6 + 5x ≥ 21

By subtracting six from both sides you're left with 5x ≥ 15

Divide five from both sides to isolate the variable. hope it helped :)

If the coordinates of a point p(m-3 , -6) = p(-7 , -6), then find the value of m .

Serggg [28]

Answer:

$m =-4$

Step-by-step explanation:

Given

$p(m-3 , -6) = p(-7 , -6)$

Required

Find m

$p(m-3 , -6) = p(-7 , -6)$

By comparison:

$m-3 = -7$

Add 3 to both sides

$m = -7+3$

$m =-4$

ANTONII [103]

Answer:

x=2, y=1

Step-by-step explanation:

The left and right sides are equal

7x-2 = 5x+2

Subtract 5x from each side

7x -5x-2 = 5x-5x+2

2x-2 = 2

Add 2 to each side

2x -2+2 = 2+2

2x = 4

Divide by 2

2x/2 = 4/2

x =2

The top and the bottom are the same length

6x+y = 7x-1

6(2) +y = 7(2)-1

12 +y = 14-1

Subtract 12 from each side

12 +y-12 = 13-12

y = 1

Find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3.

sammy [17]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut point with the y axis.

By definition, if two straight lines are parallel then their slopes are equal. Thus, the slope of the line sought will be $m = 2.$

$y = 2x + b$

We substitute the given point to find b:

$2 = 2 (-1) + b\\2 = -2 + b\\2 + 2 = b\\b = 4$

Finally the line is:

$y = 2x + 4$

Answer:

$y = 2x + 4$
