Answer:

Y  =  (  -1) | 8 | 17 | 26 | 35|

Step-by-step explanation:

y = 9x + 8  \\ \\  \\ x = ( - 1) \\ y = 9( - 1) + 8 \\ y =  - 9 + 8 =  - 1 \\  \\ x = 0 \\ y = 9(0) + 8 \\ y = 0 + 8 = 8 \\  \\ x = 1 \\ y = 9(1) + 8 \\ y = 9 + 8 = 17 \\  \\ x = 2 \\ y = 9(2) + 8 \\ y = 18 + 8 = 26 \\  \\ x = 3 \\ y = 9(3) + 8 \\ y = 27 + 8 = 35 \\  \\  \\  Y  =  (  - 1) | 8 | 17 | 26 | 35|

The following table shows the length and width of two rectangles:
zhannawk [14.2K]

Answer:

10x - 8 or 2( 5x - 4)

Step-by-step explanation:

Perimeter of a rectangle = 2( Length + Width)

<u>Rectangle A </u>

Length = x + 8,

Width  = x - 1

Perimeter_A = 2((x + 8) + ( x - 1))\\\\

                 = 2(x + 8 + x - 1) \\\\= 2(2x + 7)\\\\=4x + 14

<u>Rectangle B</u>

Length = 4x + 5

Width = 3x - 2

Perimeter _B= 2((4x + 5) + (3x-2))\\\\

                 =2(4x + 5 + 3x - 2)\\\\=2(7x + 3)\\\\=14x + 6

Perimeter_B - Perimeter_A = (14x +6)-(4x + 14) \\\\

                                       =14x + 6 - 4x - 14\\\\=10x -8\\\\or \\\\=2(5x - 4)

What's the value of x? (Hint: it's not 7) and please explain
tekilochka [14]

Hey there!

4x + 7 + 35 = 90°

4x + 42 = 90°

SUBTRACT 42 to BOTH SIDES

4x + 42 - 42 = 90 - 42

CANCEL out: 42 - 42 because it give you 0.

KEEP: 90 - 42 because it help solve for the x-value.

NEW EQUATION: 4x = 90 - 42

SIMPLIFY IT!
4x = 48°

DIVIDE 4 to BOTH SIDES

4x/4 = 48/4

CANCEL out: 4/4 because it give you 1

KEEP: 48/4 because it give you the x-value

NEW EQUATION: x = 48/4

SIMPLIFY IT!

x = 12

Therefore, your answer is: x = 12


Good luck on your assignment & enjoy your day!
