Mathematics
1 answer:
WITCHER [35]3 years ago
3 0

Answer:

c.) x = 3

Step-by-step explanation:

2x - 3y = 9

x = 4 + y

Substitute the second equation into the first equation

2(4+y) - 3y = 9

Distribute

8+2y -3y =9

8-y = 9

Subtract 8 from each side

8-y-8 =9-8

-y = 1

Multiply by -1

y =-1

Now solve for x

x = 4-1

x =3

Which of the following shows the factors of 5x2 + 17x + 6? A. (5x + 1)(x + 6) B. (5x + 2)(x + 3) C. (5x + 3)(x + 2) D. (5x + 6)(
zysi [14]

Answer:

B. (x+3)(5x+2)

Step-by-step explanation:

The given quadratic trinomial is;

5x^2+17x+6

Comparing this to ax^2+bx+c, we have a=5,b=17,c=6.

ac=5\times6=30

Two factors of 30 that add up to 17 is 15  and 2.

We split the middle term to obtain;

5x^2+15x+2x+6

We factor by grouping;

5x(x+3)+2(x+3)

Factor further

(x+3)(5x+2)

The correct answer is B.

The researchers have also determined that the current rate of the rise in water level is twice the 1880 to 2009 rate. assuming t
Elden [556K]

Answer:

  1. x ≥ 2009
  2. 3.2x -6222.8
  3. 257.2 mm
  4. year 2100

Step-by-step explanation:

1. The problem statement tells you the function applies for year values (x) 2009 and later. The domain is real numbers greater than or equal to 2009.

__

2. We can use the distributive property to eliminate parentheses:

  3.2(x -2009) +206 = 3.2x -6428.8 +206

  = 3.2x -6222.8

__

3. Put 2025 in the equation and do the arithmetic

  g(2025) = 3.2·2025 -6222.8 = 257.2 . . . . mm

__

4. Put this value of level rise in the equation and solve for x.

  g(x) = 3.2x -6222.8

  500 = 3.2x -6222.8 . . put 500 mm where g(x) is in the equation

  6722.8 = 3.2x . . . . . . . add 6222.8

  x = 6722.8/3.2 = 2100.875

The water rise will be equal to about half a meter late in the year 2100.
