<span>5x^2-17x+6
</span>=(x - 3)(5x - 2)

x-3 = 0 then x =3
5x - 2 =0
5x = 2
x =2/5

answer: x =3 and x =2/5

Y=6 when x=18, find y when x=-12

so 6/18 = y/-12
cross multiplication
(6)(-12) = (18)(y)
-72 = 18y
divide both sides by 18
-4 = y

Hope this helps

Solve the given differential equation by using an appropriate substitution. the de is homogeneous. (y2 yx) dx − x2 dy = 0

Schach [20]

The solution for the given differential equation is lnlxl = $\frac{-x}{y} +C$

Given,

$(y^{2} +y^{x} )dx - x^{2} dy =0$

Here,

x = vy, dx = vdy + ydv

y = ux, dy = udx + xdu

Then,

$((ux)^{2} +(ux)x)dx-x^{2} (udx+xdu)=0\\=u^{2} x^{2} dx+ux^{2} dx-x^{2} udx-x^{3} du=0\\=u^{2} x^{2} dx=x^{3} du\\=\frac{x^{2} }{x^{3} } dx=\frac{1}{u^{2} } du$

Now,

$\int\limits^a_b {\frac{1}{x} } \, dx =\int\limits^a_b {u^{-2} } \, du$

l $n$ l $x$ l $=\frac{u^{-1} }{(-1)} +C$

l $n$ l $x$ l $=\frac{-1}{u} +C$

y = ux

u = $\frac{y}{x}$

That is l $n$ l $x$ l $=\frac{-x}{y} +C$

Asking again... Please help! 1/20, will give brainliest. I do not tolerate spam answers!

Answer:

(x + 7)(x + 5)

Step-by-step explanation:

Given

x² + 12x + 35

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5 , since

7 × 5 = + 35 and sum = 7 + 5 = + 12, then

x² + 12x + 35 = (x + 7)(x + 5) ← in factored form

Whitney has £265 Nancy has £180 They each spend the same amount of money. Whitney has twice as much money as Nancy left now. How

Furkat [3]

Answer:

£95

Step-by-step explanation:

Given that:

Whitney's initial amount = £265

Nancy's initial amount = £180

Let amount each spent = x (amount is the same)

After spending Whitney has twice as much money as Nancy.

Amount spent by each?

(Whitney's initial amount - x) = 2(Nancy's initial amount - x)

265 - x = 2(180 - x)

265 - x = 360 - 2x

-x + 2x = 360 - 265

x = £95

Hence, they both spent £95
