Answer:
y = -2x + 8
Step-by-step explanation:
f(2) = 4 is the same as (2, 4) where x = 2 and y = 4
f(3) = 2 is the same as (3, 2) where x = 3 and y = 2
m is the slope of the line
b is the y-intercept
y = mx + b
To find the slope,
m = (y2 - y1)/(x2 - x1) = (2 - 4)/(3 - 2) = (-2)/(1) = -2
m = -2
y = -2x + b
To solve for b, take one of the two given values.
Using (2, 4)
4 = -2(2) + b
4 = -4 + b
b = 8
Using (3,2)
2 = -2(3) + b
2 = -6 + b
b = 8
y = -2x + 8
To double check b = 8,
The y-intercept is when x = 0.
y = -2(0) + 8
y = 8
(0, 8)

Answers

Answer:
non-leap years: 31/365leap years: 31/366Step-by-step explanation:
As a fraction of the number of days in a calendar year, it will depend on whether the year is a leap year.
non-leap years have 365 days, so 31 days is 31/365 years.
leap years have 366 days, so 31 days is 31/366 years.
_____
If you're asking for the purpose of computing interest, you need to be aware that "ordinary interest" counts 360 days in a year. 31 days would be 31/360 years. "Exact interest" counts 365 days in a year, so 31 days would be 31/365 years.
In astronomy, the definitions of "day" and "year" may vary, depending on the frame of reference and what direction in space marks the boundary of the period. The precise fraction will depend on how you define these terms and where the clock is located.

Find each percent of change round answers to the nearest tenth of a percent if necessary (25 is decreased to 18)
Answers
Answer:
[tex]\%Change = -28\%[/tex]
Step-by-step explanation:
Given
25 decreased to 18
Required
Determine the percentage change
This is calculated as follows:
[tex]\%Change = \frac{Initial\ Value - New\ Value}{Initial\ Value} * 100\%[/tex]
In this case:
[tex]Initial\ Value = 25[/tex]
[tex]New\ Value = 18[/tex]
So, the formula becomes
[tex]\%Change = \frac{18 - 25}{25} * 100\%[/tex]
[tex]\%Change = -\frac{7}{25} * 100\%[/tex]
[tex]\%Change = -\frac{7* 100\%}{25}[/tex]
[tex]\%Change = -\frac{700\%}{25}[/tex]
[tex]\%Change = -28\%[/tex]
Hence, the change is 28% decrease

Does a proportional relationship exist? Find the constant rate of change & interpret its meaning.
A. Yes, Every 1 day, sales increase by $1000
B. Yes, Every 3 days, sales increase by $1000
C. No, Every 2 days, sales increase by $500
D No. Every 3 day, sales increase by $30
Answers
Answer:
B. Yes, Every 3 days, sales increase by $1000
Step-by-step explanation:
A proportional relationship exists because the line cuts across the point of origin, (0, 0).
Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.
This shows proportional increase of $1,000 of sales, every 3 days.

The sums of 3 whole numbers taken in pairs are 12, 17 and 19. What is the least number?
Answers
Answer:
The least is 5
Step-by-step explanation:
Represent the numbers with x, y and z.
Such that:
[tex]x + y = 12[/tex]
[tex]y + z = 17[/tex]
[tex]x + z = 19[/tex]
Required
Determine the smallest number
Add the three equations:
[tex](x + y) + (y + z) + (x + z) = 12 + 17 + 19[/tex]
[tex](x + y) + (y + z) + (x + z) = 48[/tex]
Collect Like Terms
[tex]x + x + y + y + z + z = 48[/tex]
[tex]2x + 2y + 2z= 48[/tex]
Divide through by 2
[tex]x + y +z = 24[/tex]
Recall that:
[tex]x + y = 12[/tex]
[tex]y + z = 17[/tex]
[tex]x + z = 19[/tex]
Substitute 12 for x + y in [tex]x + y +z = 24[/tex]
[tex]12 + z =24[/tex]
[tex]z = 24-12[/tex]
[tex]z = 12[/tex]
Substitute 17 for y + z in [tex]x + y +z = 24[/tex]
[tex]x + 17 = 24[/tex]
[tex]x = 24-17[/tex]
[tex]x = 7[/tex]
Substitute 19 for x + z in [tex]x + y +z = 24[/tex]
[tex]19 + y = 24[/tex]
[tex]y = 24 - 19[/tex]
[tex]y = 5[/tex]
So:
The numbers are 7, 5 and 12 and the least is 5
14: 15 = 6: 19? Are in equal ratio? True
OR False
Answers
Answer:
False
Step-by-step explanation:
Given
[tex]14 : 15 = 6 : 19[/tex]
Required
True or false
[tex]14 : 15 = 6 : 19[/tex]
Convert ratio to fraction
[tex]\frac{14}{15} = \frac{6}{19}[/tex]
Cross Multiply:
[tex]14 * 19 = 15 * 6[/tex]
[tex]266 \neq 90[/tex]
Notice that both sides of the equation are not equal.
Hence, the ratio is false

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in: 2/3 hour?
Answers
Answer:
Jordan will cover 5.8 miles in 2/3 hours.
Step-by-step explanation:
Jordan bikes at a speed of 8 2/3 mph.
Unit rate:
[tex]8\frac{2}{3}=\frac{26}{3}=8.7[/tex] miles per hourSince Jordan bikes 8.7 miles in one hour, all we just need is to multiply 8.7 by 2/3 in order to determine the number of miles covered in 2/3 hours.
Therefore,
The number of miles covered in 2/3 hours = 8.7 × 2/3
= 5.8 miles
Therefore, Jordan will cover 5.8 miles in 2/3 hours.Answer:
5 7/9 miles
Step-by-step explanation:
8 2/3 * 2/3 = 5 7/9

Answer:
As the gradient gets more steep, the erosion will increase due to the increased velocity of the stream, hence making it easier to carry loads and erode the surface.
As the load of the stream increases, it will bring more debris and load with it, snowballing the amount of load/debris that the stream carries.
And finally, as the discharge of the stream increases, there is more stream to pick up loads, and erosion will increase.
TL;DR all three will increase erosion.

Answers
Answer:
16 marbles.
Step-by-step explanation:
Since your friend is blindfolded the only actual way for him to be completely sure that they picked out all 6 black marbles would be to pick out all of the marbles until none are left. As long as there is even one marble in the bag then your friend will still not be sure which color it is due to being blindfolded. Therefore, under these circumstances the answer would be 16 marbles.
