Answer:
$13,200
Step-by-step explanation:
20*3=60*20=1200
40*6=240*20=4800
40*9=360*20=7200
1200+4800+7200=13200
A linear equation has the form:
Let's find a linear equation using the table, and let's check if it satisfy all the points:
so:
Let's check the other points:
Therefore, we can conclude it is a linear function.
Answer:
y = - 3x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation of line
10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
