Answer:
The quotient is x² + 6x +3
Remainder = -1
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Polynomial equation
f(x) = x³+5x²−9x−7
By using synthetic division
<em> x = 2 </em> 1 5 -9 -7
<u> 0 1 12 6</u>
<u> 1 6 3 </u><em><u> -1 </u></em><u> </u>
The quotient is x² + 6x +3
Remainder = -1
Answer: y = 10 + x / 5
Step-by-step explanation:
Answer:
y = (-8/9)x + 0.77777
Step-by-step explanation:
We already know the slope, so the only thing left to find is the y-intercept.
To find the y-intercept, we can <u>plug in the slope and point to the slope-intercept form equation</u> (y = mx+b, where m=slope and b=y-int.)
y = m * x + b
(7) = (-8/9)*(-7) + b
<u>Now, just solve for b!</u>
(7) = (-8/9)*(-7) + b
7 = 56/9 + b
7 - (56/9) = b
b = 0.777777 (repeating decimal, usually signified by a little line above the 7)
so now we just <u>plug in the slope and y-intercept we found into y = mx + b.</u>
y = mx + b
y = (-8/9)x + 0.77777
Answer:
Variable 
represents the slope of the equation.
Step-by-step explanation:
Given that the administrative fees that company charge is $3.50.
Also, the Zhao has a bill of $63.25.
The equation used by Zhao is
We can compare the equation of a line in the slope-intercept form.
We can see the y-intercept is $3.50 that is a fixed cost. And the company charged $63.25 that is the dependent variable.
Also, variable that is the rate per kilowatt-hour (kWh) represents the slope of the equation.
