$\\ \sf\longmapsto (3x-2x^2+3)-(-5x^2+3x+5)$

$\\ \sf\longmapsto 3x-2x^2+3+5x^2-3x-5$

$\\ \sf\longmapsto 5x^2-2x^2+3x-3x+3-5$

$\\ \sf\longmapsto 3x^2-2$

If y varies inversely as X and Y equals 5 when x equals 3 find X when Y is 15

omeli [17]

Answer:

x = 1

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 5 when x = 3

k = yx = 5 × 3 = 15, thus

y = $\frac{15}{x}$ ← equation of variation

When y = 15 then

15 = $\frac{15}{x}$ ( multiply both sides by x )

15x = 15 ( divide both sides by 15 )

x = 1

Find the missing side of the triangle

Katena32 [7]

$\\ \sf\longmapsto sin\theta=\dfrac{Perpendicular}{Hypotenuse}$

$\\ \sf\longmapsto sin74=\dfrac{n}{40}$

$\\ \sf\longmapsto n=40sin74$

$\\ \sf\longmapsto n=35(0.96)$

$\\ \sf\longmapsto n=38.4$

What is the greatest common factor of 36x^3 and 8x

marusya05 [52]

Factor 36x^3 = (2)(2)(3)(3)(x)(x)(x)
Factor 8x = (2)(2)(2)(x)

Take what they have in common which is (2)(2)(x) and multiply and it will be 4x.

Use quadratic formula to solve 1-6x^2-x

eduard

Answer:

(3x-1)(2x+1)

Step-by-step explanation:

1-6x^2-x=0

-6x^2-x+1=0

6x^2+x-1=0

6x^2+(3-2)x-1=0

6x^2+3x-2x-1=0

3x(2x+1)-1(2x+1)=0

(3x-1)(2x+1)=0

So the factor is (3x-1)(2x+1)
