Answer:

4.5 hours

Step-by-step explanation:

So, let's write a function p(x) which represents the total cost.

Let's let x represent the amount of hours.

The cost of a piece is a constant 10.

And there is a $8 fee per hour. In other words:

[tex]p(x)=8x+10[/tex]

We spent a total of $46.

So, substitute in 46 for p(x) and solve for x:

[tex]46=8x+10[/tex]

Subtract 10 from both sides:

[tex]36=8x[/tex]

Divide both sides by 8:

[tex]x=36/8[/tex]

Reduce:

[tex]x=4.5[/tex]

So, we spent about 4.5 hours.

Answer:

y = 4(x - 2)² + 48

Step-by-step explanation:

Given

y = 4x² - 16x + 64

Using the method of competing the square

Factor out 4 from 4x² - 16x

y = 4(x² - 4x) + 64

add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = 4(x² + 2(- 2)x + 4 - 4 ) + 64

   = 4(x - 2)² - 16 + 64

    = 4(x - 2)² + 48

y = 4(x - 2)² + 48

Step-by-step explanation:

Answer:

y = 9

Step-by-step explanation:

Given

6.4x + 2.8y = 44.4 ← substitute x = 3 into the expression

6.4(3) + 2.8y = 44.4

19.2 + 2.8y = 44.4 ( subtract 19.2 from both sides )

2.8y = 25.2 ( divide both sides by 2.8 )

y = 9

Answer:it’s 1/5

Step-by-step explanation:

Answer:

1/5

Step-by-step explanation:

Answer:

Step-by-step explanation:

As seen from the first given equation: x + 1/x = 2

If we think of x as x/1 instead then we get:

x/1 + 1/x = 2.

To combine the fractions we multiply the top and bottom of the first one (x/1)  by x to get x^2/x so both have the same denominator so we can combine them which gives us:

(x^2+1)/x=2

Move x to the other side and we get:

x^2+1=2x

Move it back and we get a quadratic equation of

x^2 - 2x + 1

This factors into (x-1)(x-1) meaning x=1

For all the other equations they are equal because x=1.

1 to the power of anything is still one so each of the equations below will result in: 1+1/1 which is 2.

Therefore all of them are equal.

Answer:

One tip I can give is to always line up your decimals when adding or subtracting.

Step-by-step explanation:

If you don't then you will get it wrong.

Answer: b. counterexample

A counterexample contradicts the statement or definition you're trying to set up.

For example, if you said that 2x+3x = 7x was true for all x values, then all you need to do is try something like x = 2 to find the original equation simplifies to 10 = 14, which is false. In this case, the counterexample is x = 2 invalidating the equation 2x+3x = 7x.

[tex]2.4\times\:10\\[/tex]

Multiply without the decimal points then put the decimal point in the answer

[tex]24\times\:10=240\\[/tex]

2.4 has 1 decimal place

10 has 0 decimal places

Therefore, the answer has 1 decimal place

[tex]\\=24.0\\\\=24[/tex]

The value product of 2.4 × 10 will be 24.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

⇒ 2.4 × 10

Now,

Since, The expression is,

⇒ 2.4 × 10

After multiply, we get;

⇒ 2.4 × 10 = 24

Thus, The value = 24

Answer: A) reflection over the x-axis, plus a vertical translation

Step-by-step explanation:

Ok, when we have a function y = f(x)

> A reflection over the x-axis changes a point (x, y) to a point (x, -y), then for a function (x , y = f(x)) the point will change to (x, -y =- f(x))

then for a funtion g(x), this tranformation can be written as h(x) = -g(x).

> A vertical translation of A units (A positive) up for a function g(x) can be written as: h(x) = g(x) + A.

Then in this case we have:

y = g(x) = ln(x)

and the transformed function is h(x) = -ln(x) + 64

Then we can start with h(x) = g(x)

first do a reflection over the x-axis, and now we have:

h(x) = -g(x) = -ln(x)

And now we can do a vertical translation of 64 units up

h(x) = -g(x) + 64 = -ln(x) + 64

Then the correct option is:

A) reflection over the x-axis, plus a vertical translation
