A park ranger recorded this random sample of height data for the two types of trees shown.
Which statement is best supported by this data?
A. Redwoods grow more slowly than Douglas firs.
B. Redwoods are 100 times taller than Douglas firs.
C. Redwoods grow to be about 60 feet taller than Douglas firs on
average.
D. Redwoods are shorter than Douglas firs since the range for
Redwoods is smaller than the range for Douglas firs.

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
