ANSWER
EXPLANATION
To find the equation in point-slope form, use the formula,
The
is the slope of the line.
We can read from the graph that, the straight line passes through, the points
We can use these two points to find the slope of the line.
The slope can found using the formula,
This means that,
We now use one of the points, say
with the slope to find the equation of the line.
If you distribute the 4 on left hand side, the equation becomes
As you can see, this is an identity: the left and right hand side are identical.
This means that, no matter which value for x you choose, the equation will always hold: we're basically asking "for which x values something is equal to itself?" Well, obviously always.
So, this equation has infinite solutions, every single value for x you can think of is a solution of this equation.
Answer:
9.1
Step-by-step explanation:
Tangent 33=x/14
x=14*Tan 33
x=9.1(nearest tenth)
Average speed is the distance traveled by an object in total and divided by the amount of time an object covers the distance. The formula is -
Average speed = total distance traveled / total time taken
= 68km+64km / 2 hrs.+3hrs.
= 132km / 5hrs.
= 26.4km/hr.
Therefore, the train's average speed is 26.4km/hr.
