Umm I think you divide a from b maybe
Answer:
each paid $2.45
Step-by-step explanation:
9.80/4 = 2.45
Answer:
(21, 2 )
Step-by-step explanation:
Given the 2 equations
y = -
x + 9 → (1)
y =
x - 12 → (2)
Substitute (2) into (1)
x - 12 = -
x + 9 ( add
x to both sides )
x - 12 = 9 ( add 12 to both sides )
x = 21
Substitute x = 21 into either of the 2 equations and evaluate for y
Substituting into (2)
y =
× 21 - 12 = 14 - 12 = 2
Solution is (21, 2 )
You mean coordinates?
They can be found out by substituting a number in the equation.
After substituting several numbers, we get:
x=4;y=5
x=-4;y=7
x=-2;y=7.5
