It’s d, 1 - t

t + 3 - 2 - 2t
we can rearrange it as
t - 2t + 3 - 2
-t + 1 is the same as 1 - t

Question 10 of 21

PSYCHO15rus [73]

ANSWER

A. (4,12)

EXPLANATION

The equations are:

$10x +2y = 64...(1)$

and

$3x - 4y = -36...(2)$

To eliminate a variable we make the coefficients of that variable the same in both equations.

It is easier to eliminate x.

We multiply the first equation by 2 to get:

$20x + 4y = 128...(3)$

We add equations (2) and (3).

$3x + 20x + 4y - 4y = - 36 + 128$

$23x = 92$

Divide both sides by 23

$\frac{23x}{23} = \frac{92}{23}$

$x = 4$

Put x=4 into equation (1).

$10(4)+2y = 64$

$40+2y = 64$

$2y = 64 - 40$

$2y = 24$

$\frac{2y}{2} = \frac{24}{2}$

$y = 12$

The solution is (4,12)

10 to the power of 4 as a decimal

Nonamiya [84]

Answer:

You treat it as 10^4 (the small number is the number of zeros. Therefore the answer is 10000. Or of you meant 10^-4. Its the same concept, just reversed. So the answer in this case is 0.0004.

Cheers! :)
