Consider functions f, g, and h below.
shutvik [7]
We evaluate f (x) between [0, 2]
 We have then:
 f (x) = x2 + 2x +3
 f (0) = (0) 2 + 2 (0) +3 = 3
 f (1) = (1) 2 + 2 (1) +3 = 6
 f (2) = (2) 2 + 2 (2) +3 = 11
 We observe that the function g between [0, 2] is between 4 and 7
 We observe that the function h is a linear equation whose rate of change is constant and equal to three.
 Answer:
 
from least to greatest, by the rate of change of functions over the interval [0, 2] we have:
 
g, h, f

Someone please explain this step by step:
Volgvan

Answer:

  13

Step-by-step explanation:

Perhaps the most straightforward way to find the value of the given function is to first solve the equations for x and y. The results can be substituted into your expression to find the value you want.

__

<h3>solving the system</h3>

We notice the y-coefficients are opposites, so we can eliminate the y-variable by adding the equations.

  (2x -y) +(x +y) = (3) +(1)

  3x = 4 . . . . . . simplify

  x = 4/3 . . . . . divide by 3

The value of y can be found from the second equation:

  4/3 +y = 1 . . . . substitute for x

  y = -1/3 . . . . . . subtract 4/3

<h3>expression value</h3>

The value of 8x-7y is found by substituting the x- and y-values into this expression:

  8(4/3) -7(-1/3) = 32/3 +7/3 = 39/3 = 13

The value of 8x-7y is 13.

_____

<em>Additional comment</em>

You can also work out what combination of the two equations will give 8x -7y. That turns out to be 5 times the first minus 2 times the second:

  5(2x -y) -2(x +y) = 5(3) -2(1)

  10x -5y -2x -2y = 15 -2

  8x -7y = 13

__

The coefficients 5 and -2 are found by solving the system of equations ...

  a(2x -y) +b(x +y) ≡ 8x -7y   ⇒   {2a +b = 8, -a +b = -7}

What is x and what converse is used to find x
mrs_skeptik [129]

Answer:

4

Step-by-step explanation:

the third angle of the inner triangle is defined by using the rule that the sum of all angles in a triangle must be 180 degrees. let's call this angle a

180 = 48 + 16x + a

132 - 16x = a

and then we know that both angles, 28x and a together must also be 180, as they are complementing each other to cover the whole top of the base line.

so,

28x + 132 - 16x = 180

12x = 48

x = 4
