Solve the proportion five point two over eight = y over six A. y = 4.22 B. y = 6.93 C. y = 2.86 D. y = 3.90

D.y = 3.9

Step-by-step explanation:

we can express the word problem five point two over eight = y over six mathematically;

our unknown is y, so we will keep rearranging the equation by using simple principles of algebra until we get y

cross multiply;

y×8 =5.2×6

y×8 =31.2

divide through by 8

y×8÷8 =31.2÷8

y=3.9

The correct answer is D

(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

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
