Answer:
Or
Step-by-step explanation:
The slope formula is given by:
The line containing (2, 1) and (3, 4) has slope;
The point-slope form is given by:
We substitute the point and slope to get:
Or
In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:
Let x = be the total length
X = 4(112)
X = 448
Therefore,
34m + 1m + 212m = 247m
448m - 247m = 201 length of the fourth jump rope
Answer:
y = x
Step-by-step explanation:
Slope-intercept form is the form that looks like
... y = mx + b . . . . . . for slope m and y-intercept b
The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...
... y = 1·x + 0
... y = x . . . . . . without the identity elements
_____
<em>Comment on the marked choice</em>
The choice that is marked is the equation in <em>point-slope form</em> using the point E (4, 4). That is not the form requested by the problem.
Answer:
4 1/2 hours.
Step-by-step explanation:
If 1/2 an hour only used up 1/9 of her battery, 9, 1/2 would give us 9/2, which if you simplified it gets you 8 1/2 hours. Hope this helps! Have a great day!
