1.63 is the answer. :))))))
Answer:
No solution
Step-by-step explanation:
- 4x - 4y = 1
- 4x - 4(x + 2) = 1
- 4x - 4x - 8 = 1
- - 8 = 1
Our end result is -8 = 1. This is not true, so this system of equations have no solution.

A, you need to pay with exact change
Answer:
The vertex is (2,1)
Step-by-step explanation:
ƒ(x) = –x^2 + 4x – 3
Factor out the negative
= -(x^2 -4x+3)
Factor
What 2 numbers multiply to +3 and add to -4
-3*-1 = 3
-3+-1 = -4
f(x) = -( x-3)(x-1)
Find the zeros
0 = -( x-3)(x-1)
0 = x-3 0 = x-1
x=3 x=1
The x value of the vertex is 1/2 way between the two zeros
(3+1)/2 = 4/2 =2
To find the y value, substitute x=2 in
f(2) = -( 2-3)(2-1)
=-(-1)(1) = 1
The vertex is (2,1)
