Find the midpoint of the segment with the following endpoints (-3,-9)(-7,-3)
barxatty [35]

Answer:

(-5,-6)

Step-by-step explanation:

Let(-3,-9)=(x1,y1)

(-7,-3)=(x2,y2)

Using midpoint formula,

Midpoint(x,y)=((x1+x2)/2,(y1+y2)/2)

=((-3+(-7))/2,(-9+(-3))/2))

=((-3-7)/2),(-9-3)/2))

=((-10/2),(-12/2))

=(-5,-6)

Thus midpoint(x,y)=(-5,-6)

Log 15 = log(7 - 4x)​
Korvikt [17]

Answer:

x =-2

Step-by-step explanation:

log 15 = log(7 - 4x)​

The terms inside the log functions must be the same

15 = 7 -4x

Subtract 7 from each side

15-7 = 7-4x-7

8 = -4x

Divide  each side by -4

8/-4 =-4x/-4

-2 =x
