2x=10y Determine the constant of proportionality. Assume that y represents all of the outputs and x represents the inputs

Mathematics
1 answer:
Art [367]3 years ago
3 0

Answer:

a = 0.2

Step-by-step explanation:

Let y = ax be a linear equation, where x is the input variable and y is the output variable, then "a" is the proportionality constant between x and y.

To find the proportionality constant of the given equation, we must take it to the form y = ax.

We have:

2x = 10y

We divide both sides of the equation by 10.

0.2x = y

y = 0.2x.

Then the constant of proportionality is:

a = 0.2

Answer:

If 4/8 cm = 25 miles

If 4.8 cm = 240 miles

If 48 cm = 2400

Step-by-step explanation:

4/8 x 50

4.8 x 50

48 x 50

I was unsure if there was a fraction bar or decimal. or if it was 48 so I gave all possibilities.

A 30ft electric line is suspended between the tops of two 20ft electric poles on level ground. The lowest point of the line is 5
Lilit [14]

Answer:

There is no distance between them

Step-by-step explanation:

For a 30 ft electric line to be placed between two 20ft electric poles, it would take 15 ft of the electric line to go down to about 5 ft above the ground and another 15 ft of the line to go to the top of the second electric pole. This means that a total of 30ft (15 ft + 15 ft) electric line would be needed which is all the cable we have.

For this to be possible then the poles must be adjacent to each other (i.e. no distance between them).

Find the equation of the straight line through (–2, 3) perpendicular<br> to 2x + y =8
Thepotemich [5.8K]

Answer:

y = \dfrac{1}{2}x + 4

Step-by-step explanation:

The equation of a line in slope-intercept form is

y = mx + b

We need to find the slope, m, and the y-intercept, b.

The line we need is perpendicular to the line 2x + y = 8.

<em>The slopes of perpendicular lines are negative reciprocals.</em>

We solve the given equation for y to find the slope of the given line.

2x + y = 8

y = -2x + 8

The given line has slope -2.

The negative reciprocal of -2 is 1/2.

Our line has slope, m = 1/2.

Now we have

y = 1/2 x + b

Now we use the given point, (-2, 3), for x and y, using x = -2, and y = 3, and we solve for b.

y = 1/2 x + b

3 = 1/2 * (-2) + b

3 = -1 + b

4 = b

b = 4

Now we have

y = 1/2 x + 4

Answer: y = \dfrac{1}{2}x + 4
