Answer:
The owner will have to pay $ 125 after 2 hours.
Step-by-step explanation:
Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :
((6000 - 5000) / 8) x 1 = X
(1000/8) x 1 = X
125 x 1 = X
125 = X
Therefore, the owner will have to pay $ 125 after 2 hours.
Answer:
900
Step-by-step explanation:
Answer:
Let's define all the possible forms:
slope-intercept: y = a*x + b
point-slope: y - y1 = a*(x - x1) (where (x1, y1) is a point in the line)
standard form: a*x + b*y = c
then:
a) 7x + 5y = 8
This is in standard form.
b) y − 5 = 3*(x − 9)
This is in point slope form.
c) y = 7x + 9
This is in slope-intercept form.
d) 8x − 9y = −2
This is in standard form.
Consider the given table.
- The first row represents first term (first brackets):
+x+x+x-1=3x-1
- The first column represents second term (second brackets):
+x-1=x-1
- The product of (3x-1) and (x-1) is equal to the sum of all remaining terms in this table:
+x²+x²+x²-x-x-x-x+1=3x²-4x+1.
Therefore, 3x²-4x+1=(3x-1)(x-1).
Answer: correct choice is C.
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 
m = 
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (r, - 4)
m = 
= 
, then equating gives
= ( cross- multiply )
3(r - 3) = - 12 ( divide both sides by 3 )
r - 3 = - 4 ( add 3 to both sides )
r = - 1 → B
