1. The coefficient of x is the constant of variation. It is 40.
2. -12 = -2*6 . . . . . you know this because you know your times tables
.. f(x) = -2x
Answer:
7y-3x-8z
Step-by-step explanation:
(3y+4y)+(2x-5x)-8z
7y+(2x-5x)-8z
7y-3x-8z
Answer:
Step-by-step explanation:
- The length of the segment JM is 25 units.
- The segment JL is between 0 and 12, so is 12 units.
- The segment KL is between 5 and 12, so is 7 units.
<u>The probabilities for each point:</u>
- P(point on JL) = 12/25
- P(point not on KL) = 1 - 7/25 = 18/25
<u>Required probability:</u>
- P = 12/25*18/25 = 216/625
Correct choice is D
Insert the point, (5,-2) with the slope of the line to figure out the equation. You can either use point-slope form, or plug it for for slope-intercept form.
Slope-intercept form:
-2 = -2(5) + b
-2 = -10 + b
Add 10 on both sides
8 = b
Thus,
y = -2x + 8
Answer is B
