on patrick's test he got 14 multiple choice questions and 6 true or false questions correct. patrick also got 1 multiple choice

solniwko [45]

So first add the multiple choice together to get 15 and the true/false together to get 10. Then add those together to get 25. Since there was 15 multiple choice, divide 15 by 25 to get 3/5. This is .8 in decimal form and to convert it to a percent multiply it by 100 to get 80%. Hope this helps!

Graph the function g(x) = 1/3 - 4/3x

True [87]

Solutions

g(x) = $\frac{1}{3}$ - $\frac{4}{3}$ x

 g(x) = - $\frac{4}{3}$ x + $\frac{1}{3}$

x = -5

= g(x) = - $\frac{4}{3}$ × (-5) + $\frac{1}{3}$

= $\frac{20}{3}$ + $\frac{1}{3}$

= $\frac{21}{3}$

= 7

(-5,7)

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

x = 7

 = g(x) = - $\frac{4}{3}$ × (7) + $\frac{1}{3}$

= $\frac{-28}{3}$ + $\frac{1}{3}$

= $\frac{-27}{3}$ = -9

(-7,9)

x = (-7,9) y = (-5,7)
