Find the slope of (5,4),(7,4)
2 answers:
Hello!
To find the slope, we use the following formula:
m=
m=
Keep in mind that if the y-coordinates are the same, then the slope is 0.
That's because if the y-coordinates are the same, then the line is horizontal and the rise (how many units we rise up) is 0 units.
Therefore, the slope is: 0.
Hope this helps you!

Answer:
$2500 at 8%.
$2900 st 5%.
Step-by-step explanation:
Let x be the amount invested at rate of 8% and y be the amount invested at the rate of 5%.
We have been given that Heather has divided $5400 between two investments. We can represent this information as:
The return on her investment is $345.
Earnings from the investment at 8% will be 8% of x.
Earnings from the investment at 5% will be 5% of y.
We will use substitution method to solve our system of equations. From equation (1) we will get,
Substituting this value in equation (2) we will get,
Therefore, Heather has invested an amount of $2900 at 5%.
Let us substitute y=2900 in equation (1) to solve for x.
Therefore, Heather has invested an amount of $2500 at 8%.
The experimental probability of the arrow stopping on Section 2 will be . is the ratio of the favorable event to the total number of events.
Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.
No of arrows given in the different section ;
Section 1=18
Section 2=30
Section 3=32
The probability that the arrow stopping on Section 2 is found as;
Hence, the experimental probability of the arrow stopping on Section 2 will be .
