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

Hoped I helped. Please give me brainliest :)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
