Answer:
y = [tex]\frac{x^{2} + 27}{8}[/tex]
Step-by-step explanation:
To find the inverse, we will set it equal to y, switch the x and y values, then solve for y.
[Given] h(x)=3 square root x -3
[Rewrite] y = 3 [tex]\sqrt{x-3}[/tex]
[Switch values] x = 3 [tex]\sqrt{y-3}[/tex]
[Square both sides] x² = 9(y - 3)
[Distrubte] x² = 8y - 27
[Add 27 to both sides & flip equation] 8y = x² + 27
[Divide both sides of 8] y = [tex]\frac{x^{2} + 27}{8}[/tex]

Am I right or wrong? If I'm wrong which is right?
Answer: The correct answer is (3x+1)(x-4)
Step-by-step explanation:
(3x+1)(x-4)
3x(x-4) + 1(x-4)
3x^2 - 12x + x-4
3x^2 - (12x + x)-4
3x^2 - 11 x - 4
Find the exact circumference.
Answer:
25π
Step-by-step explanation:
C= πd
d=√(24²+7²)=√(576+49)=√625=25
C=25π
Answer:
Step-by-step explanation:
First off, divide 24 by 2 as that would give you the radius of the circle
24cm / 2cm = 12cm
Next, use the formula to calculate the circumference of a circle and plug in radius:
C = 2 x π x r
= 2 x π x 12cm
= 75.40cm is the circumference

Olivia solved the equation a=2(5−3a) + 4.
Match the property with each of Olivia's steps for solving the equation.
Answer:
first one is distributive property
next one is combine like terms
then addition property of equality
then division property of equality
Step-by-step explanation: i got it right
The solution to the equation is a = 2
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
a = 2 ( 5 - 3a ) + 4
By distributive property , we get
a = 10 - 6a + 4
By combining the like terms , we get
a = 14 - 6a
By addition property of equality , we get
7a = 14
By division property of equality , we get
a = 2
Hence , the equation is solved and a = 2

An inch is exactly 2.54 centimeters. Write an equation to convert the number of inches x to the corresponding length in centimeters.
Answer:
What's 2.54 cm in inches?
To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. As an example, let's say you have a piece of wood measuring 50cm and you want to convert it into inches. To get your answer, divide your cm figure by 2.54. So, 50 ÷ 2.54 = 19.685 inches.
Step-by-step explanation:
Answer: 2.54x12 is 30.48
We can write:
2.54x
Where 'x' is the number of inches.
Plug in 12 for 'x':
2.54(12)
30.48
So 12 inches is approximately 30.48 centimeters.

I don't understand this question, can someone help please?
Devon wants to write an equation for a line that passes through 2 of the data points he has collected. The points are (8, 5) and (–12, –9). He writes the equation
7x – 10y = 3. Is this a good model? Explain your reasoning.
Answer:
No. Correct is 7x - 10y = 6.
Step-by-step explanation:
The slope of the line is (-9-5)/(-12-8) = 7/10
y - 5 = 7/10(x - 8)
10y - 50 = 7(x - 8)
10y - 50 = 7x - 56
7x - 10y = -50 + 56
7x - 10y = 6.
Explanation:
Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).
7x - 10y = 3
7*8 - 10*5 = 3
56 - 50 = 3
6 = 3
We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.
If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5
Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.
In the Diagram below DE≅AE ,BA∥CE
, CB∥DA
and m∠C=65∘
Find m∠BAE
Answer:
∠ DAE = 130°
Step-by-step explanation:
ABCD is a parallelogram ( opposite sides are parallel )
The opposite angles of a parallelogram are congruent , then
∠ BAD = ∠ BCD = 65°
∠ ADE = ∠ BAD = 65° ( alternate angles )
Since DE = AE then Δ ADE is isosceles with 2 base angles congruent, that is
∠ DAE = ∠ ADE = 65°
Then
∠ BAE = ∠ BAD + ∠ DAE = 65° + 65° = 130°
