Answer:

(0,3) and (4,-5)

Step-by-step explanation:

f(x) just means y and so does g(x).

Both equations are equal to y. So they are equal to each other. Set equal to each other to solve. After finding x, don't forget to find the y that goes with each x. See image.

The values of the solution of the given system of equation are (0,3) and (4,-5)

<h3>How to find the solution to the given system of equation?</h3>

For that , we will try solving it first using the method of substitution in which we express one variable in other variable's form and then you can substitute this value in another equation to get a linear equation in one variable.

If there comes a = a situation for any a, then there are infinite solutions.

If there comes wrong equality, say for example, 3=2, then there are no solutions, else there is one unique solution to the given system of equations.

We have been given the system of equation,

f(x) = -x^2 + 2x + 3

g(x) = -2x + 3

Both equations are equal to y.

y = -x^2 + 2x + 3\\y= -2x + 3

So they are equal to each other.

by solving both the equation

-x^2 + 2x + 3 = -2x + 3\\\\ x^2 -4x = 0\\

x(x-4) = 0

Therefore, x = 4 and x= 0

To find the value of y,

y = -2x + 3

y = -2(4) + 3

y = -5

y = -2x + 3

y = -2(0) + 3

y = 3

The opposite angles equal each other, so X and Z are equal
 using that we solve for x by setting them equal:

6x-60 = 2x+68

subtract 2x from each side:

4x -60 = 68

add 60 to each side:

4x = 128
 divide both sides by 4
x = 128/4
x = 32

now we know x so we can solve everything else by replacing x with 32

WY = 3x+5 = 3(32)+5 = 96+5 = 101

angle Z = 2x+68 = 2(32)+68 = 64+132

the answer is C

Let e f (x) = x2 – 2x - 4 What is the average rate of change for the quadratic function from X = -1 tox to x = 42 Enter your ans
sammy [17]

Answer:

The average rate of change of the given function

A(x) =  1

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given function f(x) = x² - 2x -4

And given that x = a = -1 and  x=b = 4

The average rate of change of the given function

A(x) = \frac{f(b)-f(a)}{b-a}

<u><em>Step(ii):-</em></u>

f(x) = x² - 2x -4

f(-1) = (-1)² - 2(-1) -4 = 1+2-4 = -1

f(4) = 4² -2(4) -4 = 16 -12 = 4

The average rate of change of the given function

A(x) = \frac{f(b)-f(a)}{b-a}

A(x) = \frac{4-(-1)}{4-(-1)} = \frac{5}{5} = 1

<u><em>final answer:-</em></u>

The average rate of change of the given function

A(x) =  1

Transformation involves changing the position of a shape.

The transformation from \triangle ABC to \triangle A'B'C' is 90 degrees clockwise rotation

Using the coordinates of A and A', we have:

A= (-6,3)

A'= (3,6)

Notice that the x-coordinate is <em>negated </em>and then <em>swapped </em>with the y-coordinate.

i.e.

(x,y) \to (y,-x)

The transformation of a point from <em>(x,y) to (y,-x)</em> is a 90 degrees clockwise rotation.

Hence, the transformation from \triangle ABC to \triangle A'B'C' is 90 degrees clockwise rotation
