2x²/x⁴=8
2(x²/x⁴)=8
2(1/x²)=8
2=8x²
x²=2/8
x²=1/4
x=⁺₋√(1/4)
x=⁺₋1/2

Answer: we have two solutions: -1/2 and 1/2

The x^2 cancels
\frac{2x^2}{x^4} =8
\frac{2}{x^2} =8
times both sides by x^2
2=8x^2
divide both sidesby 8
1/4=x^2
sqrt both sides
+/-1/2=x


x=-1/2 and 1/2

Answer:

10

Step-by-step explanation:

C = 0.75 + L

For L = 3 ; Cost, C = 3.75

3.75 = 0.75 + 3L

3.75 - 0.75 = 3L

3 = 3L

L = 3/3

L = $1

C = 0.75 + 1L

If amount spent is $10.75; C = 10.75

10.75 = 0.75 + L

10.75 - 0.75 = L

10 = L

Number of letters = 10

FIND THE VERTEX AND GRAPH THE PARABOLA OF
DochEvi [55]

════════ ∘◦❁◦∘ ════════

<h3>Answer : (-2,11)</h3>

════════════════════

<h3>Known that</h3>

y = -2x² - 8x + 3

════════════════════

<h3>Way to do + explanation</h3>

#First, find the x coordinate first by using the formula of -b/2a

x = -b/2a = -(-8)/2(-2) = 8/-4 = -2

#After getting the x, find the y

y = -2(-2)² - 8(-2) + 3

y = -2×4 +16 + 3

y = -8 + 16 + 3

y = 11

So the vertex is

(-2,11)

Answer:

2(x - 9.46)(x + 2.54)

Step-by-step explanation:

2(x² - 12x + 24)

since there are no factors that multiply to 24 and add to -12 then i used the quadratic formula to get:

6+2\sqrt{3}, 6-2\sqrt{3}

What is the total price on a suit which sells for $490.50 if the tax is 8%?
daser333 [38]

Answer:

The total price is $529.74

Step-by-step explanation:

This question is an example of percentage increase.

To work out the total price you would first have to convert the percentage into a decimal. You can do this by dividing the percentage of 8% by 100, this gives you 0.08. This is because percentages are out of 100.

The next step is to add the value of 0.08 and 1, this gives you 1.08. This is because you are working out the percentage increase.

The final step is to multiply the amount of $490.50 by the value of 1.08, this gives you $529.74. This is because we are finding the percentage increase of 8%.

1) Divide 8 by 100.

8/100=0.08

2) Add 0.08 by 1.

1+0.08=1.08

3) Multiply $490.50 by 1.08.

490.50*1.08=529.74
