Answer:

[tex] \huge \colorbox{red}{y = x + 3}[/tex]

Step-by-step explanation:

to understand thisyou need to know about:linear equationPEMDASgiven:b=3let's solve:

linear equation slope intercept form:

[tex]y = mx + b[/tex]

m is 1 in this question

therefore

substitute the value of m and b

y=x+3

Answer:

y = x + 3

Step-by-step explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3).  The y-intercept is also represented by (0, 3).  The graph also goes through (-3, 0).  The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3.  Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution.  In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

write 1/3 as a power with an integer base

Answers

Answer:

[tex]3^{-1}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]\frac{1}{a^{n} }[/tex] ⇔ [tex]a^{-n}[/tex]

Given

[tex]\frac{1}{3}[/tex] = [tex]\frac{1}{3^{1} }[/tex] = [tex]3^{-1}[/tex]

When the exponent is a fraction, you're looking for a root of the base. The root corresponds to the denominator of the fraction. For example, take "125 raised to the 1/3 power," or 125^1/3. The denominator of the fraction is 3, so you're looking for the 3rd root (or cube root) of 125
