Answer: The product of (-4)(-8) is 32. Multiply two negatives makes it positive. So just think of it as 4 times 8. Which is 32.
Answer:
C has a magnitud of 10.4 units and is directed 270° from the positive x-axis
Step-by-step explanation:
As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.
However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.
In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.
Answer:
(0,29)
Step-by-step explanation:
To find the y-intercept, substitute in
0 for x and solve for y OR use a graphing calculator.
Answer:
-18 =x
Step-by-step explanation:
-7 = -1 + x/3
Add 1 to each side
-7+1 = -1+1 + x/3
-6 = x/3
Multiply each side by 3
-6*3 = x/3*3
-18 =x
