Hello from MrBillDoesMath!
Answer:
(3,6) is not a point of intersection of the lines.
Discussion:
Let's check if the supposed point of intersection, (3,6), is on both lines. Start by substituting x = 3 and y = 6 in the equation y = 4x -2. This gives
y = 4x - 2
6 = 4(3) - 2 = 12 -2 = 10
6 does not equal ten so the supposed point of intersection doesn't even lie on one of the lines! Hence (3,6) is not a point of intersection of the lines.
Thank you,
MrB
Try this options:
a. total - 6 digits, '6' - 1 digit, then probability of rolling a '6' is 1/6;
b. total - 6 digits, '6' - 1 digit, then probability of rolling 1,2,3,4,5 is 5/6;
c. if probability of rolling a '6' is p and not rolling a '6' is q, then p+q=1;
d. if expected probability of one rolling a '6' is 1/6, then numbers of times of rolling a '6' during 120 times is 120/6=20 times.
Answer:
x = 4
Step-by-step explanation:
1. Find the degree measure of the unknown angle:
90-68 = 22 degrees
2. Find the appropriate slope ratio:
22 degrees = 2/5
3. Redraw the right triangle on a coordinate plane with the right angle on the origin if you have trouble visualizing the next step.
4. 2/5 = rise/run = x/10
2/5 = x/10
x = 4
