Need help on question 4??

Anit [1.1K]

HK consists of two part, HJ and JK

HK = HJ + JK

We know that:

HK = 12.2ft

JK = 3.1ft

HJ = ?

Let's plug our values into the equation above.

12.2ft = HJ + 3.1ft

Subtract 3.1ft from both sides.

9.1ft = HJ

4(x-b)=x solve for x please thanks

Allushta [10]

4(x−b)=xStep 1: Add -x to both sides.−4b+4x+−x=x+−x−4b+3x=0Step 2: Add 4b to both sides.−4b+3x+4b=0+4b3x=4bStep 3: Divide both sides by 3.3x/3=4b/3x=4/3bAnswer:x=4/3b

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)
