Note that when a number is to the power of 2, just multiply the number to itself once.
(-10)^2 = (-10)(-10)
(-10) x (-10) = 100
(Note that two negatives, when multiplied, will result in a positive answer)
100 is your answer

Answer:
x = 1 and y = -4
Step-by-step explanation:
It is given that,
-2x = 2 + y
-2x - y = 2 ---(1)
-6x - y = -2 ----(2)
<u>To find the solution of equations</u>
Step 1: Subtract eq(2) from eq(1)
-2x - y = 2 ---(1)
<u>-6x - y = -2 </u> ----(2)
4x + 0 = 4
x = 4/4 = 1
Step 2: Substitute the value of x in eq (1)
-2x - y = 2 ---(1)
-2*1 - y = 2
-2 - y = 2
y = -2 - 2 = -4
Therefore x = 1 and y = -4
Let's write down key points of the word problem: Y = Kx
Y = Total amount of money earned
X = # of hours worked
We have the pay rate, which is equal to $9.60 per hour.
As a result, we can determine that the <em>pay rate</em> multiplied by the <em>number of hours</em> she worked is equal to the total amount of money earned at that job.
For example, if you earn 14 dollars an hour and work for 3 hours, you will earn a total of $42 (14 × 3).
In this case, multiple the pay rate by the number of hours worked to find the total pay. As a result:
Y = 9.60x
