HELP PLZ ILL MARK YOU AS BRAINLES

So to compare boxes, you want to convert both to price per ounce unit.

So for smaller box, we have ratio $2.89 / 17 ounces which can be reduced to $0.17 per ounce. You just divide 2.89 by 17.

Now for larger box, we have ratio $3.29 / 24 ounces which can be reduced to approximately $0.14 per ounce. 0.137083333... to be exactly.

Larger box has smaller ratio compared to smaller box therefore larger box the is better buy.

The difference per ounce is 0.17 - 0.137083333... = 0.03291666... so that's 3.3 cents cheaper per ounce.

Final answer: <span>The larger box is the better buy because it is approximately 3.3 cents cheaper per ounce.</span>

Which form of a quadratic function is easiest to use when finding the maximum or minimum value of the function?

alexandr402 [8]

Answer:

ax² + bx + c

Step-by-step explanation:

The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.

Suppose a quadratic function:

f(x) = 2x² - 8x + 9

Use ( -b/2a , f(-b/2a) ).

-b/2a

a = 2

b = -8

-(-8)/2(2)

8/4

= 2

f(2) = 2(2)² - 8(2) + 9

f(2) = 2(4) - 8(2) + 9

f(2) = 8 - 16 + 9

f(2) = 1

The minimum value of this quadratic function is (2, 1).

It represents a minimum value because a > 0.

Solve 3^x−5 = 9. (3 points) Select one: a. x = −3 b. x = 2 c. x = 7 d. x = 8

goldfiish [28.3K]

ANSWER

C. x=7

EXPLANATION

The given exponential equation is

${3}^{x - 5} = 9$

We rewrite the right hand side as 3 raised to exponent 2.

${3}^{x - 5} = {3}^{2}$

Observe that the base of both sides of the equation are equal.

We now equate the exponents.

$x - 5 = 2$

Solve for x,

$x = 2 + 5$

$x = 7$

The correct choice is C.

Colton and Gage were building a castle together. Colton was 5 times as fast at building the castle than Gage. If it takes 120 bl

ira [324]

Answer:

100 blocks.

Step-by-step explanation:

Let x represent number of blocks built by Gage.

We have been given that Colton was 5 times as fast at building the castle than Gage, so number of blocks built by Colton would be $5x$ .

We are also told that it takes 120 blocks to build the castle. Since Colton and Gage were building a castle together, so number of blocks built by both will be equal to 120.

$x+5x=120$

$6x=120$

$\frac{6x}{6}=\frac{120}{6}$

$x=20$

Number of blocks built by Colton: $5x=5\cdot 20=100$ .

Therefore, Colton had build 100 blocks.
