Answer:
y = x - 5
Step-by-step explanation:
Note that when x increases from zero (0) to 5, an increase of 5 units, y increases from -5 to 0, an increase of 5 units.
Thus, the slope of this line is m = rise / run = 5/5 = 1.
The y-intercept is clearly discernable and is (0, -5).
Thus, using the slope-intercept form of the equation of a straight line:
y = 1x - 5, or just y = x - 5.
Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
Answer:
$27000
Step-by-step explanation:
Using the given formula :
I = P × R ×T
I = 90000 × 10/100 × 3
I = $27000
Answer:
7(2 + y)
Step-by-step explanation:
2 more than y:
2 + y
Product... and 7
2 + y × 7
Simplify it.
7(2 + y)
