A.
250 cm2
B.
175 cm2
C.
800 cm2
D.
200 cm2
Answers
The area of the trapezium is 175 cm².
Option B is the correct answer.
What is a trapezium?It is a quadrilateral that has one pair of parallel sides and a height.
The area is calculated as 1/2 x the sum of the parallel sides x height.
Examples:
Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.
Area = 1/2 x (3 + 4) x 5
Area = 1/2 x 7 x 5
Area = 35/2 = 17.5 cm^2
We have,
Parallel sides are b and (c + b).
b = 15 cm
c + b = 5 + 15 = 20 cm
Height = a = 10 cm
Now,
The area of the trapezium.
= 1/2 x (sum of the parallel sides) x height
= 1/2 x (15 + 20) x 10
= 1/2 x 35 x 10
= 35 x 5
= 175 cm²
Thus,
The area of the trapezium is 175 cm².

to plot the point (-3,6), start at the origin and move three places down and six places right.
(theres no graph)
Answers
Answer: 3,3
Step-by-step explanation: the -3 is the x and 6 is the y so if u move 3 down on the y, it’s 3 and if you do 6 right, split the six, -3 plus 3 is 0 plus the remaining 3 is 3
Explanation: when you move 3 spaces down it’s on the y axis and it is negative. So we minus 3 from 6. This gets us 3 for the y coordinate. For our x coordinate it tells us to move right 6. Since right is the positive side it is -3+6. This will get us 3 for our x coordinate.

Answers
Answer:
1. x>18 2.x<-18 3. x>21 4. x>-7 5. x<2 6. x>-2 7. x<12 8.x<-6
Step-by-step explanation:
1. x/2>9 Pretend the inequality is an equal sign...
x/2=9 *2 x=18
If x>18; 20>18
20/2 = 10
10>9 so it works
If x<18 10<18
10/2 = 5
5<9 so it dosent
2. x/-2>9
x/-2=9
x=-18
If x>-18
0>-18
0/-2=0
0<9 so it doesent work.
x<-18; x=-20
-20/-2=10
10>9 So it works
3. x-7>14 --> x-7=14 ---> x=21
If x>21; x=22 --> 22-7=15; 15>14 (it works)
If x<21; x=20 --> 20-7=13; 13<14 (so it does not work)
4. x-7>-14 --> x-7=-14 --> x=-7
If x>-7; x=0 ---> 0-7=-7 --> -7>14 (so it works)
If x<-7; x=-10 ---> -10-7=-17 --> -17<14 (so it does not work)
5. 5x<10 --> 5x=10 --> x=2
If x>2 x=3 --> 5*3=15 15>10 (does not)
If x<2 x=1 --> 5*1=5 5<10 (works)
6. -5x<10 -5x=10 x=-2
If x<-2 x=-3 -3*5=-15 -15<10 (no)
If x>-2 x=0 5*0=0 0<10 (works)
7. x-3<9 x-3=9 x=12
if x>12 x=13 13-3=10 10>9

The perimeter of a rectangle is 86. The length of the rectangle is one more than twice the width. Determine the length and width of the rectangle.
Answers
There are two equation of the system
(1) The perimeter
2(w + l) = p
2(w + l) = 86
(2) The length and the width
2w = l + 2
From the second equation
2w = l + 2
l + 2 = 2w
l = 2w - 2
Subtitute l with 2w - 2 in the first equation to find the width
2(w + l) = 86
2(w + 2w - 2) = 86
2(3w - 2) = 86
6w - 4 = 86
6w = 90
w = 15
Now, find the length by subtituting w with 15
l = 2w - 2
l = 2(15) - 2
l = 30 - 2
l = 28
The dimension of the rectangle
length = 28 cm
width = 15 cm

Answers
Answer:
y=5(x-3)^2+2
Step-by-step explanation:
You plug the point into f(x)=a(x-3)^2+2... that already has already been solved for the vertex that you want. Then you swap it out for the solution you have solved for.
The required function is [tex]f(x)=5(x-3)^2+2[/tex].
Important information:
Vertex of a quadratic function is (3,2).The graph passes through the point (4,7).Quadratic function:The vertex form of a quadratic function is:
[tex]f(x)=a(x-h)^2+k[/tex]
Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is vertex.
Substitute [tex]h=3,k=2[/tex].
[tex]f(x)=a(x-3)^2+2[/tex] ...(i)
The graph passes through the point (4,7). Substitute [tex]x=4, f(x)=7[/tex] in (i).
[tex]7=a(4-3)^2+2[/tex]
[tex]7=a+2[/tex]
[tex]7-2=a[/tex]
[tex]5=a[/tex]
Substitute [tex]a=5[/tex] in (i).
[tex]f(x)=5(x-3)^2+2[/tex]
Therefore, the required function is [tex]f(x)=5(x-3)^2+2[/tex].
