Find the slope of a line perpendicular to y = 3x + 7

Mathematics
1 answer:
Vikki [24]3 years ago
4 0

Answer:

-1/3

Step-by-step explanation:

The slope of the line has the form y = mx + b where m is the slope. Here the slope is m = 3. A line perpendicular to it will have a negative reciprocal slope. The negative reciprocal of 3 is -1/3.

Answer: Table H would be the correct answer;

The rule of a function is that for each x-value given there can't be more than 1 y-value

<u>In Table F:</u>

x = -13, then y = -2

x = -13, then y = 0

x = -13, then y = 5

x = -13, then y = 7

For the x-value -13, there are 4 different y-values, so <em>it's not a function.</em>

<u>In Table G:</u>

x = -6, then y = 3

x = -1, then y = -1

x = -1, then y = 5

x = 10, then y = -9

For the x-value -1, there are 2 different y-values, hence <em>this isn't a function.</em>

<u>In Table H:</u>

x = 1, then y = 4

x = 3, then y = 4

x = 7, then y = 4

x = 12, then y = 4

For each x-value, there is only 1 y-value, so <em>this is a function.</em>

<u>In table J:</u>

x = -9, then y = -7

x = -2, then y = -5

x = 0, then y = 0

x = 0, then y = 6

For the x-value 0, there are 2 different y-value therefore <em>this isn't a function</em>

Hope this helps!

Since he starts with (10x+7) dollars and is buying two pairs of jeans that each cost (4x-5) dollars you should subtract the cost of the jeans from his starting amount.

(10x+7)-2(4x-5)=
10x+7-8x+10=
2x+17

A rectangular pool is 18 meters wide and 24 meters long. If you swim diagonally across the pool, how many meters would you be sw
Zanzabum
Using the Pythagorean theorem, the diagonal measure is found as
  √((18 m)² +(24 m)²) = √(324 +576) m = √900 m
  = 30 m

You would be swimming 30 meters.
