Natalka [10]

$0.25 X 10,000 = $2500.
We now know what the total sales price per tile sold was $2500.

$3000
-$2500
=$0500

We now know that the flat fee was $500.

Therefore the equation describing the revenue of the tile from this sale in terms of tiles sold is y = 0.25x + 500
The answer is C)

Answer: $\frac{150}{31}$

<u>Step by step explanation:</u>

log₆(5x + 6) - log₆(x - 4) = 2

log₆ $(\frac{5x+6}{x-4})$ = 2

$(\frac{5x+6}{x-4})$ = 6²

$(\frac{5x+6}{x-4})$ = 36

5x + 6 = 36(x - 4)

5x + 6 = 36x - 144

6 = 31x - 144

150 = 31x

$\frac{150}{31}$ = x

Answers:

a. (-1, -5)
b. up
c. x = -1
d. $\frac{-2+\sqrt{15}}{3} and\frac{-2-\sqrt{15}}{3}$
e. -2
f. see attachment
g. domain (-∞, ∞) range [-5, ∞)

<u>Explanation:</u>

f(x) = 3x² + 6x - 2

a=3 b=6 c=-2

x = $\frac{-b}{2a} =\frac{-6}{2(3)} = \frac{-6}{6} = -1$

Axis Of Symmetry: x = -1

f(-1) = 3(-1)² + 6(-1) - 2

= 3 - 6 - 2

= -5

Vertex: (-1, -5)

x = $\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

= $\frac{-6+/-\sqrt{6^{2}-4(3)(-2)}}{2(3)}$

= $\frac{-6+/-\sqrt{36+24}}{6}$

= $\frac{-6+/-\sqrt{60}}{6}$

= $\frac{-6+/-2\sqrt{15}}{6}$

= $\frac{-2+/-\sqrt{15}}{3}$

x-intercepts: $\frac{-2+/-\sqrt{15}}{3}$

Dom made Halloween cookies for her class. For every 2/3 cup of flour, she made 2 dozen cookies. Write and equation that represen

DIA [1.3K]

The answer is 10/3
The explanation 2 1/3 cu of flour/ 3 1/2 dozen of cookies = X unknown cu. of flour/ 5 dozen cookies

Cross multiply

3 1/2 X = 5 (2 1/3) Change the mixed numbers into improper.

7/2 X = 5 ( 7/3) Solve for "X." Multiply both sides of equation by reciprocal of 7/2, which is 2/7

(2/7 (7/2)X = 5 (7/3)(2/7) X= 10/3 =Just divide 10 by 3. You should get a whole number
