Convert the following Logarithmic Equation into a Exponential Equation.
log_3(-2x+1)=-2y+6
Answer:
The conversion is given by [tex]3^{-2y+6} = -2x+1[/tex].
Step-by-step explanation:
Logarithmic Equation to Exponential Equation:
To realize the conversion of a logarithmic equation to an exponential equation, we need to understand the meaning of a logarithim. We have that:
[tex]\log_{a} b = c[/tex]
Means that:
[tex]b = a^c[/tex]
We are given the following equation:
[tex]\log_{3} (-2x+1) = -2y + 6[/tex]
It means that
[tex]3^{-2y+6} = -2x+1[/tex]
Which is the conversion.

If Noah ran 2 1/2 miles in 3/5 How fast, in miles per hour, did he run?
Can someone please help me with this problem I’m really struggling
Answer:
1
Step-by-step explanation:
I am assuming the question is asking which x value plugged into the function will give you a zero so
(-1)3 -8(-1)2 -23(-1)+30
so that simplyfiys to -1-8(1)+23+30
so that is -1-8+53
so -9+53
= 44
trying 3 we get
(3)3-8(3)2-23(3)+30
so that is 27 -72-69+30
and that is not zero
trying -10
we get
(-10)3-8(-10)2-23(-10)+30
which is -1000- 800+230+30
that is not zero so lastly trying 1 we get
(1)3-8(1)2-23(1)+30
which is 1-8-23+30
which is -7+7 which is zero

In the figure below, ab is congruent to bc, and ae intersects bf at c. what is the measurement of
Answer:
D. 104 degrees
Step-by-step explanation:
What the information at the top tells us is that triange ABC is an isosceles triangle. In an isosceles triangle the two base angles are congruent, this means that <A=<C. Additionally, because of vertical angles we know that <C is equal to 38. So to find m<B use the expression 180-(2*38). This simplifies to 180-76, which is 104.

Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.
x + y = 166
14x + 22y = 9
x + y = 166, , 14x + 22y = 9,
x + y = 9
22x + 14y = 166
x + y = 9, , 22x + 14y = 166,
x + y = 9
14x + 22y = 166
x + y = 9, , 14x + 22y = 166,
x + y = 36
166x + 9y=14x + 22y
The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Barbie spent $166 on clothes.
The cost of each pant = $22
The cost of each shirt = $14
Total number of items = 9
Now,
Let number of shirts = x
And, The number of pants = y
Since, Total number of items = 9
So, we can formulate;
⇒ x + y = 9
And, The cost of each pant = $22
The cost of each shirt = $14
So, We can formulate;
⇒ $14x + $22y = $166
Therefore, The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166

Clara and her family are vacationing in the Netherlands. They began a tour of the North Sea coastline at an elevation of
–
8 feet. By the end of the tour, their elevation had decreased by 5 feet. What was their elevation at the end of the tour?
Answer:
-13 feet
Step-by-step explanation:
The elevation of Clara and her Family at the end of the tour is the difference between their starting elevation of the change in elevation. Hence, their final elevation is - 13 feets
Given the Parameters :
Initial elevation = - 8 feets Decrease in elevation = 5 feetsFinal elevation can be obtained thus :
Initial elevation - Change in elevation
Final elevation = -8 feets - (5 feets)
Final elevation = - 8 - 5 = - 13 feets
Therefore, their final elevation at the end of the tour is - 13 feets

the regular price of the digital camera was aed 250. tyrone bought the digital camera at a discount of 40% how much did tyrone pay for the digital camera?
Answer:
Tyrone paid aed 150 for the digital camera.
Step-by-step explanation:
The regular price of the came was of aed 250.
Turone bought the camera at a discount of 40%.
So he paid 100% - 40% = 60% of the original price. So
0.6*250 = 150
Tyrone paid aed 150 for the digital camera.

Selena is flying a kite as shown below. Use the measurements to find how long the kite string is.
16 feet
12 feet
feet
Answer:
20 feet
Step-by-step explanation:
In this case, you'd use pythagoras's theorem (a^2 + b^2 = c^2)
The hypotenuse is always = c, so you'd set up the equation like this:
16^2 + 12^2 = c^2, where you're solving for c (to find out the length of the kite string)
This equation simplifies to 256 + 144 = c^2
which further simplifies to 400 = c^2
to solve for c, we square root both sides so the c is isolated:
[tex]\sqrt{400} = \sqrt{c}[/tex]
20 = c
so the length of the kite string is 20 feet
The required length of the kite string will be 20 feet.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
As per the question, we have to use Pythagoras's theorem
a² + b² = c²
Here hypotenuse = c,
Substitute the known values and we get
16² + 12² = c²,
Here c is the length of the kite string and simplifies the equation as:
256 + 144 = c²
c² = 400
c = √400
c = 20
Thus, the length of the kite string is 20 feet.

How does the function represented in the table change over equal intervals? What
does this tell you about the type of function it is?
For equal intervals changing in the independent variable, the corresponding dependent value does not change by equal differences, so it is not linear. which is the correct answer would be option (B).
What is the Linear function?A linear function is defined as an equation in which the highest exponent of the variable is always one.
The table is given in the question.
As per the given table,
The rate of change will be
During the first interval : (20-10)/(9-7) = 10/2
During the second interval : (30-20)/(11-9) = 10/2
During the third interval : (40-30)/(14-11) = 10/3
The corresponding dependent value does not vary by equal differences when equal intervals in the independent variable change, therefore it is not linear.
Hence, the correct answer would be an option (B).

x-2=-3x+2 pls show how to fully solve it
Answer:
x = 1
Step-by-step explanation:
One thing that is necessary to learn this is that whatever you do to one side, you must do to the other. If you substract 2, you must substract 2 from both sides.
Here are all the steps:
x - 2 = -3x + 2
x = -3x + 4 (by adding 2 to both sides)
4x = 4 (by adding 3x to both sides)
x = 1 (by dividing both sides by 4)
