Answer:
B. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of a linear equation. then the ordered pair must satisfy the linear equation
In this problem we have
<u>verify each case</u>
case A) 
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case A) is not a solution
case B)
substitute the value of x and the value of y in the linear equation and then compare
-----> is true
therefore
The ordered pair case B) is a solution
case C) 
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case C) is not a solution
case D) 
substitute the value of x and the value of y in the linear equation and then compare
-----> is not true
therefore
The ordered pair case D) is not a solution
425 / 50 = 8,5
There you go.
There is an error in the equation provided. Looking at other similar question such as this, I think the equation related to x and y should be 90x + 1600 = y
Answer:
a) 90
b) 1600
Step-by-step explanation:
The equation 90x + 1600 = y is an equation of a straight line in the form y = mc + c
Adjusting the equation to the general form we get
y = 90x + 1600
m = 90
c = 1600
a) the change in Mary's total pay for each copy she sells in this case is referring to the change of y to the change of x.
In other word, it is the slope of the function.
m = 90
b) if Mary didn't sell any copies, the value of x will be 0.
In graph of a straight line, the value when x= 0 is at the value of y-intercept,
c = 1600
See the attached picture:
37.1 miles
Since the driver drove 1 day I subtracted $25 from his bill leaving you with $4.46 change
then divided the change by 0.12 to find the miles Millie drove which will leave you to 37.16667
