What is the equation of this line? A: y=-3/2x B: y=2/3x C: y=-2/3x D: y=3/2x

creativ13 [48]

Answer:

b) y = 2/3x

Step-by-step explanation:

Slope (m) formula: $\frac{y_2-y_1}{x_2-x_1}$

I will be using (3,2) and (-3,-2) to find the slope:

$m=\frac{-2-2}{-3-3}\\m=\frac{-4}{-6} \\m = \frac{2}{3}$

$y = mx + b\\y = \frac{2}{3}x+b$

(3,2)

$y = \frac{2}{3}x+b\\\\2 = \frac{2}{3}(3)+b\\\\2 = 2+b\\-2 -2\\\\0=b$

$y=mx+b\\\\y = \frac{2}{3}x+0\\\\y = \frac{2}{3}x$

Hope this helps!

The cheerleaders are practicing a dance routine in which all 36 of them need to be in a triangular formation. there will be two

dimulka [17.4K]

If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.

Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.

Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum

So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and

1+3+5+7+9+11 = 36

which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.

Donald Trump wants to build a 100 meter high tower as quickly as possible. He has unlimited resources and an unlimited budget an

Sladkaya [172]

It will take 100 weeks to build the tower.

Since Donald Trump wants to build a 100 meter high tower as quickly as possible with blocks that are 100 meters long and 100 meters wide, but only 1 meter tall, and using special lifters, putting one stack on top of another stack takes one week regardless of how high the stacks are, to determine what is the shortest amount of time (weeks) that it will take to build the tower, the following calculation must be performed:

Time per block x total blocks = Total time
1 week x 100 = X
100 weeks = X

Therefore, it will take 100 weeks to build the tower.

1. The rule is that for something to be a function, one input(x-value) can ONLY HAVE ONE output(y-value). If one input has more than one output, it is not a function. Your answer is #1 because you can only have 1 output

2. Since you've been given the input -> x = -10, substitute/plug it into the equation to find the output:

$y=\frac{3}{2} x+6$ Plug in -10 into "x"

$y=\frac{3}{2} (-10)+6$

y = -15 + 6

y = -9 Your answer is #2

This is a geo question i do not understand someone please help me

rewona [7]

Y= 3/5x+1. remember RISE OVER RUN from algebra? the formula is y=mx+b. b is the y intercept, where the line in the graph touches the y axis. your teacher has made it easy and plotted 3 points on the graph. pick any two. it went up 3 times, and to the right 5 times. also, it is a positive slope because from left to right, it goes UP. i hope i helped!! :)
