Which expression represents this word phrase? seven less than the quotient of x and 9 x−7 9 x÷ 9 7 (x÷9)−7 (9÷x)−7

1 answer:

6 0

Quotient of x and 9 is $\frac{x}{9}$ because we can find quotient by division.
Now we have to less 7 from this quotient.

So we can write it as

$\frac{x}{9} - 7$

So we can say third option is correct.

Sam’s two new aquariums each hold exactly 200 gallons of water. One aquarium will hold small fish and the other will hold large

Gre4nikov [31]

Okay so you have to do 5 times 10 then you will have to do 8 time 8 times 40 so after you get your answer you would do the ratio 50 to 320 50:320

erik drove 439.92 miles on 15.6 gallons of gas. To the nearest hundredth, how many miles could he drive on 39.7 gallons of gas?

zaharov [31]

First you divide 439.92 by 15.6 and you get 28.2 which is how many miles per gallon that you are getting. Then you take 28.2 and multiply it by how many gallons that it says (39.7) The final answer is 1119.54

Identify the quadratic function(s). (Select all that apply.)

Katen [24]

General Idea:

The quadratic function of the form $ax^2+bx+c=0$ .

Applying the concept:

Simplifying the equation in option A, we get...

$A) \; 8 - 5x = 4(3x - 1) \\Distributing \; 4 \; in \; right \; side \; of \; the \; equation. \\ \\ 8 - 5x = 12x - 4\\ The \; equation \; is \; a \; linear \; equation \; with \; variable \; on \; both \; sides.$

Simplifying the equation in option B, we get...

$B) \; \; (4a + 2)(2a - 1) + 1 = 0\\ Multiplying \; First \; \; Outer \; \; Inner \; \; Last \; terms\; in\; the \; left \; side.\\ \\ 4a \cdot 2a + 4a \cdot -1 + 2 \cdot 2a + 2 \cdot -1 + 1 = 0\\ \\ 8a^2-4a+4a-2+1=0\\ Combining \; like \; terms \; \\ \\ 8a^2 - 1 = 0\\ Above \; is \; a \; Quadratic \; Equation!$

Simplifying the equation in Option C, we get...

$C)\; \; 2y + 2(3y - 5) = 0\\ Distributing \; 2 \; in \; left \; side\\ \\ 2y+6y-10=0\\ Combining \; like \; terms\\ \\ 8y - 10 = 0\\ Above \; Equation \; is \; linear \; equation$

Simplifying the equation in Option D, we get

$D) \;2b(b - 7) + b = 0\\ Distributing \; 2b\; in \;the \;left\; side \;of \;the\;equation\\ \\ 2b \cdot b - 2b \cdot 7+b=0\\ Simplify \; in \; the \; left \; side \; of \; the \; equation\\ \\ 2b^2-14b+b=0\\ Combine \; like \; terms\\ \\ 2b^2-13b=0\\ Above \; equation \;is \;a \; Quadratic\;Equation!$

<u>Conclusion:</u>

Option B) & Option D) are quadratic equation!

Solve for d. ad - bc = f

WARRIOR [948]

Ad - bc = f......for d
add bc to both sides
ad = f + bc
divide both sides by a
d = (f + bc) / a
