Answer:
Answer choice A. Slope -1
Step-by-step explanation:
If we plot the two points on a graph we can see that the points go from left to right, starting from a higher point to a lower point. This means the slope is negative. B and D are the same choice, but just in different words, and 0 cannot be positive or negative. and C is positive, not negative. So it is A. I hope this helps, and I hope it's not wrong, but I don't think it is.

In City A, the temperature rises 4F from 8 A.M. To 9 A.M. Then the temperature drops 7F from 9 A.M. To 10 A.M. In City B, the temperature drops 6F from 8 A.M. To 9 A.M. Then the temperature drops 2F from 9 A.M. To 10 A.M. Write an expression that represents the change in temperature from 8 A.M. To 10 A.M. For each city. Simplify and interpret each sum.
Answer:
Follows are the solution to this question:
Step-by-step explanation:
The general term for temperature variations from 8 am to 10 am:
[tex]\to \delta_{S - 10}=\delta_{S -9}+\delta_{S-10}[/tex] Where [tex]\delta[/tex] represents a transition throughout the time interval subscribed to.
In this, the city of A:
[tex]\to \delta_{S-10}=4-7= -3^{\circ}\ F[/tex]
In this, the city of B:
[tex]\to \delta_{S-10}=-6-2= -8^{\circ}\ F[/tex]
It decrease of 3° (non-value) overall in city A.
Temporarily, in city B, is 8° C. City B has a greater temperature change (8 vs. 3) between A and B.

Answer:
D. 10x^2+4x+3
Step-by-step explanation:
You get this by adding all the terms!
Answer: D. 10x^2 + 4x + 3
To find the combined area, add both of the areas together.
A = (3x^2 - x + 7) + (7x^2 + 5x - 4) (Remove the parentheses)
A = 3x^2 - x + 7 + 7x^2 + 5x - 4 (Combine the like terms)
A = 10x^2 + 4x + 3
∴ the combined area of Tiffany's fence and lawn is 10x^2 + 4x + 3.
please help this question is making me angry it keeps saying it's wrong please I'm begging you
Answer:
y = 1/7x + 23/7 or y = 1/7x + 3 and 2/7
Step-by-step explanation:
If you are learning about this, I suppose you know the formula or how to get the slope. You want to divide the rise over run or take the two y values divided the two x values:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The two points we have are (-2, 3) and (5, 4)
So:
4 - 3 / 5 - (-2)
1 / 5 + 2
Slope: 1 / 7
Now we want to find b in y = mx + b,
We can write it as y = 1/6x + b, then plug in a y and x value:
3 = 1/7(-2) + b
3 + 2/7 = b
b = 23/7
We can check by using the other point we have:
4 = 1/7(5) + b
4 - 5/7 = b
b = 23/7 or 3 and 2/7
Then the equation is: y = 1/7x + 23/7

Which point is located in quadrant IV?
(–2, –4)
(–2, 4)
(2, –4)
(2, 4)
Answer:
(-2, 4)
Step-by-step explanation:
If you look at the quadrants on the graph, you could see that quadrant I holds only positive values (+, +). For quadrant II, it would hold (-, +) values. For quadrant III, it would hold (+, -) values. Lastly quadrant IV would hold (-, -) values.
So to answer the question, only (-2, 4) would be correct.
I also attached a graph of all the quadrants for you, just to understand the where all the positive and negative values are on the graph when it comes to quadrants.
Hope this helped!

Answer: 20.1
Step-by-step explanation: Based on triangle sum theorem all angles add up to 180. 3x-11+6x-10+x=180
Combine like terms. 10x-21=180
Add 21 to both sides. 10x=201
Divide by 10 on both sides. X=20.1

a person bikes 2 1/2 miles at constant rate in 1/8 of an hour what distance , in miles , does the person bike in an hour
Answer: The person bike 20 miles in an hour.
Step-by-step explanation:
Given: At a constant speed, a person travels [tex]2\dfrac12[/tex] miles in [tex]\dfrac18[/tex] hour.
As [tex]2\dfrac12=\dfrac{2\times2+1}{2}=\dfrac{5}{2}[/tex]
So, in [tex]\dfrac18[/tex] hour, distance traveled = [tex]\dfrac52[/tex] miles
As time and distance are proportional, Multiply 8 om both sides , we get
In 1 hour, distance traveled = [tex]\dfrac52\times8[/tex] miles
[tex]=5\times4[/tex] miles= 20 miles
Hence, the person bike 20 miles in an hour.

x = -4
1-3x + 2y = 4
Answer:
-3x+2y=14
-3(-4)+2y=14
12+2y=14
12+2y=14
subtract 12 both sides
2y=2
divide by 2
y= 1
explain how to find the least common multiple of two numbers.
Answer:
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
Step-by-step explanation:
Answer:
First convert numbers into prime numbers. find which number(s) is/are repeating. Multiply all numbers execpt for the number that repeat. Multiply those once.
Step-by-step explanation:
12 = 3*2*2
14 = 2*7
One 2 repeats
3*2*2*7 = 21*4 = 84
Lcm(12, 14) = 84
x+y=-11
convert from standard form to slope intercept
Answer:

The smaller brackets around 2 indicate that minus is being multiplied by 2 making it -2. As the signs of 1and 3 are the same i.e + they both are added and the answer is 4. Now 4 has the +ve sign and 2 has the -ve sign so 2 is subtracted from 4 and we get a +ve 2 . Now 2 raise to power 3 gives 8 which is the required number.
Only 2 raised to power 3 gives a 8. any other number like 3 or 1 raise to power does not give an eight.
Which city is cooler, Mobile (3°F) or Memphis (9°F)?
Answer:mobile 3f
Step-by-step explanation:
Answer:
Mobile is cooler. 3F is lower than 9F. In celsius, 3F would be -16 while 9F would be -12. Both cities would be really cold, but Mobile would be colder.

A rectangular swimming pool measures 60 meters in length and 30 meters in width. Joey creates a scale drawing of this pool using the scale 5 cm : 12 m. Find the length, width and perimeter of the pool in Joey's scale drawing. Be sure to include units in your answer.
Answer:
Length = 25cm
Width = 12.5 cm
Perimeter = 75cm
Step-by-step explanation:
Given that:
Actual measurement of rectangular swimming pool:
Length = 60 m
Width = 30 m
Scale = 5cm : 12 m
dimension of scale drawing
Length = 5/12 * 60 = 25cm
Width = 5/12 * 30 = 12.5cm
Perimeter of Scale drawing :
2(length + Width)
2(25cm + 12.5cm)
2(37.5cm)
= 75cm
