Marisol is painting on a canvas that has an area of 180 square inches. The length of the painting is 11/4 times the width. What

Alona [7]

Notice the picture below, see the length "l"?

well $\bf Area=l\times w\qquad 
\begin{cases}
l=\frac{11}{4}w\\
Area=180
\end{cases}\\\\
-----------------------------\\\\
thus
\\\\
180=\cfrac{11}{4}w\times w$

solve for "w", to find the width,

what's the length? well, l = 11/4 w

Which pair of expressions represents inverse functions?

faust18 [17]

In this question , we have to find, which option represents inverse functions.

Let's check out option b

Let it be y

So we have

$y = \frac{x+3}{4x-2}$

Switching x and y and solving for y,

$x = \frac{y+3}{4y-2}$

Performing cross multiplication

$4xy -2x = y+3$

Combining like terms

$y(4x-1) = 3+2x$

$y = \frac{2x+3}{4x-1}
\\
f^{-1} (x) = \frac{2x+3}{4x-1}$

Which is same as of the other function.

So correct option is b .

Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 6) = 0

Eddi Din [679]

ANSWER

b=11

EXPLANATION

The given quadratic equation is

$(2x - 1)(x + 6) = 0$

We expand to get:

$2 {x}^{2} + 12x - x - 6 = 0$

We simplify further by combining the x terms.

$2 {x}^{2} + 11x - 6 = 0$

This is the standard form.

Comparing to

$a{x}^{2} + bx + c= 0$

We have b=11
