Is X=3 calculate the value of X3+X btw the 3 is a small three

Naddik [55]

The only 'small number' that I know that would affect the answer is an exponent that looks like ³ so the problem would be x³+x

remember that x³=x times x times x
if x=3 then
3³+3=27+3=30

√2+1<br> b) Rationalize the denominator:<br> √2+1

Misha Larkins [42]

Answer:

there is not a complete question here ...

$\sqrt{2} +1$ is not in a denominator to rationalize

if it were you would multiply the rational expression (the fraction)

by $\frac{\sqrt{2} -1}{\sqrt{2} -1}$ the result (in the denominator would end up being "2 -1"

which is 1

122. Write the equation of the line that is

Marina CMI [18]

When a line is given in the form

$y=mx+q$

The slope of the line is m. So, in this case, the slope of $y=x-5$ is 1.

Given a slope $m$ , you find the slope of a perpendicular line $m'$ by imposing

$m\cdot m' = -1$

So, if the given line has slope 1, a perpendicular line has slope $m'$ given by

$1 \cdot m' = -1$

and thus $m'=-1$

So, we want a line with slope -1 and passing through (12,-1). Using the fomula

$y-y_0=m(x-x_0)$

we get

$y-(-1)=-1(x-12) \iff y+1=-x+12 \iff y=-x+11$
