The answer is (-4, 5) x= -4 y= 5
Simplification = 3.5x + 2.5x
Result = 6x
Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:
![a^{\frac{b}{c}}=\sqrt[c]{a^b}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%5Csqrt%5Bc%5D%7Ba%5Eb%7D)
So, you have
And similarly,
![81^{\frac{7}{4}}=\sqrt[4]{25^7}=\sqrt[4]{(3^4)^7}=3^7](https://tex.z-dn.net/?f=81%5E%7B%5Cfrac%7B7%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7B25%5E7%7D%3D%5Csqrt%5B4%5D%7B%283%5E4%29%5E7%7D%3D3%5E7)
Answer: <em>y = 3/4 x + 8</em>
Step-by-step explanation: First you must find the slope of line k.
<em>y2 - y1</em>
<em>m = -----------</em> <em>The slope is 3/4</em>
<em> </em><em>x2 - x1</em>
Since the two lines are paralell you know that line h has the same slope.
Next you must find the y-intercept by replacing x and y with the values given by the point.
<em>y = 3/4x + ? -----> 12 = 3/4(4) + ?</em>
<em> 12 = 3 + 8</em>
The y-intercept is 8
Your equation for line h is <em> </em><em>y = 3/4 x +8 </em>
