Uhhhhhh how do i do this????

Troyanec [42]

Answer:

Step-by-step explanation:

To find the equation of the line represented by the table, you can use the two-point form of the equation for a line:

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (60 -40)/(10 -5)(x -5) +40

y = 20/5(x -5) +40 . . . . simplify a bit

y = 4x -20 +40 . . . . . . . eliminate parentheses

y = 4x +20 . . . . . . . . . . . simplify to slope-intercept form

This tells you the y-intercept of the table function is +20. The graph tells you the y-intercept is +1.

The distance between +1 and +20 is 19.

The dimensions of an iPhone are x – 2 and x + 3. If the area of an iPhone is 14 square inches, find the dimensions of the iPhone

QveST [7]

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.
