Answer:
[tex]-\sqrt{105}=10.2[/text]
Step-by-step explanation:
We are asked to find the value of [tex]-\sqrt{105}[/text] to the nearest tenth.
Using calculator we find the value if [tex]-\sqrt{105}[/text] which comes out to be 10.24
Hence
[tex]-\sqrt{105}=10.2[/text]
Rounded to nearest tenth decimal .
Do lines A and B intersect?
You must show all your working.
The lines 2y = 3x + 8 and y = 2x + 4 will intersect at (0, 4).
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
A and B are straight lines.
Line A has equation 2y = 3x + 8 ....1
Line B goes through the points (-1,2) and (2,8). Then the equation of the line will be
y - 2 = [(8 - 2) / (2 + 1)] (x + 1)
y - 2 = 2(x + 1)
y = 2x + 2 + 2
y = 2x + 4 ...2
From equations 1 and 2, then we have
2(2x + 4) = 3x + 8
4x + 8 = 3x + 8
x = 0
Then the value of y will be
y = 2 (0) + 4
y = 4
The lines 2y = 3x + 8 and y = 2x + 4 will intersect at (0, 4).

Answer:
2 x 2 x 2 x 2 x 2 x 2 x 2 = 128
OR
2^7
Step-by-step explanation:
2 is the only prime number you can multiply to get 128.
as such your answers are :
2^7
or
2 x 2 x 2 x 2 x 2 x 2 x 2.
(if you don't know yet, 2^7 is just a simple way to say 2 times itself 7 times.)
