Yes

0.2x = 2.6 so 5 times each side gives x = 13

just multiply it,and it equals 40.

(2,-2)

This is a case where we can apply l'Hopital's rule, separately calculating the derivatives of the numerator and denominator, then take the limit using those:

Limx→2 [(6 - x)1/2 - 2] / [(3 - x)1/2 - 1]

= Limx→2 [1/2(6 - x)-1/2 (-1)] / [1/2(3 - x)-1/2 (-1)]

= Limx→2 (3 - x)1/2 / (6 - x)1/2

= 1/2

NONE

3X+70-7*18=0

3X+70-126=0

3X-56=0

3X=56

x=56/3 or 18.6667

No.

3j-13=11+2j

3j-13-2j = 11+2j-2

j-13 = 11

j-13 +13 = 11 + 13 = 24

so j = 24

The curve must have a derivative at every point (except its end point).

It is zero

1 cm3 = 1000 mm3

because if 1 cm = 10 mm, 1 cm3 = 103 mm3

1.71 meters = 67.3228346 inches

or x + y = 6

That cannot be simplified further and to solve for either variable will require another independent eqaution in x and y

9x+8=7x+22

To solve for x, combine like terms. (Subtract 7x from both sides, and subtract 8 from both sides. This will give you:

2x=14

Divide both sides by 2. The answer is x=7.

3.14

No.

5x5x5x5x5x5=15,625.

Either the answer is

the point in the second quadrant, at a distance of one unit from each of the coordinate axes, or

the question is incomplete.

The Y means the y co-ordnate in an ordered pair.

Let s = sin x; c = cos x.

By definition,

sec x = 1/cos x = 1/c; and

tan x = (sin x) / (cos x) = s/c.

We know, also, that s2 + c2 = 1.

Then, dividing through by c2, we have,

(s2/c2) + 1 = (1/c2), or

(s/c)2 + 1 = (1/c)2; in other words, we have,

tan2 x + 1 = sec2 x.

7 - 2x

(x+12)(x-4)

The answer to f x x-5 x plus 3 standard form is -6. This is a math problem.
