3 / 15 = 1 / 5
5 / 20 = 1 / 4

so no, they are not. we know this because when you turn them into proportions and simplify them, the two rates are not equal

Find the coordinates of the point three tenths<br><br> of the way from A(-4, -8) to B(11, 7)

Leviafan [203]

let's first off take a peek at those values.

let's say the point with those coordinates is point C, so C is 3/10 of the way from A to B.

meaning, we take the segment AB and cut it in 10 equal pieces, AC takes 3 pieces, and CB takes 7 pieces, namely AC and CB are at a 3:7 ratio.

$\bf ~~~~~~~~~~~~\textit{internal division of a line segment}
\\\\\\
A(-4,-8)\qquad B(11,7)\qquad
\qquad \stackrel{\textit{ratio from A to B}}{3:7}
\\\\\\
\cfrac{A\underline{C}}{\underline{C} B} = \cfrac{3}{7}\implies \cfrac{A}{B} = \cfrac{3}{7}\implies 7A=3B\implies 7(-4,-8)=3(11,7)\\\\[-0.35em]
~\dotfill\\\\
C=\left(\frac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \frac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\[-0.35em]
~\dotfill$

$\bf C=\left(\cfrac{(7\cdot -4)+(3\cdot 11)}{3+7}\quad ,\quad \cfrac{(7\cdot -8)+(3\cdot 7)}{3+7}\right)
\\\\\\
C=\left( \cfrac{-28+33}{10}~~,~~\cfrac{-56+21}{10} \right)\implies C=\left( \cfrac{5}{10}~~,~~\cfrac{-35}{10} \right)
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
~\hfill C=\left( \frac{1}{2}~,~-\frac{7}{2} \right)~\hfill$

What is another point on the line?

Kamila [148]

Answer:

B. (0,9)

Step-by-step explanation:

Start the point on (4,3), and becasue the slope is -3/2 you do rise over run. so you could go up 3 and left 2 or down 3 and right 2. i went up 3 and left to twice from point (4,3) and arrived at point (0,9). so the answer is B. (0,9)

Helppppppppppppppppppp pls

Marizza181 [45]

Step-by-step explanation:

0.2x = 20

The step that should be done is to multiply both sides by 5:

5(0.2x) = 5(20)

x = 100.
