Answer:
Step-by-step explanation:
f(2) = -2 means that one of the coordinates of this line is (2,-2)
f(1) = 1 means that another coordinate of this line is (1, 1)
This is because the general notation is f(x) = y
Now we use the equation y = mx + b, where we can find the slope, m, and then plug in one of the points to solve for the y-intercept, b
m = y2 - y1 / x2 - x1
m = 1 - (-2) / 1 - 2
m = -3
Arbitrarily choose one of the two coordinates to plug in to find the y-intercept. I chose (1,1) here:
1 = -3(1) + b
b = 4
Therefore, the linear function is y = -3x + 4, or f(x) = -3x + 4
e+ 7=15
a(22
b(8
c(-8
d(-22
Answer:
B) 8
Step-by-step explanation:
e + 7 = 15
Subtract 7 from both sides:
e = 8
Your answer is B

On Tuesday at 2 p.m., the ocean’s surface at the beach was at an elevation of 2.2 feet. Winston’s house is at an elevation of 12.1 feet. The elevation of his friend Tammy’s house is times the elevation of Winston’s house.
Part A
How many times greater is the elevation of Winston’s house than the elevation of the ocean’s surface at 2 p.m.?
Part B
What is the elevation of Tammy’s house?
Part C
How many times greater is the elevation of Tammy’s house than the elevation of the ocean’s surface at 2 p.m.?
Part D
On Wednesday at 9 a.m., Winston went diving. Near the beach, the ocean’s surface was at an elevation of -2.5 feet. During his deepest dive, Winston reached an elevation that was times the elevation of the ocean’s surface. What elevation did Winston reach during his dive
Part E
While diving, Winston stopped at a point located halfway between his deepest dive and the ocean’s surface. At what elevation was Winston when he stopped halfway?
Part A.)
12.1 / 2.2 = 5.5
So, the elevation of Winston's house is 5.5 times greater than the elevation of the ocean at 2 p.m.
Part B.)
My apologies if any of the following equations is not the right number, I had looked up the equation for the right number.
12.1 x 3.5 = 42.35
So the elevation of Tammy's house is 42.35.
Part C.)
42.35 / 2.2 = 19.25
the elevation of Tammy's house is 19.25 times greater than the elevation of the ocean.
Part D.)
Had to look for the number again. Next time, could you possibly make sure that all of the numbers are here? It makes it a lot easier.
-2.5 x 20.2 = -50.5
Winston reached an elevation of -50.5 feet.
Part E.)
-50.5 / 2 = -25.25
He had stopped at -25.25.
Again, my apologies if some numbers are incorrect. You did not give them, so I went looking for them.

_____ is used to explore large amounts of data for hidden patterns to predict future trends. Data governance Data mining Linear regression Drill down
Exploring large amount of data in other to explore underlying trends which cannot be uncovered by visual inspection or simple algorithms are analysed using Data mining.
Data mining are often performed using a network of interconnected computed or networks with very high processing capability and can handling high computational complexity due to the very large amount of data involved when data is being mined.
Linear regression are used on small data sets which cannot be compared to the vast amount of data involved in data mining.
Hence, data mining helps to uncover trends when exploring very large datasets.

Answer:
$60
Step-by-step explanation:
You will pay $60 for a item with original price of $80 when discounted 25%. In this example, if you buy an item at $80 with 25% discount, you will pay 80 - 20 = 60 dollars.
Answer:
$60
Step-by-step explanation:
Price of rabbit: 80
discount: 25 %
> 25% of 80
= 25 ÷ 100 × 80
= 20
Price after discount: 80 - 20
= 60
Price of the rabbit after the discount is $60
