Y = mx + b
4 = (2)(-3) + b
4 = -6 + b
10 = b
Answer is choice D
Y = 2x + 1
y = 2x - 1
so the 1st one has a y int of 1 and the second one has a y int of -1...so the original line will shift down 2 units
This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
Account balance is not proportional to the number of weeks.
Answer:
5
Step-by-step explanation:
given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.
