Answer:
6/5 hr, or 1 hr 12 min
Step-by-step explanation:
We're looking for the time required for two people to clear a field.
We'll end up with an expression that looks like:
1 job
------------ = time
rate
or
1 job
------------- this has dimensions of time (hr).
1 job/hr
specifically, we evaluate the following expression:
1 job
--------------------------------
1 job 1 job
-------- + --------
3 hr 2 hr
This simplifies to
1 1
-------------- = ----------- = 6/5 hr, or 1 hr 12 min
1/3 + 1/2 5/6

It is NOT a function.
<u>Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function</u>. <u>X = y2 would be a sideways parabola and therefore not a function.</u> Good test for function: Vertical Line test. If a vertical line passes through two points on the graph of a relation, it is <em>not </em>a function. A relation which is not a function. The x-intercept of a function is calculated by substituting the value of f(x) as zero. Similarly, the y-intercept of a function is calculated by substituting the value of x as zero. The slope of a linear function is calculated by rearranging the equation to its general form, f(x) = mx + c; where m is the slope.
A relation that is not a function
As we can see duplication in X-values with different y-values, then this relation is not a function.
A relation that is a function
As every value of X is different and is associated with only one value of y, this relation is a function.

Answer:
x=60 degrees
Step-by-step explanation:
All triangles equal to 180 degrees. 180-30=150-90=60
Answer:
x = 4
Step-by-step explanation:
Distribute parenthesis on both sides of the equation
4x + 4 = 6x - 4 ( subtract 6x from both sides )
- 2x + 4 = - 4 ( subtract 4 from both sides )
- 2x = - 8 ( divide both sides by - 2 )
x = 4
