Subtract the sum of the expressions (4x2 – 6x + 3) and (-5x2 + 5x + 2) from the sum of (7x2 – 8x + 2) and (6x2 – 3x + 8)

snow_lady [41]

Answer: [6x]

Step-by-step explanation:

(8 - 9x) = [1x]

(-10 + 7x) = [17x]

(14 - 16x) = [2x]

(12 - 24x) = [12x]

12x - 2x - 17x - 1x =

10x - 16x = [6x]

Jill, Meg, and Beth are sisters. Jill is 4 years younger than Meg. Enter an algebraic expression based on this situation. Let m

Murljashka [212]

Lets say

Jill=J

Meg=m

Beth=b

Jill is 4 years younger than meg so j+4=m

This is because if you add 4 to Jill's age, her age is going to be Megs age

Hope this helps and a brainliest would be appreciated

If 2x2 + y2 = 17 then evaluate the second derivative of y with respect to x when x = 2 and y = 3. Round your answer to 2 decimal

Vera_Pavlovna [14]

Answer:

y''=-1.26

Step-by-step explanation:

We are given that $2x^2+y^2=17$

We have evaluate the second order derivative of y w.r.t. x when x=2 and y=3.

Differentiate w.r.t x

Then , we get

$4x+2yy'=0$

$2x+yy'=0$

$yy'=-2x$

$y'=-\frac{2x}{y}$

Again differentiate w.r.t.x

Then , we get

$2+(y')^2+yy''=0$ $(u\cdot v)'=u'v+v'u)$

$2+(y')^2+yy''=0$

Using value of y'

$yy''=-2-(-\frac{2x}{y})^2$

$y''=-\frac{2+(-\frac{2x}{y})^2}{y}$

Substitute x=2 and y=3

Then, we get $y''=-\frac{2+(\frac{4}{3})^2}{3}$

$y''=-\frac{18+16}{9\times 3}=-\frac{34}{27}$

Hence,y''=-1.26
