Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )

m = $\frac{-5-9}{-2-(-2)}$ = $\frac{-14}{-2+2}$ = $\frac{-14}{0}$

Since division by zero is undefined then the slope is undefined

First off, there are 5 shirts. 2 shirts take 28 seconds. If you divide 28 by 2, that means that each shirt takes 14 seconds.

5x14=70

Therefore, it takes 70 seconds to fold 5 shirts.

Given the function f(x) = The quantity of 2x minus 5, divided by 3 , which of the below expressions is correct? (1 point) f−1(x)

Anuta_ua [19.1K]

Answer:

$f^{-1}(x)$ =the quantity of 3x plus 5 divided by 2

Step-by-step explanation:

We are given that a function $f(x)=\frac{2x-5}{3}$

We have to find the correct expression

Suppose y= $\frac{2x-5}{3}$

$3y=2x-5$

$3y+5=2x$

$x=\frac{3y+5}{2}$

Therefore, $f^{-1}(x)=\frac{3x+5}{2}$

Answer: $f^{-1}(x)$ =the quantity of 3x plus 5 divided by 2

Answer:

x = 5.5

Step-by-step explanation:

Given 2 secants intersecting the circle from a point outside the circle then

The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is

x(x + 14) = 6(6 + 12)

x² + 14x = 6 × 18 = 108 ( subtract 108 from both sides )

x² + 14x - 108 = 0 ← in standard form

with a = 1, b = 14 and c = - 108

Using the quadratic formula to solve for x

x = ( - b ± $\sqrt{b^2-4ac}$ ) / 2a

= ( - 14 ± $\sqrt{14^2-(4(1)(-108)}$ ) / 2

= ( - 14 ± $\sqrt{196+432}$ ) / 2

= ( - 14 ± $\sqrt{628}$ ) / 2

x = $\frac{-14-\sqrt{628} }{2}$ or x = $\frac{-14+\sqrt{628} }{2}$

x = - 19.5 or x = 5.5 ( to 1 dec. place )

However x > 0 ⇒ x = 5.5
