Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(x9) = x4 • SQRT(x)
Simplified Root :
x4 • sqrt(x)
5) Ana traveled from San Antonio to Eagle Pass. She went by car with a
speed of 75 miles per hour and it took her 3 hours to reach her
destination. What is the distance Ana traveled? *
She traveled 225 miles
She traveled 75 miles
She traveled 25 miles
She traveled 78 miles
Answer:
225 miles because you multiple 75 times 3 since she traveled for 3 hours and in each one she did 75 miles.multiplying will get 225 miles
Step-by-step explanation:
75 × 3 = 225

Slope= -4
Point = (2,-4)
Answer:
y=-4x+4
Step-by-step explanation:
equation of a line: y=mx+b (m:slope, b: y-intercept)
m=-4 (given)
y=-4x+b
substitute with (2, -4): -4=(-4)(2)+b
solve for b: -4=-8+b, b=4

A realtor sells 3 houses this month for a total of $825,000, and each buyer uses her company to process their loan. She earns a base pay of $2,600 each month plus 1.5% of her total house sales. She also gets a fee of $12 for each loan she gets serviced through her company. What are her total earnings for the month?
Answer:
15,011
Step-by-step explanation:
Because 1.5 percent of 825,000 is 12375. She gets 2,600, so add that, and 12 times 3 for 3 houses is 36.
Add 12,375+2,600+36, you get 15,011!
The total monthly earnings of the seller would be $15,011.
Given that,
A realtor sells 3 houses this month for a total of $825,000, and each buyer uses her company to process their loan. She earns a base pay of $2,600 each month plus 1.5% of her total house sales. She also gets a fee of $12 for each loan she gets serviced through her company. To determine the total earnings for the month.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Total earning = 2600 + 1.5% of 825000 + 12
Total earning = 2600 + 12375 +12
Total earning = $15,011
Thus, the total monthly earnings of the seller would be $15,011.

Here is the complete question
Write a verbal expression for each algebraic expression.
1. 9a²
2. 5²
3. c + 2d
4. 4 - 5h
5. 2b²
6. 7x³ - 1
7. p⁴ + 6r
8. 3n² - x
Solution
1. The term a is squared then multiplied by 9. So, we have "a squared multiplied by nine."
2. Since we have figure 5, and it is raised to the power 2, we have "Five squared."
3. We have the first term as letter c and the second term as 2 times letter d, we have "c plus 2 times d"
4. We have the first term as figure 4 and subtract 5 times h which is the second term from it, we have "Four minus 5 times h".
5. We have the letter b raised to the power of 2 as b squared. It is then multiplied by 2. So, we have, "Two times b squared."
6. We have the first term as letter x raised to the power of 3 which is "x cubed". This is then multiplied by 7. We then subtract 1 from it as the second term to give the expression, "Seven times x cubed minus 1"
7. The first term is p raised to the fourth power and the second term is 6 times letter r. So, the expression is "p raised to the fourth power plus 6 times r".
8. The first term is n squared multiplied by 3. We then subtract the second term x from it. The expression is thus, "Three times n squared minus x".

We pick points and see if they are true for the inequality
(0,0)
See if it is true
0-3(0) ≤ 6
0+0 ≤ 6
0 ≤ 6
True
Picking another point
(6,-1)
6-3(-1) ≤ 6
6+3 ≤ 6

Write the equation of the line that passes through (-3, -20) and (1, 4).
Answer:
y=6x-2
Step-by-step explanation:
first step: find the slope
equation to find slope: (y2-y1)/(x2-x1)
let x1, y1 be (-3, -20)
let x2, y2 be (1, 4)
(4 - (-20))/(1 - (-3)) = 24/4 = 6
plug in 6 and x,y to find b
4=(6)(1) + b
subtract 6 on both sides = -2=b
y=6x-2
Find the distance between the two points rounding to the nearest tenth (if

Four swimmers competed in the 100-meter freestyle.
Their times were 68.92 seconds, 72.3 seconds, 73.2
seconds, and 69.15 seconds.
If the lowest number represents the person who came
in first, what was the time of the person who came in
third place?
O 68.92 seconds
O 72.3 seconds
O 73.2 seconds
O 69.15 seconds
Answer: 72.3
Step-by-step explanation: least to greatest would be 68.92, 69.15, 72.3, 73.2
So with that information and knowing that the lowest number represents the person who came in first, then we know 72.3 is the person who came in third place.

joe measured a brick using a ruler with centimeters and got 9 cm. he then measured the same brick using a ruler with millimeters and got 90 mm. are these measurements equivalent?
Answer:
yes
Step-by-step explanation:
1 cm=10mm. if 1cm=10mm what about 9cm
Yes, they are equivalent when he got 9 cm and we got 90 mm while measuring it.
Calculation of the measurement:Since he used the ruler with centimeters and got 9 cm
And, if he used a ruler with millimeters and got 90 mm
So the measurement should be equal
As we know that 1 cm=10mm
So based on this, they are equivalent

Christian just lit a new candle and then let it burn all the way down to nothing. The length of the candle remaining unburned, in inches, can be modeled by the equation L=6−t where t represents the number of hours since the candle was lit. What is the slope of the equation and what is its interpretation in the context of the problem?
Given:
The length of the candle remaining unburned, in inches, can be modeled by the equation
[tex]L=6-t[/tex]
where, t represents the number of hours since the candle was lit.
To find:
The slope and its interpretation in the context of the problem.
Solution:
Slope intercept form of a linear function is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
We have,
[tex]L=6-t[/tex]
It can be written as
[tex]L=6+(-1)t[/tex]
The coefficient of t is -1. So, using slope intercept form the slope of this equation is -1.
Here, -1 means length of the candle remaining unburned is decreasing at the rate of 1 inch per hour.
