The ideal temperature for proofing yeast for baking is 107.5°F. However, yeast will proof within a variation of 2.5°F. Write an absolute value inequality to model this situation, and then use the inequality to complete the statement.
Yeast will proof in temperatures that are at least
°F and at most
°F degrees.

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?

Identify which functions are linear or non-linear. a. f(x) = x2 + 1 b. f(x) = 2x + 5 c. f(x) = x 2 + 3 d. f(x) = 3 x + 7 e. f(x) = 4x + 10 2 - 5

Can someone me out here number 4 plz
