Answer:

  • equation: y = x+3
  • inequality: y < x+3

Step-by-step explanation:

The slope of the line is 1 unit of rise for 1 unit of run, so ...

  m = rise/run = 1/1 = 1

The y-intercept is 3 grid lines above the x-axis, so is (0, 3).

Then the equation of the line is ...

  y = 1x +3

The inequality has that line as a boundary, but the y-values on the line are not part of the solution space. Only y-values below the line (less than those on the line) are in the solution. The inequality is ...

  y < x +3

3/4 + 3/9 how do i do this
Artist 52 [7]

Answer:

13/12

Step-by-step explanation:

Well, you can't add it yet because the denominators don't match. We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change as well. So, multiply 3 by 8, and get 24. Since 4 is evenly divided by 8, we can multiply just one term to get a common denominator. Multiply 3 by 2, and get 6, then we multiply 4 by 2 and get 8. Since our denominators match, we can add the numerators. So now your answer should be 9/8.  Well guess what... IT IS THE ANSWER! You can't reduce it anymore so 9/8 is your answer! Hope this helped!

For a particular angle theta, the cosine function f(x) = a cos b(theta) has the following values within one cycle of the functio
Anton [14]
For function f(x)=a\cos b\theta we have that f(0) =4,\ f( \frac{\pi}{2} )=-4,\ f(\pi)=4. This means that period of cosine function is π. Then from the formula for period T= \frac{2\pi}{b} you obtain that \pi= \frac{2\pi}{b} and b=2. 

So, the function is f(x)=a\cos 2\theta. If f(0)=4, then a\cos0=4 and, respectively, a=4.
Answer: f(x)=4\cos 2\theta.
