4x + y = 18
(6, 3)
(3, 6)
(−3, 6)
(3, −6)
Answer:
(3,6)
Step-by-step explanation:
We can substitute y for x+3 in the second equation
4x + x + 3 = 18
5x = 15
x=3
Plug x back into the equation
y = 3 + 3
y = 6
Answer:
B (3 ; 6)
Step-by-step explanation:
y = x + 3
4x + y = 18
4x + (x + 3) = 18
5x = 18 - 3
5x = 15
x = 3
y = x + 3
y = 3 + 3
y = 6
What is -8.6 divide (-3)
it would be 8 + 16 =8 (1 + 2) because
the GCF is 8 so,
8 (1) + 8 (2)
which would equal to :
8 + 16 = 8 (1 + 2)
Answer:
○
Step-by-step explanation:
Use the zero-interval test[test point (0, 0)] to verify them as false or true, and to determine whether we shade the shared opposite portions [a shared portion that does NOT contain the origin] or the shared portions that DO contain the origin:
☑
☑
So, this system will be shaded in a shared portion containing the origin.
