Answer:
y = 3
Step-by-step explanation:
find out the slope
m = (3-3)/(4-7)
m = 0
so the line is horizontal
passing through the point (x,3)
x can be any value
so the equation is
y = 3
Answer:
There is a total 50 questions.
Step-by-step explanation:
Let x = total questions in the exam
Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.
With this information we can write:
(Given that the student made 9 mistakes)
(divide 18% on both sides)
∴ There was a total of 50 questions in the examination.
Answer:
See below
Step-by-step explanation:
Domain: set of x values
Range: set of y values
Function: no two x values are the same
Line 1:
Domain: {3, 4, 5}
Range: {1, 2, 3, 4}
Function: no since there are two points with x-coordinate 3
Line 2:
Domain: {-1, -2, 1, 2}
Range: {1, 3}
Function: yes since all x-coordinates are different
Line 3:
Domain: {-2, -1, 0, 1, 2}
Range: {0, 1, 4}
Function: yes since all x-coordinates are different
Answer:
Total calories in 8 cup = 928 calories
Step-by-step explanation:
Given:
