Part A:
Expression: 21 = 8h + 179
Part B:
21 = 8h + 179
h = - 19
Move 179 to the other side by subtracting 179 from both sides.
21 - 179 = -158
-158 = 8h
Then, divide both sides by 8 to get the feet descended per hour.
-158/8 = -19
h = -19
Therefore, Luther and Nicole descend approximately 19 feet per hour.

awww tysm! ill try to help you! :) Step-by-step explanation:
Answer: x + 7y = 12
Explanation:
The question is: "I<span>ndicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"
</span>
1) The standard form of the equation of the line passing through two points is:
Ax + By = C
2) You can find the equation of al line given two points in a two stages process:
i) Find the slope:
slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7
ii) set the point slope equation:
y - y₁ = m [x - x₁]
y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)
⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7
⇒ x + 7y = 12

-6x <= 4x + 2
Subtract 4x from both sides
-10x <= 2
Divide -10 on both sides
Final Answer: x >= -1/5
