Answer:
We will see that the domain of the function is:
D: {x | x ∈ R | x > -6}
How to find the domain of a function?
To find the domain of a function, we start by assuming that it is the set of all real numbers, and then we remove the problematic points.
In this case, we have a logarithm, and as you may remember, we can only evaluate the logarithm in positive values, so we need to remove all the values of x such that:
x + 6 ≤ 0
Solving for x, we get:
x ≤ -6
So the only values of x allowed are the ones that make the next inequality true:
x > -6.
Thus we can write the domain as:
D {x | x ∈ R | x > -6}
Where the second part, x ∈ R, is usually ignored, as we assume that x is a real number unless we specify that it is not, but just for completion, I wrote it.

Solve the system of equations
{3x−y=6
{6x+y=21
Answer:
The easiest way to solve this is by elimination.
3x - y = 6
6x + y = 21
Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:
9x = 27
Then solving for x leaves you with x = 3
Then you take the x value of three and plug it into to either of the equations, so
3(3) - y = 6
9 - y = 6
subtracting 9
-y = -3
then dividing by -1
y = 3
so the solution is x = 3 y = 3 or (3,3)
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
Add 3x + 6x, and execute the y, then -6 from 21 and you got ur answer of 15!

Solve the system of linear equations by elimination. Write your answer in the form (x,y)
-7x-8y=9
-4x+9y=-22
Answer:
Solution: (1,-2)
Step-by-step explanation:
System of Equations
Given the equations:
[tex]-7x-8y=9\qquad\qquad [1][/tex]
[tex]-4x+9y=-22\qquad\qquad [2][/tex]
We'll solve it by elimination. It means eliminating one of the variables by equating their coefficients. We select the variable y. To eliminate it, multiply the equation [1] by 9 and the equation[2] by 8:
-63x-72y=81
-32x+72y=-176
Adding up both equations:
-95x=-95
Solving:
x=-95/(-95)=1
x=1
Now to eliminate x and find y, multiply [1] by 4 and [2] by -7:
-28x-32y=36
28x-63y=154
Adding up both equations:
-95y=190
Solving:
y=190 / (-95) = -2
y=-2
Solution: (1,-2)
The radius of the circle shown below is 3 inches.
What is the area of this circle, in square inches?
Answer:Multiply Pi (3.1416) with the square of the radius (r) 2. The radius can be any measurement of length. This calculates the area as square units of the length used in the radius. Calculated out this gives an area of 28.2744 Square Inches.

Kellie is dlowed to watch up
to 90 minutes of TV per day.
If she watched 10 minutes
before school, how many 20-
minute TV episodes can she
watch after school?
90 min per day
10 min before school
=> she can watch TV during (90-10) 80 minutes after school
if each episode = 20 minutes
she will be able to watch 80:20 soit 4 episodes after school

Answer:
Step-by-step explanation:
c. y = (x^2 + 3)(x + 4)
y = x^3 + 4x^2 + 3x + 12
d. y = (x^2 + x) / √x
y = (x^2 + x) / x^1/2
y = x^2/ x^1/2 + x / x^1/2
y = x^(2 - 1/2) + x(1 - 1/2)
y = x^3/2 + x^1/2
or x = √(x^3) + √x
e. y = 5 /x^2
y = 5x^(-2)

1 over 7 times 7 times 7 times 7 times 7 times 7
negative 1 over 7 times 7 times 7 times 7 times 7 times 7
7
Answer:
The Answer is 1 over 7 times 7 times 7 times 7 times 7 times 7
Step-by-step explanation:
All you have to do is multiply the exponents.
[tex]7^{3*(-2)} =7^{-6}[/tex]
and the rule says :
[tex]x^{-a} = \frac{1}{x^{a} }[/tex]
So that means :
[tex]7^{-6} =\frac{1}{7^{6} } =\frac{1}{7*7*7*7*7*7}[/tex]

1 over 7 times 7 times 7 times 7 times 7 times 7 is equivalent to (73)−2.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here we have,
(7^3)(−2)
=7^(-6)
=1/7^6
=1/7*7*7*7*7*7
Hence, 1 over 7 times 7 times 7 times 7 times 7 times 7 is equivalent to (73)−2.

You find a pair of jeans on a clearance rack that originally cost $64. They were marked down 50%. The clearance price sign says an additional 50% off. Johnny says that you do not need to pay anything for the jeans. Do you agree? Why or Why not? Make sure that your answer is given with at least four sentences.
Answer and explanation:
Original cost of jeans =$64
Markdown by 50%= 0.50*64= $32
Additional discount by clearance sign 50% =0.50*32= $16
Therefore I disagree with Johnny. First the original price $64 was reduced by half of the price 50% of $64 =$32. Secondly the new price $32 is then also reduced by half of it 50% giving us $16. Therefore the discounts did not wipe off all the price as suggested by Johnny.

Originally a rectangle was twice as long as it was wide. When 4 m were added to its length and and 3 m subtracted
from its width, the resulting rectangle has an area of 600 m². Find the dimensions of the new rectangle.
Answer:
Step-by-step explanation:
Original rectangle
L = 2*w
w = w
New rectangle
2w + 4
w - 3
Area New rectangle
(2w + 4)(w - 3) = 600 Remove the brackets
2w^2 - 6w + 4w - 12 = 600 Combine the left
2w^2 - 2w - 12 = 600 Subtract 600 from both sides
2w^2 - 2w - 600 - 12 = 0 Combine
2w^2 - 2w - 612 = 0 This factors.
(w- 18)(w + 17) = 0
w + 17 will produce nothing useful. What is - 17 m ? Can you measure it?
w = 18
check
Original Triangle
w = 18
L = 36
Derived Triangle
L = 36 + 4 = 40
w = 18 - 3 = 15
LW = 600
Answer
L = 40W = 15pls help me thx very desparate

-2k+13=-8k-35
What’s k
Answer:
k = -8
Step-by-step explanation:
-2k+13=-8k-35
Add 8k to each side
-2k+8k+13=-8k+8k-35
6k +13 = -35
Subtract 13 from each side
6k+13-13 = -35-13
6k = -48
Divide by 6
6k/6 = -48/6
k = -8

Bag contains 11 counters. 5 are white
a counter is taken out and not replaced. Second one is taken out. Prob that one of them is white
Answer:
6/11
Step-by-step explanation:
After taking 2 counters with no replacement, that only one of these is white. We will see that the probability is 6/11.
Given that;
there are 11 counters, 5 of them are white, 6 are not white
First we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:
p = 5/11
And, also notice that there are 2 permutations:
first white, then non-white.
first non-white, then white.
So we need to add a factor 2.
P = 2*p*q = 2*(5/11)*(6/10) = 6/11
The probability is 6/11
We can also Do:
11/11 = Whole
11 - 5 = 6
Hence, Answer = 6/11
