Answer:

x = 3

Step-by-step explanation:

All three vertical lines are parallel and that makes the angle with measure of 67 degrees and the angle with measure represented by 23x - 2 are alternate and equal:

67 = 23x - 2 add 2 to both sides

69 = 23x divide both sides by 23

3 = x

If y varies inversely with x, and y=8 when x=10 find x when y=4

lana66690 [7]

Answer:

x = 4

Step-by-step explanation:

Given y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 8 when x = 10

k = yx = 8 × 10 = 80

y = $\frac{80}{x}$ ← equation of variation

When y = 4, then

4 = $\frac{80}{x}$ ( multiply both sides by x )

4x = 80 ( divide both sides by 4 )

x = 20

If f(x)=log10x, what is the approximate value of y in the equation 10^y=5?

Simora [160]

$\bf log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\
-----------------------------\\\\
10^y=5\implies log(10^y)=log(5)\implies ylog(10)=log(5)\\\\\\ y=\cfrac{log(5)}{log(10)}\\\\
-----------------------------\\\\
\textit{Logarithm Change of Base Rule}\\\\
log_{{ a}}{{ b}}\implies \cfrac{log_{{ c}}{{ b}}}{log_{{ c}}{{ a}}}\\\\
-----------------------------\\\\
y=\cfrac{log(5)}{log(10)}\iff y = log_{10}(5)\iff y=log(5)$
