Answer:
-5 is the y intercept.
Step-by-step explanation:
Ok, lets do the steps in order.
1) Make a point-slope form equation.
We know that the format of it is y - y1 = slope(x - x1), so we know have to substitute our information in the equation.
y - 5 = 5(x - 2)
2) Convert our point-slope form equation into slope intercept form, and solve for the y-intercept.
y = slope(x) + b... right? So we now have to do math.
Distribute the right side of the equation to get :
y - 5 = 5x - 10
Now cancel out the -5, and then subtract on both sides.
y = 5x - 5
And -5 is your y intercept :)
Hope this helps! Mark me brainliest :)

Part IV: Last year's winner (9 points) Your sponsor will need to know how your average speeds compare to the speeds of past winners. In Part IV, you'll find out how to calculate boat speeds in knots (nautical miles per hour).
1. What was the winning time of last year's race for your city and boat? (2 points, one for each leg)
2. Do you know how fast last year's winner was traveling? (2 points)
3. What information do you need to know to calculate last year's winning speed? Remember, the distance traveled (length of the course) is equal to the rate (boat's speed) times the time. (2 points) A nautical mile is 6076 feet. A speed of one nautical mile per hour is a knot. In the next two questions, you will convert a speed in feet per minute to knots.
4. If you travel 1000 feet in 5 minutes, what is your speed in feet per minute? (1 point)
5. What is your speed in knots? Hint: Use the number of minutes in an hour to convert the speed to feet per hour. Then use the number of feet in a nautical mile to convert feet per hour to knots. (2 points: 1 point for finding the speed in feet/hr. 1 point for converting to knots)
Using the information given in the table, and the speed - time relationship, the solutions to the exercises goes thus :
Using the information given in the table :
1.) The winning time for last year's race will be the lowest time on the table. Using the winning time column, the winning time for each city is :
Sydney = 14.75 minutes San Francisco = 16.25 minutes Mykonos = 25.5 minutes2.)
The winning time of past winners cannot be determined as the exact distances of each city isn't given.
3.)
The information required to calculate speed is distance and time ;
Speed = (distance / time)4.)
Distance = 1000 feets Time = 5 minutesDistance = 1000/5 = 200 ft/min
5.)
Speed in Knots ;
Speed in feets per hour
60 minutes = 1 hour200 ft/ min × 60/1 hour = 12000 feets per hour
Speed in nautical mile per hour
1 nautical mile = 6076 feets(12000 ft/hr) × (1/6076)feets = 1.975 nautical miles per hour
Therefore, speed in knots is 1.975 knots.

Work out the height of this triangle with base,
b
= 8.6mm and area,
A
= 256.28mm2.
Answer:
[tex]59.6[/tex] mm
Step-by-step explanation:
We know that the base times the height divided by two is the area, so we have that [tex](8.6*h)/2=256.28[/tex].
We can multiply both sides by [tex]2[/tex] to get [tex]8.6*h=512.56[/tex].
Lastly, we divide by [tex]8.6[/tex] on both sides to get [tex]h=512.56/8.6[/tex].
This simplifies to [tex]\boxed{h=59.6}[/tex] mm!

Step-by-step explanation:
[tex](12x - 41) + 5x = 180[/tex]
[tex]12x + 5x = 180 + 41[/tex]
[tex]17x = 221[/tex]
[tex] \frac{17x}{17} = \frac{221}{17} [/tex]
[tex]x = \frac{221}{17} [/tex]
[tex]x = 13[/tex]
[tex](12 \times 13 - 41) + 5(13) = 180[/tex]
[tex]115 + 65 = 180[/tex]
[tex]180 = 180[/tex]
[tex]vertical \: angles[/tex]
[tex](12x - 41) = 5y[/tex]
[tex]12 \times 13 - 41 = 5y[/tex]
[tex]115 = 5y[/tex]
[tex] \frac{115}{5} = \frac{5y}{5} [/tex]
[tex]y = \frac{115}{5} [/tex]
[tex]y = 23[/tex]
[tex]5y=12x-41[/tex]
[tex]5×23=12×13-41[/tex]
[tex]115=115[/tex]
We can use the two terms in x to find the value of x.
Angles on a line have a sum of 180°
⇒ (12x -41)° + 5x° = 180°
⇒ (12x + 5x -41)° = 180°
⇒ 17x° = 180 + 41°
⇒ x = 13
We can use the same principle of angles to find y
5x° + 5y° = 180°
since x = 13; 5(13) + 5y = 180
5y = 115
y = 23
∴ x = 13 & y = 23PLEASE HELPP

4x+3-x=12x-15
Answer:
2
Step-by-step explanation:
4x+3−x=12x−15
Combine 4x and −x to get 3x.
3x+3=12x−15
Subtract 12x from both sides.
3x+3−12x=−15
Combine 3x and −12x to get −9x.
−9x+3=−15
Subtract 3 from both sides.
−9x=−15−3
Subtract 3 from −15 to get −18.
−9x=−18
Divide both sides by −9.
x= –18÷–9
Divide −18 by −9 to get 2.

The length of one of the parallel sides is 8 cm and the height is 6 cm. Find the length of the other parallel side.
Answer:
come here if you want to see
The length of the other parallel side is 10 cm.
Trapezium is a quadrilateral (has four sides and four angles) with a pair of parallel sides. The area (A) of a trapezium is given by:
A = (1/2)(a + b)h
where a and b are the length of the parallel sides, h is the height of the trapezium
Given A = 54, a = 8 cm, h = 6 cm, hence:
54 = (1/2)(8 + b)6
8 + b = 18
b = 10 cm
The length of the other parallel side is 10 cm.
