If f(x) = 7(x - 2) + 4(x + 1), what is f(2)?<br><br> A. 9 B. 10 C. 12 D. 11
KatRina [158]

Answer:

C) 12

Step-by-step explanation:

These type of questions is basically asking you to replace x with 2. f(x) is the same thing as y = but inside the f(x) is the value of x. So in this case, the numerical value of x is 2. All we need to do is replace x with it's numerical value, 2, and solve the equation.

y=7(2-2) + 4(2+1)\\y=7(0) + 4(3)\\y = 12

Find the distance between (-7, -2) and (11,3). Write your answer to one decimal.<br> Your answer
scoray [572]

Answer:

<h3>The answer is 18.7 units</h3>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7, -2) and (11,3).

The distance between them is

d =  \sqrt{( { - 7 - 11})^{2}  +  ({ - 2 - 3})^{2} }  \\  =  \sqrt{ ({ - 18})^{2}  + ( { - 5})^{2} }  \\  =  \sqrt{324 + 25}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \\  =  \sqrt{349}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 18.681541692... \:  \:  \:  \:  \:

We have the final answer as

<h3>18.7 units to the one decimal place</h3>

Hope this helps you
