Answer:
A. Span (w, y) = Span (w, x, y)
C. Span (w, x) = Span (w, x, z)
D. Span (w, x) = Span (w, z)
Step-by-step explanation:
The vectors x, y , z are non zero vectors. Vector has direction and magnitude both. For the given equation of -2x - 4y + 3z the span for w, y equals the span of w,x,y. The statements A, C and D are true and the other statements B and E are not correct. For the given equation the vector span y,z does not equals span of x,y,z.
Answer:
40
Step-by-step explanation:
Answer:
0, 3 , 8
Step-by-step explanation:
substitute n = 1, 2, 3 into the pattern rule
T₁ = 1² - 1 = 1 - 1 = 0
T₂ = 2² - 1 = 4 - 1 = 3
T₃ = 3² - 1 = 9 - 1 = 8
Answer:
m=5
Step-by-step explanation:
We can solve this by using a system of equations. The easiest way to solve this is by using substitution.
3m=19-n Subtract both sides by 19 to find n.
<u>-19 -19</u>
3m-19=-n Divide everything by -1 to make n positive.
<u>/-1 /-1</u>
n=-3m+19
Now, we can substitute n into the second equation.
2m+5(-3m+19)=30 Substitute (-3m+19) into n.
2m-15m+95=30 Simplify.
-13m+95=30 Simplify and subtract both sides by 95.
<u>-95 -95</u>
-13m=-65 Divide both sides by -13.
<u>/-13 /-13</u>
m=5
We don't need to solve for n at all, so that is the answer!
Hope this helps, and have an amazing day ♥
