Hello!

You can only add variables with the same base and exponent

8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9

Put the sums together

12u^3 + 8u^2 - 6u + 9

The answer is D) 12u^3 + 8u^2 - 6u + 9

Hope this helps!

Given: 18x-2(3x+1)=5x-16<br> Prove: x=-2
zlopas [31]

Answer:

True

Step-by-step explanation:

Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:

-2×18 - 2 (1 - 2×3) = -2×5 - 16

3 (-2) = -6:

-2×18 - 2 (-6 + 1) = -2×5 - 16

1 - 6 = -5:

-2×18 - 2-5 = -2×5 - 16

18 (-2) = -36:

-36 - 2 (-5) = -2×5 - 16

-2 (-5) = 10:

10 - 36 = -2×5 - 16

5 (-2) = -10:

10 - 36 = -10 - 16

10 - 36 = -26:

-26 = -10 - 16

-10 - 16 = -26:

-26 = -26

-26 is equal to -26:

Answer:  True

svp [43]

Answer:

$31.88

Given

Consumer charges = 2530.16cents

Consumer charges in dollars = $25.3016

Interest rate per day = 0.042%

Interest gotten per day = 0.042×25.3016

Answer:

Option (C)

Step-by-step explanation:

Cost of ordering the number of shirts is represented by the function,

f(x) = 12.75x + 3.5

where x = number of players in the bowling team

Since number of players a bowling team can have,

6 ≤ x ≤ 10

Therefore, domain of the function: 6 ≤ x ≤ 10

For x = 6,

f(6) = 12.75(6) + 3.5

     = 80

For x = 7,

f(7) = 12.75(7) + 3.5

     = 92.75

For x = 8,

f(8) = 12.75(8) + 3.5

     = 105.5

For x = 9,

f(9) = 12.75(9) + 3.5

     = 118.25

For x = 10,

f(10) = 12.75(10) + 3.5

      = 127.5 + 3.5

      = 131

Therefore, for the given domain range of the function will be,

Range : {80, 92.75, 105.5, 118.25, 131}

Option (C) will be the answer.
