Answer:
Step-by-step explanation:
4x² - 7x + 3 = 4x² - 4x - 3x + (-3)*(-1)
= 4x*(x - 1) - 3(x - 1)
= (x-1) (4x - 3)
Answer:
x=120
y=60
Step-by-step explanation:
So it states that this is an equilateral triangle which means that all of the angles in this triangle or the same
the sum of all the angles is equal to 180 so to find y we divide 180 by 3
180/3=60
y=60
we notice that its supplementary to the angle that measures 60 and supplementary angles add up to equal 180 so to find x we subtract 60 from 180
180-60=120
x=120
Ok now this one i am 100% confident in my answer
Answer: trivial solution is the only solution to Ax = 0, therefore columns must be linearly independent.
Step-by-step explanation: Recall that the columns of A are linearly independent if and only Ax = 0 had only the trivial solution. Since Ax = b has at most one solution, therefore the only solution to Ax = 0 is the trivial solution and the column vectors must be linearly independent.
0.000576 is the right awnser
Replace x with -2
2 * 1/9= 2/9
