write the expression for when you translate the graph of y= |x+7| one unit to the left
HELP PLSSSS
Answer:
y = |x+8|
Step-by-step explanation:
Translating an absolute value graph one unit to the left means adding 1 inside the absolute value brackets.
Translating an absolute value graph one unit to the right means adding (-1) inside of the absolute value brackets.
Translating an absolute value graph one unit up means adding 1 outside the absolute value brackets.
Translating an absolute value graph one unit down means adding (-1) outside the absolute value brackets.

Rationalize the denominator of the expression 2 - √ 3 / √ 6
Step-by-step explanation:
[tex] \to \dfrac{2 - \sqrt{3} }{ \sqrt{6} } [/tex]
Conjugate of √a is √a. So, conjugate of √6 is √6. Multiplying √6 with both numerator and denominator.[tex] \to \dfrac{2 - \sqrt{3} }{ \sqrt{6} } \times \dfrac{ \sqrt{6} }{ \sqrt{6} } [/tex]
[tex] \to \dfrac{ \sqrt{6}( 2 - \sqrt{3} )}{ {(\sqrt{6})}^{2} } [/tex]
[tex] \to \dfrac{ 2 \sqrt{6} - \sqrt{18} }{ 6 } [/tex]
[tex] \to \dfrac{ 2 \sqrt{6} - 3 \sqrt{2} }{ 6 } [/tex]
[tex] \to \dfrac{ \sqrt{6}}{3} - \dfrac{ \sqrt{2} }{ 2 } [/tex]

of the hypotenuse?
4 cm
5 cm
Answer:
6.4 cm
Step-by-step explanation:
i think you'd use pythagoras theorem if you don't know any of the angles . a^2 + b^2 = c^2 . so 4^2 + 5^2 = square root 41 ,, = 6.403124237 cm
i apologise if it is incorrect ^^

Choose a method you prefer to solve for a system of linear equations.
2x + 4y = -4
2x-y=6
Answer:
Elimination
x = 2
y = -2
Step-by-step explanation:
Elimination
2x + 4y = -4
2x - y = 6
Subtract the second equation from the first
5y = -10
Divide both sides by 5
y = -2
---------------------
Substitute for y = -2 in the second equation
2x - -2 = 6
2x + 2 = 6
subtract 2 from both sides
2x = 4
Divide both sides by 2
x = 2

If 2x + 5 = 82, then 12x = ?
A 5
B
10
C 15
D 20
Answer:
2x= 38.5
Step-by-step explanation:
I'm not sure where u got 12x but 2 x = 38.5:
2x + 5 =82
subtract 5 for 82
2x = 77
77 divided by 2 is 38.5
x = 38.5

PLEASE HELP!!! The question is in an image....
9514 1404 393
Answer:
-√3
Step-by-step explanation:
We note that this matches the form for the tangent of the difference of two angles:
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(βb))
Here, we have α = 25π/24 and β = 3π/8. Then the angle difference is ...
α -β = π(25/24 -3/8) = π(2/3)
The value you seek is ...
tan(2π/3) = -√3
Answer choices are

Answer: 990 ways
Step-by-step explanation:
For the first chicken, there are 11 slots it could be, or 11. For the next chicken, there are 10 available, or 10. Same thing for the third chicken, with 9. Thus, simply do 11*10*9 to get 990.
in a class of 24 students, how many different 3 person teams for a group project can the teacher make?
Answer:
The teacher can make 8 different 3 person teams
Step-by-step explanation:
Since there is a total of 24 students and the teacher wants to make as many 3 person groups as he/she can you would just do 24 divided by 3 which would equal 8 different teams of 3 people. So the teacher can make 8 different groups of 3 people
What is the slope of the line that passes through the points (2, 3) and (8, 6)
Answer:
The slope of the line that passes through the points (2, 3) and (8, 6) is [tex]\frac{1}{2}[/tex].
Step-by-step explanation:
To find the slope of two points, divide the difference between the y values by the difference between x values, you can remember this by the mnenomic "rise over run". In this case, the difference between y and x values would be 6 - 3 = 3 and 8 - 2 = 6 respectively. This means the slope between the two points (2, 3) and (8, 6) is [tex]\frac{3}{6}[/tex] or [tex]\frac{1}{2}[/tex].

latoya made $80 for 5 hours of work. At the same rate, how much would she make for 13 hours of work
Answer:
$208
Step-by-step explanation:
First, divide.
80 ÷ 5 = 16
Next, multiply.
16 × 13 = 208
Lastly, have a wonderful day! :)
Answer:
At the same rate, Latoya would make $208 for 13 hours of work.
Step-by-step explanation:
Since Latoya made $80 for 5 hours of work, that means she made a unit rate of $16 per hour. By working at the same rate for 13 hours, she would make a total of [tex]16 * 13 =[/tex] $208.

