Find the point B on AC such that the ratio of AB to BC is 2:3

Virty [35]

Answer:

B(4, - 3 )

Step-by-step explanation:

We have A(2, - 7) and C(7, 3 )

Using the section formula to calculate the coordinates of B

$x_{B}$ = $\frac{3(2)+2(7)}{2+3}$ = $\frac{6+14}{5}$ = $\frac{20}{5}$ = 4

$y_{B}$ = $\frac{3(-7)+2(3)}{2+3}$ = $\frac{-21+6}{5}$ = $\frac{-15}{5}$ = - 3

Hence B(4, - 3 )

I need help with this

yawa3891 [41]

Answer:

Step-by-step explanation:

In the graph given, we can expect the x axis to be horizontal and the y axis to be vertical. This means that the arm span represents y and the height represents x.

Therefore, if a girl on her team is 63 inches tall, we can say that y=x+2, and since height is x, y = 63 + 2 = 65

Find the equation of the line that passes through the given points. (1, 4.5) and (3, 6)

Zanzabum

Answer:

y=0.75x+3.75

Step-by-step explanation:

The slope is

$\frac{6 - 4.5}{3 - 1} = \frac{3}{4}$

Substituting into point-slope form,

y - 6 = 0.75(x - 3)

y - 6 = 0.75x - 2.25

y = 0.75x + 3.75
