F(x) is the same as y.......so basically ur subbing in ur points into the equation to see if it comes out equal.

f(x) = 3 - 2x.....(-2,-1)....x = -2 and f(x) = -1
-1 = 3 - 2(-1)
-1 = 3 + 2
-1 = 5.....this is not true, so it is not a solution

and that is how to do this problem.....

(-1,5)......this IS a solution
(0,3)......this IS a solution
(1,0)...this IS NOT a solution
(2,-1)...this IS a solution

Find an equation of the line that satisfies the given conditions. Through (−3, −6), perpendicular to the line 2x + 5y + 8 = 0
Alexus [3.1K]

Answer:

Step-by-step explanation:

Using the point slope equation of a line to solve the question

y-y0=m(x-x0) where (x0,y0) is the point and m is the slope of the unknown line perpendicular to the given line.

Rewriting the equation given in the form y = MX+c

2x+5y+8 = 0

5y = -8-2x

y = -8/5-2x/5

From the equation, m = -2/5

Since the unknown line is perpendicular to the give line, the slope of the given line will be;

M = -1/(-2/5)

M = 5/2

Substituting the point and the slope into the equation above

y-(-6) = 5/2(x-(-3))

y+6 = 5/2(x+3)

y+6 = 5x/2+15/2

2y+12 = 5x+15

2y-5x = 15-12

2y-5x = 3 gives the required equation of the line

12w - 27 = - 34+14w Select the equation that has the same solution as the given equation above.
Lisa [10]
Anything with a value of w=3.5 would be equivalent.

To solve this, we cannot have a variable on both sides, so we will subtract 12w from both sides:
12w - 27 - 12w = -34 + 14w - 12w
-27 = -34 + 2w

Now add 34 to both sides:
-27+34 = -34 + 2w + 34
 7 = 2w

Divide both sides by 2:
7/2 = 2w/2
3.5 = w
