Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite.
This is one of those times as well. the opposite of ^2 = square root.
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.

Write an equation for the line that passes through (0, 1) and has a slope of 2 (in point-slope form).

<u>Point-slope form</u>:-

Substitute 1 for y₁, 2 for m, and 0 for x₁:-
So we conclude that Option B is correct.
<h3>Good luck.</h3>

(-1) to the power of an even number is +1.
(-1) to the power of an odd number is -1.
Since 50 is an even number, (-1)⁵⁰ = 1.

10 ton = 20,000 pounds
