First, find the slope of the line thru these 2 pts:

5-4
m = --------- = -1/2
2 -4

Use the slope-intercept formula y = mx + b:

5 = (-1/2)(2) + b. Then the y-intercept is 5 + 1, or 6: y = (-1/2)x + 6

Multiplying this entire result (3 terms) by 2 results in 2y = -x + 12, or

x + 2y = 12 (answer)

PolarNik [594]

Area of rectangle = lb = 47 m^2

Dilation by a factor of 7 results in 1/7 l x 1/7 b = 1/49 lb = 1/49 (47) = 47/49 = 0.9592

A triangle has two sides that are perpendicular. Could the triangle be isosceles, equilateral, or scalene? Explain.

garri49 [273]

Answer:

Isosceles and scalene

Step-by-step explanation:

Isosceles triangle means two angles must be equal and one angle 90 degrees. It is called isosceles right triangle.

We know that one angle is 90 degrees

90 -45-45 degrees

This could be scalene triangle, the other two angles must add upto 90 degrees

It could be 30 and 60 or any other combination.

90-60-30

The answer is Isosceles and scalene

Hope this will helpful.

Thank you.
