Answer:
2(3s-14)Step-by-step explanation:
Given the angles ∠ABF=8s-6, ∠ABE = 2(s + 11), we are to find the angle ∠EBF. The following expression is true for the three angles;
∠ABF = ∠ABE + ∠EBF
Substituting the given angles into the equation to get the unknown;
8s-6 = 2(s + 11)+ ∠EBF
open the parenthesis
8s-6 = 2s + 22+ ∠EBF
∠EBF = 8s-6-2s-22
collect the like terms
∠EBF = 8s-2s-22-6
∠EBF = 6s-28
factor out the common multiple
∠EBF = 2(3s-14)
Hence the measure of angle ∠EBF is 2(3s-14)
Given a circle with endpoints of a diameter at –10 – 1i and 6 + 11i, answer the questions below. 1. The center of the circle is at ---+ --- i.
The center of the circle is at -2 + 5i.
What are Complex Number?Complex Numbers. Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota."
Complex numbers are numbers that consist of two parts — a real number and an imaginary number.
Given:
Diameter = –10 – 1 i = (- 10, - 1)
6 + 11 i = (6, 11)
Given that we are aware that these are the diameter's endpoints, it follows that the circle's center is the place that lies midway between the endpoints.
Then,
x = (-10 + 6) / 2
= - 4 / 2
= -2
y = (- 1 + 11) / 2
= 10 / 2
= 5
Hence, the center is located at (- 2, 5).

First you have to split the shape into 2. I split the box so that the little one's length is Z and width is x. Find the area of both boxes:
Box 1:
Z x X = ZX
Box 2:
Y x (Z + X) = Y(Z + X)

Give the equation of a line that goes through the point ( − 24 , 2 ) and is perpendicular to the line 8 x + 3 y = − 6 . Give your answer in slope intercept form
Answer:
[tex]y=\frac{3}{8}x+11[/tex]
Step-by-step explanation:
To find a line that is perpendicular to 8x + 3y = -6 and goes through (-24, 2), lets first find what the line's slope would be.
We can find this by finding the slope of 8x + 3y = -6 and taking the negative reciprocal of it.
We can find the slope of that line by putting it in slope-intercept form:
8x + 3y = -6
Subtract 8x from both sides.
3y = -6 - 8x
Divide both sides by 3.
[tex]y=-\frac{6}{3}-\frac{8}{3}x[/tex]
[tex]y=-\frac{8}{3}x-2[/tex]
So the slope of that line would be -8/3.
The negative reciprocal of -8/3 would be 3/8.
Now we know that the new line would have to pass through the point (-24, 2). We can use this point and write the equation in point-slope form:
[tex]y-2=\frac{3}{8}(x+24)[/tex]
Now lets change this into slope-intercept form. Add 2 to both sides.
[tex]y=\frac{3}{8}(x+24) +2[/tex]
Distribute the 3/8.
[tex]y=\frac{3}{8}x+9+2[/tex]
Simplify.
[tex]y=\frac{3}{8}x+11[/tex]
And now we have our equation in slope-intercept form.
I hope you find this helpful.
What is the equation for the kind of reflection?
Answer:
A vertical reflection is given by the equation y=−f(x) y = − f ( x ) and results in the curve being “reflected” across the x-axis. A horizontal reflection is given by the equation y=f(−x) y = f ( − x ) and results in the curve being “reflected” across the y-axis.

Answer:

Step-by-step explanation:
Tony will donates $3000 after 5 years.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Donated amount= $1000
Tony is able to donate 3/2 times the amount that Theresa donates.
let Theresa donates x dollar each year
So, x+ 3/2x = 1000
5x/2 = 1000
5x = 2000
x= 400
Thus, Tony donate = 3/2 x 400 = $600
Hence, After 5 years Tony will donate= 600 x 5= $3000

Problem 2
Plot point L anywhere that isn't on segment JK. Draw a line through point L. I find it helps to make the lines parallel.
Next, use a compass to measure the width of segment JK. Keeping this same width, transfer the nonpencil end of the compass to point L. Draw an arc that crosses the line through L.
Mark this intersection point M. Lastly, use a pen or marker to form segment LM and erase everything else of that line.
======================================================
Problem 3
The ideas of the previous problem will be used here. We copied segment JK to form congruent segment LM. So JK = LM.
The same steps will be used to form segment GN where GN = EF. In other words, segment GN is a perfect copy of segment EF.
If you repeat these steps again, you'll get another segment of the same length. This segment goes from point N to point H. So NH = GN = EF
Then we can say,
GH = GN + NH
GH = EF + EF
GH = 2*EF

Evaluate the function f(x)=3x+12 with x+6.
f(x+6) = 6x + 60
f(x+6) = 2x - 30
f(x+6) = 3x + 30
f(x+6) = 30
Answer:
f(x+6)= 3x + 30
Step-by-step explanation:
Whenever you have to evaluate a function with a certain value, replace the variable x with a certain value. In this case, substitute x with the value of (x+6). You get the equation f(x+6)= 3(x+6) + 12, which simplifies into f(x+6)= 3x + 18 +12, which further simplifies into f(x+6)= 3x + 30.

Decide whether 0 is a solution of the inequality: a.) 2x – 1 9 c.) x – 3 > 1
Step-by-step explanation:
How to check a solution: Just as you can check the solution to an equation, you can check a solution to an inequality. First, you check the end point by substituting it in the related equation. Then you check to see if the inequality is correct by substituting any other solution to see if it is one of the solutions.
How to tell if its true or false: An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 - 12 > 5 + 2 is a true statement. 1 + 3 < 6 - 2 is a false statement.

Given f (x) = 3x - 8 find x if f(x) = -14
Answer:
[tex]x=-2[/tex]
Step-by-step explanation:
So we have the function:
[tex]f(x)=3x-8[/tex]
And we want to solve for x if f(x) is -14.
So, substitute -14 for f(x):
[tex]-14=3x-8[/tex]
Add 8 to both sides:
[tex]-6=3x[/tex]
Divide both sides by 3:
[tex]x=-2[/tex]
And we're done!
Answer:
The value of x is -2 .
Step-by-step explanation:
You have to solve it by doing comparison :
[tex]f(x) = 3x - 8[/tex]
[tex]f(x) = - 14[/tex]
[tex]3x - 8 = - 14[/tex]
[tex]3x = - 14 + 8[/tex]
[tex]3x = - 6[/tex]
[tex]x = - 6 \div 3[/tex]
[tex]x = - 2[/tex]
