Answer:
3. Since it asked us to write question 3 in the from y=mx + c
m is the gradient
c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).
Now to find m.
Pick points on the line
Say (1,6) and (2,3)
Gradient = m = y2 - y1/(X2 - X1)
x1 = 1
y1 =6
x2 = 2
y2 = 3
Substituting into that formula
m = 3 - 6/2 - 1
m= -3/1
m= -3.
Since we've gotten what we need
y=mx + c
Y= -3x + 9.
4. 4x + 2y = 12
Rearranging by making y subject to suit the eqn...y=mx + c
you have
m is the gradient and c is the intercept.
2y = -4x + 12
Divide through by 2
y= -2x + 6
y=mx + c
By comparing...
m==gradient = -2
c== Intercept = 6
5). Doing the same thing we did above
-6x + 3y =21
Making y subject
3y = 6x + 21
Divide through by 3
y= 2x + 7
y=mx + c
m==gradient =2
c==Intercept =7.
Hope this helps.
Have a great day!

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?
Answers
Answer:
Step-by-step explanation:
You haven't given the choices but I believe the equation below could represent the area of the circle:
(pi ~ 3.14) * (18)^2
The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Kenna's bedroom is 12 feet long by 8 feet long. Her parents have agreed to buy new carpet for the entire bedroom.The carpet costs $15 per square meter. What will be the total cost of the new carpet? 1 foot = 0.305 meter
A. $439.20
B. $54.90
C. $133.96
D. $91.50
Answers
Answer:
C. $133.96
Step-by-step explanation:
Convert units:
12 · 0.305 = 3.66 m
8 · 0.305 = 2.44 m
Find the area of the room:
3.66 m · 2.44 m = 8.9304 m²
Find the cost:
8.9304 · 15 = 133.96
12ft = 3.66 sq meters
8ft = 2.44 sq meters
3.66 x 2.44 = 8.9304
8.9304 x 15 = 133.956

Answers
Answer:
[tex]6\frac{1}{2}[/tex]
Step-by-step explanation:
When given the following problem:
[tex]7\frac{1}{7}-\frac{9}{14}[/tex]
Convert the first mixed number to an improper fraction. This can be done by multiplying the "number" part of the mixed number by the denominator of the fraction, the number under the fraction bar. Then add the result to the numerator.
[tex]\frac{50}{7}-\frac{9}{14}[/tex]
To perform this operation, one must ensure that both denominators have the same value. Multiply the numerator and denominator for the first fraction by (2), so that the denominators of both fractions is (14),
[tex]\frac{100}{14}-\frac{9}{14}[/tex]
Perform the operation, subtract one numerator from the other, leave the denominators the same,
[tex]\frac{91}{14}[/tex]
Simplify, divide the numerator by (14) (the denominator), write the whole part as the "number" part of the mixed number. Then write the remainder on top of the fraction bar.
[tex]6\frac{7}{14}[/tex]
Reduce, divide the numerator and denominator by a common fraction,
[tex]6\frac{1}{2}[/tex]

Corners: (2c+100) x 8Non- corners: 10(c+100) x 4 x210 x 10x 100 x 2 =200002. Middle Layers:
Corners: (c+100)x 4 x 10Non- Corners: 100 x 10 x 4 x 10 =40000So,
(2c+100) x 8 + 10(c+100) x 4 x2 + (c+100)x 4 x 10 + 20000 + 40000
16c + 800 + 80c + 8000 + 40c + 400 + 60000
136c + 72800

connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?
Answers
Answer:
96
Step-by-step explanation:
Step 1: Multiply 60% by 40
40 x .60 = 24
24 is 60 percent of 40
Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.
100 ÷ 25 = 4
Step 3: Multiply 4 by 24
4 x 24 = 96
The answer is 96 :)
