Answer:
$6
Step-by-step explanation:
<span>In a survey in 2016, it was found that for 10 broad degree categories ranging from engineering to communications, projected average salary of a bachelor’s degree is </span><span>$50,556 in 2016. </span> In 2017, actual was $50,000 ($49,785, to be exact). If t$50,000 will be the basis, and the male who gets a job paying $ 40,760/yr, the difference in his yearly median income from obtaining a bachelor's degree is $9,240.
<span>His pay is 18% lower compared to the median income degree level you obtained, on a monthly basis or yearly basis</span>
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
First you need to get two similar terms to eliminate, I'll do y:
-3x + 2y = 10
-4x - 2y= -10
And then you minus
x = 20
Now you can substitute x in to one of the equations to find y:
-60 + 2y = 10
+ 60
2y = 70
÷ 2
y = 35
So your values are y = 35 and x = 20. Hope this helps!
