What is the slope of the line passing through the points (0, −5) and (4, 2)?

liraira [26]

$(0,-5) \\
x_1=0 \\ y_1=-5 \\ \\
(4,2) \\
x_2=4 \\ y_2=2 \\ \\
\hbox{the slope } = \frac{y_2-y_1}{x_2-x_1}=\frac{2-(-5)}{4-0}=\frac{2+5}{4}=\frac{7}{4}$

The slope is 7/4.

What is the exact value of x in the exponential equation 2^5x − 57 = 43?

katovenus [111]

Start by getting the term with the exponent on one side
$2^{5x}=100$

take the log of both sides
$log 2^{5x} =log100$

There is a log rule that says we can bring down the exponent
$5xlog2=log100$

Solve for x
$5x= \frac{log100}{log2}$
5x=6.64

answer: x=1.33
