Answer:

A) 4x+3y=14

B) 3x-2y=2

We multiply equation A) by (2/3)

A) (8/3) x +2y = 28/3 then we add this to equation B)

B) 3x-2y=2

5 (2/3) x = 11 (1/3)

x = 2

A) 4 * 2 + 3 y = 14

A) 3y = 6

y = 2

Lynomials and Linear Factors
kodGreya [7K]

Answer:

y = x³ + 2x² - 13x + 10

Step-by-step explanation:

Given

y = (x + 5)(x - 1)(x - 2) ← expand (x - 1)(x - 2)

  = (x + 5)(x² - 2x - x + 2)

  = (x + 5)(x² - 3x + 2)

Multiply each term in the second factor by each term in the first factor

= x(x² - 3x + 2) + 5(x² - 3x + 2) ← distribute both parenthesis

= x³ - 3x² + 2x + 5x² - 15x + 10 ← collect like terms

y = x³ + 2x² - 13x + 10

Omar is born weighing 8 pounds, and 3 ounces. The doctor says he should gain 5 ounces each week for 4 weeks. How much should omo
Monica [59]

Let's convert 8 pounds and 3 ounces, into all ounces.

So we know one pound = 16 ounces.

1 lb = 16 oz.

Now since Omar is 8 pounds + 3 ounces, we multiply 16 by 8, and add on the 3:

16 * 8 = 128

128 + 3 = 131

So Omar weights 131 ounces when he was born.

Now Omar has to gain 5 ounces each week, for 4 weeks. This means in total, he'll have to gain 5*4=20 ounces in 4 weeks.

Add them together:

131 + 20 = 151 oz OR 9 7/16 lb.
