Answer: 3x -6 (x+2)-(x+5)
Step-by-step explanation:
Distribute the Negative Sign:
=3x−6(x+2)+−1(x+5)
=3x+−6(x+2)+−1x+(−1)(5)
=3x+−6(x+2)+−x+−5
Distribute:
=3x+(−6)(x)+(−6)(2)+−x+−5
=3x+−6x+−12+−x+−5
Combine Like Terms:
=3x+−6x+−12+−x+−5
=(3x+−6x+−x)+(−12+−5)

Find the equation of a line parallel to the line 2x-y-9=0 and passing through the point of intersection of the lines 5x+y+4=0 and 2x+3y=1
Answer:
[tex]y=2x-3[/tex]
Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to [tex]2x-y-9=0[/tex]
[tex]5x+y+4=0[/tex]
[tex]y= -4-5x[/tex]
substituting the value of y in [tex]2x+3y=1[/tex]:
[tex]2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1[/tex]
substituting x=-1 in y= -4-5x:
[tex]y= 1[/tex] (upon solving, you should get this)
[tex](x,y)= (-1,1)[/tex]
2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)
[tex]2x-y-9=0\\2x-9=y\\y= 2x-9[/tex]
[tex]y= mx+c\\[/tex]
-1= 2 x 1 +c
-3=c

1. daily earnings of the amusement park after one $2 increase
daily earnings before any $2 increases
number of tickets sold before any $2 increases
2. price of a ticket after x increases of $2
number of tickets sold after x increases of $2
number of tickets sold before any $2 increases
Answer:
THE COMMENT IS CORRECT
Step-by-step explanation:
Thanks, man.
Answer:

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given that, Mark makes a total of $500 for every 3 clients she acquired.
∴ To find how many clients he needs to earn $10,000 in a day we have to divide the earnings wanted by earnings per client which is,
= (10000)÷(500/3).
= 10000×3/500.
= 100×3/5.
= 300/5.

Answer:
y = -1/7x y = 2x -7Step-by-step explanation:
1. The slope of the given line is the x-coefficient, 7. The slope of the perpendicular line is the negative reciprocal of this: -1/7. Since the line goes through the origin, the y-intercept is zero.
y = -1/7x
__
2. The first part of this problem is to find the solution to the given system of equations. We can substitute for x to do that:
3(5 -y)-2y = 10
15 -5y = 10 . . . simplify
-3 +y = -2 . . . . divide by -2
y = 1, x = 4 . . . add 3 to find y; subtract y from 5 to find x
__
The second part of this problem requires we note the slope of the parallel line. It is the x-coefficient, 2. The y-intercept can be found from ...
b = y -mx = 1 -2(4) = -7
So, the desired line in y=mx+b form is ...
y = 2x -7

So I answered one of your rounding questions before. I am going to give you some math rules so that you can do it on your own.
If you are rounding to the hundreds place and the number in the tens place is 4 or less, the number in the hundreds place stays the same and the other places are 0.
If you are rounding to the hundreds place and the number in the tens place is 5 or more, the number in the hundreds place increases by 1 and the other places are 0.
The answer to your question is 400.

The measure of x is:
9 inches
Step-by-step explanation:
Perimeter = x + 2(x-4)
perimeter = 19 inches
then:
19 = x + 2(x-4)
19 = x + (2*x) + (2*-4)
19 = x + 2x - 8
19 = 3x - 8
19 + 8 = 3x
27 = 3x
27/3 = x
x = 9 inches.

How many solutions does this system of equations have? y=3x+1 y=3x+7
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
This equation has no solution.
What is the inconsistent system?An inconsistent system is a system that has no solution in any case scenario.

Three apples and six pears cost $7.44. Four apples and ten pears cost
$11.58. Find the cost of an apple.
Answer:
$0.86
Step-by-step explanation:
Let's say the cost of the apples is A and the cost of the pears is P.
3A+6P=7.44
4A+10P=11.58
Now our best bet is elimination. We have to multiply the equations (Dont' forget about both sides, otherwise it does not work!) by the least common multiple.
We want to keep the variable A, meaning we'll have to target B. The least common multiple is 30, so now we'll multiply both equations like so:
15A+30P=37.20
12A+30P=34.74
Now we subtract the second equation from the first one. We get:
3A=2.46
And we divide both sides by 3, leaving us with
A=$0.86 or 86 cents.
