Differentiate. Y=5x^2 +6x

Mathematics

The answer to this question is y' = 10x^2 + 6. You have to use the power rule to bring the exponent down as a coefficient and then reduce the exponent by 1. Do it for all the terms using the sum rule for derivatives (derivative of a sum of the sum of its derivatives).

You triple your account balance by making a deposit. Then you withdraw $28.50 from your bank account. Now your account is overdr
Crazy boy [7]

Answer:

Your original account balance before you made the deposit is $6

Step-by-step explanation:

Let x = your original account balance.

You triple your account balance by making a deposit. This means

New account balance = 3 × x = 3x

Then you withdraw $28.50 from your bank account. This means that you have $(3x - 28.5) left.

Now your account is overdrawn by $10.50. This means you have withdrawn beyond what you have in your account. Your new account balance is -$10.5. Therefore,

3x - 28.5 = - 10.5

3x = -10.5 + 28.5 = 18

x = 18/3 = 6

Your original account balance before you made the deposit is $6

Find the slope of the line graphed below
Korolek [52]

Answer:

Slope = 1

Step-by-step explanation:

(x1, y1) = (-5, -3)

(x2, y2) = (-1, 1)

(y2 - y1) / (x2 - x1) = (1 - -3) / (-1 - -5) = 4 / 4 = 1

Slope = 1

How many more calories do you burn per minute downhill skiing than hiking
FrozenT [24]

Answer: 2 more calories skiing

Step-by-step explanation:

First find the slope of each line.

Slope of Skiing:

= (Y₂ - Y₁) / (X₂ - X₁)

= (400 - 240) / (50 - 30)

= 8

= 8 calories per minute

Slope of Hiking

= (360 - 120) / (60 - 20)

= 6

= 6 calories per minute

Difference:

= 8 - 6

= 2 more calories skiing
