Ok so all we need to do is find the length of a single concert, 

8hr/3 concerts = 2.6666666 length of a concert, 

then to find the length of 4 converts just multiply by 4, 

10.666666... hours

What is the equation of the line, in standard form, that passes through (4, -3) and is parallel to the line whose equation is 4x
Serggg [28]

Answer:

The equation of this line would be 4x + y = 13

Step-by-step explanation:

In order to find this equation we must first find the slope of the original line. To do this, we solve the original equation for y.

4x + y - 2 = 0

4x + y = 2

y = -4x + 2

The original slope (the coefficient of x) is -4, which means the new slope will also be -4 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line. Just plug in the numbers and solve for the coefficient.

y - y1 = m(x - x1)

y + 3 = -4(x - 4)

y + 3 = -4x + 16

4x + y + 3 = 16

4x + y = 13

Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel.
tia_tia [17]

Answer: the equations are

k = d + 33

k - 2 = 4(d-2)

Step-by-step explanation:

Let the present age of Kevin be represented by k

Let the present age of Daniel be represented by d

Kevin is 33 years older than Daniel. This means that the expression for their current age is

k = d + 33

Two years ago, Kevin was 4 times as old as Daniel. This means that 2 will be subtracted from their present ages to depict two years ago. Therefore, Two years ago for Daniel will be d-2

Two years ago for Kevin will be k - 2

Remember that Kevin was 4 times as old as Daniel two years ago, it becomes

k - 2 = 4(d-2)

Find the cosine of ∠W.
allochka39001 [22]

Answer:  8/17

Explanation:

We'll need the pythagorean theorem to find the missing side length.

a^2 + b^2 = c^2\\\\15^2 + b^2 = 17^2\\\\225 + b^2 = 289\\\\b^2 = 289 - 225\\\\b^2 = 64\\\\b = \sqrt{64}\\\\b = 8

Now we can compute the cosine ratio.

cos(angle) = adjacent/hypotenuse

cos(W) = VW/UW

cos(W) = 8/17

Getting 10% a month is the best option if she put $500 in.  That would be $50 the first month. $55 the second month etc. -- which would be more than the $500 in answer 1.
