Answer:
its (B)
Step-by-step explanation:
Answer:
The values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
Step-by-step explanation:
Given equations are 
and 
to solve the given equations by elimination method :
Adding the given two equations (1) and (2) we get


_______________
4x=-4

Therefore x=-1
Now substitute the value x=-1 in equation(1) we get
(-1)+3y=9
3y=9+1

Therefore the values of x and y to the given equations are x=-1 and 
The solution is (-1,
)
<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1

Answer:
2950
Step-by-step explanation:
i just subtracted 3,000 with 50
Y > |x| + 5
<span>(0,5) when x = 0, y > 5 ...FALSE
</span>(1,7) when x = 1, y > 6 ...7>6...TRUE
(7,1) when x = 7, y > 12 ...FALSE
answer
<span>B.(1,7)</span>
