Answer:

B(5, 7)

Step-by-step explanation:

Midpoint formula is given as

m(5, 7)= (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})  ------------(1)

Here

(x_1, y_1)=(3, 4)

Suppose point B is (x_2, y_2)

Substituting value sin equation (1)

(5, 7) = ( \frac{3+x_2}{2} , \frac {4+y_2} {2} )

5 =  \frac{3+x_2}{2} \\7 =   \frac {4+y_2} {2}

x_2 = 7

y_2 = 10

HELP PLEASE 3. Simplify the expression (5 points)<br> [(7 + 3) • 5 - 4] = 2 + 2
krok68 [10]

Answer: 46 or 46=4

Step-by-step explanation:

Do what's in the Parenthesis first so 7+2=10 which now give you the equation

[10x 5-4]=2+2

Now we Multiply so we do 10x5 which is 50 so that now gives us the equation[50-4]=2+2

Now we add the 2+2 which is 4 giving us the equation [50-4]=4

Now we subtract 50-4 giving 46

46=4

Write the equation of the line parallel to 2x - 6y = 12 that passes through the point ( -1, 4).​
vlada-n [284]

Answer:

y = 1/3x + 4 1/3

Step-by-step explanation:

2x - 6y = 12

First find the slope

Solve for y

Subtract 2x

2x - 6y -2x= 12-2x

-6y = -2x+12

Divide by -6

-6y/-6 =-2x/-6 +12/-6

y = 1/3 x -2

The slope is 1/3

Parallel lines have the same slope

Using the slope intercept form y = mx+b where m is the slope and b is the y intercept

y = 1/3x +b

And substituting in the point

4 = 1/3 (-1) +b

4 = -1/3 +b

Add 1/3 to each side

4 + 1/3 = b

y = 1/3x + 4 1/3
