The equation for the situation is 5x+6(0.95)=11.95

The solution to the equation is x=1.25

First, you must set up the equation.

5x+6(0.95)=11.95

Then, you must simplify the terms.

5x+5.7=11.95

Next, subtract 5.7 on both sides.

5x=6.25

Finally, divide 5 on both sides

x=1.25

If x+2y=3 and xy=2 show that x³+8y³+9=0​
kicyunya [14]

Step-by-step explanation:

<u>Given</u>

  • x + 2y = 3 and xy = 2
  • show that x³ + 8y³ + 9 = 0​

<u>Solution in steps:</u>

  • (x + 2y)³ = 3³
  • x³ + 3x²(2y) + 3x(2y)² + (2y)³ = 27
  • x³ + 6x(xy) + 12y(xy) + 8y³ = 27
  • x³ + 8y³ + 6(x + 2y)xy = 27                    ⇒  Substitute values
  • x³ + 8y³ + 6*3*2 = 27
  • x³ + 8y³  + 36 - 27 = 0
  • x³ + 8y³  + 9 = 0

Can someone please help with this q^q
Mazyrski [523]

Answer:

y = -\frac{3}{4} sin(\frac{2}{3}x)

Step-by-step explanation:

First determine whether it is a sine function or a cosine function. Since

sin(x) = 0 at x = 0 and we see indeed that the value of the function is 0 at x = 0 it must be a sine function

The general equation of a sine function is a sinbx

where a is the amplitude. The amplitude is one-half the difference between the lowest and highest values in the graph.From the graph we can see that the highest value is 3/4 and lowest is -3/4 so the amplitude = 1/2 (3/4 + 3/4) = 3/4

If the amplitude were positive, the function would be increasing at (0,0) and going up to its amplitude value. However we can see that the function is decreasing at (0,0 ) and goes down to -3/4. Therefore the amplitude a has a negative sign so a = -3/4

To compute b, note that the period of the function ie where it finishes a full cycle is 3π since the function at that x value repeats itself. The relationship between b and the period is 2π/b = 3π in this particular case

This gives b = 2/3

So a = -3/4, b = 2/3 and the equation is y = -\frac{3}{4} sin(\frac{2}{3}x)
