Answer:
[tex]Slope = -1[/tex]
[tex]y = -2[/tex] --- y intercept
[tex]x = -2[/tex] ---- x intercept
[tex]y = -x - 2[/tex] --- equation
Step-by-step explanation:
Given
Represent temperature with y and time with x
When
[tex]y = 0F; x = 2hrs\ before\ sunsets[/tex]
[tex]y = -4F; x = 2hrs\ after\ sunset[/tex]
Solving Slope;
[tex]Slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]Slope = \frac{-4 - 0}{2 - (-2)}[/tex]
[tex]Slope = \frac{-4 - 0}{2 +2}[/tex]
[tex]Slope = \frac{-4}{4}[/tex]
[tex]Slope = -1[/tex]
Using
[tex]Slope = \frac{y - y_1}{x - x_1}[/tex], we can get the equation
Where
[tex]Slope = -1[/tex]
[tex]x_1 = -2[/tex]
[tex]y_1 = 0[/tex]
This gives:
[tex]-1 = \frac{y - 0}{x -(-2)}[/tex]
[tex]-1 = \frac{y}{x +2}[/tex]
Cross multiply
[tex]y = -x - 2[/tex]
Take x as 0; to solve the y intercept
[tex]y = -0 - 2[/tex]
[tex]y = -2[/tex]
Take y as 0; to solve the x intercept
[tex]0 = -x -2[/tex]
[tex]x = -2[/tex]
Answer:Answer:
--- y intercept

Answer:
it is 237
Step-by-step explanation:
Answer: 237
Step-by-step explanation:
You do not to do order of operations for this problem
2 x 100 = 200
200 + 18 = 218
218 - 1 = 217

How to simplify The expression 5(x+1)-5x
Answer:
55 times x , 5 times 1 (keep the -5x after that)it will then be 5x+5-5xchange the x to be together 5x-5x+5The result will be 5Answer: 5
Step-by-step explanation:
5(x+1)-5x
distribute
=(5)(x)+(5)(1)+ -5x
=5x+5+ -5x
Combine like terms
5x+5+ -5x
= (5x+ -5x) + 5
= 0 + 5
= 5

A lion runs at a speed of 50 mph and a cheetah runs 78 mph. If they both run at a steady rate, how far will a cheetah run in the time it takes a lion to run 13.75 miles?
Answer:
21.45 mi
Step-by-step explanation:
Distance = speed × time
The time it takes the lion is:
13.75 mi = 50 mi/hr × t
t = 0.275 hr
The distance ran by the cheetah in that time is:
d = 78 mi/hr × 0.275 hr
d = 21.45 mi
Answer:
21.45 miles
Step-by-step explanation:
First, let's find the main ratio:
50:78
Now, let's bring a variable into the equation.
13.75:x
We can find the number to multiply by dividing 13.75 by 50 using long division.
13.75÷50=0.275
We need to find how many miles the cheetah ran, so we will multiply 78 and 0.275.
78·0.275=21.45
So, the cheetah ran 21.45 miles in the time it took the lion to run 13.75 miles.
1,000 grams
To convert kilograms to grams, you can use the ratio
1 kilogram
true or false
Answer:
True
Step-by-step explanation:
A Kilogram (kilo) is a unit of measuring metric mass. To perform this conversion you need to note that
1 Kilogram (kg) = 1000 grams
Which means that converting Kilogram to Grams would involve multiplying kilogram by 1000.
For example, 100 kg to grams = 100 * 1000 = 100,000 Grams

Find the flaw with the following "proof" that every postage of 3 cents or more can be formed using just 3-cent and 4-cent stamps.Basis Step: We can form postage of 3 cents with a single 3-cent stamp, and we can form postage of 4 cents using a single 4-cent stamp.Inductive Step: Assume that we can form postage of j cents for all nonnegative integers j with j ≤ k using just 3-cent and 4-cent stamps. We can then form postage of k + 1 cents by replacing one 3-cent stamp with a 4-cent stamp or by replacing two 4-cent stamps by three 3-cent stamps.Which of these statements describes a flaw in the proof?
Answer:
The main flaw of this proof is that it did not take into consideration the fact a 4 cent postage must be made with a 4 cent stamp and a 3 cent postage must be made with a 3 cent stamp but only looked at allocating the stamps based on the total amount of postage
Step-by-step explanation:
From the question we are told that
The proof is
Every postage stamp of three cents or more can be formed using just 3 cent and 4 cent stamps.
Basic Step : We can form postage of 3 cents with a single 3 cent stamp and we can form postage of 4 cents using a single four cents tamp
Inductive Step: Assume that we can form postage of j cents for all non negative integers j with j <= k using just 3 cent and 4-cent stamps. We can then form postage of k+1 cents by replacing one 3 cent stamp with a 4-cent or two 4-cent stamps with three 3-cent stamps
FLAW IDENTIFICATION
Looking the inductive step, the statement ''by replacing one 3 cent stamp with a 4-cent or two 4-cent stamps with three 3-cent stamps '' means that it is possible to use a 3-cent stamp for postage that requires a 4 -cent stamp and this is not correct according the statement in the basic step
Generally the main flaw of this proof is that it did not take into consideration the fact a 4 cent postage must be made with a 4 cent stamp and a 3 cent postage must be made with a 3 cent stamp but only looked at allocating the stamps based on the total amount of postage

Answer:
65°
Step-by-step explanation:
A triangle always will ad up to 180°. Therefore, if you subtract 130° from 180° you'll probably get 50° but that's the closest one to it.

5.8x - 1.4 = 16 What is the solution of the equation
Answer:
x = 3
Step-by-step explanation:
5.8x - 1.4 = 16 {add 1.4 to both sides}
5.8x = 16 + 1.4
5.8x = 17.4 {Divide both sides by 5.8}
x = 17.4/5.8
x = 3
