Answer : 96

x – y = 16 --------> equation 1

\frac{1}{8} x +\frac{1}{2} y = 52

x is the higher grade and y is the lower grade

We solve the first equation for y

x - y = 16

-y = 16 -x ( divide each term by -1)

y = -16 + x

Now substitute y in second equation

\frac{1}{8} x +\frac{1}{2} ( -16 + x ) = 52

\frac{1}{8} x - 8 +   \frac{1}{2} x = 52

\frac{1}{8} x  +   \frac{1}{2} x - 8 = 52

Take common denominator to combine fractions

\frac{1}{8} x  +   \frac{4}{8} x  -8 = 52

\frac{5}{8} x - 8  = 52

Add 8 on both sides

\frac{5}{8} x   = 60

Multiply both sides by \frac{8}{5}

x = 96

We know x is the higher grade

96 is the higher grade of Jose’s two tests.

What is the value of f (x)=16^x when x=1/2 ? A. 2 B. 4 C. 8 D. 32
Cerrena [4.2K]

Answer:

B

Step-by-step explanation:

Using the rule of exponents

a^{\frac{m}{n} } ⇔ \sqrt[n]{a^{m} }

Given

f(x) = 16^{x}, then when x = \frac{1}{2}

f(\frac{1}{2} ) = 16^{\frac{1}{2} } = \sqrt[2]{16} = 4
