egment AB falls on line 2x − 4y = 8. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?

jolli1 [7]

Answer:

The line segments AB and CD are perpendicular to each other.

Step-by-step explanation:

Segment AB falls on line 2x − 4y = 8.

Rearranging the equation into slope-intercept form we get, ............. (1)

Therefore, slope of the line segment AB is

Now, the segment CD falls on line 4x + 2y = 8.

Rearranging the equation into slope-intercept form we get, ............. (2)

Therefore, the slope of the line segment CD is, N = - 2

So, M × N =

Hence, we can conclude that the line segments AB and CD are perpendicular to each other

(4,9),(1,6) find the slope of the line that passes through each pair of points

nikklg [1K]

Answer: The slope is 1

Step-by-step explanation:

y2-y1/x2-x1 is the equation to find slope

plug in the numbers and you get: 6-9/1-4

that equals -3/-3 which can be simplified to 1

$0.\overline{36} = \dfrac{36-0}{99} = \dfrac{36}{99} = \dfrac{4}{11}\\\\\\0.3\overline{6}= \dfrac{36-3}{90} = \dfrac{33}{90} = \dfrac{11}{30}\\\\\\0.36 = \dfrac{36}{100} = \dfrac{9}{25}$

1. Cindy did an experiment. She started out with 700 bacteria cells. She found that the growth rate of the bacteria cells was 4.

Brums [2.3K]

Answer:

This is an exponential function of the form $y=a(b^x)$
We will use the following
y for the number of bacteria at a given time
x for the time
a for the starting number of bacteria, which is 700
b for the base of the exponent
so lets find b, we need the following:
r, which will be our rate, which is 4.3% or 0.043, so

$b=1+r\\b=1+0.043\\b=1.043$
With this info, let's substitute, and get the equation as the answer: $y=700(1.043^x)$
Put that into desmos, (I attached a screenshot for you)
