Answer:
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation we must first find the slope of the line
Slope of the line using points (−2, 6) and (2, 14) is
Now we use the slope and any of the points to find the equation of the line.
Equation of the line using point ( - 2, 6) and slope 4 is
We have the final answer as

Answer:
a) 8cm
b) 19.8cm
Step-by-step explanation:
The key to these types of questions is to keep proportions in mind.
To solve the first question, you want to find the proportion of the smaller triangle to the bigger triangle. The length of AE is 6cm, but the length of AD is (6+4) = 10cm. So the proportion of the bigger triangle to the smaller triangle is 10/6. So to find the lengths of the sides of the bigger triangle, we want to keep this number in mind.
The BE side is parallel to CD, so we have to use length of BE multiplied by the proportion in order to get the length of CD.
CD = 4.8 * (10/6) = 8
CD = 8cm
For the second question, you use the same concept to find all the other side lengths. The only one you need left for the shape EBCD is side BC. Do the same thing you did before, take the length of the side of the smaller triangle that corresponds with side AC on the bigger triangle. In this case, it's AB, which is 4.5cm. Multiply this by 10/6 to get AC.
AC = 4.5 * (10/6) = 7.5
AC = 7.5
But we're not done. We just found the length of AC, but we need the length of BC to calculate the perimeter. To do this, we want to take the length of AC - the length of AB.
7.5 - 4.5 = 3
So the length of BC is 3cm. Now, to find the perimeter, just add all the sides of EBCD together.
4.8 + 4 + 8 + 3 = 19.8cm.
Hope this helps.
You're given the conversion formula of 1 yard = 3 feet and 1 foot = 12 inches so let's use that.
For red you're given three yards so because 1 yard = 3 feet, then you have
3 feet + 3 feet + 3 feet = 9 feet ( or 3ft * 3)
Now, to get inches, you multiply 9 by 12 to get 108 inches.
Since each bow requires 6 inches of ribbon you divide 108 by 6.
- Number of red bows: 18
- Inches of ribbon: 108
Yellow
Given: 54 inches
to convert to feet, you divide by 12 : 54/12 = 4.5 and to find yards you divide by 3: 4.5/3 = 1.5
to find the number of bows you divide 54 by 6: 9 bows
-Number of yellow bows: 9
-Yards of yellow ribbon: 1.5
Blue
Given: 24 bows
Because there's 6 inches for every bow 24*6 = 144 inches of ribbon
Convert to yards: 144/12 = 12 feet / 3 ft = 4 yards
-Inches of blue ribbon:144
-Yards of blue ribbon: 4
Answer:
I would say parallelogram. So the rectangle still fits but more shapes can be applied.
