Answer this please......

Brrunno [24]

Answer:

1). Option A

2). Option B

Step-by-step explanation:

Question 1

Rule for the dilation of a point by a scale factor 'k' is given by the rule,

(x, y) → (kx, ky)

By this rule image of point A when dilated by the scale factor = 1.25,

A(-12, -8) → A'[(-12 × 1.25), (-8 × 1.25)]

→ A'(-15, -10)

Option A will be the answer.

Question 2

Scale factor = $\frac{\text{Dimension or one side of the image}}{\text{Dimension or one side of the preimage}}$

From the figure attached,

Scale factor = $\frac{F'E'}{FE}$

= $\frac{4}{14}$

= $\frac{2}{7}$

Therefore, rule for the dilation of ABC to form image triangle A'B'C' will be,

(x, y) → $(\frac{2}{7}x, \frac{2}{7}y)$

Option B will be the answer.

Find the equation of the line that passes through the point (7,5) and is perpendicular to the line 2x - 3y=6

balu736 [363]

$(7,5);\ \ \ \ 2x - 3y=6 \ \ / subtract \ 2x \ from \ each \ side \\ \\-3y = -2x + 6\ \ / divide \ each \term \ by \ (-3) \\ \\ y = \frac{2} {3}x -2\\ \\ The \ slope \ is :m _{1} = \frac{ 2}{3} \\ \\ If \ m_{1} \ and \ m _{2} \ are \ the \ gradients \ of \ two \ perpendicular \\ \\ lines \ we \ have \\\\\ m _{1}*m _{2} = -1$

$\frac{2}{3}\cdot m_{2}=-1\ \ / \cdot (\frac{3}{2})\\\\m_{2}=-\frac{3}{2}\\\\Now \ your \ equation \ of \ line \ passing \ through \ (7,5) would \ be: \\ \\ y=m_{2}x+b \\ \\5=-\frac{3}{2}\cdot 7 + b \\ \\ 5= -\frac{21}{2}+b\\ \\b=5+\frac{21}{2} \\ \\b= \frac{10}{2}+\frac{21}{2}\\ \\b= \frac{31}{2}\\\\b=15.5 \\ \\ y = -\frac{3}{2}x +15.5$
