You multiply all of them together and then dived by 100 and that's your answer
Answer: C
Step-by-step explanation: The standard equation is Ax + By = C
To solve for this, first solve for the slope: y2 - y1 / x2 - x1
0 - 5 / 4 - 0 = -5 / 4
Plug the slope and ordered pair of (0, 5) into the equation y - y1 = m(x - x1)
y - 5 = -5/4(x - 0)
Add 5 to both sides: y = -5/4x + 5
Subtract y and 5: -5 = -5/4x - y
Multiply the entire equation by 4: -20 = -5x - 4y
(or multiply entire equation by -4 to get 20 = 5x + 4y)
Answer:
-1
Step-by-step explanation:
3 • 7 = 21
Find two factors of 21 whose sum equals the coefficient of the middle term, which is -1 .
-21 + -1 = -22
-1 + -21 = -22
1 + 21 = 22
21 + 1 = 22
