Answer:
12 > x ÷ (-5) ---------> x> -60
Step-by-step explanation:
1) Rewrite.
12> -x ÷ 5
12> -1/5x
2) Multiply both sides by -5 and flip the inequality sign.
12 × -5= -60
-60 < x
3) Swap the sides.
x> -60

Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
Answer:
BC = 11,5 (to the nearest tenth)
Step-by-step explanation:
BC^2 = AC^2 + AB^2
BC^2 = 13^2 + 6^2
BC^2 = 169 - 36
BC^2 = 133
BC = 11,5 (to the nearest tenth)
