122. Write the equation of the line that is

Marina CMI [18]

When a line is given in the form

$y=mx+q$

The slope of the line is m. So, in this case, the slope of $y=x-5$ is 1.

Given a slope $m$ , you find the slope of a perpendicular line $m'$ by imposing

$m\cdot m' = -1$

So, if the given line has slope 1, a perpendicular line has slope $m'$ given by

$1 \cdot m' = -1$

and thus $m'=-1$

So, we want a line with slope -1 and passing through (12,-1). Using the fomula

$y-y_0=m(x-x_0)$

we get

$y-(-1)=-1(x-12) \iff y+1=-x+12 \iff y=-x+11$

C. Use the activity series of metals to predict the products of the following single-replacement

vesna_86 [32]

Answer: NiCl2 + Fe

Iron is above nickel in the activity series, so iron will replace nickel like this:

NiCl2 + Fe → FeCl2 + Ni

Cu(OH)2 is insoluble, so it will form a precipitate.

The temperature in Armand's town in the morning was -3.6 degrees Fahrenheit. The temperature in the afternoon was 0 degrees Fahr

Daniel [21]

Answer: The overall change was $3.6\textdegree F$ from the morning to the afternoon.

Explanation:

Since we have given that

The temperature in Armand's town in the morning is given by

$-3.6\textdegree F$

The temperature in Armand's town in the afternoon is given by

$0\textdegree F$

Change in the temperature from the morning to the afternoon is given by

$0-(-3.6)=3.6\textdegree F$

So,the overall change was $3.6\textdegree F$ from the morning to the afternoon.
