Which of the following situations could be represented by a graph with a y-intercept of -8?
A. Hal bought $8 worth of supplies, then sold x buttons for $3 each. His profit is y dollars.
B. Mr. May has 3 sticks left, and each student needs 8 sticks to make their craft project. There are x students, and they need y sticks in all.
C. Kim ran 3 laps clockwise and 8 laps counterclockwise, for a total of 5 miles of the track. The track is x miles long and she ran a total of y laps.
D. Jian bought 8 packs of paper and sold 3 origami swans. His current profit is -$5. A pack of paper costs x dollars and he sells the swans for y dollars.
The situation given that can be represented by a graph with a y-intercept of -8 is A. Hal bought $8 worth of supplies, then sold x buttons for $3 each. His profit is y dollars.
How to use the y-intercept?The y-intercept is a figure in the linear equation that shows the original number of units before the value of x either started to increase or to decrease and therefore cause a change in x.
The situation where Hal bought $8 worth of supplies would be represented by the y-intercept of -8 because the $8 that Hal bought represents his total profit before he sells anything. That total profit is -8 because Hal has spent -$8 but has not sold anything.

Roxy and Randy are selling pancake breakfast plates to raise money for a class trip.
Roxy is selling plates for $5.00 and has already raised $175. Randy is selling plates for $3.50 and has already raised $250.
Which equation can be used to nd p, the number of plates that Roxy and Randy must sell so that the total amount raised is the same for both Roxy and Randy?
The total amount raised is the same for both Roxy and Randy if they sell 50 Plates.
Let the number of plate = 'p'
Roxy :
Selling price of plates = $5.00
Raised = $175
Total plates sold = 5.00p
Total amount raised = 5.00p + 175 ...eq.(1)
Randy :
Selling price of plates = $3.50
Raised = $250
Total plates sold = 3.50p
Total amount raised = 3.50p + 250 ...eq.(2)
Now we will equate the eq.(1) and eq.(2) to find the same amount raised by both Roxy and Randy ,
5.00p + 175 = 3.50p + 250
5.00p - 3.50p =250 - 175
1.5p = 75
p = 75/1.5
p = 50

For the given equation, the value of d = 30
How to solve an equation?To solve linear equations, utilize the steps that are provided below. Remove parenthesis from either side of the equation and combine similar phrases to make it simpler. To separate the variable term on one side of the equation, use addition or subtraction. To find the variable, use division or multiplication.
Divide both sides of the equation by the coefficient of variable: d-12 = 10÷ 5/9
Divide a fraction by multiplying its reciprocal: d 9 -12=10 x 9/5
Write as a single fraction: d-12 = (10 x 9) / 5
Calculate the product or quotient: d-12= 90 / 5
Reduce fraction to the lowest term by canceling the greatest common factor: d-12 = 18

Determine whether each set of numbers can be the measures of the sides of a triangle. If so, classify the triangle as acute, obtuse, or right. Justify your answer.
16,18,26
Yes, the given set of numbers can be the measures of the sides of a triangle. The triangle is acute.
By the triangle inequality theorem, the sum of the lengths of any two sides should be greater than the length of the third side.
16 + 18 > 26
18 + 26 > 16
26 + 16 > 18
Hence, these set of numbers can be the measures of the sides of a triangle.
According to the Pythagorean Inequality Theorem, a triangle whose sides measure a, b, and c where c is the largest, the triangle can be characterized as:
acute if [tex]a^{2} + b^{2} < c^{2}[/tex]
obtuse if [tex]a^{2} + b^{2} > c^{2}[/tex]
right if [tex]a^{2} + b^{2} = c^{2}[/tex]
∴The longest side is 26.
Hence, a = 16, b = 18 and c = 26;
Consider [tex]a^{2} + b^{2[/tex] :
= [tex]16^{2} + 18^{2}[/tex]
= 580.
Now consider [tex]c^{2}[/tex] :
= [tex]26^{2}[/tex]
= 676.
Thus, [tex]a^{2} + b^{2} < c^{2}[/tex].
Hence, the triangle is acute.

The perimeter of a square is 4 times as
great as the length of any of its sides.
Determine if the perimeter of a square is proportional to its side length. Explain.
Answer:
Perimeter of a square is proportional to side length
Step-by-step explanation:
We have the relation p = 4a, p = perimeter, a = side length
This is the equation for a proportionate relationship of the form y = k.x where y ∝ x , y directly proportional to x => y varies as x varies and always by the same constant
k is known as constant of proportionality
Here k = 4
Let's say the side of square is 1. Then perimeter = 4
If side is increased to 2, then perimeter = 4 x 2 = 8
If side is increased to 3, then perimeter is 4 x 3 = 12
So perimeter increases by a factor of 4 for every unit increase in side length

According to tradition, the "image" of point P is the reflection of point P across the line, which is designated by the term P' (pronounced "P prime").

Which number line best shows how to solve −4 − (−6)?
Answer:
D
Step-by-step explanation:
You want to find the number line that shows the solution to -4 -(-6).
Number line operationsThe first number in the "sum" is -4, so the first arrow on the number line should go from 0 to -4. (All choices show that.)
The second number is -6. Addition of -6 would create an arrow from -4 going 6 units to the left. Subtraction works in the opposite direction, so the subtraction of -6 will show as an arrow from -4 extending 6 units to the right. Only answer choice D shows this.
__
Additional comment
You know the solution is -4 -(-6) = -4 +6 = +2, so the graph showing the solution will have an arrow ending at +2. This eliminates all answer choices except the correct one.
