Answer:
y=-13
Step-by-step explanation:
Plugging in -7:
y= (-7)2 + 1
-7 * 2 = -14
So:
y= -14 + 1
-14+1=-13
M is 15x and b is 60. hope I helped
Answer:
the ratio is the same
Step-by-step explanation:
Girls
12 out of 30
12/30
Divide top and bottom by 6
2/5
Boys
16 out of 40
16/40
Divide top and bottom by 8
2/5
For this case, what you should know is that the equations that represent an inverse variation are those that could not form a straight line, for example.
We have then:
Equation 1:
pv = 13
Rewriting:
p = 13 / v
P and v are represent an inverse variation.
Equation 2:
z = (2 / x)
z and x are represent an inverse variation.
Answer:
equations represented inverse variation are:
pv = 13
z = (2 / x)

Answer:
C) 12y 8m
Step-by-step explanation:
The amount of principal P at compound monthly at interest rate r per year is given by ...
A = P(1 +r/12)^(12t) . . . . after t years
Here, we want to find t, so ...
A/P = (1 +r/12)^(12t)
log(A/P) = (12t)·log(1 +r/12)
t = log(A/P)/(12·log(1 +r/12))
Filling in the given values, we find t to be ...
t = log(8000/4000)/(12·log(1 +0.055/12)) ≈ 12.6315 ≈ 12 years 7.6 months
It will take about 12 years 8 months to double the money.
