Is it a function or no it’s not a function ?

Answer:

4th option

Step-by-step explanation:

x² - 2x - 3 = 0 ( add 3 to both sides )

x² - 2x = 3

using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 3 + 1

(x - 1)² = 4

By analyzing the parent function graph, we will see that:

Let's list each transformation and let's see which is the correct option for each one.

1) m(x) = -f(x).

This is a reflection over the x-axis, so, now the curve will open downwards. This means that now we have a decreasing function, so the correct option here is: "function decreases as x increases"

2) h(x) = f(x) + 2

This is a vertical translation of 2 units upwards. So it moves the whole graph 2 units upwards. Originally, you can see that in the left side we have an asymptote at y = 0, now that asymptote will be at y = 2.

So the correct option is: "asymptote of y = 2.

3) j(x) = f(x + 2)

This is a shift of 2 units to the left, notice that when we evaluate this in x =  0 we et:

j(0) = f(2) = 2^2 = 4

So the y-intercept os (0, 4).

4) g(x) = 2*f(x)

This is a vertical stretch of scale factor 2.

When we evaluate this in x = 0, we get:

g(0) = 2*f(1) = 2

So the y-intercept is at (0, 2).

Step-by-step explanation:

the hypotenuse of the right triangle is the diameter d of the circle

Using Pythagoras' identity in the right triangle

d² = 6² + 8² = 36 + 64 = 100 ( take square root of both sides )

d = [tex]\sqrt{100}[/tex] = 10

An expression is defined as a set of numbers, variables, and mathematical operations. The gross pay of Micha for the given month is $234.71. The correct option is  C.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that Micha is paid $8.25 per hour plus double time on holidays and makes an average of 8% commission on all golfing equipment sales, which is modeled by the expression 8.25(x) + 8.25(2)(y) + 0.08(z).

Now, if Micha worked 15 regular hours and 4 holiday hours and had $562.00 in golf equipment sales. Therefore, the value of x, y, and z is,

Regular hours, x = 15

Holiday hours, y = 4

Sales made in dollars, z = 562

Substitute the values in the given expression to get the gross pay of Micha in the given year,

Gross pay = 8.25(x) + 8.25(2)(y) + 0.08(z)

                 = 8.25(15) + 8.25(2)(4) + 0.08(562)

                 = $123.75 + $66 + $44.96

                 = $234.71

Hence, the gross pay of Micha for the given month is $234.71.

company N builds 100 wooden houses cut in half which is 50 brick houses, the ratio for company M is 5:3, 5x20=100  3x20=60.  60-50=10

A leather coat costs $120 and the sales tax is 7.25%. What is the TOTAL cost of the coat?

We need to take 7.25% out of 120.

[tex]7.25%[/tex] of [tex]120 = 8.7[/tex]

Now add the cost, and the tax.

[tex]120 + 8.7 = 128.7[/tex]

Put into currency form.

$[tex]128.70[/tex]

Final answer, 128 dollars, and 70 cents.

The total point is an illustration of arrangements

There are 6 different numbers that could the total points scored by Tim

The different number (n) that can represent the total point is calculated as:

n = 2 points + 3 points + 1

Remove the units

n = 2 + 3 + 1

Evaluate the sum

n = 6

Hence, there are 6 different numbers that could the total points scored by Tim

Step-by-step explanation:

given

(2x + 5)(2x - 1) ← expand using FOIL

(a)

= 4x² - 2x + 10x - 5 ← collect like terms

= 4x² + 8x - 5

(b)

using the method of completing the square on

4x² + 8x - 5 ← factor out 4 from the 1st 2 terms

= 4(x² + 2x) - 5

to complete the square

add/ subtract ( half the coefficient of the x- term )² to x² + 2x

= 4(x² + 2(1)x + 1 - 1) - 5

= 4(x + 1)² - 4 - 5
