Answer:
It means that the both sides of the expression in the given equation must be/are congruent.
Hope this helps!
In the second one I'm pretty sure you just measure the length of the points.
Answer:
a. x > 0.2
Step-by-step explanation:
In either order, subtract the left-side constant and divide by the x-coefficient.
3x +2.4 > 3
3x > 0.6 . . . . . . subtract 2.4
x > 0.2 . . . . . . . divide by 3
__
or
x + 0.8 > 1 . . . . divide by 3
x > 0.2 . . . . . . . subtract 0.8
Answer:
See below ~
Step-by-step explanation:
Completing the square :
- 9y² - x - 18y + 10 = 0
- 9y² - 18y + 9 - 9 - x + 10 = 0
- <u>(3y - 3)² - x + 1 = 0</u>
<u></u>
Graph :
Total cost=variable cost+fixed cost
variable cost=1.25 times x or 1.25x
fixed cost=3
y=1.25x+3
f(x)=1.25x+3 is da rule
