Step-by-step explanation:
As x increases four units from -4 to 0, y decreases four units from 0 to -4
slope m = Δy/Δx = -4/4 = -1
The y intercept is at (0, -4) so b = -4
y = -1x + -4
y = - x - 4
as m is negative, slope is negative

If you built a model of the Empire State Building that is proportional to the real building. The height of the Empire State Building is 1,250 feet. If the scale of your model is 1 inch = 50 feet how tall is your model?
Answers
12in = 1ft, 12in * 50 = 600.
Which means the model you’ll be making will be a 1:600 ratio model. If we find out how many inches are in 1,250 feet, and divide that number by 600, we will get our answer.
1,250 * 12 = 15,000.
So 1,250 feet equate to 15,000 inches. Now we must divide 15,000 by 600.
15,000 ÷ 600 = 25.
So your model will be 25 inches (or 2’1” [2 feet & 1 inch] tall).

A tin contains 425g baked beans in sauce. The tin itself weighs 60g. How much will a pack of 6 tins weigh in kilograms
Answers
Answer:
2.91 Kg
Step-by-step explanation:
Tin weighs 60g, it contains 425g of baked beans, add that together to get a full tin of baked beans
= 485.
Multiply by 6 to get the total amount in grams
= 2910g.
Turn that into Kg.
2.91 kg.
The weight of 6 tins will be 2.19 Kg,
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Tin weighs 60g, it contains 425g of baked beans,
So, the total weight along with tin
= 425 + 60
= 485 g
Now, the weight of 6 tins
= 485 x 6
= 2190 g
= 2190/1000 Kg
= 2.19 Kg
Hence, the weight is 2.19 Kg.

A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode?
Answers
Answer:
3.25 seconds after B launches
Step-by-step explanation:
In the 0.25 seconds before A launches, B will have traveled ...
distance = speed · time
distance = (240 ft/s)(0.25 s) = 60 ft
The speed of A is 20 ft/s faster, so will close that 60 ft gap at the rate of 20 ft/s. It will take ...
time = distance/speed
time = 60 ft/(20 ft/s) = 3 s
The fireworks will be at the same height 3 seconds after A is launched. That is 3.25 seconds after B is launched.
_____
Additional comment
Their heights will be (3 s)(260 ft/s) = 780 ft = (3.25 s)(240 ft/s).

Step-by-step explanation:
We can use the FOIL method to multiply the terms together and then find the values in our trinomial. First, the F in FOIL. It stands for first, and we need to multiply the first terms in the two expressions. These terms are 2x and x. Multiplying 2x by x gives us 2x², so that's our first term.
Next, the O in FOIL. It stands for outside, and we need to multiply the terms on the very left and the very right. These are 2x and -3, and multiplying 2x by -3 gives us -6x. That's our second term.
Now, the I in FOIL. It stands for inside, so we need to multiply the terms in the middle of the expressions. Those are 8 and x, and we multiply those together to get 8x. That's our third term.
Finally, the L in FOIL. This stands for last; we need to multiply the last terms of each expression. Those are 8 and -3, and we can multiply those to get -24. Now we can get all our terms added together and simplify as needed.
2x² - 6x + 8x - 24
We can simplify -6x and 8x since they are like terms.
2x² + 2x - 24
And there is our trinomial. Hopefully that's helpful! :)

A playground is rectangular with a length of 78 miles. If the area of the playground is 820 square miles, what is its width? Input your answer as a fraction.
Answers
Answer:
10.5, [tex]10\frac{1}{2}[/tex], or [tex]\frac{21}{2}[/tex]
Step-by-step explanation:
To solve, you can use a variable (x) to represent the width.
The equation for area is A=L×W
So the Area is 820 and the length is 78.
820= 78w
Isolate the variable to solve.
w=10.5128....
If you round, it will be 10.5
10.5 as a fraction is [tex]10\frac{1}{2}[/tex] or [tex]\frac{21}{2}[/tex]

C=π5²
C=78.5
The circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle).
It is given that:
A gardener makes a new circular flower bed. The bed is ten feet in diameter.
D = 10 feet
The radius r = D/2 = 10/2 = 5 feet
A = πr²
π = 3.14
A = π(5)²
A = 78.5 square feet
The circumference:
C = 2πr
C = 2(3.14)(5)
C = 31.4 feet
Thus, the circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.

so, 152/8 168/8
19 to 21
Answer:
D. 21 to 23
Step-by-step explanation:
1. First, you use the biggest number of guests just to be safe. Since there will be about 174 guests attending
2. you divide 174 by the number of seats a round table can hold. Since the number is 8, you 174/8 which is 21.75.
3. You round up to the biggest number of tables that has the number 21 in it.
4. Your answer is D. 21 to 23
A file that is 249 megabytes is being downloaded. If the download is 15.7% complete, how many megabytes have been downloaded? Round your answer to the

Percentages are out of a hundred, so 15.7% is 15.7 out of 100, aka 15.7/100, which is 0.157.
Now, you just need to multiple this number by 249 megabytes to get 0.157 * 249 = 39.093 which rounds to 39.1
Given f(x)=-x+2, find f(-5)
Answers
Answer:
7
Step-by-step explanation:
f(-5) means you have to plug -5 in for x.
f(x)=-x+2, so f(-5)=-(-5)+2=5+2=7
f(-5)=7
Answer:
Step-by-step explanation:
Simply plug -5 into the equation where an x is:
f(x) = -x + 2
f(-5) = -(-5) + 2
Two negatives make a positive so:
f(-5) = 5 + 2
f(-5) = 7
