Answer:
y=x-3
Step-by-step explanation:
To find slope, use m=y2-y1/x2-x1, using values of x and y from two different points. Once you have found slope, take another point and use the point-slope equation y-y1=m(x-x1) and substitute in slope for m and the point for x1 and y1. Isolate y by subtracting y1 from both sides.
Answer:
- movie: $1.25
- video game: $5.25
Step-by-step explanation:
Let m and v represent the rental costs of movies and video games, respectively. The two rentals can be described by the equations ...
5m +3v = 22
2m +6v = 34
We notice that the coefficient of v in the second equation is 2 times that in the first equation. This will make it easy to eliminate v as a variable.
Subtracting the second equation from 2 times the first gives ...
2(5m +3v) -(2m +6v) = 2(22) -(34)
8m = 10 . . . . . . . . . . . simplify
m = 10/8 = 1.25 . . . . . divide by the coefficient of m
Using this in the second equation, we can find v:
2(1.25) +6v = 34 . . . . .substitute for m
6v = 31.50 . . . . . . . . . subtract 2.50
v = 5.25 . . . . . . . . . . . divide by the coefficient of v
The rental cost for a movie is $1.25; for a video game it is $5.25.
Additive Inverse of -33
<h2>༆ANSWER:</h2>
—————————————————
- The additive inverse of -33 is 33.
<h3>Remember!</h3>
»The opposite of the given integer is
called its additive inverse. The sum of a
number and its additive inverse is zero. For example, the additive inverse of -4 is 4, so when you add the two integer they sum will be zero.
Answer:
Solve for n:
28 = n
Hint: | Reverse the equality in 28 = n in order to isolate n to the left hand side.
28 = n is equivalent to n = 28:
Answer: n = 28
Step-by-step explanation:
Here we go......
-2= 5x-1
+1 +1
-1/5=5x/5
- 1/5
