Answer:

A) $\sqrt{8x/3}$

Step-by-step explanation:

$\sqrt{8x^{2} } /\sqrt{3x}$

$\sqrt{8x^{2}/{3x}$

$\sqrt{8x/3}$

Therefore, A is correct

A line passes through the origin and has a slope of -3 what is the equation of the line that is perpendicular to the first line

Marianna [84]

Answer: $y=\frac{1}{3}x+3$

Step-by-step explanation:

The equation of the line is Slope-intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

The slopes of perpendicular lines are negative reciprocal.

Then, if the slope of the first line is -3, the slope of the other line must be:

$m=\frac{1}{3}$

Substitute the point (3,4) into the equation and solve for b:

$4=\frac{1}{3}(3)+b\\ 4-1=b\\b=3$

Then the equation of this line is:

$y=\frac{1}{3}x+3$

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 2/3 when X=1/12means 2/3=1/12

K = 2/3÷1/12 = 8

Now that we know the value of K, we can use it to calculate the value of Y when X=1/2

Y = (8)(1/2) = 8/2=4

Y=4

Step-by-step explanation:

perimeter = semicircle (x2) + parallelogram side (x2)

= 1/2 π 12 (x2) + 15 (x2)

= 37.7 + 30

1. All of the variables below are directly proportional, write an equation linking them:

Natasha2012 [34]

Answer:

a. V = 3M

b. T = 5S

c. Y = 17x

d. H = 12M

e. P = 0.5N

Step-by-step explanation:

a. V= 12 when M =4

12/4 = 3, so in this case, V is 3 times M, that is, V = 3M

b. T= 5 when S=1

5/1 = 5, so in this case, T is 5 times S, that is, T = 5S

c. Y= 34 when x=2

34/2 = 17, so in this case, Y is 17 times x, that is, Y = 17x

d. H=48 when M=4

48/4 = 12, so in this case, H is 12 times M, that is, H = 12M

e. P= 5 when N=10

5/10 = 1/2 = 0.5, so in this case, P is half of N, that is, P = 0.5N
