2x - y = 1
y = 2x -1
slope = 2
perpendicular slope = -1/2
y = mx + c
y = -1/2 + c
at point (3,2)
2 = -1/2 (3) + c
c = 2 + 3/2
c = 7/2
y = -1/2 x + 7/2
y + 1/2x = 7/2
2x - y = 1 ------------------- (1)
y + 1/2x = 7/2 -------------(2)
(1) + (2):
2x + 1/2x = 1 + 7/2
5/2 x = 9/2
5x = 9
x = 9/5 ---- sub into (1)
2x - y = 1
2(9/5) - y = 1
18/5 - y = 1
y = 18/5 - 1
y = 13/5
Ans: x = 9/5, y = 13/5
Rewrite the equation in term of x and y . F(x) = x-2)^2-4
Use the vertex form y=a (x-h)^2 +k to determine the values of a,h and k. A=1
H=2 k=-4 find the vertex 2,-4
For the GCF, you want to perform the title backwards.
Write Factors of the numbers, find the Common ones and then the Greatest of those.
*It is good to write the factors in pairs to ensure none are left out
18
1, 18, 2, 9, 3, 6
27
1, 27, 3, 9
36
1, 36, 2, 18, 3, 12, 4, 9, 6
The factors common in all are 1, 3, & 9
Now, from these numbers, select the greatest - 9
