Answer:-The function g(x) is defined for all real numbers x.

-The maximum value of the range is 4.

-The maximum value of the domain is 3.

-The range of g(x) is {y| –1 < y ≤ 4}.

-The domain of g(x) is {x| –4 < x ≤ 3}.

This trapezium is drawn on a centimetre grid.<br> Find the area of the trapezium.
sleet_krkn [62]

Answer:

A = 21 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = \frac{1}{2} h (b₁ + b₂ )

where h is the height between bases and b₁, b₂ are the parallel bases

Here h = 3, b₁ = 9, b₂ = 5 , then

A = \frac{1}{2} × 3 × (9 + 5) = 1.5 × 14 = 21 cm²

babunello [35]
Let 1 angles be x, then its supplement is 180-x

x+x+12=180
2x=168
x=84

angles are 84 and 96

The length of a rectangle is 4 centimeters less than twice its width. The perimeter of the rectangle is 34 cm. What are the dime
weqwewe [10]
Answer is length = 10 cm; width = 7 cm


Let L=length and W=Width.

The length of a rectangle is 4 centimeters less than twice its width. 

This would mean that:
L= 2w-4

To find the perimeter of a rectangle you add all sides together. This would be shown as 2L+2W

Therefore, 2L+2W= 34

Since this equation has two unknowns, you cannot solve it; but we know that L=2W-4

So if we substitute that into the equation of the perimeter, you would get:
2(2W-4)+2W=34.

This only has one unknown so we can solve it. Here are the steps:

2(2W-4)+2W=34
4W-8+2W=34
6W-8=34
6W=42
W=7

Now that we know what W is we can work out L.

L=2W-4
L=14-4
L=10

So W=7 and L=10!

This shows that the length is 10cm and the width is 7cm.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
vladimir1956 [14]

Answer:

6)  C

7) A

8) D

9) B

Step-by-step explanation:

when the sign is < or  > then the point is clear point(white)

when the sign is ≤ or ≥ then the point is solid ( black)

6) 4y+3≤y+6

4y-y≤6-3

3y≤3

y≤3/3

y≤1  (C)

<u>                                                                                                    </u>

7) -2y>2 ( wen sign is negative you flip the sign from> to <)

y<-2/2

y<-1  (A)

---------------------------------------------------------------------------------------

8) y/3<-1 ⇒ y<-3  the sign is < means it is clear and on -3 (D)

--------------------------------------------------------------------------------------

9) 3y≤2y+3

3y-2y≤3

y≤3 ( B)
