Answer:
5x - 2y = 30
x + y = 35
Step-by-step explanation:
Number of correct answers = x
Number of incorrect answers = y
Points won per correct answer = 5
Points lost per incorrect answer = 2
If Reggie received 30 points :
Required equation :
(points won per correct answer * number of correct answers) + (points lost per incorrect answer * number of incorrect answers)
5x + (-2y) = 30
5x - 2y = 30
Equation showing that Reggie answer all 35 questions :
Number of correct answers + number of incorrect answers = 35
x + y = 35
How many groups were there
Solve this equation:
300+5x=450+2x
3x = 150
x = 50
so the answer is 50 books
the answer would be -21 because you would have to multiply the 24 by -7 because it is dividing on the other side. and then you would have to divide the number you get by 8
so basically, it will look like this step by step:
-7/8x=24
8x=24*-7
8x=-168
x=-168/8
x= -21
Hello!
Find the slope using the slope formula:
m = (y2 - y1) / (x2 - x1)
Plug in the points (-2, 8) and (0, 6) to solve:
m = (6 - 8) / (0 - (-2))
m = -2 / 2
m = -1
The y-intercept of the function is the y-value when x = 0.
According to the table, at x = 0, y = 6. Therefore, the y-intercept is (0, 6).
The correct answer is B.
