Does the equation 7x-4y=0 represent a direct variation? what is the constant of variation?

Mathematics

Naddika [18.5K]4 years ago
4 0

Answer:

yes, k = \frac{7}{4}

Step-by-step explanation:

The equation representing direct variation is

y = kx ← k is the constant of variation

rearrange 7x - 4y = 0 into this form

subtract 7x from both sides

- 4y = - 7x ( divide both sides by - 4 )

y = \frac{7}{4} x ← in standard form

with k = \frac{7}{4}

WORTH 10 POINTS! 1)susan can type 4 pages of text in 10 minutes.Assuming she types at a constant rate,write the linear equation
Minchanka [31]
1) pages per minute is the rate. the rate is the slope pages/minutes = .4
y=.4x or y=2/5(x)
2)birdhouses per day is the slope. = .6
y=.6x or y=3/5(x)
3) miles per hour is the slope. 500/8=62.5
y=62.5x
4) square feet per minute is the slope. 40/9 =4.444444444
y=4.4444444444x or y=40/9(x)
5)miles per minutes is the rate. 5/41 is the slope. 
y=5/41(x)
6) the rate is square feet per minute. 450/30=15
y=15x
