No, (2,2) is not solution of y < 4x - 6

Step-by-step explanation:

To solve above linear problem, we use standard method of  Back- Substitution.

First of all, A point (2,2) only becomes solution of equation, if it satisfies equation y < 4x - 6.

Here, the  y < 4x - 6  seems to be like a linear equation.

In this Equation, using  Back- Substitution method,

Point (2,2) : first digit 2 corresponds to x- coordinate and second digit 2 corresponds to y-coordinate.

           y < 4x - 6.....(1)     \\\         x= 2        .....(2)       \\\       y= 2        .....(3)

By putting value of x and y in equation (1),

Equation becomes,

        2 <  4 \times 2  - 6

       2 < 8       -  6

       2 <  2      .... not true mathematically.

Finally, the result came is not true. Therefore, (2,2) is not solution for equation

y < 4x - 6

The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.

<h3>How to Evaluate a Function?</h3>

We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:

  • h(t) = 0 (height of the ground is 0)
  • t = seconds the waste takes to height the ground
  • Initial height = 400 feet

Plug in the values into the equation of the function

0 = -16t² + 400

Solve for t

0 - 400 = -16t²

-400 = -16t²

-400/-16 = t²

400/16 = t²

√(400/16) = t

20/4 = t

5 = t

t = 5

The number of seconds it takes is: 5 seconds.

Write the expression in standard form. <br> 2/2-15i
nlexa [21]
Standard form is a+bi

so get rid of that deonmenator

\frac{2}{2-15i}
multiply it by\frac{2+15i}{2+15i}
result is
\frac{4+30i}{4+225} = \frac{4+30i}{229}= \frac{4}{229} + \frac{30i}{229}

answer is \frac{4}{229} + \frac{30i}{229}
