The domain of g is x ≥ -2, which is option B.
What is Translation?Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.
Given that,
the graph of g is a translation 2 units left of the graph of f(x) = x√x.
When f(x) is translated k units to the left, the new function will be f(x + k).
So the new function g is,
g(x) = (x + 2) √(x + 2)
In order for the function to be defined, the part inside the square root must be greater than or equal to 0.
x + 2 ≥ 0
x ≥ -2

An equation is shown below:
8(2x – 14) + 13 = 4x – 27
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)
Answers
Answer:
x = 6
Step-by-step explanation:
8(2x – 14) + 13 = 4x – 27
Lets go in the order of PEMDAS (Parantheses, Exponents, Multiplication, Division, Addition, Subtraction)
First, distribute 8.
8(2x – 14)
[tex]8*2x=16[/tex]
[tex]8*-14=-112[/tex]
So now our equation is:
16x – 112 + 13 = 4x – 27
Now we can add. We will add 13 to -112.
[tex]-112 +13=-99[/tex]
Now our equation looks like this:
16x – 99 = 4x – 27
Now we have to try to get the variable (x) on one side of the equation.
To do this, we will subtract 4x from both sides of the equation.
16x – 99 = 4x – 27
-4x -4x
12x - 99 = -27
Now we can add 99 to -27.
[tex]99 + (-27) = 72[/tex]
Now we have
12x = 72
Our last step is to divide both sides by 12:
[tex]\frac{12x}{12}= \frac{72}{12}[/tex]
We get x = 6.
Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a great day!

Answer:
Step-by-step explanation:
A.
8(2x – 14) + 13 = 4x – 27
Step 1: Distribute 8, meaning multiply 2x and -4 using 8
8(2x – 14)
8(2x) + 8(-14)
16x - 112
New equation:
16x - 112 + 13 = 4x – 27
Step 2: Add any numbers or like terms:
16x - 112 + 13 = 4x – 27
16x - 109 = 4x - 27
New equation:
16x - 99 = 4x - 27
Step 3: Isolate the variable on one side
16x - 99 = 4x - 27
-4x -4x
12x - 99 = - 27
+ 99 + 99
12x = 72
Step 4: Divide both sides by 12
12x = 72
/12 /12
x = 6
B.
Check your answer:
8(2x – 14) + 13 = 4x – 27
8(2(6) - 14) + 13 = 4(6) - 27
8(12 - 14) + 13 = 4(6) - 27
8(-2) + 13 = 24 - 27
-16 + 13 = 24 - 27
-3 = -3
This statement is correct
Therefore, our answer (x = 6) is correct.

Is (-7, -3) a solution to this system of equations?
x = -7
y = -x - 10
Yes or no
Answers
===========================================================
Explanation:
The point (-7,-3) means x = -7 and x = -3
Right off the bat, the first equation x = -7 is proven true based on the first coordinate.
Let's now plug the coordinates into the second equation.
y = -x-10
-3 = -(-7)-10
-3 = 7-10
-3 = -3
Which is a true statement.
Both equations are true when (x,y) = (-7,-3)
This is why it is a solution to the system. It turns out it's the only solution to this system. This system is consistent and independent.
You can use a graphing tool like Desmos to plot the two equations, and you should see them crossing at the point (-7,-3)
Answer:
The answer is yes
*View the attached graph to check your answer graphically.*
Step-by-step explanation:
x = -7
y = -x - 10
For this problem, I will be using substitution, since the second equation is already in the slope-intercept form.
First, I will substitute the first equation, for x, into the first equation:
x = -7
y = -x - 10
y = -(-7) - 10 <== multiplying two negatives, makes a positive
y = 7 - 10
y = - 3 <== the value of y
Now, we find the value of x by substituting - 3 for y:
y = -x - 10
- 3 = -x - 10
+10 +10
7 = -x <== you can't have a negative variable
/-1 /-1
-7 = x <== the value of x
(x, y) ==> (-7, -3)
Therefore, yes (-7,-3) is a solution to this system of equations.

What percent of the students received a score below 64, if the mean grade on a test was 70 and the standard deviation was 6.
Answers
Using the normal distribution, it is found that 15.87% of the students received a score below 64.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, the mean and the standard deviation are given by, respectively: [tex]\mu = 70, \sigma = 6[/tex].
The proportion of students who received a score below 64 is the p-value of Z when X = 64, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{64 - 70}{6}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a p-value of 0.1587.
Hence, 15.87% of the students received a score below 64.

The amount of the annual withdrawals will be $16,574.24.The amount is the sum of the principal and the simple interest gain.
What is the amount?The complete repayment of money at the end of the time period for which it was borrowed is referred to as the amount.
The given data in the problem is;
P ia the annual payment
PV is the present value = $150,261
r is the rate of intreast = 9.1% = 0.091
n is the time period= 20
The formula for the annual payment is found as;
[tex]\rm P= \frac{r \times PV}{1-(1+r)^{-n}} \\\\ \rm P= \frac{0.091 \times 150261}{1-(1+0.091)^{-20}} \\\\ \rm P=16,754.2437[/tex]

Step-by-step explanation:
You want the base of a triangle, given its height is 3 cm. From the base of 12 cm, the same triangle has a height of 2 cm.
AreaThe area of a triangle is given by the formula ...
A = 1/2bh
The area will be the same for any (base, height) pair of dimensions. The height is always measured perpendicular to the base. The base is generally one side of the triangle.
ApplicationHere, the longest side is labeled 12 cm, and the perpendicular distance to the opposite vertex (height) is labeled 2 cm. This means the triangle area is ...
A = (1/2)(12 cm)(2 cm) = 12 cm²
The distance perpendicular to the unknown side is shown as 3 cm. This gives you a clue that using the area of the triangle to find the unknown side is probably useful.
A = 1/2bh
12 cm² = 1/2(b)(3 cm)
8 cm = b . . . . . . . . . . . . multiply by 2/(3 cm)
The value that goes in the box is 8.

A money box contains only 10-cent and 20-cent coins. There are 40 coins with a total value of $6.50. How many coins of each?
Answers
Answer:
10x+20y= 350
Step-by-step explanation:
Add the decimal. 3.50
Let's assume that all the coins are 10-cent coins.
The total value would be 10 x 40 = 400 cents = $4
So, it would be $2.5 less than the actual total value,
We now know that not all the coins are 10-cent coins, so now we will replace 1 10-cent coins with a 20-cent coins.
Everytime we switch a 1 10-cent coins to a 20-cent coins, the value go up 10 cents. So, we need to switch 25 times (to make the value goes up $2.5)
-> There are 25 20-cent coins and 15 10-cent coins
Recheck : 25 x 20 + 15 x 10 = 500 + 15 = 650 cents = $6.5
