2(x+3)=4x+1
2x+6=4x+1
-2x=-5
x=2.5
3x-4 = 6x-10
-4=6x-3x-10
-4=3x-10
-4+10=3x
3x=6
x=2
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
240 seconds, 60 times 4 is 480. there is 60 seconds in a minute, times that by 4.
ANSWER
5
EXPLANATION
We want to simplify:
when x=2.
We substitute x=2 into the absolute value expression to obtain:
The about value of 5 means what is the distance of 5 from zero on the real number line.
