Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (3, 5) into the partial equation
5 = 6 + c ⇒ c = 5 - 6 = - 1
y = 2x - 1 ← equation of line
The first one is 64, the second 250, the third 520, and the fourth is 96
Answer:
Numbers are 8 and 12
Step-by-step explanation:
x=4+y
x+y=20
Solving both equations
4+y+y=20
2y=16
y=8
x=4+8=12
