Emily is a songwriter who collects royalties on her songs whenever they are played in a commercial or a movie. Emily will earn $50 every time one of her songs is played in a commercial and she will earn $150 every time one of her songs is played in a movie. Emily's songs were played on 3 times as many commercials as movies and her total earnings on the royalties from all commercials and movies were $600. Graphically solve a system of equations in order to determine the number of commercials, x,x, and the number of movies, y,y, on which Emily's songs were played.

Answer:

$39.95 + $1.99x

Step-by-step explanation:

Cost of shoes = $39.95

Cost per pair of socks = $1.99

Number of socks pairs purchased = x

Total amout spent = (cost of shoes + cost of x pairs of socks)

Cost of x pairs of socks = $1.99 * x = $1.99x

Total amount spent = $39.95 + $1.99x

Answer:

$39.95 + $1.99x

The value of expression after subtraction is,

⇒ - 0.177

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Expression is,

⇒ 0.123 - 0.3

Now, We can simplify the expression by subtracting as;

⇒ 0.123 - 0.3

⇒ - 0.177

Thus,  The value of expression after subtraction is,

⇒ - 0.177

Answer:

k=1/4

Step-by-step explanation:

x² - 5kx+ k=0  ....(1)

suppose 2 roots: a and 4a

(x-a)(x-4a)=0

x² - 5ax + 4a² = 0 ....(2)

compare (1) and (2): -5a = -5k              a=k

4a² = k                4a² = a   (substitute)

a(4a-1) = 0

a = 0 or a = 1/4        (if a=0   k=0 and x=0 is not the solution)

a = 1/4      k = 1/4

(a₂ = 1/4 * 4 = 1)

Answer:

k = 1/4.

Step-by-step explanation:

Let the roots be  r and 4r   and using the fact that sum of the roots = -b/a and product = a/c, we have:

r + 4r = -(-5k)

r*4r = k

5r = 5k

4r^2 = k

From the 3rd equation:

r = k, therefore:

4k^2 = k

4k = 1

k = 1/4.

Answer:

The starting height of the raiders is 39 meters.

Step-by-step explanation:

Physically speaking, a free fall motion is an uniformly accelerated motion due to gravity. Mathematically, speaking the equation of motion for the height of an object under free fall is a second order polynomial (quadratic function).

Let [tex]h(t) = -9.8\cdot t^{2}-5\cdot t + 39[/tex] be the height of the riders, in meters, the starting height is the height evaluated at [tex]t = 0\,s.[/tex] Hence, we proceed to the determined the required data by direct evaluation:

[tex]h(0) = -9.8\cdot (0)^{2}-5\cdot (0) +39[/tex]

[tex]h(0) = 39[/tex]

The starting height of the raiders is 39 meters above the ground.

Answer:

(x,y)=(4,6)

Step-by-step explanation:

3x+4y=36

y=-1/2 x+8

step 1: substitute the value of y

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

step 2: solve equation for x

[tex]3x+4(-\frac{1}{2}x+8)=36[/tex]

3x-2x+32=36

x+32=36

x=36-32

x=4

step 3: substitute the value of x

[tex]y=-\frac{1}{2} (4)+8[/tex]

Step 4: solve equation for y

[tex]y=-\frac{1}{2} (4)+8[/tex]

y=-2+8

y=6

there for the answer is

(x,y)=(4,6)
