2(6 + 2y) = 28

(6 x 2 + 2y x 2) = 28

(12 + 4y) = 28

12 + 4y = 28

 12 + -12 + 4y = 28 + -12

 12 + -12 = 0

0 + 4y = 28 + -12

4y = 28 + -12

 28 + -12 = 16

4y = 16

16\4

 y = 4

Combine like terms to simplify the following expressions <br><br> -5a - 4a + b
Sauron [17]

Answer:

-9a + b

Step-by-step explanation:

For this problem, let us factor out the variable a from the terms containing the variable, and apply addition and the distributive property to simplify the terms.

-5a - 4a + b

= a ( -5 + -4 ) + b

= a ( -9 ) + b

= -9a + b

Hence, the simplified expression for -5a - 4a + b is -9a + b.

Cheers.

Anit [1.1K]

Answer:

  • 3^x
  • 9, 15, 33, 87, 249
  • (4, 87) for example

Step-by-step explanation:

a) First differences of the f(x) values in the table are ...

  19 -13 = 6, 37 -19 = 18, 91 -37 = 54, 253 -91 = 162

The second differences are not constant:

  18 -6 = 12, 54 -18 = 36, 162 -54 = 108

But, we notice that both the first and second differences have a common ratio. This is characteristic of an exponential function. The common ratio is 18/6 = 3, so the parent function is 3^x.

__

b) Translating a function down 4 units subtracts 4 from each y-value. The values of f(x) in the table would be ...

  9, 15, 33, 87, 249

__

c) The x-values of the function stay the same for a vertical translation, so the points in the table of the transformed function are ...

  (x, f(x)) = (1, 9), (2, 15), (3, 33), (4, 87), (5, 249)

Find the value of x pls
Basile [38]

Step-by-step explanation:

As we can see it a right angled triangle

so <y =90°

Now

3x + 11° + 25° + 90° = 180°{being sum of angles of triangle}

3x + 126° = 180°

3x = 54°

X = 18°
