Second answer box, try that
12A + 2 + A - 1 = a + 12a + 1 = 13a + 1
Answer:
Reciprocal of 5/18 is 18/5.
5/18 x 18/5 = 90/90
= 1
The answer is y=-3/2x +3 so D
Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
