When Anna buys 3 pencils, she spends a $1.50. Each pencil cost the same

0 pencils = 0 dollars

1 pencil = 0.5 dollars

5 pencils = 2.5 dollars

6 pencils = 3 dollars

The graph is in the word attachment

Step-by-step explanation:

If 3 pencils cost 1.5 dollars, then:

=> 0 pencils = 0 dollars

=> 1 pencil = 0.5 dollars

=> 5 pencils = 0.5 times 5

= 5 pencils = 2.5 dollars

=> 6 pencils = 2.5 + 0.5

=> 6 pencils = 3 dollars

I have created a word attachment of the graph. Check it out!

Hoped I helped. Please give me brainliest :)

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer: -0.5 would be the most likley outcome
