Answer:
z=-8.7
Step-by-step explanation:
-0.3z=-17.4-2.3z
10(-0.3z)=10(-17.4-2.3z)
-3z=-174-23z
20z=-174
z=-8.7
Check:
-0.3z=-17.4-2.3z
-0.3(-8.7)=-17.4-2.3(-8.7)
2.61=-17.4+20.01
2.61=2.61
Answer:
no solution
Step-by-step explanation:
Given the 2 equations
y =
x + 4 → (1)
-
x + y = - 5 → (2)
Substitute y =
x + 4 into (2)
-
x +
x + 4 = - 5 , that is
4 = - 5 ← not possible
This indicates the system has no solution
Answer:
-1x-3
Step-by-step explanation:
-6x+5x=-1x
-10+7=-3
The correct answer is 3/2.
Slope = Rate Of Change
Slope Formula: y₂ - y₁ 5 - 2 3
-------------- = ---------- = -----
x₂ - x₁ 3 - 1 2
I hope that this helps you!
Btw, ₁ and ₂ are subscripts, they do not have anything to do with the actual working of the problem.
