Answer:

perpendicular

Step-by-step explanation:

First we need to dtemine the slopes of the line

For line 1

L1: (-4, 6) (-3,-1)

m1 = y2-y1/x2-x1

m1= -1-6/-3+4

m1 = -7/1

m1 = -7

For line 2:

L2: (8,9) (15, 10)

m2 = 10-9/15-8

m2 = 1/8

Take their product

m1 * m2 = -7 * 1/7

m1m2 = -1

Since the product of their slopes is -1, hence they are perpendicular

What is 2 to the power of 4/3 equal to

Reika [66]

Answer:

<h2>Eksponent</h2>

$\sf{ \large{ \boxed{ \red{ {a}^{ \frac{n}{m} } = \sqrt[m]{ {a}^{n} } } } }}$

$\sf{ {2}^{ \frac{4}{3} } }$

$= \sqrt[3]{ {2}^{4} }$

$= \sqrt[3]{2 \times 2 \times 2 \times 2}$

$= \boxed {\bold{\sqrt[3]{16}(c.) }}$

There are 250 votes tallied in a school election with 3 candidate:A, Candidate B, and Candidate C. If 150 of the votes are for c

Tanya [424]

The answer is 75 and here's why.

Let's figure out the amount of remaining votes to prove this.

250 total votes - 150 votes for candidate a = 100 votes.

minus ↑ sign

Candidate B received 25% of the votes, so let's find 25% of 100

100 * 0.25 = 25 votes

Candidate B only got 25 votes (that's kinda sad, poor guy)

100 - 25 votes = the # of votes candidate C got

Candidate C got 75 votes!

There are 12 boys and 15 girls in your class for new students three boys and one girl join your class what is the ratio of the c

Finger [1]

Before the new kids the ratio of girls to boys is 15:12 because there are 15 girls and 12 boys now you can simplify by dividing 15 by 3 and 12 by 3 to get 5:4 as your simplified ratio. As far as after the new kids. Since there is 1 new girl you do 15+1 to get 16 and there are 3 new boys so you do 12+3 to get 15 now 16:15 is already in simplest form so your answer is:

Before: 15:12 simplified as 5:4
After 16:15
