Which equation represents the perpendicular bisector of the given line segment?
In-s [12.5K]

Answer:

Option D. x=10

Step-by-step explanation:

step 1

Find the midpoint of the given line segment

we know that

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

we have

A(5,10),B(15,10)

substitute the values

M=(\frac{5+15}{2},\frac{10+10}{2})

M=(10,10)

step 2

Find the equation of the perpendicular bisector

we know that

The equation of a perpendicular bisector is equal to the x-coordinate of the midpoint, because is a vertical line (parallel to the y-axis)

therefore

the equation is equal to

x=10

What are the three differences between an inconsistent system and a consistent and independent system. Explan?
RUDIKE [14]
Hey there Mejia021274,
1) Independent systems have exactly one solution:
x + y = 1
x - y = 3
x = 2, y = -1

2) Inconsistent systems have no solutions :
5x + y = 6
5x + y = 10
There is no solution as 5x + y cannot be equal to 6 and 10

3) Consistent systems have a lot of solutions:
x+y = 5 
<span>2x+2y = 10 </span>
<span>A few solutions to this system are (1,4), (2,3), (3,2), (4,1), (5,0), and so on.
</span>
Hope this helps :))

The regression equation for predicting number of speeding tickets (Y) from information about driver age (X) is Y = -.065(X) + 5.
ivolga24 [154]

Answer:

c. 4.27

Step-by-step explanation:

We have been given the regression equation of for predicting number of speeding tickets (Y) from information about driver age (X) as Y=-0.065(X)+5.57.

To find the predicted number of tickets for a twenty-year-old, we will substitute X=20 in our given equation.

Y=-0.065(20)+5.57

Y=-1.3+5.57

Y=4.27

Therefore, the predicted number of tickets for a twenty-year-old would be 4.27 tickets.
