C. x³ - x²

In word problems, there terms which indicate the mathematical operation that needs to be performed.

difference = refers to the answer in subtraction
triple a number or double a number refers to the number of times a number is multiplied by itself.

in triple a number = a number is multiplied by itself three times.
in double a number = a number is multiplied by itself two times.

It would initially look like this: (x * x * x) - (x * x); to simplify the expression, a number to be multiplied is written down and the number of times it will multiply by itself is noted on the upper right side of the number when we look at it.

Thus: x³ - x² is the correct expression that best describes the word problem above.

The verified answer is incorrect. I had this question on USA Test Prep just now, and the correct answer to the question is 3x - 2x.

The number of blue fish to red fish in a tank is

Lena [83]

51 blue fish.

If there is 34 to 50 blue to red fish in tank A. Then tank B is 51 to 75. Because 75 is 1.5 times larger than 50 you have to multiply 34 by 1.5 to get 51.

Please answer!!

HACTEHA [7]

Answer:

See below

Step-by-step explanation:

$f(x)=3x^2+6x-24\\\\f(x)=3(x^2+2x-8)\\\\f(x)+3(9)=3(x^2+2x-8+9)\\\\f(x)+27=3(x^2+2x+1)\\\\f(x)=3(x+1)^2-27$

Here, we can see that the vertex of the parabola is $(-1,-27)$ when we compare to the equation $y=(x-h)^2+k$ with vertex $(h,k)$ .

A second point you could plot is the y-intercept, when $x=0$ :

$f(0)=3(0+1)^2-27\\\\f(0)=3-27\\\\f(0)=-24$

So, your y-intercept is $(0,-24)$ .

Jackie bought a 3-pack of tubes of glue. She used 0.27 ounce of the glue from the 3-pack

brilliants [131]

Answer:

0.54 ounces in each tube

Step-by-step explanation:

Add the amount she used so we can add it in. 1.35+0.27= 1.62. Then divide it by the number of tube and since it was a 3 pack you divide it by 3. 1.62/3=0.54 so there is 0.54 ounces in each tube.

What is the equation of the line described below written in slope-intercept form?

vladimir1956 [14]

Answer:

y=1x+2 or y=x+2

Step-by-step explanation:

We know that the slope is going to be one since the slopes of parallel lines are equal and the other equation has a slope of 1. We can then use the equation y=1x+b and the point given, (2,4), to find the y-intercept, b. You plug in (2,4) as your x and y values to get 4=1(2)+b. You can then solve this by multiplying to get 4=2+b, then subtracting 2 from both sides to get b=2. We can then use b to complete the equation as y=1x+2 or y=x+2.
