examine the graph below. select the solutions to the graph from the following points. select three that apply.
Answer:
Options (1), (2), (3)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Given line on the graph is passing through two points (-3, 0) and (0, 1).
Slope of this line will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{1-0}{0+3}[/tex]
= [tex]\frac{1}{3}[/tex]
y-intercept of the line 'b' = 1
Equation of the line will be,
y = [tex]\frac{1}{3}x+1[/tex]
If the points given in the options satisfy the equation, they will be the solution of the line.
Option (1),
For (3, 2),
2 = [tex]\frac{3}{3}+1[/tex]
2 = 2
True.
(3, 2) is the solution.
Option (2)
For (21, 8),
8 = [tex]\frac{21}{3}+1[/tex]
8 = 8
True.
(21, 8) is the solution.
Option(3)
For (-15, -4),
-4 = [tex]\frac{-15}{3}+1[/tex]
-4 = -4
True.
(-15, -4) is the solution.
Option (4)
For (12, 9)
9 = [tex]\frac{12}{3}+1[/tex]
9 = 5
False
(12, 9) is not the solution.
Option (5)
For (-6, 1)
1 = [tex]\frac{-6}{3}+1[/tex]
1 = -1
False
(-6, 1) is not the solution.
Therefore, Options (1), (2), (3) are the solutions.

Tickets for a concert cost eight dollars for the main floor and six dollars for the balcony If 1125 tickets were sold and the tickets sales total 8050 how many tickets of each kind were sold
Answer:
650 tickets for the main floor and 475 tickets for the balcony were sold.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=1125 (1)
8x+6y=8050 (2), where:
x is the number of tickets for the main floor
y is the number of tickets for the balcony
First, you can solve for x in (1):
x=1125-y (3)
Second, you can replace (3) in (2):
8(1125-y)+6y=8050
9000-8y+6y=8050
9000-2y=8050
9000-8050=2y
950=2y
y=950/2
y=475
Third, you can replace the value of y in (3) to find x:
x=1125-y
x=1125-475
x=650
According to this, the answer is that 650 tickets for the main floor and 475 tickets for the balcony were sold.
A square of side x is cut out of a larger square of side y. What is the area of the remaining
figure?
Answer:
The area of the remaining figure is [tex]y^2-x^2[/tex]
Step-by-step explanation:
Area of the Square Shape
Given a square of side length x, the area is calculated by the formula:
[tex]A_x=x^2[/tex]
It's given a square of side x is cut out of a larger square of side y. Please refer to the image below.
The area of the square of side length y is:
[tex]A_y=y^2[/tex]
The shaded area of the remaining figure is the difference between both areas:
[tex]A=A_y-A_x[/tex]
[tex]A=y^2-x^2[/tex]
The area of the remaining figure is [tex]\mathbf{y^2-x^2}[/tex]

Answer:
you need to find out how many miles per hour irst then see how many itll be in 24 hours
Step-by-step explanation:
Answer:
D = 6.2t, where t is in hours
Now, solve for 24 hours for t.
D = 6.2(24) = 148.8 miles in 24 hours.
Step-by-step explanation:
First, find out how far the butterfly can fly in 1 hour.
93 miles / 15 hours = 6.2 miles per hour
Let D = the distance in miles the butterfly can fly in t hours.
Your equation will be
D = 6.2t, where t is in hours.

A boat traveled 126 miles downstream and back. The trip downstream took 6 hours. The trip back took 42 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
The answer is
Speed of the boat in still water= 12mph
Speed of current= 9mph
Step-by-step explanation:
let x= speed of the boat in still water
let y= speed of current
DATA WE HAVE
with current
rate- x+y
time- 6 hours
distance- 126 miles
rate= 126/6= 21
against current
rate- x-y
time- 42hr
distance- 126 miles
126/42= 3
Now, we add these two equations vertically.
x-y=3
+
x+y=21
2x = 24
Now we divide each side by 2
2x/2 24/2
x= 12
The speed of the boat in still water is 12mph
NOW WE HAVE HALF OF THE ANSWER
if x+y= 21
then
12+y=21
subtract 12 from both sides
y=9
The speed of the current is 9mph
Checking)
12+9=?21
21=21
12-9=?3
3=3
I hope this helped! If you have any questions, dm me on insta celinesaydawi
The speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.
Given that a boat traveled 126 miles downstream and back, and the trip downstream took 6 hours, while the trip back took 42 hours, to determine what is the speed of the boat in still water and what is the speed of the current, the following calculations must be performed:
(126/2) / 6 = 10.5 mph downstream (126/2) / 42 = 1.5 mph against current (10.5 - 1.5) / 2 = 4.5 mph (current speed) 10.5 - 4.5 = 6 1.5 + 4.5 = 6 6 mph = speed of the boat in still water
Therefore, the speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.

You read the first 20 pages of a book in 25 minutes. You read 36 pages in 45 minutes. Is the number of pages read
proportional to your time?
(i’ll give brainliest to best answer)
Answer:
proportional
Step-by-step explanation:
20 : 25 :: 36 : 45
Product of means = 25*36 = 900
Product of extremes = 20 * 45 = 900
Product of means = Product of extremes
So, the number of pages read is proportional to your time
If you are rolling two dice (numbered 1-6), what is the probability that the first die shows a 4 and the second die shows a 2?
Answer:
Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.
1 out of six for both numbers
you have six numbers and 1-6 therefor its a 1 outta 6 chance

The stopping distance (s) of a truck varies directly as the square of its speed (v). If a truck travelling at 50 mph requires 200 feet to stop, find the stopping distance for a truck travelling at 65 mph.
Answer:
The distance is 338ft
Step-by-step explanation:
Given
Represent distance with s and velocity with v:
When
[tex]s = 200\ ft[/tex]
[tex]v = 50mph[/tex]
Required
Determine the distance when velocity is 65mph
From the question, we understand that:
[tex]s\ \alpha\ v^2[/tex]
Convert to equation
[tex]s\ = kv^2[/tex]
Substitute 200 for s and 50 for v
[tex]200 = k * 50^2[/tex]
[tex]200 = k * 2500[/tex]
Make k the subject:
[tex]k = \frac{200}{2500}[/tex]
[tex]k = \frac{2}{25}[/tex]
To get s when v = 65.
Substitute 65 for v and 2/25 for k in [tex]s\ = kv^2[/tex]
[tex]s = \frac{2}{25} * 65^2[/tex]
[tex]s = \frac{2}{25} * 4225[/tex]
[tex]s = \frac{8450}{25}[/tex]
[tex]s = 338\\[/tex]
Hence, the distance is 338ft
A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year period, models the population growth. How many foxes will there be after 26 years
Answer:
640 foxes
Step-by-step explanation:
The actual formula is [tex]y = 40 * 4^{x}[/tex]
Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.
26 / 13 = 2 periods
Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...
[tex]y = 40 * 4^{x}[/tex]
[tex]y = 40 * 4^{2}[/tex]
[tex]y = 40 * 16[/tex]
[tex]y = 640[/tex]
Finally, we can see that there should be 640 foxes after 26 years.
