What must you do to the first inequality to get to the second inequality? A. N 4 <5;n<20 b. − n 4 <5;n>−20 A. A. Add

adell [148]

A. You have two inequalities:

$\dfrac{n}{4}$
$n$

If you multiply the first inequality by positive number 4 (multiplying inequality by positive number doesn't change the inequality sign), then you get the inequality

$4\cdot \dfrac{n}{4}$

B. You have two inequalities:

$-\dfrac{n}{4}$
$n>-20.$

If you multiply the first inequality by negative number -4 (multiplying inequality by negative number changes the inequality sign), then you get the inequality

$-4\cdot \left(-\dfrac{n}{4}\right)>-4\cdot 5,\\ \\n>-20.$

Answer: option D.

In properties of logarithms, what is log2 25?

spayn [35]

$log_a(b)=c$ $log_a(b)=c$ translates to

$a^c=b$ $a^c=b$
let's say it equals y

$log_2(25)=y$ $log_2(25)=y$
trsnaltes to
$2^y=25$ $2^y=25$
doesn't help us
we can also translate it to
$log_2(5^2)$ $log_2(5^2)$ or $2log_2(5)$ $log_2(5^2)$

The midpoint of line MN is P(5,5). One of the end points in M(-4,2). Find the coordinate of endpoint N.

Greeley [361]

-4 + x    2 + y
------- = 5 and   ------ = 5
2       2

so x = 10 + 4 = 14 and y = 10 - 2 = 8

endpoint N = (14,8)

Given that m∠ABD = 84° and m∠BAC = 37°, what is the m∠ACD?

stich3 [128]

Answer: 84°

Step-by-step explanation:

Pardon my drawing, I know it;s not prefect, and I'm not sure how to draw a figure on Brainly, but this is the best I can do. For this problem, it is easier to draw it out so you can see that the angles look like. Just pretend the lines are filled in, and this is a perfect parallelogram.

A ________________ C

/ /

B /_______________/ D

As you can see, the angles given in the problem gives us a parallelogram. Since we know m∠ABD is 84° and m∠BAC is 37°, we know that m∠ACD is 84°. If you draw diagonal lines, ∠ABD and ∠ACD are vertical angles. Vertical angles are congruent. Therefore, m∠ACD is 84°.
