Answer:

C. Are all real numbers greater than or equal to -8.

Step-by-step explanation:

Real numbers can be said to be all continuous values of quantity, which can be negative or positive values.

The range of h, h(x), in the table given are all real numbers.

The least of the range of h on the table is -8. All the other range values, namely, -7, 1, 17, and 41 are all greater than -8. None is less than -8.

Therefore, we can conclude that the range values of h "are all real numbers greater than or equal to -8".

Answer:

Step-by-step explanation:

x + 300 =369

x = 69

subtract 300 on both sides

Hey there!

[tex]Answer:\boxed{x=69}[/tex]

[tex]Explanation:[/tex]

[tex]x+300=369[/tex]

To solve, you can do 369 - 300.

[tex]369-300=69[/tex]

Let's make x to 69 to see it it's true.

[tex]69+300=369[/tex]

x = 69 is true.

[tex]\boxed{x=69}\text{ is your answer.}[/tex]

Answer:

$1323.00

Step-by-step explanation:

A simple equation that can be used to figure this out is:

p*1.5*o=t

The variables mean:

p- hourly pay

o- hours worked overtime

t- total amount of money earned.

(Also, the 1.5 is always used to calculate overtime, no matter what job, unless otherwise specified, and as referred in the problem as "time and a half").

So, to finally work out this problem:

($14*1.5)*63=?

first, (14*1.5)= $21

($21*63)= $1323.

Answer:

Step-by-step explanation:

The circumference of a circle's formula is pi*d (d being diameter).

If it only shows you the radius, then the formula would be 2*pi*r (r being radius), this is the same as pi*d.

2*r = d

The approximate side length is between 10 ft and 11 ft

Step-by-step explanation:

Here, we are interested in calculating the approximate length of the square shaped pool.

Mathematically, the area of a square is s^2 where s represents the length of its side

in this case; s^2 = 120

s = √120

s = 10.95 approximately

So the length of the side of the square is between 10 and 11 ft

Step-by-step explanation:

Lines can be divided in smaller segments by using ratios

The coordinates of B are: [tex]\mathbf{ (\frac{4}{3},-\frac{10}{3})}[/tex]

The given parameters are:

[tex]\mathbf{A =(-2,5)}[/tex]

[tex]\mathbf{C =(2,-5)}[/tex]

[tex]\mathbf{m : n = 5 : 1}[/tex]

The coordinate of B is calculated using:

[tex]\mathbf{B = \frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n}}[/tex]

So, we have:

[tex]\mathbf{B = \frac{5 \times 2 + 1 \times -2}{5 +1},\frac{5 \times -5 + 1 \times 5}{5 + 1}}[/tex]

[tex]\mathbf{B = (\frac{8}{6},\frac{-20}{6})}[/tex]

Simplify fraction

[tex]\mathbf{B = (\frac{4}{3},-\frac{10}{3})}[/tex]

Hence, the coordinates of B are: [tex]\mathbf{ (\frac{4}{3},-\frac{10}{3})}[/tex]

The Domain : {(−∞,∞), {x/x∈R} and Range : {(−∞,∞), {y/y∈R} of the function  f(x)=2x-5

A relation is a function if it has only One y-value for each x-value.

We have to find the domain and range of f(x)=2x-5

The domain of the expression is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Hey there!

The equation in y=mx+b is [tex]y=-\frac{1}{2}x+1[/tex]

To write in standard form, it would look like: [tex]Ax+By=C[/tex]

As you can see, the x and y should be on the same side. You will need to move [tex]-\frac{1}{2}x[/tex] to the other side. When moving a number/variable to the other side, the sign changes, therefore, the negative sign will be removed. It is also the same as adding the opposite of it to both sides.

[tex]y=-\frac{1}{2}x+1\\ y+\frac{1}{2}x=-\frac{1}{2}x+\frac{1}{2}x + 1\\y+\frac{1}{2}x=1[/tex]

In standard form, there are no fractions, only whole numbers. The fraction can be removed by multiplying it by its opposite. The opposite of [tex]\frac{1}{2}[/tex] is [tex]\frac{2}{1} \rightarrow 2[/tex].

The entire equation has to be multiplied by 2:

[tex](y+\frac{1}{2}x=1) \times 2 \rightarrow 2y+x=2[/tex]

[tex]x+2y=2[/tex]

Answer:

a = 3

Step-by-step explanation:

Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)

x² + 3x - 18 = (x - 3)(x + 6)

Thus both expressions have a common factor of (x - 3) , thus

a = 3

The answer is

.3

Because

4/10 =.4 so David ate .4

3/10=.3 so jenn ate .3

add them to gether u get .7

subtract it by 1.0 because its a whole and you get .3

Answer:

2(n-4)

Step-by-step explanation:

The common factor of this expression is 2 because it can divide into both 2n and 4; therefore, if you divide the entire expression by 2, you'll result in an answer of 2(n-4).

The common factor out of each expression 2(n-4)

Since factorization is the technique of breaking a number into smaller numbers that multiplied together will give that original form.

We are given the expression;

2n - 4

The common factor of this expression is 2

Since it can divide into both 2n and 4;

Therefore, if we divide the entire expression by 2, results in an answer of 2(n-4).
