Answer:
x = 11
Step-by-step explanation:
Equation:
(5x+1) + (12x-8) = 180
You are doing this because both sides on a straight line add up to 180 degrees. The two angles would add up to 180 degrees since they are on the one side of the line.
Simplifying:
(5x+12x) + (1-8) = 180
Add your common variables together; keep in mind that variables are placed before numbers.
Adding:
17x-7 = 180
Process:
To do this, you are going to simply do the opposite operation for the number without the variable on both sides of the equal sign.
17x - 7 = 180
+ 7 + 7
------------------
17x = 187
----- ------
17 17
x = 11
You divided by 17 on both sides because you needed to get the x variable by itself. Hope this helped! :)

An electrician charges $45 for each home visit plus $19.95 every hour he spends working. Which sentence could be used to find C, the cost in dollars for a house visit and h, hours of work ? F. C = 45 + 19.95h G. C = 45h + 19.95 H. C = (45 + 19.95)h J. C = (45 - 19.95)h
Answer:
C= 45 + 19.95h
Step-by-step explanation:
45 for each home vist means one time payment
19.95 ever hour means you are charged 19.95 every hour
H= hour

Find m RS
S
(6x-28)
(4x+ 20)
Answer:
arc RS = 116°
Step-by-step explanation:
Since the 2 chords are congruent then their minor arcs are congruent, that is
SR = TU, substitute values
6x - 28 = 4x + 20 ( subtract 4x from both sides )
2x - 28 = 20 ( add 28 to both sides )
2x = 48 ( divide both sides by 2 )
x = 24
Then
arc RS = 6x - 28 = 6(24) - 28 = 144 - 28 = 116°

What type of angle is ∠1?
obtuse
right
acute
straight
Answer:
acute angle
Step-by-step explanation:
acute angle because it is under 90°
If the angle measure is less than 90 degrees then it's acute, if it is equal to 90 degrees it's right or square, if it's more than 90 degrees it's obtuse, and if it's equal to 180 degrees it's a straight angle but in this case it's straight and obtuse since 180 is greater than 90.

Is a proportional function f(x) = 5x linear? Why or why not? Explain with an example.
Given two variables x and y, y is directly proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that
y = kx,
The relation is often denoted, using the ∝ symbol, as
y ∝ x
in this case k = 5/1

Given that cos 27° = 0.891, enter the sine of a complementary angle.
sin
9514 1404 393
Answer:
sin(63°) = 0.891
Step-by-step explanation:
The cosine of an angle is the sine of its complement. The angle with a sine of 0.891 is 90° -27° = 63°.
sin(63°) = 0.891
(-7,14),(-14,3) slope
Answer:
the slope of the line that lies on those two points is 11/7
Step-by-step explanation:
insert the first point into y=mx+b
14=(-7)m+b
----------------
Do it again with the other point
3=(-14)m+b
-------------
Now put both equations in a system of equations
14=(-7)m+b
3=(-14)m+b
solve for m and b
m=11/7 and b=25
y=11/7x+25
m=slope
b=y-intercept

Explain what it means for x and y to vary directly
Answer:
(Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

Question:
Which equation represents a proportional relationship that has a constant of proportionality equal to 4/5
Answer:
[tex]y = \frac{4}{5}x[/tex]
Step-by-step explanation:
Required
Equation with 4/5 as its constant of proportion
Two proportional quantities x and y have the following relationship:
[tex]y = kx[/tex]
Where k is the constant of proportion.
In this case:
[tex]k = \frac{4}{5}[/tex]
So.
[tex]y = kx[/tex] becomes
[tex]y = \frac{4}{5}x[/tex]
Hello
Can you help me to do these two exercises please I block on those please it is on the derivatives of a number
Thank you so much in advance!!!
Answer:
First rememeber that if we have a function like:
g(x) = x^n
then:
dg(x)/dx = g'(x) = n*x^(n - 1)
And also if we have:
g(x) = f(x) + h(x)
then:
dg(x)/dx = g'(x) = f'(x) + h'(x)
1) We have the function f(x) = (x + 1)^2
We can rewrite this as:
f(x) = x^2 + 2*x + 1
Using both things written above, we know that:
f'(x) = 2*x + 1*2 = 2*x + 2
And we want to find f'(-2), so we only need to evaluate the above function in x = -2, this is:
f'(-2) = 2*-2 + 2 = -4 + 2 = -2
f'(-2) = -2
b) I suppose that this refers to the inverse function of f(x)
An inverse function is such that:
g( f(x)) = x
f( g(x)) = x
For f(x) = (x + 1)^2
The inverse will be something that first cancels that square, and then subtracts 1.
Then:
g(x) = √x - 1
if we evaluate this in f(x) we get:
g( f(x)) = √(f(x)) - 1 = √(x + 1)^2 - 1 = (x + 1) - 1 = x
Then the inverse function of f(x) is:
g(x) = √x - 1
This can also be written as:
g(x) = x^(1/2) - 1
Then the derivative of this will be:
g'(x) = (1/2)*x^(1/2 - 1) = (1/2)*x^(-1/2) = (1/2)*(1/√x)

Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1 and 3 over 4 pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?Mrs. Humble is filling bags with peanuts to give as gifts. Each bag will contain 1\frac{3}{4} pounds of peanuts. The peanuts cost $5.00 per pound. How much will the peanuts in one bag cost?
Answer:
$8.75
Step-by-step explanation:
STEP TO TAKE TO DETERMINE THE ANSWER
Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5
[tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]
[tex]\frac{7}{4}[/tex] × 5 = [tex]\frac{35}{4}[/tex] = [tex]8\frac{3}{4}[/tex] = $8.75

The no of three-pointer questions is 35 and the no of six-pointer questions is 15.
What is equation?A formula known as an equation uses the equals sign to denote the equality of two expressions.
Given:
The total no of questions = 50,
The total marks in the test = 195.
According to the question, the equation will be,
3x + 6y = 195 and x + y = 50
Here, x is the no of three mark question and y is the no of six marks question.
Solve the equation by elimination method, and we get,
x = 35 and y = 15
Therefore, the no of three-pointer questions is 35 and the no of six-pointer questions is 15.
