D: -4x^2 has the narrowest graph
Exponential in form. y=AB^x
put data into calc should get
A = 1000 and B = 1.06
y=1000(1.06^x)
x=30 years, y=1000(1.06^30)=5743
A=1000 is the principal (initial deposit)
B=1.06 mean compound interest 6%
Lets try substitution5x+2y=21=5x=21-2y=x=(21-2y)/5
sub into second equation
-2(21-2y)/5+6y=-34(-42+4y)/5+6y=-34solve for yy=-64/17plug into equation and solve for x=(97/17)
Answer:
3:4
Step-by-step explanation:
18:24 —> 9:12–> 3:4
hope this helps :)
