No it is not a order pair. It’s not one because I did the work.

Answer: D.

Step-by-step explanation:

The distributive property is when you distribute the numbers to make solving easier. This means getting rid of the parentheses. SO your answer would either be A or D.

Your class hopes to collect at least 325 cans of food for the annual food drive. there were 135 cans donated the first week and

vampirchik [111]

They have collected $135+89=224$ cans until now. To equal 325, they need $325-224=101$ cans more.

Let C be the number needed to equate atleast 325.

$135+89+C\geq 325$

If we solve the inequality in part A, we can find minimum number of C to meet the goal of 325 cans.

$135+89+C\geq 325\\224+C\geq325\\C\geq325-224\\C\geq101$

So they need minimum 101 to complete the target and more than that to surpass.

ANSWER: 101 cans are needed to meet the goal and more than that to surpass the goal.

Solve: In 2x + In 2 = 0 DONE

pychu [463]

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

We can use some logarithmic rules to solve this easily.

Note: Ln means $Log_e$

Now, lets start with the equation:

$ln(2x) + ln(2) = 0\\ln(2x) = -ln(2)$

Writing left side with logarithmic base e, we have:

$Log_{e}(2x) = -ln(2)$

We can now use the property shown below to make this into exponential form:

$Log_{a}b=x\\means\\a^x=b$

So, we write:

$Log_{e}(2x) = -ln(2)\\e^{-ln(2)}=2x$

We recognize another property of exponentials:

$a^{bc}=(a^{b})^{c}$

So, we write:

$e^{-ln(2)}=2x\\(e^{ln(2)})^{-1}=2x$

Also, another property of natural logarithms is:

$e^{(ln(a))}=a$

Now, we simplify:

$(e^{ln(2)})^{-1}=2x\\(2)^{-1}=2x\\\frac{1}{2}=2x\\x=\frac{\frac{1}{2}}{2}\\x=\frac{1}{4}$

This is the answer.
