Answer:
X=5 (Or (5,0))
Step-by-step explanation:
The Y intercept is when X=0
The X Intercept is when Y=0
Our equation is y=-4200x+21000
So let's rewrite it... First subtract 21,000 (Also, remember Y is 0)
0-21000=-4200x
-21000=-4200x
Now to get X alone, divide -21000 by -4200
This will give us 5=x, which is the same as x=5. There is your answer!
Answer:
The solution set is {-3, -6}.
Step-by-step explanation:
x^2 + 18 = -9x
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.
Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.
