Answer: -6
Step-by-step explanation:
9% = .09
.09-6.375 = −6.285
6.285 = 6.285/1 = 62.85/10 = 628.5/100 = 6285/1000
GCF = 5, 1257/200 = 6
-6
-6.285 = -6
The slope-intercept form: y = mx + b
We have the slope m = 9, therefore: y = 9x + b.
Next. We have the table:
x | -5 | -2 | 1 | 3 | 4 |
y |-46|-19| 8 |26|35|
(1, 8) → x = 1, y = 8
substitute the values of x and y to the equation:
8 = 9(1) + b
8 = 9 + b |-9
b = -1
Answer: y = 9x - 1 → y-intercept is -1.
t = 30a + 150 .
' t ' is the total cost of treatment.
' a ' is the number of appointments.
The $150 is paid only once.
I hope Pedro gets better fast. Poor little guy.
______________________________________
Oh, I see.
Now you're saying that she pays the $150 at every appointment.
So the equation is actually
<span>t = 180a</span>
