I need help with this
Step-by-step explanation:
I think the answer should be C
Answer: A
(2, -4) and (0,4);
x, y x, y
A. y = -4x +4; substitute the pairs
(2,-4)
-4 = -4(2) + 4 = -4; -4 = -4
(0,4)
4 = -4(0) + 4 = 4; 4 = 4
B. y = -4x - 4
(2, -4)
-4 = -4(2) - 4 = -12; -12 ≠ -4
(0,4)
4 = -4(0) - 4 = -4; -4 ≠ 4
C. y = 4x - 4
(2, -4)
-4 = 4(2) - 4 = 4; 4 ≠ -4
(0,4)
4 = 4(0) - 4 = -4; -4 ≠ 4
D. y = 4x + 4
(2, -4)
-4 = 4(2) + 4 = 12; 12 ≠ -4
(0,4)
4 = 4(0) + 4 = 4; 4 = 4
Answer A works out for both ordered pairs.

Answer: See the diagram below
==========================================================
Explanation:
She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.
---------------------
For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)
|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.
---------------------
The last thing to do is find the mean of the set {10,4,1,4,11}
add: 10+4+1+4+11 = 30
divide by five: 30/5 = 6
The mean absolute deviation (MAD) is 6
This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.
There is a 15% of sale on a play station five . If the original cost is $700 , what is the sale price on the play station 5 .
Price of the playstation 5 = 595
Answer:
$995
Step-by-step explanation:
First, we have to multiply 700 by 15.
700
x. 15
---------
3500
+700
---------
10500
After that you must move the decimal (starts from the right) 2 to the left
10500------>105.00
Once you get 105.Subtract 700-105
700
-105
----------
$595
Therefore the sale price is $595

Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole. Relative to ground level, what is the elevation of the hole after placing the shrub in the hole? Enter your answer as a mixed number in simplest form by filling in the boxes.
Answer:
15/6
Step-by-step explanation:
(20/9) ft of the hole is elevated after the shrub was placed.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis and results of the given problemGiven is that Malik digs a hole at a rate of 2/3 feet every 15 minutes. After digging for 60 minutes, Malik places a shrub in the hole that fills exactly 5/6 feet of the hole.
In 15 minutes, the depth of hole digged is (2/3) feet.
In 1 minute, the depth of hole digged is {(2/3)/15} feet.
In 60 minutes, the depth of hole digged will be {(2/3)/15} x 60 = 8/3 ft.
The hole filled after placing the shrub will be -
(5/6) x (8/3)
5/6 x 8/3
5/3 x 4/3
20/9
Therefore, the (20/9) ft of the hole is elevated after the shrub was placed.

Solve for b.
b - 7 = -20
A. b = -27
B. b = -13
C. b = 13
D. b = 27
Answer:
B. b = -13
Step-by-step explanation:
b - 7 = -20
move variables and numbers to different sides of the equal sign by adding 7 to both sides
b - 7 + 7 = -20 + 7
b = -13

y = 5x + 4
What is the slope. Please help.
Answer:
The slope is 5
Step-by-step explanation:
Our equation:
y = mx + bGiven equation:
y = 5x + 4Now, let's compare both equations to see which is the slope.
=> y = mx + b = y = 5x + 4
We can clearly see that m = 5.
Therefore, the slope is 5.

193 miners need to ride the elevator to the bottom of the mine. The elevator can hold 7 miners at a time. How many miners will be in the elevator on its last trip?
Answer:
4
Step-by-step explanation:
193/7=27 with a remainder of four.
[tex]\huge \bf༆ Answer ༄[/tex]
Here's the solution ~
There are total of 193 mimers and each time the elevator can carry 7 miners, now divide the numbers and the remainder ww get gives the number of people left at last, that is also equal to the number of miners in the last trip since they are the last group among them.
[tex] \sf193 \div 7[/tex]On dividing, we get quotient = 27 and remainder as 4
therefore, 28th trip will be the last trip carrying 4 miners.
I hope that helps ~
