For which function is the ordered pair (2, 12) not a solution?

1 answer:

6 0

The x-coordinate is 2 and y-coordinate is 12.

Substitute 2 into x then check if y is equal to 12.

D is the answer since y = (2) - 10 = -8, not 12.

Answer:

y = 4x-9

Step-by-step explanation:

16x-4y-36 = 0

-4y = -16x+36(subtract 16x from both sides and add 36)\

y = 4x-9(divide both sides by -4)

The answer is B. Line.

That is because a point is just a dot and lane is represented by a rectangle or a parallelogram.

Hope this helps :)

Answer:

The dimensions of the iphone are 2 inches by 7 inches.

Step-by-step explanation:

Given that,

The dimensions of an iPhone are x – 2 and x + 3.

The area of an iphone is 14 sq inches

We need to find the dimensions of the iPhone. It is in the shape of a rectangle. Its area is given by :

$A=l\times b\\\\(x-2)(x+3)=14\\\\x^2-2x+3x-6=14\\\\x^2+x-6-14=0\\\\x^2+x-20=0\\\\x^2+5x-4x-20=0\\\\x(x+5)-4(x+5)=0\\\\(x-4)(x+5)=0\\\\x=4\ and\ x=-5$

Neglecting negative value

First dimension = (x-2) = (4-2) = 2 inches

Other dimension = (x+3) = (4+3) = 7 inches

Hence, the dimensions of the iphone are 2 inches by 7 inches.
