Explain the error in Julie’s work in rewriting the radical expression.
Answer:
The negative numbers do not have square roots. Therefore the question does not have a solution. That is where Julie made a mistake.
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
First, let's take a look at this property:
[tex] \displaystyle \large{ \sqrt{a} \sqrt{b} = \sqrt{ab} }[/tex]
This only works for a and b ≥ 0.
As for a & b < 0 which results in Imaginary Number, we have to convert in 'i' form.
We know that:-
[tex] \displaystyle \large{ i = \sqrt{ - 1} }[/tex]
Thus:
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{3} i \cdot \sqrt{12}i }[/tex]
Then we can multiply 12 & 3 in square root.
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36} {i}^{2} }[/tex]
We know that:
[tex] \displaystyle \large{ {i}^{2} = - 1}[/tex]
Convert i^2 to -1
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = \sqrt{36}( - 1) } \\ \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - \sqrt{36}}[/tex]
Then evaluate √36 which is 6.
[tex] \displaystyle \large{ \sqrt{ - 3} \cdot \sqrt{ - 12} = - 6}[/tex]
Therefore the answer should be -6.
Conclusion
Julie cannot use the √a√b = √ab property first because a & b both are < 0 and the property applies for a ≥ 0, b ≥ 0.

Give the coordinates of D (-2, -4) after a 270 degrees counterclockwise rotation about the origin followed by a reflection across the x-axis
Transformation involves changing the position of a point.
The image of D after the transformation is (-4,-2)
The point is given as:
[tex]\mathbf{D = (-2,-4)}[/tex]
The rule of 270 degrees counterclockwise rotation is:
[tex]\mathbf{(x,y) \to (y,-x)}[/tex]
So, we have:
[tex]\mathbf{D' = (-4,2)}[/tex]
The rule of reflection across the x-axis is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{D" = (-4,-2)}[/tex]
Hence, the image of D after the transformation is (-4,-2)

You have a total of 12 cards in four different colors. The probability of drawing a green card is the same as the probability of drawing a yellow card. The probability of drawing a red card is 1-4 and of drawing a blue card is 1-12. How many green cards are in the box
Answer:
4
Step-by-step explanation:
Let's start with the easiest bits.
We know the probability of drawing a red card is 1/4, this means every four cards there is one red. So, 12/4 = 3, there are 3 red cards in the 12 card pile.
Next, we are also given the probability of drawing a blue card us 1/12. In the same fashion, we can figure out there is 1 blue card.
Finally, we are told the probability of drawing a green card is the same as drawing a yellow card. Therefore there is the same amount of green cards as yellow.
There are 8 cards left that are green or yellow, as 12 - 1 - 3 is 8. 8/2 is 4, so there are 4 green cards in the box.

Marco owed his father $150 and began paying him back $20 at the end of
each week, beginning November 1. Joni owed her father $130 and began
paying him back $15 at the end of each week, beginning on the same
day. What Marco owed his father in dollars at the end of n weeks can be
represented by f(n) = 150 - 20n. What Joni owed her father in dollars at the
-
end of n weeks can be represented by g(n) = 130 - 15n.
Find the value of n for which f(n) = g(n). What does that value mean in this
situation?
Answer:
The important clue here is when they say both The girls owe the same amount so what they mean is equate both the functions
so we get
150 - 20n = 130 - 15n
Now n gives us the number of weeks so solve for n
20n - 15n = 150 - 130
5n = 20
n = 4
Now check your solution
150-20(4) = 70
130 - 15(4) = 70
So our answer checks out after 4 weeks both girls who their dads the same amount of money .

(Change in price / old price) * 100%
((New price - old price) / old price) * 100%

Suppose a line graphed on a coordinate plane represents the distance traveled in miles by an automobile as a function of time in hours. Assuming that the Nationship between time and distance traveled is proportional, which of these statements is correct? Select one that applies
A. If the automobile was going 25 mph, the slope of the line is -1/25
B.If the automobile was going 30 mph, the slope of the line is 1/30
C.If the automobile was going 35 mph, the y-intercept of the line is 35.
D. If the automobile was going 40 mph, the y-intercept of the line is -1/40
E.If the automobile was going 45 mph, the y-intercept of the line is 1/45
F.If the automobile was going 50 mph, the slope of the line is 50.
The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.
Since distance traveled in miles is graphed as a function of time in hours, this implies that distance is on the y-axis and time in hours is on the x-axis.
So, the slope of the graph is distance/time and its unit is miles/hour = miles per hour = mph.
This slope represents the speed of the automobile.
So an automobile going at 50 mph represent the slope of the line which is 50.
The answer to the question which of these statements is correct is F. If the automobile was going 50 mph, the slope of the line is 50.

8: Harry is 3 years older and Andy is twice as old as
Sam. The total of their ages is 27. If Sam is x years old
form an equation using this information.
Step-by-step explanation:
given,
Harry = 3yrs
Andy = 2x ( twice as old as sam )
sam = x
their sum = 27
a/q
→ 2x + x + 3 = 27
→ 3x = 27 - 3 = 24
→ x = 24/3 = 8
→ x = 8
therefore, age of sam is 8 and Andy is 16 and Harry is 3.
the equation is
2x + x + 3 = 27
hope this answer helps you..and may u have a great day ahead!
The equation formed using the information given is x + (x + 3) + 2x = 27. Sam is 6 years old. Let x be Sam's age.
According to the given information:
1. Harry is 3 years older than Sam, so Harry's age is (x + 3) years.
2. Andy is twice as old as Sam, so Andy's age is 2x years.
3. The total of their ages is 27, so we can add their ages together and set it equal to 27:
x + (x + 3) + 2x = 27
Now, let's simplify the equation:
Combine like terms:
x + x + 3 + 2x = 27
Combine the x terms:
4x + 3 = 27
Now, we want to isolate the variable x on one side, so let's move the constant term (3) to the other side of the equation by subtracting 3 from both sides:
4x = 27 - 3
4x = 24
Finally, solve for x by dividing both sides by 4:
x = 24 / 4
x = 6
So, Sam is 6 years old.

Solve for a. 50 - a/11 = 58
Answer:
a = -88
Step-by-step explanation:
50− a/ 11 =58
50 + -1/11 x a = 58
-1/11 x a + 50 = 58
Subtract 50 from both sides
-1/11 x a - 50 (-50) = 58 (-50)
Now multiply both sides by 11/-1
(11/-1) x (-1/11 x a) = (11/-1) x 8
a = -88

Answer:

Answer:
C: No solutions.
Step-by-step explanation:
When solving an equation and it provides a false statement, it implies that there are no values that could satisfy the given equation. Simply put, the word "equation" in itself must provide equal values on either sides of the equal sign.
“No solution” means that there is no value, not even 0, which would satisfy the equation.
Therefore, the correct answer is C: No solutions.
