21. Which equation best represents the line of regression in the following
scatter plot?
O A) y = 2x + 1
O B) y = -2x + 1
O C) y = -1/2x + 3
OD) y = x + 2x + 4
Answer:
D
Step-by-step explanation:
Select all equations that have graphs with the same y-intercept. y = 3x - 8 y = 3x - 9 y = 3x + 8 y = 5x - 8 y = 2x - 8 y = ⅓x - 8

Samantha went to a concession stand and bought three pretzels and four sodas and paid a total of $11.25 for them. Raza went to the same stand and bought five pretzels and two sodas and paid a total of $8.25.
(a) Could pretzels have cost \$1.75 each and sodas $1.50 each ? How can you evaluate based on the information given ?
(b) Letting x equal the unit cost of a pretzel and letting y equal the unit cost of a soda, write a system of equations that models the information given .
(c) Solve the system of equations using the elimination method or a matrix,
(d) Leah went to the same concession stand and bought two sodas, how many pretzels would she need to buy so that she spent the same amount on both
Answer:
No, because their respective prices are $0.75 and $2.25
Step-by-step explanation:
Let's assume that the price of each pretzel is x and the price of each soda is y
3x + 4y = 11.25_____ equation 1
5x + 2y = 8.25_____ equation 2
Multiply equation 2 by the figure 2 so as to have both equation sharing the same coefficient of y
10x + 4y = 16.5____ equation 1
3x + 4y = 11.25____ equation 2
Now subtract equation 2 from 1
7x = 5.25
X = 5.25/7
X = 0.75
Now substitute x = 0.75 in equation 1
10x + 4y = 16.5
10(0.75) + 4y = 16.5
7.5 + 4y = 16.5
4y = 16.5 - 7.5
4y = 9
Y = 2.25
Therefore,the cost of each pretzel is $0.75 while that of soda is $2.25

The computation is shown below:
Here we applied the pythagoras theroem
Given that
Diagonal of 18.4 feet
Width of 7 feet
So, the area would be
= 18.4^2 - 7^2
= 17

What is an equation of the line that passes through the point (-1,-3)(−1,−3) and is parallel to the line 6x-y=16x−y=1?
Answer:
x = -1
Step-by-step explanation:
[tex]6x - y = 16x - y - 1\\-10x = -1\\x = 1/10[/tex]
Since this is the equation of a vertical line, that means that the new one will also just be in the form x = ?.
Since the x - value is -1, the equation is x = -1

Hey there!
The answer is 6:54
The time on the clock shows 6:20, because the hour hand is after the 6, and the minute hand is on the 4 (which we multiply by 5 to get the minutes).
If it takes her 8 minutes to walk to the bus, 10 to pack lunch, and 16 to get dressed, that's a total of 8 + 10 + 16 minutes, or 34 minutes.
So, we add that to the minutes, so 20 + 34 = 54, therefore the time is 6:54 when she arrives.

mary works for a commission of 12% on all goods she sell for the month if her basic salary is 3000 per month and she sells $2500 worth of goods for a certain month calculate mary's gross salary for that particular month
Answer:
3300
Step-by-step explanation:
Formula
Gross Salary = Basic + Commission
Givens
Basic = 3000
% = 12%
Solution
Gross = 3000 + 12/100 * 2500
Gross = 3000 + 30000/100
Gross = 3000 + 300
Gross = 3300

Step-by-step explanation:
(-7+1)/(5-1)=-6/4= -3/2 is the slope
answer is C
Answer:
C
Step-by-step explanation:
The formula for slope is rise/run
Rise is the difference between the y coordinates
Run is the difference between the x coordinates
To find the rise and run:
ex.
(a, b), (c, d)
rise:
d-b
run:
c-a
Slope:
d-b/c-a
In this situation:
rise:
-7-(-1)
run:
5-1
Slope:
-7-(-1)/5-1
= -6/4
=-3/2
So the answer is C

Airplanes use radar (radio waves) to measure distances.
The plane is at a height of 5200 m. The airport is 10.2 km away.
How far does the plane need to travel before it lands?
a) 11.4 km
b) 10.4 km
c) 5200 km
d) 10.2 km
Answer:
10.2 km
Step-by-step explanation:
I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.
Answer:
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Step-by-step explanation:
Let
Mass of brown eggs = x
Mass of white eggs = y
3y + 2x = 13 (1)
5y + 4x = 24 (2)
Multiply (1) by 5 and (2) by 3 to eliminate y
15y + 10x = 65 (3)
15y + 12x = 72 (4)
Subtract (3) from (4)
12x - 10x = 72 - 65
2x = 7
x = 7/2
x = 3.5
Substitute x = 3.5 into (1)
3y + 2x = 13 (1)
3y + 2(3.5) = 13
3y + 7 = 13
3y = 13 - 7
3y = 6
y = 6/3
y = 2
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
The value of y varies inversely with x, and y=-2 when x=4
What is the equation?
