Answer:
y=3x+13
Step-by-step explanation:
y=mx+b
y=3x+b
so now we plug in the coordinates
1=3(-4)+b
1=-12+b
b=13
Ordered pairs are (x,y). The plugin of (7, -39) works because -39 +4 equals -35. Dividing this by -5 equals 7 (x).
Answer:
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
where, and , is called the argument of z, .
The given complex number is -5i.
It can be rewritten as
Here, a=0 and b=-5. lies in 4th quadrant.
So, the trigonometric form is
Answer:
It would be y = 2x+4
Step-by-step explanation:
This is because Isabella has started with 4 baked pies and is gaining additional pies with in amounts of 2 pies.
With this, 4 would be by itself and 2 would be attached to the variable x for the unknown amount of additional pies.
Lastly, you would have this all equaling y, as y is the total amount of pies.
