Can somebody me? write the phrase as an expression. then evaluate when x = 2 and y = 10. #1 twelve more than the product of 5 and a number x. #2 15 decreased by the product of a number x and 4. #3 you eat 5 slices of bread. your friend eats 2 slices fewer than you eat. write an expression that describes the number of slices your friend eats. #4 your uncle is 2 years older than 3 times your age. a. you are x years old. write an expression that describes your uncle's age. b. you are 12 years old. how old is your uncle.

Step-by-step explanation:

1) Twelve more than the product of 5 and a number x. This is expressed as

y = 5x + 12

when x = 2,

y = 5×2 +12 = 22

and when y = 10

10 = 5x + 12

5x = - 2

x = -2/5

2) 15 decreased by the product of a number x and 4. This is expressed as

y = 15 - 4x

When x = 2

y = 15 - 4×2 = 7

When y = 10

10 = 15 - 4x

4x = 15 - 10 = 5

x = 5/4

3) You eat 5 slices of bread. Your friend eats 2 slices fewer than you eat.

Let y represent the number of slices that your friend ate. The expression will be

y = 5 - 3 = 2

y = 2

4) Your uncle is 2 years older than 3 times your age. A. You are x years old. Let your uncle be y years old. Therefore,

y = 3x + 2

If you are 12 years old, your uncle well be

3×12 + 2 = 38 years old

(2 x^3 + 7 x^2 + 5 x + 2)/(x (x + 2))

step-by-step explanation:

simplify the following:

x/x^2 + 3 x + 2 - (x (x + 1))/(x + 2)

combine powers. x/x^2 = x^(1 - 2):

x^(1 - 2) + 3 x + 2 - (x (x + 1))/(x + 2)

1 - 2 = -1:

x^(-1) + 3 x + 2 - (x (x + 1))/(x + 2)

put each term in 1/x + 3 x + 2 - (x (x + 1))/(x + 2) over the common denominator x (x + 2): 1/x + 3 x + 2 - (x (x + 1))/(x + 2) = (x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2)):

(x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2))

(x + 2)/(x (x + 2)) + (3 x^2 (x + 2))/(x (x + 2)) + (2 x (x + 2))/(x (x + 2)) - (x^2 (x + 1))/(x (x + 2)) = ((x + 2) + 3 x^2 (x + 2) + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2)):

(2 + x + 3 x^2 (x + 2) + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2))

3 x^2 (x + 2) = 3 x^3 + 6 x^2:

(2 + x + 3 x^3 + 6 x^2 + 2 x (x + 2) - x^2 (x + 1))/(x (x + 2))

2 x (x + 2) = 2 x^2 + 4 x:

(2 + x + 6 x^2 + 3 x^3 + 2 x^2 + 4 x - x^2 (x + 1))/(x (x + 2))

-x^2 (x + 1) = -x^2 - x^3:

(-x^2 - x^3 + 3 x^3 + 6 x^2 + 2 x^2 + 4 x + x + 2)/(x (x + 2))

grouping like terms, 3 x^3 - x^3 + 6 x^2 + 2 x^2 - x^2 + 4 x + x + 2 = (3 x^3 - x^3) + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2:

((3 x^3 - x^3) + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2)/(x (x + 2))

3 x^3 - x^3 = 2 x^3:

(2 x^3 + (6 x^2 + 2 x^2 - x^2) + (x + 4 x) + 2)/(x (x + 2))

6 x^2 + 2 x^2 - x^2 = 7 x^2:

(2 x^3 + 7 x^2 + (x + 4 x) + 2)/(x (x + 2))

x + 4 x = 5 x:

answer:   (2 x^3 + 7 x^2 + 5 x + 2)/(x (x + 2))

i dont know if you cant find a way its best to actually add all of them start from 105 tho
