Answer:
47-Step-by-step explanation:
X=121 because they are vertical angles
48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3
A'B'C' is larger than ABC, so the scale factor would be a whole number, scale factor of 2.
A'B'C'is also a morrir image of ABC, notice on ABC A is on the left and B is on the right, but on A'B'C', B" is on the left and A' is on the right.
This means it was reflected across the Y axis.
The first answer is the correct one.
Answer:
(1)
Multiplying by 3 both sides of the equality you get that

3u is in the Span of the vectors
.
(2)
That's not true, consider the following counter example.

is a linear combination of
but is NOT a linear combination of 
Step-by-step explanation:
(1)
As the hint indicates, you know that

Then, if you multiply both sides of the equality by 3, you get that

And that's it. 3u is in the Span of the vectors 
(2)
That's not true, consider the following counter example.

is a linear combination of
but is NOT a linear combination of 
Answer:
No
Step-by-step explanation:
plug (6,3) into the given equation to find out
3 = 4(6-5)
3 = 4(1)
3 = 4
since 3 does not equal 4, the point (6,3) does not satisfy the equation y=4(x-5)
