3x+7=13 (x=-2;x=2;x=5)

AnnZ [28]

X=2 because 3 times 2 is 6 and then you add 6 and 7 together and get 13.

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

$x=10$

There are (4^9)5 ⋅ 4^0 books at the library. What is the total number of books at the library?

LenKa [72]

Your answer is B. You multiply 5 by the exponents and 4^0 is just 1, so 4^45•1=4^45. Hope this helped!
