Answer:
x=7
Step-by-step explanation:
This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:
6x-7=4x+7
From there you can solve for x. I will write my process here:
2x-7=7
2x=14
x=7
Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!

Step-by-step explanation:
When x = 2 and y = -1,
(x + y)³ - (x - y)³
= (2 - 1)³ - [2 - (-1)]³

A school conducts 27 tests in 36 weeks. Assume the school conducts tests at a constant rate. What is the slope of the line that represents the number of tests on the y-axis and the time in weeks on the x-axis?
Answers
Answer:
The slope is equal to [tex]\frac{3}{4}[/tex].
Step-by-step explanation:
In order to solve this question we need to know that.......
[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]
Where "m" = slope," [tex]y_{2}-y_{1}[/tex]" = first difference, and [tex]x_{2} - x_{1}[/tex] is the difference of the x values of the two points that we chose to fid the slope.
(If you don't understand something I would recommend to read about first differences and how we can use the first differences to find the slope).
Now we need to find two points on the line. One of them is already given to us and it is (36,27). In order to find the second one we will have to find a point with "x" and "y" values that have the same relation ship to each other as the point (36,27). We can do that by doing the following
[tex]\frac{x/a}{y/a} =\frac{x_{1} }{y_{1} }[/tex]
In this case a any common factor of "x" and "y" except 1. So now we can do the following...
[tex]\frac{36}{27} = \frac{36/9}{27/9} = \frac{4}{3}[/tex]
Now we know that another point on this line is (4,3).
Now all we have to imagine (36,27) as ([tex]x_{2} ,y_{2}[/tex]), and imagine (4,3) as [tex](x_{1} , y_{1})[/tex]. so now......
[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{27 - 3}{36-4} = \frac{24}{32} = \frac{3}{4}[/tex]

Total amount of lemonade / number of persons
3 litres / 8
= 0.375 litres
Each person receives 0.375 litres of lemonade

Write the equation of a line parallel to y=2x+2 that passes through the point (-1, -7)
Answers
Answer: y=2x-5
Step-by-step explanation:
To find the line that is parallel to y=2x+2, we know the slope must be 2. Parallel lines NEVER touch. That tells us that the slope must be 2. Now, all we have to do is to plug in the point to find the y-intercept.
-7=2(-1)+b [multiply]
-7=-2+b [add both sides by 2]
b=-5
With the y-intercept, we can find the parallel line.
y=2x-5
