The answer is
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-18, 13) and (-14, -20)
The slope is
We have the final answer as

Answer:
Below.
Step-by-step explanation:
7(x + 2) = 91
Distribute the 7 over the parentheses:
7x + 14 = 91
Subtract 14 from both sides of the equation:
7x = 91 - 14
7x = 77
x = 77/7 = 11.
Y = (x+3)^2 - 5 here's the answer hope it helps
Answer:
x-intercept: The plumber drained all the water out after 9 hours.
Relative maximum or minimum: The amount of water reached 70 liters before the draining began.
Increasing or decreasing interval: Over the first 5 hours, the leak just got bigger and bigger.
Step-by-step explanation:
W(t) is the amount of water in the basement. When W(t) = 0, there is no water in the basement. When W(t) = 0, W(t) is a x-intercept. So, x-intercept: The plumber drained all the water out after 9 hours.
The water level gets to a relative maximum after about 5 hours, when the water reaches about 70 liters. So, relative maximum or minimum: The amount of water reached 70 liters before the draining began.
The water level keeps increasing until the relative maximum. That is at 5 hours when the water level is 70 liters. After that point, the water level decreases as the water is being drained until the water level is 0 at 9 hours. So, the increasing or decreasing interval: Over the first 5 hours, the leak just got bigger and bigger.

Answer:
x = 3
y = -5
Step-by-step explanation:
5x+2y= 5 equation 1
3х - у = 14 equation 2
using equation 2 we have:
3x - 14 = y equation 3
using equation 3 in equation 1 we have:
5x + 2(3x -14) = 5
5x + 6x -28 = 5
11x = 5+28
11x = 33
x =33/11
x = 3
using equation 3 we have:
3(3) - 14 = y
y =9-14
y = -5
