Answer:
Step-by-step explanation:
Let the first number = x
Let the second number = y
x + y = 24
<u>7x - y = 16 </u> Add these two equations
8x = 40 Divide by 8
8x/8 = 40/8
x = 5
The smaller number will be 5
================
5 + y = 24
y = 19
==================
Proof
7*5 - 19 = 16
35 - 19 = 16
The center is the midpoint of these two points, so is ((-4+2)/2, (-2+6)/2) = (-1, 2). The radius is the distance from the center to either of these points. Its square is 3^2 +4^2 = 25.
The equation of the circle is
.. (x +1)^2 +(y -2)^2 = 25
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that
is the same as a*d = b*c
is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4
