Answer:
y = x + 2
Step-by-step explanation:
The expression x-2 is from the equation y = x - 2.
To find the inverse of the equation, <u>switch the "x" and "y" variables</u>, then solve or <u>isolate for "y"</u>, meaning to separate it from the other numbers.
y = x - 2 Original equation
x = y - 2 Switched "x" and "y" variables
x + 2 = y - 2 + 2 Add 2 to both sides to cancel out '-2' on the side with "y"
x + 2 = y
y = x + 2 Variable is on left side in standard formatting
To isolate, do the reverse operation for the number you want to get rid of.
On the side with "y", I wanted to get rid of '-2' so I could separate "y" from everything else. '+2' is the reverse operation for '-2'.
From this detail that is a right isosceles triangle result that the angles from the base has measure of 45 degrees
- there is given again that the length of legs is 6"
- than we drawn the height from the right angle on hypotenuse and use sin45 we get
but we need to know that 6" = 6*2,6 = 15,6 cm = 0,156 m
cos 45° = (half of hypotenuse)/6"
sqrt2 /2 = (half of hyp) /6"
half of hyp. = 6"sqrt2 /2 = 3sqrt2" so than the length of hypotenuse will be
equal 2*3sqrt2 = (6sqrt2)"
Answer:
x=13
Step-by-step explanation:
Angle A and angle B are supplementary
Supplementary angles add to 180 degrees
<A + <B = 180
7x-18 + 8x+3 = 180
Combine like terms
15x -15 = 180
Add 15 to each side
15x-15 +15 = 180+15
15x = 195
Divide by 15
15x/15 =195/15
x =13
Answer:
Slope = -2
Step-by-step explanation:
Given the two points, (-4, 10) and (0, 2), the error in the given problem is the incorrect substitution of values into the formula. It should have been formatted as follows:
Let (x₁, y₁) = (-4, 10)
(x₂, y₂) = (0, 2)
The formula for solving for the slope of the line is:
m = (y₂ - y₁)/(x₂ - x₁)
where <em>m</em><em> </em>represents the <u>slope</u> of the line.
Substitute the given values into the formula to solve for the slope:
m = (y₂ - y₁)/(x₂ - x₁)
m = -8/4
m = -2
Therefore, the slope of the line is -2.
Okay, I got you...
2) 2
3) 6
4) 33
5) 5
6) 19
No. (12+6)/2=9
and 12+6/2=15
This happens because in order of operations parentheses come first, so you would do that and get 18. Then you would divide 18 by 2 and get 9.
On the second one you would do division first (6/2) and get three, the you would add 12 and end up with 15.
Hope this helps :)
