4. mary is reviewing her algebra quiz. she has determined that one of her solutions is incorrect. which one is it? a. 2x + 5 (x-1) 9, x 2 b. p - 3(p-5) 10, p 2.5 c. 4 y +3 y 28, y 4 e. t - 2t - 3t 32, t 8

E. t - 2t - 3t =32, t=8

Step-by-step explanation:

A. 2x + 5 (x-1)= 9, X= 2 it's ok because

B. p - 3(p-5)= 10, p= 2.5 it's ok as well because

C. 4 y +3 y=28, y=4 also it's ok because

E. t - 2t - 3t =32, t=8 it's not ok because

a (-) is missing!

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
