Answer:
<h3>The average weekly change in value of Jade's stock in dollars is -1.3225</h3>
Step-by-step explanation:
Given that Jade invested in the stock market.
The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75 and +5.98.
<h3>To find the average weekly change in value of her stock in dollars :</h3>
The average weekly change in value of Jade's stock is given by 
Therefore Average=-1.3225
<h3>Therefore the average weekly change in value of Jade's stock in dollars is -1.3225</h3>
To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
7x - 21 = 4x + 20
Transpose all the terms with x and the constant on either sides of the equation,
7x - 4x = 20 + 21
3x = 41 ; x = 41 / 3
Thus, the answer is x = 41/3 which is fourth among the choices.
Answer:
x^2 -2x -35 = 0
Step-by-step explanation:
Lets's solve backwards
x = -5
Add 5 to both sides
x + 5 = 5 - 5
x + 5 = 0
and
x = 7
Subtract 7 from both sides
x - 7 = 7 - 7
x - 7 = 0
Finding the product of both linear functions
(x + 5)(x - 7) =0
x^2 -7x + 5x -35 =0
x^2 -2x -35 = 0
Answer:
add the whole numbers. -9+10=1
1 2-3/7
remove one digit from the whole number:. 1-1=0
add the denominator to 2=7+2=9
:. 9-3/7=6/7
answer=6/7
