Answer:

1. y = 3x - 3

2. y = -2 1/2x + 10

10/-4 = -2 1/2 is the slope

3. undefined

4. y = x - 4

5. y = x - 5

6. 6x + 2y = 4 and -3y = 9x + 12

7. -3x + y = 7, y = 3x + 1, and y =3x

8. y = 2x + 5

9. y = 1/4x - 4

Fill in the blanks to explain how to solve 3/5 divided by 1/10.

MrMuchimi

You can use a common denominator and rewrite 3/5 divided by 1/10 as 6/10 divided by 1/10.
Than you can think, “How many ___s are in ___? (Sorry, i don’t know this part)
3/5 divided 1/10 is 6

Titiknya 10 dan 8<br> ∫x-8)( x-9) (x-10) dx

Sav [38]

$\displaystyle\int_8^{10}(x-8)(x-9)(x-10)\,\mathrm dx$

Consider the substitution,

$y=x-9\implies\begin{cases}y-1=x-10\\y+1=x-8\\\mathrm dy=\mathrm dx\end{cases}$

so that the integral is equivalent to

$\displaystyle\int_{-1}^1y(y+1)(y-1)\,\mathrm dy$

Notice that

$f(y)=y(y+1)(y-1)\implies f(-y)=-y(-y+1)(-y-1)=-y(y-1)(y+1)=-f(y)$

which means $f(y)$ is odd, so

$\implies\displaystyle\int_{-1}^1f(y)\,\mathrm dy=0$

Perhaps more work than necessary, but it does make it easier to see that the original integrand exhibits some symmetry about $x=9$ .
