So,
We are trying to figure out when Grandpa Lopez's age was twice that of Dad.
Let x represent the number of years before/after when G. Lopez's age was twice that of Dad.
66 + x = 2(37 + x)
Distribute.
66 + x = 74 + 2x
Subtract x from both sides.
66 = 74 + x
Subtract 74 from both sides.
-8 = x
So 8 years ago, G. Lopez was twice as old as Dad. Let's check that.
66 - 8 = 58
37 = 8 = 29
29 * 2 = 58
58 = 58
It checks.
Answer:
The answer to your question is y = 4/6x - 4
Step-by-step explanation:
Data
m = 4/6
P (0, -4)
slope-intercept form = ? y = mx + b where m is the slope and
b is the y-intercept
Formula
y - y1 = m(x - x1)
Substitution
y - (-4) = 4/6(x - 0)
Simplification
y + 4 = 4/6x
Result
y = 4/6x - 4
slope = 4/6 y-intercept = -4

I hope this helps!
Step-by-step explanation:
3y(5x+3)=15yx+9y
2y(2x+3)=4yx+6y
4y(x+2)=4yx+8y
3y(7x+2)=21yx+6y
Answer: rational
Step-by-step explanation:
-6 can be written as such an infinite number of ways (just as any rational can be). For example, -6/1, 6/-1, 12/-2, -666/111 and so indeed -6 is rational.
