Answer:
y = 3x + 2 is the equation
Step-by-step explanation:
y intercept is where x is 0 that means y intercept is 2.
slope is change in y over change in x which is 3
Bianca's bank offers a savings account with a 2.1% APR,
compounded monthly. The the actual annual percentage yield on this account can
be calculated using i = (1+ r/m)^m, where i is the actual APR, r is the nominal
interest rate and m the compounding period in a year. APR is equal to 2.12%
Ok so first u would add 3+1 which gives u 4 and then add 1/4 which should give u 4 1/4
5x + y = 15
y = -5x + 15
Substituting y= -5x+15 from first equation into second equation:
3x + 2y = 16
3x + 2·(-5x + 15) = 16
3x - 10x + 30 = 16
-7x + 30 = 16
7x = 30 - 16 = 14
x = 2
Substituting x=2 into the first equation:
5x + y = 15
5(2) + y = 15
10 + y = 15
y = 15 - 10
y = 5
So your final answers are x=2 and y=5.
