Step-by-step explanation:
Sales tax = $750 × 0.08375 = $62.8125
Answer:
The table is missing in the question. The table is provided below.
Step-by-step explanation:
1. In the table, it is given the difference of high temperature. They are :
-7, -7, 2, 5, -3, -2
Now adding the differences of high temperatures and taking out its average.
-7 + (-7) + 2 + 5 + (-3) + (-2)= -12
Average : 
Thus the answer is an integer.
2. In the table, it is given the difference of high temperature. They are :
0, -3, -7, -1, 1, 0
Now adding the differences of high temperatures and taking out its average.
0 + (-3) + (-7 )+ (-1) + 1 + 0= -10
Average : 
Thus, the answer is not an integer. The answer lies between the integers -2 to -1.
Answer:
5sqrt(5) = q
-5sqrt(5) = q
Step-by-step explanation:
f(q) = q^2 -125
To find the roots set the equation equal to zero
0 = q^2 -125
Add 125 to each side
125 = q^2 -125+125
125 = q^2
Take the square root of each side
±sqrt(125) = sqrt(q^2)
±sqrt( 5*25) = q
±sqrt( 25)* sqrt(5) = q
±5* sqrt(5) = q
±5sqrt(5) = q
You do whatever you need to do to one side of the equation in order to have
only ' y ' left on that side, AND every time you do something to that side of
the equation, do exactly the same thing to the other side.
Here are three examples, out of the 9 answers you want handed to you:
<em>#16:</em> <u>3x + 5y = 7</u>
Subtract 3x from each side: 5y = -3x + 7
Divide each side by 5 : <em>y = -3/5 x + 7/5</em>
======================================
<em>#17: </em> <u>13 = 12x - 2y</u>
Add 2y to each side: 2y + 13 = 12x
Subtract 13 from each side: 2y = 12x - 13
Divide each side by 2 : <em> y = 6x - 13/2</em>
======================================
<em>#22:</em> <u>1/4 y + 3 = -5x</u>
Subtract 3 from each side: 1/4 y = -5x + 3
Multiply each side by 4 : <em>y = -20x + 12</em>
