What are the intercepts of this line?

olga_2 [115]

Answer:

x-intercept is -1; y-intercept is 0.5.

Step-by-step explanation:

The x-intercept is relatively easy to read off. It's the x-value where the graph crosses the x-axis, and here is (-1,0).

The y-intercept is best estimated as (0,+0.5).

The correct answer is the 3rd one on the list.

the length of a rectangle is 5 inches longer than twice the width and the area is 12 inches squared. Let l represent the length

svet-max [94.6K]

Answer:

Length = 8 inch , Width = $\frac{3}{2}$ , This equation models the situation

Step-by-step explanation:

Given as ;

The Area of Rectangle is 12 inches²

The Length of Rectangle is 5 inches longer than twice the width

Let The Length = L inches

The Width = W inches

According to question ,

L = 5 + (2 × w )

∵ The Area of Rectangle = Length × width

Or, 12 inches² = [ 5 + (2 × w ) ] × w

Or, 12 inches² = 5 w +2 w²

Or, 2 w² + 5 w - 12 = 0

Or, 2 w² + 8 w -3 w - 12 = 0

Or, 2 w (w +4) - 3 (w + 4) = 0

I.e (w + 4) ( 2 w - 3) = 0

So , w = -4 , and w = $\frac{3}{2}$

∴ Length = 5 + (2 × w ) =

Length = 5 + (2 × $\frac{3}{2}$ )

so , L = 5 + 3 = 8

Hence Length = 8 inch , Width = $\frac{3}{2}$ This equation models the situation Answer
