Answer:
f(a)=3(a+2)-2
f(4)=3(4+2)-2
f(4)=3(6)-2
f(4)=18-2
f(4)=16
Hope this helps!
Answer:
f(4)= 16
Step-by-step explanation:
f(4)= 3(a + 2) -2
f(4)= 3(4 + 2) -2
f(4) = 3(4) + 3(2) -2
f(4)= 12 + 6 -2
f(4)= 18-2
f(4)= 16

Using the distance formula
√(x2 - x1)² + (y2 - y1)²
When given vertices x1, y1, and x2, y2
We find the length of each side
For E(10,4), F(16,4)
√(16 - 10)² + (4 - 4)²
= √6²
= √36
= 6 units
F(16,4), G(16,10)
= √(16 - 16)² + (10 - 4)²
= √6²
= √36
= 6 units
G(16,10) and H(10,10)
= √(10 - 16)² + (10 - 10)²
= √-6²
= √36
= 6 units
E(10,4), and H(10,10)
It is a square because all the sides are equal

For the function, f(x)=-8, find:
f(3)
A) f(3)=-5
B) f(3) does not exist
C) f(3)=-8
D) f(3)=3
E) f(3)=-24
The value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
For the function, f(x) = -8
f(x) = -8
For all values of x:
The above function can be written as follows:
f(x) = -8x⁰
PLug x = 3 in the function:
f(x) = -8(3)⁰
f(x) = -8
Thus, the value of the f(3) is -8 or f(3)=-8 if the equation of the function f(x) = -8(3)⁰ or f(x) = -8 option (C) is correct.

Given the system of equations:
2x + 2y = 12
X-y= 2
What is x equal to?
8
4
2
1
-2
Answer:
x=4
y=2
Step-by-step explanation:
2x+2y=12
x−y=2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+2y=12,x−y=2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+2y=12,2x+2(−1)y=2×2
Simplify.
2x+2y=12,2x−2y=4
Subtract 2x−2y=4 from 2x+2y=12 by subtracting like terms on each side of the equal sign.
2x−2x+2y+2y=12−4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
2y+2y=12−4
Add 2y to 2y.
4y=12−4
Add 12 to −4.
4y=8
Divide both sides by 4.
y=2
Substitute 2 for y in x−y=2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2=2
Add 2 to both sides of the equation.
x=4
The system is now solved.
x=4,y=2
Correct choice is B) x=4.
answer is 4
because y=2 then you subsistute it in and then you find X
x-y=2 turns to x=y+2 then you subsistute that into x of the equation 2x+2y=12 which then is 2(y+2)+2y =12 and you should get y=2 then you grab the other equation x-2=2 and you should get x=4

triangle ABC is similar to triangle EHG , find the measure of angle EHG .
Answer:
[tex]\angle EHG = 80[/tex]
Step-by-step explanation:
Given
ABC ∼ EHG
See attachment
Required
Determine [tex]\angle EHG[/tex]
First, we calculate x in ABC
[tex]x + 2x + 60= 180[/tex]
[tex]3x + 60= 180[/tex]
[tex]3x = 120[/tex]
[tex]x = 40[/tex]
The corresponding angle to [tex]\angle EHG[/tex] is [tex]\angle ABC[/tex]
and
[tex]\angle ABC = 2x[/tex]
[tex]\angle ABC = 2 * 40[/tex]
[tex]\angle ABC = 80[/tex]

Kevin is doing an experiment where he flips a fair coin 20 times and analyzes the results. The coin has come up heads the first 19 trials. What is the conditional probability that the next flip will come up tails, given that the previous 19 flips were heads? Explain why your answer makes sense.
Answer:
it's still 50%
each flip is an independent probability. what happened the first 19 times is irrelevant, because it's still a 50-50 chance on any independent flip.

Answer:
The slope is -3.75 or -15/4.
Step-by-step explanation:
The formula for slope is the change in y over the change in x.
To do this, you subtract 7-3 to get you 4 on the bottom of the fraction and -7-8 which is -15.
So pretty much, you get -15/4. :)

Answer:
All the given measurements of the right triangles are correct
Step-by-step explanation:
Check the three diagram and determine the three sides of the right triangle that correspond to Pythagoras triple.
For the first triangle:
12² + 5² should be equal to 13²
144 + 25 = 13²
169 = 13²
Thus, 5, 12 and 13 corresponds to three sides of right triangle.
For second diagram;
24² + 7² should be equal to 25²
576 + 49 = 25²
625 = 25²
Thus, 7, 24 and 25 corresponds to three sides of right triangle.
For third diagram;
3² + 4² should be equal to 5²
9 + 16 = 5²
25 = 5²
Thus, 3, 4 and 5 corresponds to three sides of right triangle.
Simplify the following : x^2y^-3 / x^5y^2
Answer:
Step-by-step explanation:
[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\\frac{x^{2}y^{-3}}{x^{5}y^{2}}=x^{(2-5)}*y^{(-3-2)}\\\\ = x^{-3}*y^{-5}\\\\=\frac{1}{x^{3}y^{5}}[/tex]
Remember that exponents (or powers) of the same basis can be divided by subtracting the exponents. For example [tex]\frac{x^n}{x^m} =x^{n-m}[/tex]
Using this information, we can easily rearrange our equation to look like this:
[tex]\frac{x^2}{x^5} \frac{y^{-3}}{y^2}[/tex]
Now that the basis are the same, we can conveniently subtract the exponents to get the following result:
[tex]x^{-3}y^{-5}[/tex] or [tex]\frac{1}{x^3y^5}[/tex]. And that's the final answer.

O The domain and range of the graph are the same.
O The range of the graph is all real numbers.
Answer:
B
The domain of the graph is all real numbers less than or equal to 0.
Step-by-step explanation:
just took the test
The statement for the graph will be the domain of the graph is all real numbers less than or equal to 0.
Given,
Graph of function f(x) = √-x
Here,
If there is a function f(x) = √-x , then the domain is the set of all values that x can take and the range is the set of all the values that y can take for the function to exist.
Thus, the domain of the graph is all real numbers less than or equal to 0.
Therefore option B is correct.

1. Rafael stands 55 feet from the tower and uses a clinometer to measure the angle of elevation to the
viewing platform as 37º. How far up the tower is the viewing platform?
Answer:
41.4feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Given the following
Distance of Rafael from the tower = 55feet = Adjacent
Angle of elevation = 37degrees
Required
Height of the tower = Opposite
Since Tan theta = opp/adj
Tan 37 = x/55
x = 55tan37
x = 55(0.7536)
x = 41.4
Hence the tower is 41.4feet up the viewing platform

(101)² solve it using identities
Answer:
10201
Step-by-step explanation:
=(101)²
=(100+1)²
={100²+2(100)(1)+1²} [(a+b)²=a²+2ab+b²]
=10000+200+1
=10201
Solution :-
Given,
(101)^2We need to solve it using identities.
>> (100 + 1)^2
As we know that,
>> (a + b)^2 = a^2 + b^2 + 2ab
Here,
a = 100 b = 1Using the identity we gets,
>> (100)^2 + (1)^2 + 2(100)*(1)
>> 10000 + 1 + 200
>> 10000 + 201
>> 10201
