<span>ralph = r
sara = s
ralph is TODAY, 3 times older, so if sara is "s" old, ralph is 3s
r = 3s
in 6 years, ralph will be 2 times as old as sara THEN,
in 6 years ralph will be TODAY's age plus 6, so r + 6
so if sara is "s" old, r+ 6 = 2s
r + 6 = 2s</span>
The equation of any circle is
(x - a)^2 + (y - b)^2 = radius^2 where our center is (a, b)
Therefore, our equation is as follows.
(x + 2)^2 + (y - 3)^2 = 16
The triangle is an Obtuse triangle
Answer:
3rd option
Step-by-step explanation:
A direct variation is expressed in this form:
y = kx
1. y - 4x = 8
y = 4x + 8 is not a direct variation
2. y + 2 = 7x
y = 7x - 2 is not a direct variation
3. y - 3x = 0
y = 3x is a direct variation
4. y = 5x - 2
y = 5x - 2 is not direct variation
Answer:
Length: 16
Width: 8
Step-by-step explanation:
