Answer:
<u>Given expression:</u>
<u>The first root is valid when:</u>
- 2x + 2 ≥ 0 ⇒ 2x ≥ - 2 ⇒ x ≥ - 1
<u>The second root is valid when:</u>
- 6 - 4x ≥ 0 ⇒ 4x ≤ 6 ⇒ x ≤ 1.5
<u>So the variable x can get values within interval:</u>
- -1 ≤ x ≤ 1.5 or
- x = [-1, 1.5]
Step-by-step explanation:
y = 4x+1
y–1 = 4x
x = (y–1)/4
Answer: 2nd place
Step-by-step explanation: you were in 3rd place and you passed the person in 2nd now making your placement 2nd and the other persons 3rd
Answer:
4
Step-by-step explanation:
y inversely proportional to x
y=1k/x
4=k/4
k=4×4
k=16
to find y
y=16/4
y=4
3m because in a square all sides are the same and there are 4 sides, so 12 ÷ 4 = 3
