(-15,-6), (8,3) Find the slope of the line through each pair of points?
Answers
Slope is equal to the change in
y
over the change in
x
, or rise over run.
m = change in y / change in x
The change in
x
is equal to the difference in x-coordinates (also called run), and the change in
y
is equal to the difference in y-coordinates (also called rise).
m = y^2 - y^1 / x^2 x^1
Substitute in the values of
x

Pedro bought 7 tickets to a basketball game. He paid a total of $147. Enter an equation, using x as your variable, to determine whether each ticket cost $21 or $22. Then enter the cost of the ticket.
Answers
Answer:
7 . x = 147
Step-by-step explanation:
7 multiplied by x equals 7x
( 7•x=7x)
then you need to get rid of the 7 so you divide by 7 on both sides.
(7x/7=x) (147/7=21)
x=21

In 1846 the depth of the river was 2.5 feet deep. In 1847 it rose 9%. This year, 1848, it dropped 6%. How deep is the river now?
Answers
Answer:
So the answer is 2.5615 feet.
Step-by-step explanation:
So the river is 2.5 feet deep, and when you find that 9% is, using the cross-multiplication formula to find the percent then 9% of 2.5 is 0.225, and when you add that to 2.5 you get 2.725, and when you find 6% of 2.725, you get 0.1635, and since it dropped, you subtract, and you end up with 2.5615
Hope I helped
The depth of the river in 1848 is 2.5615 feet.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The % formula is used to calculate a percentage of a whole in terms of 100. You may use this formula to express a number as a fraction of 100. If you look closely, calculating percentages indicated above can be readily computed using the formula below:
Percentage = (Value/Total Value) × 100
To solve this problem, we can start by finding the depth of the river in 1847 after it rose by 9%.
Depth in 1847 = 2.5 + (9% of 2.5)
Depth in 1847 = 2.5 + 0.225
Depth in 1847 = 2.725 feet
Next, we need to find the depth of the river in 1848 after it dropped by 6%.
Depth in 1848 = 2.725 - (6% of 2.725)
Depth in 1848 = 2.725 - 0.1635
Depth in 1848 = 2.5615 feet
Therefore, the depth of the river in 1848 is 2.5615 feet.
