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:
C
Step-by-step explanation:
Got it right
Answer:
Yes
Step-by-step explanation:
a function would be a constant negative and a positive relationship, which is present in this picture.
Answer:
x = 
- a
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2T = n(a + x)d
Since n and d are both multipliers, divide both sides by nd
= a + x
Isolate x by subtracting a from both sides, hence
x = - a
