"Write two equations: one parallel, one perpendicular to (5,-2) y= 1/5x-3
guajiro [1.7K]

Answer:

For parallel:

gradient is 1/5

y = mx + c

consider (5, -2):

- 2 = ( \frac{1}{5}  \times 5) + c \\  - 2 = 1 + c \\ c =  - 3

{ \boxed{ \bf{equation : y =  \frac{1}{5}x - 3 }}}

For perpendicular:

gradient, m1:

m _{1} \times m_{2} =  - 1 \\ m _{1} \times  \frac{1}{5}  =  - 1 \\  \\ m _{1} =  - 5

gradient = -5

y = mx + c \\  - 2 = (5 \times -  5) + c \\  - 2 =  - 25 + c \\ c =  23

{ \boxed{ \bf{equation :y =  - 5x + 23 }}}

Whats the difference between "6 + A" and "6 x A"
Nata [24]

Answer:

To determine what is the difference between "6 + A" and "6 x A", the logic of the proposed mathematical operations must be explained:

In "6 + A", the value A is added to the initial value 6. Thus, for example, if A were worth 10, to the initial value 6 10 units are added, with which the final value is 16.

In contrast, in "6 x A", the initial value 6 is multiplied by as many times as the value A indicates. Therefore, continuing with the value of A as 10, in this case 6 would be multiplied by 10 times, giving a final value of 60.
