Answer:

$y = -\frac{1}{2}x + 2$

Step-by-step explanation:

Assume this is function is a straight line, consider the equation of the straight line: $y=mx + c$

To find the gradient of the equation, we use any two coordinates from the table. $(x_1,y_1) = (6,-1)\\(x_2,y_2) =(2,1)$

$m = \frac{y_1 - y_2}{x_1 - x_2}\\\\m = \frac{1-(-1)}{2-6}\\\\m=\frac{2}{-4} \\\\m=- \frac{1}{2}$

We substitute the value of m in the equation:

$y =mx+c\\y = - \frac{1}{2} x + c\\\\$

To find c, we use the leftover coordinates, (4,0) in the equation above:

$y = -\frac{1}{2}x+c\\\\0 = -\frac{1}{2} \times 4+c\\\\0 = -2 + c\\\\c=2\\\\$

Substitute this value of c in the equation to get the function:

$y = -\frac{1}{2}x + 2$

Answer:

$\frac{3375}{512}$ or ≈6.59

Step-by-step explanation:

We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.

Take $25\frac{3}{2}$ for example. The '2' in the fraction means we must take the square of 25. √25 = 5.

The '3' in the fraction means we take the power, which means we must cube '5'.

5³ = 125. Therefore, $25\frac{3}{2}$ = 125. Use this process for the other numbers:

$25^{\frac{3}{2} } = 125\\243^{\frac{3}{5} } = 27\\16^{\frac{5}{4} } = 32\\ 8^{\frac{4}{3} } = 16$

The new fraction would look like:

$\frac{125 * 27}{32 * 16}$

Which simplifies to:

$\frac{3375}{512}$ or ≈6.59
