Consider Triangle ABC with A(-2,4), B(-2,-4), C(4,-4) and Triangle A'B'C'

Mathematics

Find the scale factor of the corresponding points. If the scale factor is the same for all points the triangles are similar.

A (-2, 4) x 2.5 = A’ (-5,10)

B(-2,4) x 2.5 = B’(-5,10)

C(4,-4) x 2.5 = C’(10,-10)

All three points have a scale factor of 2.5 so the two triangles are similar.

Find two numbers whose sum is 15 and the product is 36
ycow [4]
The two numbers are 3 and 12.

I got these numbers by factoring 36.

1 * 36    sum : 37
2 * 18    sum : 20
3 * 12    sum : 15

It is easier to find the factor of a number and solve for the sum. Than to find the addends of a number and solve for the product.

There are 9 factors of 36 while 14 addends of 15.

Which equation represents a line that has a slop of 3/4 and passes through the point (2,1)??
Veronika [31]

Answer:

  (B)  4y = 3x-2

Step-by-step explanation:

Divide by the coefficient of y to see the slope. It will be the resulting coefficient of x. Only choices B and D match requirements.

Check to see which equation is satisfied by the given point:

  B: 4(1) = 3(2) -2 . . . . true

  D: 4(1) = 3(2) +5 . . . .false

The appropriate equation is ...

  4y = 3x-2
