When the 2 graphs are the same. It'll be infinitely many solutions.
System Equations are to find the intercepts of graphs so just think that when 2 graphs are same, that means they both intercept each others infinitely.
So the answer is clearly C.
Answer:
Step-by-step explanation:
Let
x -----> the number of ice cream cones sold 5 years ago
Remember that
we know that
Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.
so
The linear equation that represent this problem is
Solve for x
Divide by 1.3 both sides
Kevin installed a certain brand of automatic garage door opener that utilizes a transmitter control with four independent switches, each one set on or off. The receiver (wired to the door) must be set with the same pattern as the transmitter. If six neighbors with the same type of opener set their switches independently.<u>The probability of at least one pair of neighbors using the same settings is 0.65633</u>
Step-by-step explanation:
<u>Step 1</u>
In the question it is given that
Automatic garage door opener utilizes a transmitter control with four independent switches
<u>So .the number of Combinations possible with the Transmitters </u>=
2*2*2*2= 16
<u>
Step 2</u>
Probability of at least one pair of neighbors using the same settings = 1- Probability of All Neighbors using different settings.
= 1- 16*15*14*13*12*11/(16^6)
<u>
Step 3</u>
Probability of at least one pair of neighbors using the same settings=
= 1- 0.343666
<u>
Step 4</u>
<u>So the probability of at least </u>one pair of neighbors using the same settings
is 0.65633
45.5X-5
Step-by-step explanation:
you simply add the 2 "x" digits together, in this case 2.5x and 43x. 43+2.5=45.5X. then subtract the five, but since they are not alike (or it doesnt have an c) you domt subtract from the 43.
