For this case we have that according to the method of algebraic resolution PEMDAS the following order is fulfilled:

P: Parenthesis

E: Exponents

MD: Multiplication and division (From right to left)

AS: Addition and subtraction (From right to left)

So, if we have the following expression:

8-2 [6-4: (9-7)] =\\8-2 [6-4: 2] =\\8-2 [6-2] =\\8-2 [4] =\\8-8 =\\0

Answer:

8-2 [6-4: (9-7)] = 0

Kayden is the youngest of four siblings whose ages are consecutive integers. if the sum of their ages is 90, find kayden's age.
NISA [10]

Based on the fact that Kayden is the youngest and their ages are consecutive and add up to 90, the Kayden is 21.

<h3>How old is Kayden?</h3>

To find Kayden's age, assume that it is x and use the formula:

90 = x + (x + 1) + (x +2) + (x +3)

Solving for x gives:

90 = 4x + 6

4x = 90 - 6

x = 84 / 4

x = 21

Find the equation of the linear function represented by the table below in slope-intercept form.
Ilya [14]

Answer:

the desired equation is y = x + 4.

Step-by-step explanation:

Slope is defined as m = rise over run.  Run is the change (usually an increase) in x, and rise an increase or decrease in y.

We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5).  Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.

Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:

5 = 1(1) + b, or b = 4.

Therefore the desired equation is y = x + 4.
