The given line segment's midpoint is  (3,-6)

Step-by-step explanation:

Step 1 :

Let A be the point (4,-2) and B be the point (2,-10)

We need to obtain the midpoint of AB

Let M (x,y) be the Midpoint.

Step 2 :

The x co-ordinate of a line segment's midpoint obtained by adding the x co-ordinate of its end point and dividing by 2.  

The y co-ordinate of a line segment's midpoint obtained by adding the y co-ordinate of its end point and dividing by 2.

So we have x = (4 + 2) ÷ 2 = 3

y = (-2 - 10) ÷ 2 = -6

Hence M = (3,-6)

Step 3 :

Answer :

The given line segment's midpoint is  (3,-6)

Write the equation of the line that passes through the following points.<br> (3, 1) (1,7)
Marina CMI [18]

Answer:

y=-3x+10

Step-by-step explanation:

Slope formula y2-y1/x2-x1

7-1/1-3

simplify

6/-2

simplify

-3

now plug -3 into y=mx+b

y=-3(x)+b

choose any point and plug it into the equation, I am using (3,1)

1=-3(3)+b

simplify

1=-9+b

add 9 to both sides

b=10

plug into slope-intercept form

y=-3x+10

The solution to the inequality 3x-3\leq -15\,\,or\,\,4x-1\geq 11 is x\leq -3\,\,or\,\,x\geq 4

The number line is shown in figure attached.

Step-by-step explanation:

We need to solve the inequality: 3x-3\leq -15\,\,or\,\,4x-1\geq 11

Solving the inequality:

3x-3\leq -15\,\,or\,\,4x-1\geq 11\\Adding\,\,3\,\,on\,\,both\,\,sides\,\,and\,\,1\,\,on\,\,both\,\,sides\\3x-3+3\leq -15+3\,\,or\,\,4x-1+1\geq 11+1\\3x\leq -12\,\,or\,\,4x\geq 12

Divide by 3 and divide by 12

x\leq \frac{-12}{3} \,\,or\,\,x\geq \frac{12}{4} \\x\leq -4\,\,or\,\,x\geq 3

So, value of x can be less than equal to -4 or value of x is greater than equal to 3.

The number line is shown in figure attached.

The solution to the inequality 3x-3\leq -15\,\,or\,\,4x-1\geq 11 is x\leq -3\,\,or\,\,x\geq 4

Tpy6a [65]
The best approach to this is to use the law of cosine which is stated as  
c2 = a2 + b2 â’ 2ab cos(C)
 distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value. 
 Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles
