Alicia is solving the equation 2.3 x minus 1.6 = 8.8 minus 2.9 x. Which equations represent possible ways to begin solving for x? Check all that apply.
2.3 x minus 10.4 = negative 2.9 x
5.2 x minus 1.6 = 8.8
Negative 6.5 x minus 1.6 = negative 2.9 x
2.3 x + 1.3 = 8.8
2.3 x = 10.4 minus 2.9 x

Answers

2.3 x - 1.6 = 8.8 - 2.9 x

+ 1.6 +1.6

2.3 x = 10.4 - 2.9 x

2.3 x - 1.6 = 8.8 - 2.9 x

-8.8 - 8.8

2.3 x - 10.4 = 2.9 x

2.3 x - 1.6 = 8.8 - 2.9 x

+2.9 x + 2.9 x

5.2 x -1.6 = 8.8

hope this helped :3

Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).

Answers

Answer: 147

Step-by-step explanation:

To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).

f(3)=2(3)²-4(3)+9         [exponent]

f(3)=2(9)-4(3)+9          [parenthesis]

f(3)=18-12+9                [subtract]

f(3)=6+9                       [add]

f(3)=15

Now, we find f(-3).

f(-3)=2(-3)²-4(-3)+9      [exponent]

f(-3)=2(9)-4(-3)+9         [parenthesis]

f(-3)=18+12+9               [add]

f(-3)=30+9                    [add]

f(-3)=39

With the values of f(3) and f(-3), we can evaluate the expression.

2(15)+3(39)                  [multiply]

30+117                          [add]

147

Now, we know the value is 147.

You would take any big y number and use it as your y2 go up one use it as your y1 subtract it that’s your numerator. Next take your big x2 across from your y2 and then use the one across from y1 and subtract those that’s your denominator!

Step-by-step explanation:

Using the rules of exponents, this simplifies to ...

  [tex](2x^2)^3 = 2^3x^{2\cdot3}=8x^6=\boxed{8\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}[/tex]

The applicable rules of exponents are ...
