Answer:
2,5 and 2,7 I believe
Step-by-step explanation:
It should be 2,5 and 2,7
First set both equations equal to y
y = -1/2x + 3
y = 3x - 4
Then set these two equal because they both equal y
-1/2x + 3 = 3x + 4
Combine like terms and solve
7 = 3.5x
x = 2
y also = 2 when you plug it back in
Therefore, (2,2)
26, 37. Add by odds like 1,3,5,7,9,11
Answer: x=-2 y=13
2(-2)+1=-3 check
-2-2=-4 check
Step-by-step explanation:
Horner's method:
2 1 -3
1 -2 -4
delta = det(
2 1
1 -2) = 2×-2 - 1 = -5
x = det(
-3 1
-4 -2)/-5 = (-2×-3-1×-4)/-5 = -2
y = det(
2 -3
1 -4)/-5 = (-8+3)/-5 = 1
Or by elimination
x = 2y - 4 from adding 2y=2y to second eqn
2(2y-4)+y=-3 by substituting for x in first.
4y-8+y=-3
5y=8-3=5
y=1
x=2y-4=2-4=-2
Answer:
2587
Step-by-step explanation:
so 199 workers per factory with 13 factories it is 199 times 13 which equals 2587
