For this case we must resolve the following expression:
We have to:
The base change rule can be used if a and b are greater than 1 and are not equal to x.
We substitute the values in the base change formula, using
Answer:
-4
Option A
1) slope=3 and y-int.=-5
2) slope=2 and y-int.=-6
3) slope=-6 and y-int.=1/2
4) slope=-7 and y-int.=5/2
5) slope=1/2 and y-int.=7
6) slope=3/4 and y-int.=8
7) slope=-2/3 and y-int.=-1/3
8) slope=-1/8 and y-int.=-3/8
9) slope=2/3 and y-int.=5
10) slope=-2/7 and y-int.=-1
11) slope=-3 and y-int.=6
12) slope=4 and y-int.=7
Hope this helps!
Y = 2x - 3 --------- (1)
y = 4x + 1--------- (2)
---------------------------------
Equation (2) - (1) :
---------------------------------
(y - y) = (4x + 1) - (2x - 3)
0 = 4x + 1 - 2x + 3 // remove brackets
0 = 2x + 4 // combine like terms
2x + 4 = 0 // switch sides
2x = -4 // take away 4 from both sides
x = -2 ------ sub into (1) // Divide by 2 on both sides
y = 2(-2) - 3 // Sub x = -2 into equation (1)
y = -4 - 3 // Remove bracket
y = -7 // Combine like terms
-----------------------------------
Answer: x = -2, y = -7
