Answer:

5b(2 - 5b²)

Step-by-step explanation:

Simply take out GCFs to factor out the expression:

Step 1: Factor out GCF of 5

5(2b - 5b³)

Step 2: Factor out GCF of <em>b</em>

5b(2 - 5b²)

We can't factor the quadratic any further so that is our final answer.

Find the value of R so that the line that passes through each pair of points has the given slope: (8, -2 ), (r, -6), m=-4

kondor19780726 [428]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 8}}\quad ,&{{ -2}})\quad 
% (c,d)
&({{ r}}\quad ,&{{ -6}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-6-(-2)}{r-8}=-4
\\\\\\
\cfrac{-6+2}{r-8}=-4\implies -4=-4(r-8)\implies \cfrac{-4}{-4}=r-8\\\\\\ 1+8=r$

Answer:

Right option is (D).

ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Step-by-step explanation:

We have given,

Two triangles ΔABC and ΔDBE such as :

$\frac{BD}{BA} =\frac{BE}{BC}$

This relation will contribute to side side similarity.

Also,

∠B = ∠B , This will contribute as an angle similarity .

So combining above two relations,

$\frac{BD}{BA} =\frac{BE}{BC}$

and ∠B = ∠B

we can conclude that the triangle ΔABC and ΔDBE are similar triangles by side angle side similarity postulate.

Hence the right option is (C)
