What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.
Answers
Answer:
-1/1
Step-by-step explanation:
The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.
(-2)-(0) / (0)-(-2) = -2 / 2

Problem 1: Over time, houses can sink slightly due to shifts in the soil below. One house was built with its ground at sea level, and over a period of 7 years, it sank to an elevation of -1 5/16 feet. How much change each year in elevation of house?
Answers
Answer:
-3/16 feet a year
Step-by-step explanation:
since we have a whole number 1 (5/16), we can turn this into an improper fraction 16(from the one) +5=21/16, since we know the number of years (7) we can divide 21 by the number of years. 21/7=3. So it went down 3 feet a year. Hope this helped!

Answer:
x= 72.72 (with a line over it)
Step-by-step explanation:
(x - 5) + (1.4x) + (x) + (x + 35) = 360
Step 1. Simplify both sides of the equation.
x + 5 + 1.4x + x + x + 36 = 360
(x + 1.4x + x + x) + (5 + 35) = 360 (combine like terms)
4.4x + 40 = 360
Step 2. Subtract 40 from both sides.
(4.4x + 40) - 40 = (360) - 40
4.4x = 320
Step 3. Divide both sides by 4.4
4.4x/4.4 = 320/4.4
x = 72.72 (72 repeats, so 72 with a line over it)

what's the real answer?
Step-by-step explanation:
The value of a= 17.5, b=-14 and c=-28.
What is function?A function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.
Given function:
f (x) = 3x – 1.
Also,
x f(x)
-5 a
-2 7
4 b
8 c
Now, using the proportionality
k = y/x
k = 7 / (-2)
k = -3.5
So, -3.5 = a/ (-5)
-3.5 x (-5) = a
a= 17.5
again, -3.5 = b/4
b= -14
Lastly, -3.5 = c/8
c= -28.
Hence, the value of a= 17.5, b=-14 and c=-28.
