1/3(y+2)+3x=7x Plz help!

Distribute the 1/3 to the y and the 2
So... (1/3)*y and (1/3)*2

(y/3)+(2/3)+3x=7x

Now subtract 3x from both sides

(y/3)+(2/3)=4x

To get rid of the 3 on the bottom of the fractions, you can multiply both sides by 3 so they cancel out.

y+2=12x
Subtract 2 from both sides to get an equation of
y=12x-2

Given that (1,9) is on the graph of f(x), find the corresponding point for the function 2/3 f(x)

GrogVix [38]

Answer:

(1,6)

Step-by-step explanation:

If "(1, 9) is on the graph of f(x),"

then (1, [2/3][9]) is on the graph of the function y = (2/3)f(x). This works out to (1, 6).

determine the radius of the cone ,if the voulime of the cone is 125 cm to the power of 3 and the height of the cone is 12cm. Rou

Salsk061 [2.6K]

For this case we have that by definition, the volume of a cone is given by:

$V = \frac {1} {3} * \pi * r ^ 2 * h$

Where:

r: It is the radius of the cone

h: It is the height of the cone

According to the statement data we have:

$h = 12 \ cm\\V = 125 \ cm ^ 3$

Substituting in the formula:

$125 = \frac {1} {3} * \pi * r ^ 2 * 12$

We cleared the radius:

$3 * 125 = \pi * r ^ 2 * 12\\\frac {3 * 125} {12 \pi} = r ^ 2\\9.9522 = r ^ 2\\r = \pm \sqrt {9.9522}$

We choose the positive value:

$r = 3.1547$

We round and we have that the radius of the cone is:

$r = 3.16 \ cm$

ANswer:

$r = 3.16 \ cm$

What is the measure of

Zolol [24]

Answer:

pretty sure its 55° because the total should be 180* and I know that C is a right angle aka 90° and 90 + 35 = 125 and 180-125=55
