Answer:
No, the slope's are not the same
Short-cut explanation:
Simply count the spaces between the two lines at the very top then compare to the number of space between at the very bottom of the graph.
There are 2 spaces between the two lines at the top. There seems to be 1 and 1/2 spaces at the very bottom.
[tex]2\neq 1.5[/tex] , therefore, not parallel.
If they are the same, then it is parallel. Although, in this case, it is not(Shown on the graph).
Answer:
Basic Concept:
A criterion for parallel lines is that they should have equal slopes. If the slopes of these lines is equal, these lines are parallel and are intersecting if the slopes are not equal
let the line on the left be 'line 1' and the line on the right be 'line 2'
Slope of Line 1:
We are given 2 points on the line and we will use them to get its slope
We know that the slope of a line is the change in its y-ordinate divided by its change in x - ordinate
The points given are: (-3 , -5) and (0 , 4)
Change in x:
The change in x of these 2 coordinates can be calculated by subtracting their x- ordinates
Change in x (Δx) = x1 - x2
Δx = -3 - 0
Δx = -3
Change in y:
The change in y of these 2 can similarly be calculated by subtrating the y-ordinates
change in y (Δy) = y1 - y2
Δy = -5 - 4
Δy = -9
Slope of the line:
Since the slope = Δy / Δx
Replacing the known values:
Slope = -9 / -3
Slope = 3
Therefore, the slope of 'line 1' is 3
Slope of Line 2:
We are given 2 points on the line and we will use them to get its slope
We know that the slope of a line is the change in its y-ordinate divided by its change in x - ordinate
The points given are: (0 , -6) and (4 , 4)
Change in x:
The change in x of these 2 coordinates can be calculated by subtracting their x- ordinates
Change in x (Δx) = x1 - x2
Δx = 0 - (4)
Δx = -4
Change in y:
The change in y of these 2 can similarly be calculated by subtrating the y-ordinates
change in y (Δy) = y1 - y2
Δy = -6 - 4
Δy = -10
Slope of the line:
Since the slope = Δy / Δx
Replacing the known values:
Slope = -10 / -4
Slope = 5/2
Therefore, the slope of 'line 2' is 5/2
Conclusion:
We have calculated the slope of both the lines.
now, we will compare the slopes to find out if the lines are parallel or not
Slope 1 = 3
Slope 2 = 5/2
Since the slopes are NOT equal, the lines are not parallel
How do you Simplify 4c+c+6c
Answer:
11c
Step-by-step explanation:
They are like terms meaning they all have the same variable you can just add them.
4c+c+6c
11c
Answer:
11c
Explanation:
We are given the expression:
4c+c+6c
We can simplify by combining like terms. All three terms have a “c” so they can all be combined.
Factor out a “c” and add the coefficients.
4c+1c+6c
(4+1+6)c
(11)c

4c+c+6c simplified is 11c
The mailing tube shown below is 36 inches long, 6 inches wide, and 5.2 inches deep.
The bases are equilateral triangles. How much cardboard is used to make the tube?
The amount of cardboard = Surface area of a triangular prism = 679.2 in.²
What is the Surface Area of a Triangular Prism?Surface area of a triangular prism = (perimeter of base × length of the prism) + (2 × Base Area)
= (S1 +S2 + S3)L + bh
The mailing tube is a triangular prism with an equilateral triangular base, and has the following given values:
s1 = 6 in.s2 = 6 in.s3 = 6 in.L = 36 in.b = 6 in.h = 5.2 in.Plug the values into the surface area formula to find the amount of cardboard that would be used to make the tube:
Amount of cardboard = Surface area of a triangular prism = (6 + 6 + 6)36 + (6)(5.2) = 679.2 in.²

If the ice mass were deposited on the total Earth's surface, it would be 58.82 meters or 192.92 feet.
How to find out the answer?The formula that can be used is:
The total volume of the ice / total surface = thickness of the layer.30 million cubic kilometers / 510 million squared kilometers = 0.5882 kilometers or 58.82 meters.How to convert meters to feet?To convert meters to feet multiply the result by 3.28.

Laura is walking quickly and finds that she travels 54 feet in a span of 12 seconds. Which of the following is the speed at which Laura is walking? (1) 4.5 feet per second
(2) 4.75 feet per second
(3) 5.25 feet per second
(4) 5.5 feet per second
Answer:
(1) 4.5 feet per second
Step-by-step explanation:
Given;
distance traveled by Laura, d = 54 feet
time to taken for Laura to cover this distance, t = 12 seconds
Laura's speed is given by the following equation;
speed = distance / time
Laura's speed = 54 ft / 12 s
Laura's speed = 4.5 feet per second
Therefore, the speed with which Laura is walking is 4.5 feet per second.
If the price of a yo-yo in a shop increased by 20% and is now $18.00, what was the original price?
So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.
Hope it helped :)
The original price was $15.00
The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:
18 = x × (1 + 20%)
18 = x × 1.20
18 = 1.20x
x = 18 / 1.20
x = $15.00
In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

When it comes to fat, there's one type you don't want to cut back on: omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. ALA (alpha-linolenic acid), another omega-3 fatty acid, is found in plant sources such as nuts and seeds. Not only does your body need these fatty acids to function, but also they deliver some big health benefits.

The price of a calculator depends on the number of these calculators you buy.
The table gives information about the prices of this calculator.
Number of calculators
Price of each calculator
1-29
£3.85
30-99
£3.65
100 or more
£3.49
Mr Edwards wants to buy some of these calculators.
He has £200 to spend.
Work out the greatest number of calculators he can buy.
So assuming he bought the entire 29 calculators he would've spent:
[tex]29 \times 3.85 = 111.65[/tex]
That leaves him with,
[tex]200 - 111.65 = 88.35[/tex]
Looking back at the prices i'm assuming there is no way he can reach 99 calculators with what he has left, so i will establish an equation that defines the number of calculators he can buy with the remaining £88.35.
Let c be the number of calculators he can still buy. Note that we are working in the 30-99 range so each calculator costs £3.65
[tex]88.35 = 3.65c[/tex]
[tex]c = \frac{88.35}{3.65} = 24.2[/tex]
So now we know he can still buy 24 calculators in addition to the 29 calculators, so in total he bought,
[tex]29 + 24 = 53[/tex]
Your answer would be 53 calculators.
What about the 0.2 remaining 'calculators',well that would be left over money which aren't sufficient to purchase an additional calculator+we were working with the 30-99 range meaning each one costs £3.65
[tex]0.2 \times 3.65 = 0.73[/tex]
So he bought 53 calculators and has 0.73£ remaining.
