(c) jessica is training for the 400 meter relay race. she has trained three times this week and took 46, 52, and 54 seconds on her 400 meter races. what is the maximum amount of time she can spend on her fourth race to average at most 51 seconds? show your work and justify your steps.

56 seconds or less

Step-by-step explanation:

3(46 + 52 + 54) 400 - x

Combine

3(152) 400 - x

Simplify

456 400 - x

Subtract 456 from both sides

0 -56 - x

Add x to both sides

x 56 seconds

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
