What’s the endpoint if E is the midpoint of DF? F(5,8) E(4,3)

Mathematics

The coordinates of D would be (3, -2)

In order to find this, we need to know that the value of E's points will always be the average of D and F's points. This is because it is the midpoint. Therefore we can use the following formula.

Value of x

(D + F)/2 = E

(D + 5)/2 = 4

D + 5 = 8

D = 3

Then we can do the same for the y values

Value of y

(D + F)/2 = E

(D + 8)/2 = 3

D + 8 = 6

D = -2

The taxi costs $2.25 for the first mile plus 15cents for each additional tenth of a mile. For a 5.2 mile trip, Eric payed $10 an
Verizon [17]
2.25 for the first mile. That leaves 4.2 miles.

4 * 0.1 = 0.4

0.15 * 4 = $6.00

0.15 * 2 = 0.3

$6.30 + $2.25 = $8.55

$10.00 - $8.55 = $1.45

The driver's tip was $1.45.

What are the x- and y-intercepts for a line with one point at (2,1) and another at (6,3)?​
OverLord2011 [107]

Answer:

x - intercept = 0 and y - intercept = 0

Step-by-step explanation:

Using the two point slope intercept form, the formula is;

(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)

We are given the intercepts to be at

(2,1) and (6,3).

So, x1 = 2 and x2 = 6,while y1 = 1 and y2 = 3

Plugging into the equation, we have;

(y - 1)/(x - 2) = (3 - 1)/(6 - 2)

(y - 1)/(x - 2) = 2/4

(y - 1)/(x - 2) = 1/2

Cross multiply to get;

2(y - 1) = x - 2

2y - 2 = x - 2

2y = x

Now, the x intercept will occur at y = 0.

Thus,

2(0) = x

x = 0

Also, the y intercept occurs when x = 0.

So, 2y = 0

y = 0

x - intercept occurs at (0,0) and y - intercept occurs at (0,0)
