NNADVOKAT [17]2 years ago
3 0

Answer:

4x + b

Step-by-step explanation:

The derivative of a polynomial is the sum of the derivative of it's terms. The derivative of a constant term is 0. The derivative of the ( ax to the n) is ( nax to the n-1 )

2 x 2x(²minus¹ )+ bx(¹minus¹)

multiple 2x2

4x²–¹ + bx¹–¹

subtract 1 from 2

4x¹ + bx¹–¹

subtract 1 from 1

4x¹ + bx⁰

for any term t, t¹ = t

4x + bx⁰

for any term t except 0

t⁰ = 1

4x + b x 1

for any term t, t x 1 = t

and 1t = t

4x + b

HELP HELP HELP HELP <br><br> What is the equation of the trend line in the scatter plot ?
Firlakuza [10]

Answer:

y = (4/7)x + 3

Step-by-step explanation:

rise = 7 - 3 = 4

run = 7 - 0 = 7

slope = rise/run = 4/7

y-intercept = 3

---------------------

Slope intercept form is

y = mx + b

m is the slope = 4/7

b is the y-intercept  = 3

the equation is

y = (4/7)x + 3

Please solve this <br>Solve by completing the square. 4x2+8x−3=0
Greeley [361]

Step-by-step explanation:

4x2+8x−3=0

For this equation: a=4, b=8, c=-3

4x2+8x+−3=0

Step 1: Use quadratic formula with a=4, b=8, c=-3.

x=

−b±√b2−4ac

2a

x= −(8)±√(8)2−4(4)(−3)

2(4)

x= −8±√112

8  x=−1+

1 2 √7 or x=−1+

−1 2 √7

Answer:  x=−1+

1 2√7 or x=−1+

−1 2 √7

If you make $450 a month but 15% is held out of each paycheck for Social Security and taxes how much do bring home?
aksik [14]

To solve this question make an equation

450 x 0.15 = X

0.15 = the percentage taken out of the paycheck

67.5 = Social Security Taxes

450 - 67.5

= $382.5

Or the easier way if you want it straight away

450 x 0.85 = $382.5

0.85 = percentage taken home

The equation of a line L1 is y=5x+1
Korolek [52]

Answer:

Lines are considered parallel if their slopes are the same.  In Line 1, the slope is 5 and in Line 2, when we solve for 'y', we also get a slope of 5, which means the two lines are parallel.  

Step-by-step explanation:

In order to find slope, it is easiest to put the equation in slope-intercept form, or y=mx + b, where m = slope and b=y-intercept.  In L1, y=5x +1 indicates a slope of 5.  In L2, the equation is not in slope-intercept form, so we must solve for 'y' using inverse operations:  2y - 10x +3 = 0, start by subtracting 3 from both sides of the equal sign:  2y - 10x +3 -3 = 0 - 3 gives us 2y - 10x = -3.  Then add '10x' to both sides:  2y - 10x + 10x = -3 + 10x gives us 2y = 10x - 3.  Lastly, divide all terms by 2:  2y/2 = (10/2)x - 3/2 or y = 5x - 1.5.  Now that L2 is in slope-intercept form, we can see that m=5 as in L1, so since they have the same slope, they are parallel lines.
