The base of an isosceles triangle is parallel to the x-axis. The y-axis passes through an end point of the base. If the endpoint
AnnyKZ [126]
The first x coordinate is given by 0 and the second one is given as j. So the length of the base is j. (Sometimes in math they give letters rather than numbers. And since you know it is an isosceles then the other vertex should be at x-coordinate half j or j/2.

The national weather service reports the daily temperature in degrees
kobusy [5.1K]

Answer:

C =\frac{5}{9}(F - 32)

Step-by-step explanation:

Given

F = 1.8C + 32

Required

Solve for C

F = 1.8C + 32

Subtract 32 from both sides

F-32 = 1.8C + 32-32

F-32 = 1.8C

Divide both sides by 1.8

\frac{1}{1.8}(F - 32)  = C

Express the decimal as fraction

\frac{1}{18/10}(F - 32)  = C

\frac{10}{18}(F - 32)  = C

Simplify

\frac{5}{9}(F - 32)  = C

C =\frac{5}{9}(F - 32)

If a line passes thru the points (4,5) and (2,9) the slope of this line is
Allisa [31]

Answer:

m=-2

Explanation:

If a line passes through the points (4,5) and (2,9): to calculate the slope, use the formula below:

\text{Slope,m}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}

Substituting the points, we have:

\begin{gathered} m=\frac{9-5}{2-4} \\ =\frac{4}{-2} \\ =-2 \end{gathered}

The slope of this line is​ -2.
