find the equation of the linear function represented by the table below in slope-intercept form. picture of table is below
Answer:
[tex] y = 3x + 2 [/tex]
Step-by-step explanation:
The equation of a linear function in slope-intercept form is: y = mx + b, where, m = slope, and b = y-intercept.
Find slope (m) of the linear function by using any two points, say (3, 11) and (7, 23):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 11}{7 - 3} = \frac{12}{4} = 3 [/tex]
To find the y-intercept (b), substitute the value of the corrdinate pair of any of the points represented on the table, and the value of the slope (m) into [tex] y = mx + b [/tex].
Substituting, x = -1, y = -1, m = 3.
[tex] y = mx + b [/tex]
[tex] -1 = 3(-1) + b [/tex]
[tex] -1 = -3 + b [/tex]
Add 3 to both sides
[tex] -1 + 3 = b [/tex]
[tex] 2 = b [/tex]
[tex] b = 2 [/tex]
Substitute m = 3, and b = 2 into the equation of the linear function in slope-intercept form:
[tex] y = mx + b [/tex]
[tex] y = 3x + 2 [/tex]

Solve using substitution y=3x+2, y=7x-6
Answer:
x=2, y=8 or (2, 8)
Step-by-step explanation:
y=3x+2
y=7x-6
substitute y=7x-6 into y=3x+2
7x-6=3x+2
4x=8
x=2
then plug 2 into either one
y=7(2)-6
y=8
Check answers
8=3(2) + 2 | correct
8 =7(2)-6 | correct
Joe's employer will reimburse him $0.07 per mile driven. If Joe drives 179.53 miles on a business trip, what is his mileage reimbursement? Round your answer to the nearest cent.
Answer:
$12.27
Step-by-step explanation:
.07 times 179.53 is 12.5671 so rounded to 12.27
The mileage reimbursement for Joe is: $12.27 to the nearest cent.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have been given that Joe's employer will reimburse him $0.07 per mile driven.
If the employer reimburses $0.07 per mile driven, we just need to multiply $0.07 by the number of miles that Joe drives.
So, the mileage reimbursement for Joe is:
0.07 x 179.53 = 12.5671
so rounded to 12.27
Therefore, The mileage reimbursement for Joe is: $12.27 to the nearest cent.
