The slope is found using the formula;
=\frac{change in y}{change in x}
=\frac{4--1}{3--2}
=\frac{5}{5}
=1

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{4 - (-1)}{3 - (-2)} = \frac{4 + 1}{3 + 2} = \frac{5}{5} = 1

y - y₁ = m(x - x₁)
 y - 4 = 1(x - 3)
 y - 4 = 1(x) - 1(3)
 y - 4 = x - 3
   + 4      + 4
      y = x + 1

\bf \cfrac{(a-3)\left( \frac{a}{3}+1 \right)}{\frac{1}{3}}\implies 3\left[ (a-3)\left( \frac{a}{3}+1 \right) \right] \\\\\\ 3\left[\frac{a^2}{3}+a-a-3  \right]\implies 3\left[\frac{a^2}{3}-3  \right]\implies a^2-9

when you have polynomials multiplication, say (x+y) (a+b+c), you can always just multiply x(a+b+c) + y(a+b+c), namely each term by all others and sum them up, like above.

Can someone help me with this
jarptica [38.1K]

The answer is:

x=-8

Because:

If you pick a number(-8) to fill in the equation written below

5x+20+5x=5x-20

After applying the -8 to x you get

-40+20-40=-40-20

When you simply the both sides you get

-60=-60

And that’s right -60 is equal to -60!
