Answer:
y = 1/2x + 2
Step-by-step explanation:
for x=10, y=7
for x=20, y=12
for x=30, y=17
y = 1/2x + 2
Answer:
Call the number x and y. Then:
x - y = 45
and
x/y = 4, So x = 4y
Substitute 4y for x in the first equation:
4y - y = 45
3y = 45
y = 45/3 = 15
Substitute y = 15 in the first equation
x - 15 = 45
x = 45 + 15 = 60
So the two numbers are 60 and 15
