24x−6y=18 Step 1: Add 6y to both sides. 24x−6y+6y=18+6y24x=6y+18

Step 2: Divide both sides by 24.24x24=6y+1824x=14y+34

Sati [7]

Answer:

$x = \sqrt{11.4^2+2.6^2}\\\\$

Rounded to the nearest hundredths: 11.69.

Step-by-step explanation:

I would use the Pythagorean theorem for this problem.

The difference between the highest point and the lowest point of AD is 9.8-7.2 = 2.6, so that would be the height of the triangle. The length/base of the triangle would be 11.4.

Now, just solve using Pythagorean's theorem:

$x = \sqrt{11.4^2+2.6^2}\\\\$

Rounded to the nearest hundredths: 11.69.

I hope this helped you.

Determine f’(2) for f(x)=(x^2 -2x)(3x-1)

DanielleElmas [232]

<span>f(x)=(x^2 -2x)(3x-1) is a product and is most easily differentiated using the product rule:

f '(x) = (x^2 - 2x)(3) + (3x-1)(2x-2)

Now subst. 2 for x in this equation. We get:

f '(2) = (2^2 - 2(2))*3 + (3(2)-1)(2(2) -2), or
=3(4-4) + (6-1)(2) so f '(2) = 10 (answer)</span>
