Answer:
The amount of money in dollars that Rob owe his father is -$18
Step-by-step explanation:
From the given information:
Rob borrows $15 from his father and then he also borrows $3 more.
Thus, the amount he owes is father is now:
- $15 - $3 = - $18 Since we are using negative integers.
The amount of money in dollars that Rob owe his father is -$18
Answer:
-2, -6
Step-by-step explanation:
using cramer rule
5 -3
-2 -1
calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11
using cramer rule
to calculate x we change the coefficient of x with the answer (8,10)
8 -3
10 -1
we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22
to calculate x
22/-11= -2
to calculate y we change the coefficient of y with the answer (8,10)
5 8
-2 10
we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66
to calculate y
66/-11= -6
