Answer:
You would just plug in the x’s for the equations above and that will equal your x
Step-by-step explanation:
for example x=1
the equation is x+5
so y equals 1+5=6
y=6
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:
x=60
Step-by-step explanation:
This is a parallelogram.
For a parallelogram,
sum of angles in one side is 180.
we know, in a parallelogram,
the consecutive angles are supplementary or
their sum is 180.
So, we get,
x+33+87=180
or, x+120=180
subtracting 120
x+120-120=180-120
or, x=60
