Answer:
Step-by-step explanation:
given are four statements and we have to find whether true or false.
.1 If two matrices are equivalent, then one can be transformed into the other with a sequence of elementary row operations.
True
2.Different sequences of row operations can lead to different echelon forms for the same matrix.
True in whatever way we do the reduced form would be equivalent matrices
3.Different sequences of row operations can lead to different reduced echelon forms for the same matrix.
False the resulting matrices would be equivalent.
4.If a linear system has four equations and seven variables, then it must have infinitely many solutions.
True, because variables are more than equations. So parametric solutions infinite only is possible
Answer:
Step-by-step explanation:
(x+2)/2 = 0
x + 2 = 0
x = -2
(y - 3)/2 = 2
y - 3 = 4
y = 7
(-2, 7)
F(-2) is the f(x) when x is -2. From the table, it is 1.
<h3><u>Answer: 6 weeks.</u></h3><h2>Your explanation</h2>
You want to take 11 and multiply 11 by 6 and get 66. Then add 66 and 30 and get 96. That's more then enough for the skateboard. 5 weeks will only equal 85, so 6 weeks is the least you can do.
