Answer: r=6
Step-by-step explanation:
Because if 42 equals 7 times r you just have to divide 42 by 7.
For a system of two variables and two equations, each equation will be a linear graph, and where the lines intersect is the solution as an ordered pair (x,y). If the lines don’t intersect (they’re parallel) so there is no unique solution.
(f-g) (x) means to subtract g(x) from f(x)
F(x) = 2x^2 +3
g(x) = x^2
This becomes:
2x^2 + 3 - x^2 = x^2 +3
Rainfall in July = 2.79 inches.
July has 31 days.
2.79 : 31 = x : 1 Set up the proportion
2.79 / 31 = x/1 Cross multiply and switch.
2.79*1 / 31 = x Do the division
0.09 inches = x Answer
The equation for interest is
'Initial amount (interest rate in decimal form) ^ times compounded EX: years'
your equation would be
400(1.04)^10
which equals 592.097713 (not rounded)
