How do u solve the following equation: |r|=1

1 answer:

7 0

You're almost looking at the solution. Almost.

If it only said " r = 1 ", then that would be the solution right there.

But it says " | r | = 1 ", so there's a little more to it.

'r' can be either +1 or -1 and that equation will be a true statement.

So +1 and -1 are both solutions.

Hi!

Let's find out how much he has to pay for each of the deals.

Deal 1

£1.75 per mile.

192 x 1.75 = 336

£336

Deal 2

15% off of £680

$\frac{x}{680} \frac{15}{100}$

680 x 15 = 10200

10200/100 = 102

680 - 102 = 578

£578

Deal 3

£90 per day - 1/10

90 x 7 = 630

1/10 of 630 = 63

630 - 63 = 567

£567

The cheapest deal would be Deal 1

Hope this helps! :)

Complete the explanation of the procedure that can be used to solve 5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55. Then solve the e

Debora [2.8K]

Answer:

x = 2.

Step-by-step explanation:

5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55

5[3x + 12 - 2 + 2x] - x - 15 = 14x + 55

5[5x + 10] - x - 15 = 14x + 55

25x + 50 - x - 15 = 14x + 55 Now we subtract 14x from both sides:

25x + 50 - x - 15 - 14x = 14x - 14x + 55

10x + 50 - 15 = 55 Now we subtract 50, add 15 to both sides:

10x + 50 - 50 - 15 + 15 = 55 - 50 + 15

10x = 20

x = 2.

Number 2 says Write the given equation in exponential form. Log8 1/512=-3

MA_775_DIABLO [31]

In exponential form it is given as, 8⁻³ = $$\frac{1}{512}$

Step-by-step explanation:

We have to write the given equation in the exponential form, that is in the form of base to the power value.

Given:

log₈ ( $$\frac{1}{512}$ ) = -3

Here the base is 8.

In the exponential form, it is written as,

base to the power 3 = 512

Here the reciprocal of 512 is given, so,

base to the power -3 = $$\frac{1}{512}$

So the exponential form is given as, 8⁻³ = $$\frac{1}{512}$

ROTATIONS ; GEOMETRY. PLEASE HELP AND INCLUDE AN EXPLANATION IF POSSIBLE

Troyanec [42]

Rotation 90° translates (x, y) to (-y, x). Thus (3, 2) gets translated to (-2, 3). Your green box gets filled with -2.
