Answer:
C
Step-by-step explanation: Since x is by itself in the first equation, we can substitute 12x + y = 5 into 12(6-y) + y = 5.
Answer:
is the correct representation of the graph.
Step-by-step explanation:
Firstly, if we look at the y-intercept, we can see that it is 25.
This means that we have narrowed down the options to the first and the second.
Next, our graph has a solid line. This means that we must have a 
sign.
This means that the inequality is the correct representation of the graph.
Answer:
The area of the circle is pi r^2,
and they substitute 3 for pi
and the radius is 6,
so we have 6^2 = 36 times 3
equals
108

Answer:
(1, 4 )
Step-by-step explanation:
- 9x + 4y = 7 → (1)
- 2x - 4y = - 18 → 2)
add (1) and (2) term by term to eliminate y
- 11x + 0 = - 11
- 11x = - 11 ( divide both sides by - 11 )
x = 1
substitute x = 1 into either of the 2 equations and solve for y
substituting into (1)
- 9(1) + 4y = 7
- 9 + 4y = 7 ( add 9 to both sides )
4y = 16 ( divide both sides by 4 )
y = 4
solution is (1, 4 )
