What is 12^(2x-8)=15
IgorLugansk [536]
12(2x - 8) = 15
12(2x) - 12(8) = 15
24x - 96 = 15
<u>      + 96 + 96</u>
       <u>24x</u> = <u>111</u>
        24      24
           x = 4.625

The table shows the relationship between the amount of money (y) remaining in Maddy's money box and the number of months (x): Fu
algol13
Maddie :
(1,100),(2,80)
slope (rate of change) = (80 - 100) / (2 - 1) = -20/1 = -20

Caitlin :
y = -18x + 120......slope (rate of change) = -18

To determine which rate of change is greater, take the absolute value of the slopes.
 Maddy : | -20 | = 20
Caitlin : | -18 | = 18
 the greater rate of change is the one with the larger absolute value....so that would be Maddy...function 1 shows a greater rate of change because Maddie spends 20 each month and Caitlin spends 18 each month

Evaluate the expressions 3x-2 and 4x+4 for the following value of x.
kirill [66]

Question:

Evaluate the expressions 3x - 2 and 4x + 4 for the following values of x. When you have found the value for each expression, write a statement using <, >, or = that shows how the two values are related. a. x = 0 b. x = -6 c. x = 5 d. x = -2

Answer:

Part a: 4x+4>3x-2

Part b: 4x+4=3x-2

Part c: 4x+4>3x-2

Part d: 4x+4>3x-2

Explanation:

Part a: Substituting x=0, we get,

\begin{aligned}3 x-2 &=3(0)-2 \\&=-2\end{aligned}

\begin{aligned}4 x+4 &=4(0)+4 \\&=4\end{aligned}

The value of 3x-2 is less than 4x+4

Thus, 4x+4>3x-2

Part b: Substituting x=-6, we get,

\begin{aligned}3 x-2 &=3(-6)-2 \\&=-18-2 \\&=-20\end{aligned}

\begin{aligned}4 x+4 &=4(-6)+4 \\&=-24+4 \\&=-20\end{aligned}

The value of 3x-2 and 4x+4 are equal.

Thus, 4x+4=3x-2

Part c: Substituting x=5, we get,

\begin{aligned}3 x-2 &=3(5)-2 \\&=15-2 \\&=13\end{aligned}

\begin{aligned}4 x+4 &=4(5)+4 \\&=20+4 \\&=24\end{aligned}

The value of 3x-2 is less than 4x+4

Thus, 4x+4>3x-2

Part d: Substituting x=-2, we get,

\begin{aligned}3 x-2 &=3(-2)-2 \\&=-6-2 \\&=-8\end{aligned}

\begin{aligned}4 x+4 &=4(-2)+4 \\&=-8+4 \\&=-4\end{aligned}

The value of 3x-2 is less than 4x+4

Thus, 4x+4>3x-2
