bija089 [108]

Answer:

11 minutes

Step-by-step explanation:

Because she types only 140 words in 4 minutes so if you add

140+140=280

140/4 you get 35

so every minute she types in 35 words. So multiply

11 times 35 and you exactly get 385.

Determine which equation is written in function form:
Mila [183]

<em>Greetings from Brasil... </em>

A 1st degree function can be written in two ways:

F(X) = AX + B

or

Y = AX + B

note that F(X) = Y

So, looking at the alternatives in the question, only Y = 7X/3 - 8 is equivalent to Y = AX + B, where:

A = 7/3

B = - 8

then

\large{\boldsymbol{\mathbf{Y = \frac{7X}{3}-8\Leftrightarrow Y=AX+B}}}   <em>a function of the 1st degree</em>

answer:

<h2>Y = (7/3)X - 8</h2>
