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!

Since b + 30 = 90, we know b = 60.
That means a = 60
a = 60
b = 60
c = 30
Answer:
a) 60°
b) 60°
c) 30°
Step-by-step explanation:
Get 60 by subtracting 30 from 90 because the angle is a right angle. Since b is identical to a and also is a right triangle, it will also be 60. Get c as 30 by looking at its vertical angle across from it.
A small theater sold 36 adult tickets. The ratio of adults to children was 4:3. How
many child tickets were sold?
Answers
Answer:
27
Step-by-step explanation:
if the theater sold 36 adult tickets and the ratio of adult to children was 4:3, we already know that they sold more adult tickets than children tickets. to turn 36 into 4, we divide 36/4 to get 9, 4*9=36 so we have to do this to the 3, 3*9=27. 36:27 is equal to 4:3.

Answer:
x = 52
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles of a triangle
x+72 = 34+90
x +72 =124
Subtract 72 from each side
x = 124-72
x =52
Answer:
x = 52 degrees
Step-by-step explanation:
Let's first focus on the angle x + 72. Immediately adjacent to x + 72 is angle RQS. These two angles are "straight" in that they lie immediately adjacent to one another and add up to 180 degrees. Then angle RQS can be expressed as
180 degrees - (x + 72 degrees), or 108 - x degrees.
The three interior angles of the triangle must add up to 180 degrees. Hence
108 - x degrees + 34 degrees + 90 degrees = 180 degrees, and so:
108 - x + 34 = 90
This yields x = 52 degrees.

Mora wants to tile the surface of a rectangular storage case that is 24 inches long, 16 inches wide, and 8 inches tall. If she uses all the green tiles, how many tiles would she need?
Answers
Answer:
1408 square tiles
Step-by-step explanation:
She is basically tiling the surface area of a rectangular prism that is 24 by 16 by 8 inches long. A rectangular prism has 6 sides total. Here, the sides are:
24 by 16
24 by 16
16 by 8
16 by 8
24 by 8
24 by 8
So basically, Each length is multiplied by another length 2 times each. We need to add all of these lengths together:
(24 * 16) + (24 * 16) + (16 * 8) + (16 * 8( + (24 * 8) + (24 * 8) = (384 + 384) + (128 + 128) + (192 + 192) = 768 + 256 + 384 = 1408

Mona used 22 tiles to surface the rectangular storage.
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given that, a rectangular storage case is 24 inches long, 16 inches wide, and 8 inches tall, Mona is using green tile of dimension 8 in x 8 in, we need to find how many did she used to surface the storage,
So, finding the same, we will divide the surface area of storage by area of the tile,
The surface area of a rectangular storage = 2(lw + wh + lh), where l = length, w = width and h = height.
Area of a square tile = side²
No. of the tiles used = 2(24·16+16·8+8·24) / 8²
= 22
Hence, Mona used 22 tiles to surface the rectangular storage.

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]
The answer is 6 1/2
