According to the substitution property of equality: if y = -5 and 7x + y = 11, then .  question 16 options: -5 + y = 11 7(-5) + y = 11 7x - 5 = 11 7x + 5 = 11

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Solve the triangle. a = 21°, c = 105°, c = 5

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities
