Answer:
Step-by-step explanation:
y-intercept is 4 and x-intercept is - 4
Answer:
y = -4
Step-by-step explanation:
- Plug the values into the slope formula.
y2 - y1 / x2 - x1
-4 - (-4) / 6 - (-8)
0 / 14
= 0
y = 0x + b
-4 = 0(6) + b
-4 = 0 + b
-4 = b
Answer:
The boiling point of water is between 84 °C and 88 °C when the elevation is between 3.4 and 4.6 km.
Step-by-step explanation:
You want x such that ...
84 ≤ B(x) ≤ 88
84 ≤ 100 -3.5x ≤ 88 . . . . substitute for B(x)
-16 ≤ -3.5x ≤ -12 . . . . . . . .subtract 100
4.6 ≥ x ≥ 3.4 . . . . . . . . . . .divide by -3.5; this reverses the inequality
