Which line is parallel to y= -52 + 6 and passes through (4, -2)?
Alexxandr [17]

Answer:

\[y=-5x+18\]

Step-by-step explanation:

Given that the line is parallel to \[y = -5x + 6\]

Hence the slope of the line is given by -5

Hence the equation of the required line can be represented by \[y = -5x + c\]

This line passes through (4,-2). Substituting:

\[-2 = -5 * 4 + c\]

=> \[-2 = -20 + c\]

=> c = 20-2 = 18

So the required equation of the line is given by : \[y = -5x + 18\]

From the given options, option 3 is the correct one.

Suppose that y varies inversely with x, and y=3 when x=4.
yawa3891 [41]

When y varies inversely as x it can be expressed as follows:

\frac{1}{x}\text{ }\propto\text{y}

If we write the general equation for this

y=\frac{A}{x}

When y=3 and x=4 we can calculate de value of A

\begin{gathered} x=4 \\ y=3 \\ 3=\frac{A}{4} \\ A=4\cdot3 \\ A=12 \end{gathered}

Then the equation that describes an inverse variation between x and y is_

y=\frac{12}{x}

What number must you add to complete the square?<br> x^2 + 12x = 16
dmitriy555 [2]

Answer: B. 36

The complete square is (x+6)^2. It's missing the third term, which is 36 because 6 x 6 is 36.
