Answer:
a. (6x-5)^2
b. 4x(2x^2+1)
c. -4(x-12)(x+3)
d. (2x+1)(4x-3)
Step-by-step explanation:
Answer:
2294
Step-by-step explanation:
Answer:
4.
Step-by-step explanation:
f^-1(x) is the inverse of f(x). That means that f(x) = 2x - 6 becomes...
x = 2y - 6
2y - 6 = x
2y = x + 6
y = 1/2x + 3.
When x = 2...
y = 1/2(2) + 3
= 1 + 3
= 4.
Hope this helps!
Answer:
J. (2, -3)
Step-by-step explanation:
1. Substitute y = x - 5 in for y in the other equation:
5x + 2(x - 5) = 4
2. Simplify:
5x + 2x - 10 = 4 (distributed the 2)
7x - 10 = 4
3. Isolate for x:
7x - 10+10 = 4+10
7x = 14
7x/7 = 14/7
x = 2
4. Plug the new x value into an equation and solve for y:
y = 2 - 5
y = -3
hope this helps!
