line using
m = y₂ - y₁ / x₂ - x₁
Substituting the values into the equation
m = 116 - 102 / 87 - 80
m = 2
We can find the y-intercept using any point.
y = mx + c
102 = 2(80) + c
102 = 160 + c
c = -58
The equation in slope-intercept form will be y = 2x - 58

Which of the following is equivalent to 17g - 2g?
The equivalent expression to 17g-2g will be (17-2)g.
According to the question,
We have the following expression:
17g-2g
Now, we can simplify this expression easily to find the equivalent expression.
So, our first step will be to take g as a common factor from both the terms. Now, we have the following expression:
(Note that the common factor means that the variable or the number taken as a common factor should be able to divide the terms given in the expression.)
(17-2)g
Now, this can be solved further because 2 can be subtracted from 17 because they both are integers without any variable.
Hence, the correct option is C.

If the store's cost for the incentives was $103.The amount of each incentive that were given away is: Free Rental 5, Box of popcorn 54.
How to find the incentive given?Let Free Rental = r
Let Box of popcorn = p
Total incentives:
r+p=59
r= 59-p Equation 1

Joe is playing a game with a regular die. If the number that turns up is
even, he will gain 5 times the number that comes up. If it is odd, he will
lose 10 times the number that comes
up. He tosses a 3. Express the
results as an integer.
The required solution will be -30 which is expressed as an integer.
To represent this in a general context, we may utilize functions that are referred to in terms of the number tossed.
We know that if the number he gets is an even number, he will get 5 times the number.
As a result, the function for when the integer x is even is f(x) = 5x.
If the number is an odd number, he will lose 10 times the number.
As a result, the function for when the integer x is odd is f(x)=-10x.
Finally, Joe tosses a 3, which is an odd integer, hence the function we will represent is f(x) = - 10x.
⇒ f(3) = -10(3) = -30
Thus, the required solution will be -30 which is expressed as an integer.

The measure of angle KJL from the given figure is 84°.
Given that, 3(m∠LJM)=2(m∠KJL) and m∠KJM=140°.
What is an angle?An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
Here, m∠KJM=m∠LJM+m∠KJL
Now, (m∠LJM)=2/3 (m∠KJL)
140°= 2/3 (m∠KJL) + m∠KJL
⇒ [2(m∠KJL)+3(m∠KJL)]/3 = 140°

Answer:
Step-by-step explanation:
m just means measure. So the question is asking you what is the MEASURE of the ANGLE AEB.
Since angles AEB and CED are vertical angles, you can set the two expressions equal to each other and solve for X.
1) 3x + 54 = 7x - 30
2) 54 = 4x - 30
3) 84 = 4x
4) x = 21
Now that you know x, plug x into the expression for AEB, which is 3x + 54
3(21) + 54 = 117
m∠AEB = 117°
J.D. opened a savings account with $425. After
2 years, the total interest he earned was $10.20.
What was the annual interest rate?
The annual interest rate is 1.2%
The principal amount = $425
The total interest her earned = $10.20
The final amount = 425 + 10.20
= $435.2
Time period = 2 years
The simple interest
A = P(1 + rt)
Where A is the final amount
P is principal amount
r is the interest rate
t is the time period
Substitute the values in the equation
435.2 = 425(1 + r×2)
1 + 2r = 435.2 / 425
Divide the terms
1 + 2r = 1.024
2r = 1.024 - 1
2r = 0.024
r = 0.024/2
Divide the terms
r = 0.012
Then the percentage will be
r = 1.2%
Hence, the annual interest rate is 1.2%
