Answer:
A and C.
Step-by-step explanation:
to get rid of the square root & n, you would have to multiply it by n on both sides of the equation, giving you r^n=a.
also to get rid of the square root & n, you can also multiply both sides of a and r by the exponential fraction with n as the denominator:
![\sqrt[n]{a} =r \\(a)^\frac{1}{n} = r\\a\frac{1}{n} = r](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20%3Dr%20%5C%5C%28a%29%5E%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r%5C%5Ca%5Cfrac%7B1%7D%7Bn%7D%20%3D%20r)
8 x 3 = 24
24 + 3 = 27
27/8 is equivalent
If only the numerator or the denominator is negative then the whole fraction is negative.
Answer:
y = 5/2x + 3
Step-by-step explanation:
Given the point (0, 3) and the slope of 5/2, we can plug those values into the following slope-intercept form:
y = mx + b
where m = slope = 5/2
b = y-intercept (the point in the graph where it crosses the y-axis; it is also value of y when x = 0). The y-coordinate of the given point contains the y-intercept, (0, 3). Therefore, the y-intecept = 3.
Putting these factors together, we can write the following equation:
y = 5/2x + 3
