Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
Dividing both sides by 0.45
Therefore,
There were 120 questions on the test.
Answer:
y = -1 + 1
Step-by-step explanation:
The line (a) passing through point (3, -4) is perpendicular to line (b) whose equation is; y = -2 + x
The slope of line (b) =
For perpendicular lines, the product of their slopes = -1
So line (a) has a slope of: -1 ÷ = -
Taking another point (x,y) on line (a);
Slope = change in y ÷ change in x
= -
y + 4 = (x - 3)
y = -x + 5 - 4
y = -x + 1
Finally,
y = -1 + 1
