Answer:
between 0 and 1
Step-by-step explanation:
The big key to this is that the negative sign in front of the two is NOT in parentheses along with the 2.
We follow the order of operations - PEMDAS - parentheses, exponents, multiplication and division, addition and subtraction.
So, inside the parentheses, the <u>first </u>thing we do is the <u>exponent</u>. We raise 2 to the third power and get 8.
Next, still inside the parentheses, we now multiply by negative 1. That is what putting a negative sign in front of something really is - multiplying by -1.
So now inside the parentheses, we have -8.
-8 raised to the power -2 is one over (-8) raised to the power positive 2.
That is one over 64,
That is more than zero, but less than one.
I have the math written out in an attached picture (I hate the equation writer on this website.) Haha.

The formula of linear equation is:
Where
x1 and x2: x coordinates(-1 and 3)
y1 and y2: y coordinates(-2 and 10)
m is the slope
We can then choose a point from the line to find the eqaution.
We need to first find the slope:
In this case:
In this case, as the y2 is given as 1,put (-1,-2) , and the slope(3 )into the eqaution :
y-(-2) = 3(x-(-1))
y+2 = 3(x+1)
Therefore
is the answer.
Hope it helps!

Answer:
<h2> <em><u>x = 2.82 (approx.)</u></em></h2>Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
- 356 = -77 - 99x
=> -77 - 99x = -356
=> -99x = -356 + 77
=> -99x = -279
=> x = 2.8181....
=> <em><u>x = 2.82 (approx.) (Ans)</u></em>
