Simplify the expression (k2)4

1 answer:

6 0

4 times 2= 8. so, 4times k2 = k8. To understand this better, imagine that k equaled 2. That would make the expression above = (2x2)4, which would equal 16. However, since we don't know the value of k, we have to use the numbers that we already have, It would be like solving the expression: (2x2)4 without multiplying the first 2. It would then be 2x8. So, we just simplified it, we didn't solve it.

Find the equation of a line that is parallel to the line x equals negative 1x=−1 and contains the point left parenthesis negativ

sineoko [7]

The equation of the line is given as $y-x=-1$

A straight line equation is given in the form $y=mx+c$ where $m$ is the gradient and $c$ is the y-interest.

We need to rearrange $y-x=-1$ to make $y$ the subject.
$y= x-1$ ⇒ from here we can read the gradient and the y-intercept. The gradient, $m=1$ and $c=-1$ .

<span>A line that is parallel to $y=x-1$ will have the same gradient, $m=1$ but different y-intercept. One example of equation of a line that is parallel to $y=x-1$ is $y=x+3$
