Answer: Aaron was at the sitter for 5 hours
Step-by-step explanation:
12x + 10 = 58
the 12x is for each hour after the first hour and the 10 is the first hour
-10 from each side
12x = 48
/12
x = 4
4 additional hours plus the original hour
Answer:
True, True, False, True, False for part 1
Step-by-step explanation:
Make me brainliest
Answer and Step-by-step explanation:
A) False, take (1,-1) and (1,1) both in V, but the sum (2,0) is not
B) True, if A,B are symmetric then A+kB is symmetric as well for k scalar, and zero matrix is symmetric.
C) True. The zero polynom is in V and P+kQ verifies (P+kQ)(0)=P(0)+kQ(0)=0
D) True. zero is solution and f+kg is since all coefficients are linear.
E) True, same than C)
F) False , the zero function doesn't verify that ( and the closure for sum will fail anyway 4+4=8)
G) False, the zero function fail to satisfy this ODE
Answer:
y=3
x=-4
Step-by-step explanation:
-x+2y=10
*3
-3x+6y=30,
then add it with 3x+5y=3,
3x+5y=3
-3x+6y=30, would be...
0x+11y=33,
y=3,
x=-4
