4x + y = 15


A x = 2, y = 7

B. X = -13, y = 7

C x = -2/3, y = 12*2/3

D. x = 5, y = 1

Answers

Answer 1

Answer:

A

Step-by-step explanation:

6x+3y=33 <=> 2x+y=11<=>4x+2y=22 (1)

4x+y=15 (2)

(1)-(2) <=> y=7

Answer 2

Answer:

A x = 2, y = 7

Step-by-step explanation:

6(2)+3(7)= 33

what is the greatest number of relative maximum that a polynomial of degree 15 can have? Select the right answer among them 1. 14 2. 6 3. 9 4. 7 5. 4

Answers

Answer:

7

Step-by-step explanation:

The greatest number of relative maxima it can have is 14.

So, the correct answer would be option (1) 14.

Use the concept of a polynomial defined as:

An expression that consists of exponents, variables, and constants and that is combining many different mathematical procedures:

Addition, subtraction, and multiplication is referred to as polynomial.

Given that,

The degree of polynomial  = 15

The objective of this question determine the number of relative maxima it can have.

The number of relative maxima that a polynomial can have is equal to its degree minus 1.

In this case:

The polynomial is of degree = 15,

Hence,

The greatest number of relative maxima it can have is 15 - 1 = 14.

So, the correct answer would be option (1) 14.

41. - 0.8

42. - 2.375

43. - 0.625

44. - 0.833

45. - 3.667

46. - 0.5

Step-by-step explanation:

Before reading this, every integer represents the whole amount, like 1 is 1 of something, 2 is 2 of something, 3 is 3 of something, and 4 is 4 of something.

1/5 = 0.2

1 - 0.2 = 0.8

1/4 = 0.25

1/8 = 0.125

1 + 1 = 2

0.25 + 0.125 = 0.375

2 + 0.375 = 2.375

3/8 = 0.375

1 - 0.375 = 0.625

2/3 = 0.667

1/2 = 0.5

4.5 - 3.667 = 0.833

1/2 = 0.5

1/6 = 0.167

2 + 1 = 3

0.5 + 0.167 = 0.667

3 + 0.667 = 3.667

1/4 = 0.25

0.25 x 2 = 0.5
