Answer:
[tex]16x^2+4x+1[/tex]
Step-by-step explanation:
Given expression:
[tex]\dfrac{64x^3-1}{4x-1}[/tex]
Step 1Factor the numerator of the given expression.
Rewrite 64 as 4³ and 1 as 1³:
[tex]\implies (4^3)x^3-1^3[/tex]
[tex]\textsf{Apply the exponent rule} \quad a^b \cdot c^b=(ac)^b:[/tex]
[tex]\implies (4x)^3-1^3[/tex]
[tex]\textsf{Apply the Difference of Cubes Formula} \quad x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right):[/tex]
[tex]\implies (4x)^3-1^3=(4x-1)\left((4x)^2+4x(1)+(1)^2\right)[/tex]
[tex]\implies (4x)^3-1^3=(4x-1)\left(16x^2+4x+1\right)[/tex]
Step 2Replace the numerator in the given expression with the factored numerator from step 1:
[tex]\implies \dfrac{64x^3-1}{4x-1}=\dfrac{(4x-1)\left(16x^2+4x+1\right)}{4x-1}[/tex]
Cancel the common factor (4x - 1):
[tex]\implies 16x^2+4x+1[/tex]
8(5-2x)=24
Solve x. Pls show working
distribute the terms
-16x+40=24
subtract 40 from both sides
-16x - -16
divide both by 16
x = 1

Evaluate: 42 − 12 ÷ 6
—————————————————
(6 − 3) × 4 − 7
Answer:
42 - 12 ÷ 6 = 40
(6 - 3) x 4 - 7 = 5
Step-by-step explanation:
First of all, when coming over to an equation with a division or multiplication sign, we first solve the division or multiplication first, then the subtraction or addition. So, 12 ÷ 6 = 2. Then, 42 - 2 = 40. And in the other one we must first solve what's in the parenthesis. So, 6 - 3 = 3. Then, we multiply, 3 x 4 = 12. Then subtract. 12 - 7 = 5.

Write an equation with a slope: -3/4 and y-intercept: -1/4
Answer:
y = (-3/4)x - 1/4
Step-by-step explanation:
Use the slope-intercept formula y = mx + b. Here m = -3/4 and b = -1/4, and so: y = (-3/4)x - 1/4
The equation of the line with slope -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of the line is the ratio of the rise to the run, or rise divided by the run.
It describes the steepness of line in the coordinate plane.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given that the slope is -3/4 and y-intercept is -1/4.
We have to find the equation of line with slope -3/4 and y-intercept is -1/4.
m=-3/4 and b = -1/4
Now plug in these values in slope intercept form y=mx+b
y=-3/4x-1/4
Hence, y=-3/4x-1/4 is the equation of the line with slope -3/4 and y-intercept is -1/4.

Which of the following points best represents the location of -1 5/8 on the number line?
Answer:
A
Step-by-step explanation:
Looking at the number line, you will notice that A, B, and C are less than 0.
Eliminate D, which is greater than 0.
Further still, as negative numbers get 'smaller', they go from -1 to -∞.
i.e.: -1 > -2 > -3
if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.
Then, simply counting the ticks from -1 to -2, you can see that A falls on the 5th tick, while -2 falls on the 8th tick from -1.
Hope this helped.
Answer:
A
Step-by-step explanation:
-1 5/8 would be between -2 and -1

write another expression describing the number of shoes available for each retail store if the shoes are divided equally among stores.
Answer: 20c + 10.
Step-by-step explanation:
(c represents crates)
I wrote each equation separately first.
Supplier A: 4c + 6
Supplier B: 6c - 1
Supplier C: 10c + 5
We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )
