The linear equations for cost price and selling price are c = 3x + 35 and y = 5x.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Let Max make x cups of lemonade cup.
According to given conditions,
Cost of 1 cup of lemonade = $3.
Also, Max pay for renters fee = $35.
The cost of x cups of lemonade = 3x
The total cost c = 3x + 35
Since, Max sells lemonade for $5 per cup.
Let the selling price is represented by y,
Then selling price y = 5x

What is the product when x- 5 is multiplied by
2x + 3?
1.) 2x² - 7x - 15
2.) 2x² - 13x - 15
3.) 2x² +13x + 15
4.) 2x² +7x - 15
Answer:
2x² + 7x - 15.
Step-by-step explanation:
The product when x- 5 is multiplied by 2x + 3 is 2x² +7x - 15. To find the product, we need to use the distributive property. This states that for any two expressions, a and b, and a constant, c, we have the following:
c * (a + b) = c * a + c * b
We can use this property to expand the expression (x - 5)(2x + 3) as follows:
(x - 5)(2x + 3) = (x * 2x) + (x * 3) + (-5 * 2x) + (-5 * 3)
= 2x^2 + 3x + (-10x) + (-15)
= 2x^2 + 7x - 15
Therefore, the product of the expression (x - 5)(2x + 3) is 2x^2 + 7x - 15, which matches the answer choice 2x² + 7x - 15.

What are Parallel Lines Cut by Transversal?
Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.
Corresponding angles
When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position
Alternate Interior Angles
Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.
Alternate Exterior Angles
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Consecutive Interior Angles
When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.
Given data ,
From the figure , we can see that
The angles 5 , 6 , 7 and 8 are all on the straight line t
The angles 1 , 2 , 3 and 4 are all on the straight line n
The line m is the transversal line
Now ,
From the theorem of angles on a parallel lines , we get
Alternate angles are equal
So , 2 = 8 and 3 = 5
Now ,
Angle 2 and Angle 8 = Alternate Interior Angles
Angle 3 and Angle 5 = Alternate Exterior Angles
Corresponding angles are equal
So , 1 = 5 and 2 = 6

The equation of the line is y = 0.4x - 793.65 and the minimum wage is $18.35
What is Equation of LineThe equation of a line can be formed with the help of the slope of the line and a point on the line. Let us understand more about the slope of the line and the needed point on the line, to better understand the formation of the equation of a line. The slope of the line is the inclination of the line with the positive x-axis and is expressed as a numeric integer, fraction, or the tangent of the angle it makes with the positive x-axis. The point refers to a point in the coordinate system with the x coordinate and the y coordinate.
a)
Taking two points from the table;
Using 1996 and 1997
The data are; (1996, 4.75), (1997, 5.15)
m = y₂ - y₁ / x₂ - x₁
m = 5.15 - 4.75 / 1997 - 1996
m = 0.4
The slope of the line is 0.4
Using the line equation;
y = mx + c
Taking one point, we can find y-intercept here
5.15 = 0.4(1997) + c
5.15 = 798.8 + c
c = 5.15 - 798.8
c = -793.65
The equation of the line is y = 0.4x - 793.65
b) The minimum wage in 2030
y = 0.4x - 793.65
y = 0.4(2030) - 793.65

  Is it true that 7w + 4 = 5w + 12.
A. Write three more equations that you know are true based on this information.
B. Find the value of 2w.
C. Find the value of w.
Answer:
A. Here are three more equations that are true based on the information you provided:
1. 3w + 2 = 2w + 6
2. 5w - 6 = 4w - 8
3. 7w - 5 = 6w - 7
B. To find the value of 2w, we need to first solve for w in the original equation 7w + 4 = 5w + 12. We can do this by subtracting 5w from both sides of the equation, which gives us 2w + 4 = 12. Then we can subtract 4 from both sides to get 2w = 8. Therefore, the value of 2w is 8.
C. To find the value of w, we can divide both sides of the equation 2w = 8 by 2, which gives us w = 4. Therefore, the value of w is 4.

The probability that A will have more heads than B is 1/2, when A and B are playing a game where a has n + 1 coins, b has n coins, and they each flip all of their coins.
Given, a and b are playing a game where a has n + 1 coins, b has n coins, and they each flip all of their coins.
we have to find the probability that a will have more heads than b.
Now, p1 = "probability that A obtains more heads than B.".
p2 = "probability that B obtains more heads than A.".
p3 = "probability that A obtains as many heads as B.".
Such that p1 + p2 + p3 = 1.
Since, both flips n coins, A wins with the same probability as B.
p1 = p2
Now, A flips and extra coin.
½ of the time it gives tails and doesn't contribute, but ½ of the time is gives heads meaning that A now wins if they before had equal number of heads.
p1+1/2(1 − p1 − p2)=1/2.

Henry has $150.00 to spend on a rental car for 2 days. It costs $39.90
per day plus $0.20 per mile to rent the car. Which inequality represents
how many miles, m, Henry can drive the car?
A. m ≤ 351
B. m ≥ 351
C. m ≤ 550.5
D. m ≥ 550.5
Answer:
The inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality can be derived by first calculating the total cost of renting the car for 2 days at $39.90 per day and $0.20 per mile. This gives us a total cost of $79.80 for the rental plus $0.20 per mile for the number of miles Henry drives. Since Henry has $150.00 to spend, we can set up the following inequality to represent the maximum number of miles he can drive:
150.00 >= 79.80 + 0.20m
We can then solve for m by subtracting 79.80 from both sides of the inequality and dividing both sides by 0.20, which gives us:
m <= 550.5
Therefore, the inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality states that Henry can drive the car for a maximum of 550.5 miles.
