Answer:
x = 12.48
y = 13.22
Step-by-step explanation
Im not sure if its correct
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = √156
b = 12.48
b= 12 ( If needed to round to the nearest whole number)
a^2 + 15^2 = 20^2
a^2 + 225 = 400
a^2 = √175
a = 13.22
a = 13 ( If needed to round to nearest whole number)
C because u have 3/7 which is a fraction
Substitute -1 for the variable x.
f(-1) = 2(-1) - 2
f(-1) = -2 - 2
f(-1) = -4
X=y+700
X is larger acct
Y is smaller acct
Larger acct equals amount in smaller account plus $700.
