Which of the following is a function equivalent to f(x) = 3(1.7)4x? (5 points) f(x) = 25.06x f(x) = 3(8.35)x f(x) = 3(8.25x) f(x

Answer:

Step-by-step explanation:

Given: f(x) = 3(1.7)4x

This can also be looked at as: f(x) = 3 × 1.7 × 4 × x

You can multiply the three values four different ways and they will all be equivalent.

f(x) = (3 × 1.7) × 4 × x = 5.1(4)x

f(x) = 3 × (1.7 × 4) × x = 3(6.8)x

f(x) = 1.7 × (3 × 4) × x = 1.7(12)x

f(x) = 3 × 1.7 × 4 × x = 20.4x

Assuming 2x2 is $2x^{2} 
$ you would get 2(2.5)(2.5) - 3(2.5) +7, which is 2(6.25) - 7.5 + 7, 12.5 - 0.5, [12]

A chef plans to mix 100% vinegar with Italian dressing. The Italian dressing contains 12%

Hitman42 [59]

Answer:

Amount of vinegar. 100% : 20 milliliters

Amount of Italian dressing: 140 milliliters

Step-by-step explanation:

Let's call A the amount of vinegar. 100%

Let's call B the amount of Italian dressing . 12% vinegar

The resulting mixture should have 23% vinegar, and 160 milliliters.

Then we know that the total amount of mixture will be:

$A + B = 160$

Then the total amount of pure antifreeze in the mixture will be:

$A + 0.12B = 0.23 * 160$

$A + 0.12B = 36.8$

Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation:

$-A -B = -160$

$A + 0.12B = 36.8$

--------------------------------------

$-0.88B = -123.2$

$B = \frac{-123.2}{-0.88}$

$B = 140\ milliliters$

We substitute the value of B into one of the two equations and solve for A.

$A + 140 = 160$

$A = 20\ milliliters$
