Answer:
295 mi
Step-by-step explanation:
we can write this as an equation. the base fee, with no miles traveled is 25. this will be our y intercept, or b in the equation y = mx + b
our slope is .4
for every 1 mile increase for x, our y increases by .4
so:
y = .4x + 25
set this equal to 143.40
143.40 = .4x + 25
x = 295 mi
The factors of -18 are 1, 2, 3, 6, 9, 18 and their negative counterparts :)
"of" means to multiply.
20% * 60
= 0.2 * 60 (since % means divide by 100)
= 12
Step 1: Y= 27 - 4x
To find X - intercept / zero, substitute Y = 0
0 = 27 - 4x
Step 2: 0 = 27 - 4x
Move variable to the left-hand side and change it's sign.
4x = 27
Step 3: 4x = 27
divide both sides of the equation by 4
X = 27/4
solution: X = 27/4
Alternate form: X = 6 3/4, X = 6.75
