Answer:

hello :

3x3 – 11x2 – 26x + 30 divided by x – 5 is :3x2 + 4x – 6

because :

(x-5)(3x²+4x-6)=3x^3+4x²-6x-15x²-20x+30 =3x3 – 11x2 – 26x + 30

Y=3/4X-5 POINT SLOPE FORM
lesantik [10]

Answer:

y + 5 = (3/4)x

Step-by-step explanation:

You want to rewrite Y=3/4X-5 in POINT SLOPE FORM?

Point-slope form looks like y-k = m(x-h), where (h,k) is a point on the line and m is the slope of the line.

Starting with Y=3/4X- 5, identify the slope and one point on the line.  The slope is (3/4) (please surround fractions like this inside parentheses) and the y-intercept is (0, -5).  We will let h=0 and k= -5.

Thus, we have a point on the line and we have the slope of the line.  

We can now write the point-slope form:

y - (-5) = (3/4)(x - 0), or y + 5 = (3/4)x.  This is the desired equation in point-slope form.

Point A is located at (5, 10) and point B is located at (20, 25).
Alla [95]
Let's say the point is C, so C partitions AB into two pieces, where AC is at a ratio of 3 and CB is at  a ratio of 7, thus 3:7,

\bf \left. \qquad  \right.\textit{internal division of a line segment}
\\\\\\
A(5,10)\qquad B(20,25)\qquad
\qquad 3:7
\\\\\\
\cfrac{AC}{CB} = \cfrac{3}{7}\implies \cfrac{A}{B} = \cfrac{3}{7}\implies 7A=3B\implies 7(5,10)=3(20,25)\\\\
-------------------------------\\\\
{ C=\left(\cfrac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \cfrac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)}\\\
-------------------------------

\bf C=\left(\cfrac{(7\cdot 5)+(3\cdot 20)}{3+7}\quad ,\quad \cfrac{(7\cdot 10)+(3\cdot 25)}{3+7}\right)
\\\\\\
C=\left( \cfrac{35+60}{10}~~,~~\cfrac{70+75}{10} \right)\implies C=\left(\cfrac{95}{10}~~,~~\cfrac{145}{10}  \right)
\\\\\\
C=\left( \cfrac{19}{2}~~,~~\cfrac{29}{2} \right)\implies C=\left( 9\frac{1}{2}~~,~~14\frac{1}{2}  \right)

Write an equation in slope-intercept form of the line that passes through (6.-1) and (3.-7).
Morgarella [4.7K]

Answer:

y=2x-13

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-7-(-1))/(3-6)

m=(-7+1)/-3

m=-6/-3

m=2

y-y1=m(x-x1)

y-(-1)=2(x-6)

y+1=2(x-6)

y=2x-12-1

y=2x-13
