Answer:
4+3 squared 3 equals 9.19 and 4-3 squared 3 equals -1.19
Step-by-step explanation:
We want to use the Substitution method to solve
7x - 2y = 1 (1)
x - 2y = 1 (2)
From equation (1), obtain
2y = 7x - 1 (3)
Substitute (3) into (2).
x - (7x - 1) = 1
-6x + 1 = 1
-6x = 0
x = 0
From (3), obtain
2y = 7*0 - 1 = -1
y = -1/2
Answer: (0, -1/2) or x=0, y= -1/2.
Answer:
the reciprocal is just x because x over 1 is just x

Answer:
$3,500 at 10% and $6,500 at 7%.
Step-by-step explanation:
M * 10% + (10000 - M) * 7% = 805
0.1M + 700 - 0.07M = 805
0.03M = 105
M = 3500
