Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
Answer: (inputs will be the x's and outputs will be the y's like this -> (x,y))
(-3, 0)
(0, -4)
(2, 3)
(6, 5)
Answer: B
Step-by-step explanation:
To find (f-g)(x), you simply subtract f(x) and g(x). With the given functions of f(x) and g(x), we can directly subtract them.
f(x)-g(x) [plug in f(x) and g(x)]
-3x+2-x³ [rewrite in the correct order]
-x³-3x+2
Since there are no like terms for us to combine, B is our correct answer.
Answer:
43
Step-by-step explanation:
just go backwards so multiply 9 by 4
36
then add 7
43
then to check go 43-7
36-1/4
9
Simply plug in -15 for x in our given equation.
-x + 2y = -1
-(-15) + 2y = -1
Simplify.
15 + 2y = -1
Subtract 15 from both sides.
2y = -1 - 15
Simplify.
2y = -16
Divide both sides by 2
Y = -8
