Which statement summarizes Moira’s work? She correctly found the average rate of change. She expanded the expression for f(x + h) incorrectly. She simplified the difference quotient StartFraction f (x + h) minus f (x) Over h EndFraction incorrectly. She substituted incorrectly when evaluating the difference quotient.

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:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
