Slope is equal to the change in y over the change in x or rise over run:
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise):
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope:
m=5−(−8)/8−(4)
Simplify:
m=13/4
Substitute the value of m into the slope-intercept form of the equation, y = m x + b :
y=(13/4)x+b
Substitute the value of x into the slope-intercept form of the equation, y = m x + b .
y = ( 13/ 4 ) ⋅ ( 4 ) + b
Substitute the value of y into the slope-intercept form of the equation, y = m x + b .
− 8 = ( 13/ 4 ) ⋅ ( 4 ) + b
Rewrite the equation as ( 13 4 ) ⋅ ( 4 ) + b = − 8 .
( 13/ 4 ) ⋅ ( 4 ) + b = − 8
Cancel the common factor.
13/ 4 ⋅ 4 + b = − 8
Rewrite the expression.
13 + b = − 8
Move all terms not containing b to the right side of the equation.
b = − 21
The values of the slope and y-intercept are m = 13 4 and b = − 21 .
m = 13 4
b = − 21

Mike owes his friend $4. Each day, Mike earns $2.
(a) Write an equation that describes the situation in slope-intercept form and explain what the x- and yvalues represent.
(b) Graph the situation on a coordinate plane assuming the domain is all real numbers.
(c) What does the x-intercept mean? What does the y-intercept mean?
(d) Does the situation involve direct variation or not? If it does, justify your answer. If it does not, describe
how the situation would need to change in order for y to directly vary with x. Then, write a direct

–2x + 3x – 5 = 6 – 21
70 = 7m
4 – 14 = 5x
2y + 3y = 4 – 6 – 13
Answer:
Step-by-step explanation:
-2 = y + 5
- y -2 = 5
- y = 5 + 2
- y = 7
y = -7
-2x + 3x – 5 = 6 – 21
x – 5 = 6 – 21

x = -15 + 5
x = -10

What is the vertex of the graph of the function f(x) = x2 + 6x + 9?
0 A. (-3,0)
B. (0, -3)
C. (0, 3)
O D. (3, 0)
The vertex of the given quadratic function is (-3, 0).
What is vertex form of a quadratic equation?The vertex form of a quadratic equation or function is [tex]f(x)=a(x-h)^{2} +k[/tex].
Where,
(h, k ) is the vertex
And, a is constant.
According to the given question
We have a quadratic function
[tex]f(x) = x^{2} + 6x + 9[/tex]
The above function can be written as
[tex]f(x) = x^{2} +2(3x) +9[/tex]
⇒[tex]f(x) = x^{2} + 2(3x) + (3^{2}) -(3)^{2} + 9[/tex]
⇒[tex]f(x) = (x+3)^{2} -9+9[/tex]
⇒[tex]f(x) = (x+3)^{2} + 0[/tex]
Comparing the above equation with the standard vertex form of quadratic function we get
h = -3 and k = 0
Hence, the vertex of the given quadratic function is (-3, 0).
Thus, option A is correct.

A local sporting goods store is planning to hire up to 24 temporary employees for its annual Black Friday Sale. Experienced workers (x) will be paid $20 per hour and produce 1.5 times the profit that an inexperienced worker produces. Inexperienced workers (y) get hired at $15 per hour. The store can pay up to $400 per hour for the temporary employees. How many of each type of worker can be hired to maximize profit?
Answer:
8 experienced workers and 16 inexperienced workers
Step-by-step explanation:
Let x represent the number of experienced workers, y represent the number of inexperienced workers.
The store can hire up to 24 temporary employees, hence:
x + y ≤ 24
The store can pay up to $400 per hour, hence:
20x + 15y ≤ 400
Also, x, y > 0
The solution to the above problem is at (8, 16). Hence x = 8 and y = 16.
The profit of an experienced worker is 1.5 times the profit that an inexperienced worker. hence:
Profit = 1.5x + y
Profit = 1.5(8) + 16
Profit = 12 + 16 = 28

If 15% of x is 42, what is x?
The required whole value of x is 280 if 15% of x is 42.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
To determine the value of x, we can set up the equation: (15/100)x = 42.
This equation states that 15% of x is equal to 42.
To solve for x, we can divide both sides of the equation by (15/100) to get:
x = (100/15) × 42
x = 280
So x = 280.
This means that if 15% of x is 42, then the whole value of x is 280.

A box contains 6 blue pens and 10 red pens. What is the ratio of red pens to total pens as a fraction
Answer: 5/8
Step-by-step explanation: The ratio is 10:16 because total of 16 pens and 10 being red.
The ratio of red pens to total pens as a fraction is 5/8.
What is Ratio?A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other
The ratio of red pens to total pens can be expressed as a fraction. To find this fraction, we need to divide the number of red pens by the total number of pens.
The total number of pens in the box is 6 blue pens + 10 red pens = 16 pens
So, the fraction representing the ratio of red pens to total pens is:
10/16
It can be simplified by dividing both the numerator and denominator by 2, to get
5/8
So the ratio of red pens to total pens as a fraction is 5/8. This means that out of every 8 pens, 5 are red.
