The answer is 3(x minus 2) + d = 2x-6 because...
3 x- 2+ x = 2x - 6 —-> simplify 3x + x
2x-2= 2x - 6 ——> subtract 2x from both sides
and you get
-2=6, so the answer is not solution since -2 cannot equal 6.
Hope this helps!
Answer:
x>-1
Step-by-step explanation:
-2x+5<7
subtract 5
-2x<2
divide by -2, the sign changes
x>-1
Answer:
A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.
Step-by-step explanation:
Given that u4 is not a linear combination of {u1,u2,u3}
This means there is no possibility to write u4 = au1+bu2+cu3 for three scalars a,b,and c.
This gives that
This implies that these four vectors are not linearly dependent but linearly independent.
Hence option a is right.
A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.
Answer:
More student's prefer PE. See numbers below.
Step-by-step explanation:
Remark
You have to assume that the choices are mutually exclusive. That means that if a student likes PE he can't choose Social Studies. If he likes Social Studies best then he doesn't like PE best.
Begin by finding out what 75% of the students are.
75/100 * 20 = 75 * 20/100 = 1500/100 = 15.
Fifteen students prefer PE. Only 4 like Social Studies.
15 > 4
