Solve the system of linear equations by graphing, round the solution to the nearest tenth.
y=-0.25x+4.7
y=4.9x-1.64
the approximate solution to the system is
is it y=-4 and y=4 or y=0 or no solution or all real numbers?

Solve |x| > -9 a) {x|x< -9 or x> 9} b) all reals c) no solution

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.

Write the equations in logarithmic form 10^3=1,000
