Look for patterns in the input and output.

For example
0-0
1- 2
2-4
3-6

So the pattern you see here is increase in 2 each time. So the pattern rule can be that you multiply the input by 2 to get the output.

Find the equation for the line that passes through the point (2, -3), and that is parallel to the line with the equation x - 3y
Vadim26 [7]

Step-by-step explanation:

the slope of a line is the factor of x, when the equating looks like

y = ...

so,

x - 3y = 3

x = 3y + 3

3y = x - 3

y = 1/3 x - 1

so, the original slope is 1/3.

a parallel line has the same slope.

having a specific point we can use the point-slope form as equation :

y - y1 = m(x - x1)

with m being the slope, and (x1, y1) being a point on the line.

y - -3 = 1/3(x - 2)

y + 3 = 1/3(x - 2)

simplified that is

y + 3 = 1/3 x - 2/3

y = 1/3 x - 2/3 - 3 = 1/3 x - 2/3 - 9/3 = 1/3 x - 11/3 =

= 1/3 × (x - 11)

80 km is 9% of what distance??
Karolina [17]

<u>Answer:</u>

  • 80 km is 9% of 888.89 km.

<u>Step-by-step explanation:</u>

<u>We know that:</u>

  • 80 km = 9%

<u>Work:</u>

  • 80/9 km = 1%
  • => 80/9 x 100 = 100%
  • => 8000/9 = 100%
  • => 888.89 km = 100% (Rounded to nearest hundredth)

Hence, <u>80 km is 9% of 888.89 km.</u>

Hoped this helped.

One number is 32 less.than another. If the sum of the two numbers is 94 , find the two numbers.
Ratling [72]

Answer:

let the number be x, so that the two numbers are x and x - 32 The first number is x = 62.

The second number is x - 32 = 62 - 32 = 30.

Step-by-step explanation:

x + x - 32 = 92

or, 2x = 92 + 32

or, 2x = 124

or, x = 124/2 = 62
