150 - 1/2s = 120 + 1/4s

agasfer [191]

Answer:

s=40

Step-by-step explanation:

Combine s and 1/2.

150−s/2=120+1/4s

Combine 1/4and s.

150−s/2=120+s/4

Move all terms containing s to the left side of the equation.

150−3s/4=120

Move all terms not containing s to the right side of the equation.

−3s/4=−30

Multiply both sides of the equation by −4/3.

−4/3 x (−3s/4)=−4/3 x−30 => S=40

If log6⁡⁡3+log6⁡⁡72=x, what is the value of x?

soldi70 [24.7K]

$\bf \textit{logarithm of factors}\\\\
log_{{ a}}(xy)\implies log_{{ a}}(x)+log_{{ a}}(y)
\\\\\\
\textit{Logarithm Change of Base Rule}\\\\
log_{{ a}}{{ b}}\implies \cfrac{log_{{ c}}{{ b}}}{log_{{ c}}{{ a}}}\\\\
-------------------------------\\\\
log_6(3)+log_6(72)=x\implies log_6(3\cdot 72)=x\implies log_6(216)=x
\\\\\\
\cfrac{log(216)}{log(6)}=x\impliedby \textit{using the change of base rule}$

recall that, log <--- with no apparent base, implies base10, so you can just plug that in your calculator

for the change of base rule, it doesn't really matter what base you use, so long is the same above and below, it just so happen, that we used base10 in this case, but could have been anything, same result.

What is the slope of a line perpendicular to the line y=2x+5 ?What is the slope of a line perpendicular to the line y=2x+5 ?

enot [183]

Answer:

$-\frac{1}{2}$

Step-by-step explanation:

Hi there!

In the given equation $y=2x+5$ , the slope of the line is 2.

Perpendicular lines always have slopes that are negative reciprocals, like negative "flipped" fractions.

Example: The negative reciprocal of $\frac{3}{1}$ (which is the same as 3) is $-\frac{1}{3}$ .

Example 2: The negative reciprocal of $-\frac{4}{3}$ is $\frac{3}{4}$ .

Using this logic, the negative reciprocal of 2, or $\frac{2}{1}$ , is $-\frac{1}{2}$ . Therefore, the slope of a line perpendicular to the line $y=2x+5$ is $-\frac{1}{2}$ .

I hope this helps!