The expression above can also be written in the form vb.
For this expression, a =
b=
and cu
Answer:
a = 3, b = 6, c = 5
Answers:
a = 3, b = 6, c = 5
==============================================
Explanation:
There's not much to say other that the rule we use is
[tex]\sqrt[c]{a^b} = a^{b/c}[/tex]
The c is the index of the root or radical. It's the denominator of the fractional exponent b/c. Comparing terms, we see that a = 3, b = 6 and c = 5.
You could simplify the a^b portion, but it seems like your teacher doesn't want that (right now).
-----------
Side notes:
if c = 2, then we have a square root and often the index number isn't shown at all. So [tex]\sqrt[2]{x} = \sqrt{x}[/tex]. Its only when c > 2 is when we can't drop the number, or else it'll get mistaken for a square root. If c = 1, then we won't have any radical. We'll have a^(b/c) = a^b if c = 1.A population of bacteria doubles every 18 hours. Initially, the population of bacteria is 50.

A system has three possible states, 0, 1 and 2. Every hour it makes a transition to a different state, which is determined by a coin flip. For example, from state 0, it makes a transition to state 1 or state 2 with probabilities 0.5 and 0.5.
a. Find the transition probability matrix.
b. Find the three-step transition probability matrix.
c. Find the steady-state distribution of the Markov chain.
Answer:
Step-by-step explanation:
From the given information;
the transition probability matrix (TPM) for state 0, 1, 2 is:
[tex]P =\left[\begin{array}{ccc}0&0.5&0.5\\0.5&0&0.5\\0.5&0.5&0\end{array}\right][/tex]
The three-step TPM is done by a simple matrix multiplication which is computed as follows:
[tex]P^3 = \left[\begin{array}{ccc}0.250&0.3757 &0.375\\0.375&0.250&0.375\\0.375&0.375&0.250\end{array}\right][/tex]
The steady-state distribution of the Markov Chain is determined by first solving the system πp = π together with the normalizing condition
here;
π₁ + π₂ + π₃ = 1
So;
0.5π₂ + 0.5π₃ = π₁
⇒ π₂ + π₃ = 2π₁
0.5π₁ + 0.5π₃ = π₂
⇒ π₁ + π₃ = 2π₂
0.5π₁ + 0.5π₂ = π₃
⇒ π₁ + π₂ = 2π₃
Thus, π₁ + π₂ + π₃ = 1
This can be re-written as:
1 - π₁ = 2π₁
1 - π₂ = 2π₂
1 - π₃ = 2π₃
∴
1 = 3π₁
π₁ = 1/3
1 = 3π₂
π₂ = 1/3
1 = 3π₃
π₃ = 1/3
Hence, the steady-state probability distribution is π = [1/3, 1/3, 1/3]

Write the ratios for sin A and cos A.
Answer:
The correct answer is A. Sin A= 3/5 cos A = 4/5
Let me see.
sin A =opposite/hypotenuse
cos A = adjacent/hypotenuse
Look at the diagram.
Clearly, opposite angle A we have 3.
The hypotenuse is 5.
So, we conclude that sin A = 3/5.
Go back to the diagram.
The height of the triangle is the adjacent side to angle A for this problem.
Think about it this way:
The adjacent side is the height 4.
The hypotenuse we know as 5.
So, cos A = 4/5.
The answer is choice A

The independent variable of a data set is w, while the dependent variable is X.
Which of these is a response variable?
A. Both W and X
B. X
C. W
D. Neither W nor X
Please help rn
Answer:
It's B because a response variable is the same as a dependent variable. A dependent variable is basically the "effect" in the "cause-and-effect" scenario. The dependent variable DEPENDS on the independent variable.
