B is the general term of this progression.
Answer:
25
Step-by-step explanation:
25 - 10 = 15.
Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
-8 and 2 is one pair
another could be -4 and -2.
Answer:
4(x+2) = 4*x + 4*2 = 4x+8
3(a+2) = 3*a + 3*2 = 3a + 6
2(x+3) = 2*x + 2*3 = 2x +6
Hope this help you :3
