Answer:
The inverse function is f(x) = (x + 7)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x -7
x = 2f(x) - 7
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) - 7
x + 7 = 2f(x)
(x + 7)/2 = f(x)
Answer:
0.44
Step-by-step explanation:
-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2
Combine like terms
-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2
2x^2 - 1y^2 + 5xy - 2y
Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1
2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)
Simplify:
0.5 - 0.01 - 0.25 + 0.2
0.5 + 0.2 - 0.01 - 0.25
0.7 - 0.26
0.44
Answer:
Yes
Step-by-step explanation:
x , y
(-3 , 0)
plug in the numbers
2(-3) + 6(0) = -6
-6 = -6
