Answer:

(a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3.

Answer:

Step-by-step explanation:

(a-b)^3

(a-b)(a-b)(a-b)

a^3-3a^2b+3ab^2-b^3

Answer:

-6(3x +2) = 2x -5 -20x -7 (use the distributive property )

-18x -12 = -18x - 12 (i combined like terms on the right side of the equation)

at this point I can tell that it's true for any value of x, so they all apply

Step-by-step explanation:

Answer:

yes it can

Step-by-step explanation:

Answer:

Yes, m can be a fraction.

Step-by-step explanation:

m in y=mx+b stands for slope, and slope is rise/run, so it most definitely can be a fraction. BUT, keep it as 5/4 or 1.25 when writing it so you don't confuse yourself next time ;)

Answer:

y = 410

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

y = 23x - 4

x = 18

Step 2: Evaluate

Answer:

y = 410

Step-by-step explanation:

y = 23x - 4    If x = 18

y = (23*18) - 4

y = 414 - 4

y = 410

Answer:

It has to be the third option.

Happy to help :)

Answer:

C

Step-by-step explanation:

Answer-

B) 40

Step By Step Intrustions-

First Step-

Gather your important numbers; 60, 3.75, & 2.5

Second Step [ Divide ]-

Divide your numbers for the same side;

60 ÷ 3.75 = 16

Final Step [ Multiply ]-

16 × 2.5 = 40

40 is your final answer of the enlarged side. Hope this helps!

Answer:

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Step-by-step explanation:

Given that:

Distance covered = 4/5 of a mile

Time taken to cover the distance = 1/3 of an hour

Speed is defined as the distance travelled in a certain time.

Speed of Janiya = [tex]\frac{Distance}{Time}[/tex]

Speed of Janiya = [tex]\frac{\frac{4}{5}}{\frac{1}{3}}[/tex]

Speed of Janiya = [tex]\frac{4*3}{5*1}[/tex]

Speed of Janiya = [tex]\frac{12}{5}[/tex]

Speed of Janiya = [tex]2\frac{2}{5}[/tex] miles per hour

Hence,

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

so it 15

Step-by-step explanation:

Answer:

The y-intercept of the line is -4.

Step-by-step explanation:

y-y=m(x-x¹)

y-(-2)=-1(x-(-2))

y+2=-1x-2

-2 -2

y=-1x-4

I dont know sorry

So sorry really wish i could help

Answer:

C)

Step-by-step explanation:

The highest point on the graph for c) is in the first quadrant (where x=2 would be).

If you had an equation, you would be able to find critical points on the function by setting the numerator and denominator equal of f'(x)=0 and solve. You'd have to evaluate f(x) at these critical points and end points to figure that out. This is, if you're in calculus and you would ever need assistance otherwise!

Answer:

3

Step-by-step explanation:

65-23= 42

42/14= 3

Answer:

14x+23 =65 x=3CDs

Step-by-step explanation:

So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.

To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

I hope this helps.

Step-by-step explanation:

soln:

given,

17/10 bags=1 day

64/5 bags= ?

we know,
