Except x+12=5x-2
because:
4+12= 5*4-2
16=20-2
16=18 -- which is not true
he should know how much gallons he need to fill his car up
multiply 1.50 by the amount of gallons he need so he should know how much money to spend on that many gallons
hoped i helped and brainlist plz
Answer:
Step-by-step explanation:
Since our foci are located on the x-axis, then our major axis is going to be the horizontal transverse axis of the hyperbola:
<u>Formula for hyperbola with horizontal transverse axis centered at origin</u>
- <u />
- Directrices ->
- Foci ->
where 
Since we are given our directrices of 
and foci of 
, then we can set up the directrices equation to solve for 
:
Now we can determine 
to complete our equation for the hyperbola:
Therefore, our equation for our hyperbola is
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
