Answer:
y=20x+35
Step-by-step explanation:
if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
a plumber who is just starting out offers low rates to attract new customers
Plumber charges $35 to visit a client's home, plus an additional $20 per hour.
Let the charges per hour be denoted by x.
and it is given that y is cost of a visit.
We are required to write equation for cost of a visit y.
y equal to twenty x plus thirty five.
y=20x+35
Hence if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.

A line is drawn so that it passes through the points (-3, -1) and (4, 2).
a. What is the slope of the line?
b. Using the point (4, 2) and the slope found above, write the equation of the line in point-slope form.
Answer:
y - 2 3/7 (x-4)
Step-by-step explanation:
A) To find slope, use the equation:where and are the x and y values of one coordinate point , and and are the x and y values of another coordinate point . Since we are given two coordinate points, (-3,-1) and (4,2), that means we can find the slope using the slope equation.
Let's choose (4, 2) as your point and (-3, -1) as your point, but you can switch those if you want! That makes and x^1 = -3, y1 = -1 . Plug these values into the slope equation:
The slope of the line is 3/7.
B) Remember that the general equation for point-slope form is, where m = the slope, = the x value of a coordinate point on the line, and = the y value of the same coordinate point on the line.
You are given (4, 2) as one of the coordinate points. That means = 4 and = 2. We found the slope, m = in part A. Now plug these values into the general equation for point-slope form to find your point-slope form equation:
Your point-slope form equation is y - 2 3/7 (x-4).

What is the value of x?
Answer:
more ... The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
For resolve this problem I use trigonometry identities.
[tex]sin(\theta) = \frac{OP}{H}[/tex]
Where [tex]\theta[/tex] is the angle of the triangle (45), [tex]OP[/tex] is the opposite side of the angle ([tex]6\sqrt{2}[/tex]) and the [tex]H[/tex] is the hypotenuse ([tex]x[/tex]).
Replace the know values in the relation
[tex]sin(45) = \frac{6\sqrt{2}}{x}[/tex]
Isolate [tex]x[/tex] of the equation and solve
[tex]\frac{6\sqrt{2}}{sin(45)} = x\\\frac{6\sqrt{2}}{\frac{\sqrt{2}}{2}} = x\\\frac{12\sqrt{2}}{\sqrt{2} } = x\\12 = x[/tex]

A line contains the points (-3,-9) and (4,5). What is the point-slope form of the line? A. y + 9 = -2 (x + 3)
B. y - 5 = 3 (x - 2)
C. y - 9 = 2 (x + 3)
D. y + 9 = 2 (x + 3)
Answer:
D
Step-by-step explanation:
First find the slope.
[tex]Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{5-[-9]}{4-[-3]}=\dfrac{5+9}{4+3}\\\\\\=\dfrac{14}{7}=2[/tex]

Savannah decides to download some new music. she downloaded 5 albums and 7 singles, and his total was $71. The next day she purchased more music from the same retailer and downloaded 3 more albums and 6 singles for a total of $48.
Assuming that all albums and singles are the same prices, how much did she spend on each album and each single? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.
Answer:
Step-by-step explanation:
downloaded= 5 albums and 7 singles and total price is $71
Know,
album + singles = 5+7= 12
∴ price÷ from total of albums and singles
$71÷12=$5.92
per album = $5.92
per single = $5.92
Next day;
3+6=9
total price =$48
⇒ =$48÷9 = $5.3
per album= $5.3
per album= $5.3
""""" I just try to Solve """"""
Answer: Singles are $3/each and albums are $10 each.
Step-by-step explanation:
Let A and S represent the number of Albums and Singles, respectively.
We are told that:
5A + 7S = $71
and also that:
3A + 6S = $48
We have two equations and 2 unknowns. Use elimination to find the price of one and then that will tell us the price of the other. I'll choose to eliminate the A:
5A + 7S = $71
3A + 6S = $48
We can do the elimination in one of 2 ways:
1) Solve one of the equations for A or S, and substitute it in the other:
3A + 6S = $48
3A = $48 - 6S
A = ($48 - 6S)/3
Now use this definition of A in the first equation:
5A + 7S = $71
5(($48 - 6S)/3) + 7S = $71
5(($48 - 6S)/3) + 7S = $71
$80 - 10S + 7S = $71
-3S = - 9
S = $3
Now we can find A:
5A + 7S = $71
5A + 7(3) = $71
5A + 21 = $71
A = $10
======
2) We could also modify one of the equations and then subtract to eliminate a variable:
5A + 7S = $71
3A + 6S = $48
Let's multiply the second equation by -(5/3):
-(5/3)*(3A + 6S = $48)
-5A - 10S = -90
Now add this to the first equation:
5A + 7S = $71
-5A - 10S = -80
- 3S = - 9
S = $3 and therefore A = $10
