Answer:
y ≥ -2
Step-by-step explanation:
5y - 3 ≥ -13
+3 +3
5y ≥ -10
5/5y ≥ -10/5
y ≥ -2
and since we didn't divide by any negative numbers the sign stays the same
Answer:
y = (x - 1) / 2 (First answer choice)
Step-by-step explanation:
1) Start with f(x) = 2x + 1
2) Replace f(x) with y: y = 2x + 1
3) Interchange x and y: x = 2y + 1
4) Solve this result for y: 2y = x - 1, or y = (x - 1) / 2 (This matches the first
answer choice.)
Answer:
⇒ x = 3.4975
Step-by-step explanation:
Assume cost of each figure = x
Given:
32x + 2.32 = 114.24
Find:
Value of x
Computation:
⇒ 32x + 2.32 = 114.24
⇒ 32x = 114.24 - 2.32
⇒ 32x = 111.92
⇒ x = 111.92 / 32
⇒ x = 3.4975
