Answer:
Step-by-step explanation:
you set the equation and try to bring it over one
i will do one of them for you
$9.40 for 5 cans of soup
to find what one can costs, divide 9.40 by 5
and you get $1.88
or you can set a proportion
9.40 x
--------- = ----------
5 1
cross multiple
5x=9.40
x=1.88
3x－15＝x＋3/3
9x－45＝x＋3
9x－x＝3＋45
8x＝48
x＝6
∠ABC＝3×6－15＝3°
∠DEF＝6＋3/3＝3°
Hope my answer helped u :)
Answer:
The equation relating the number of cars to the number of passengers is p = 4n
Step-by-step explanation:
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
The equation of the parabola is 
None of the given options is correct
Given:
Focus: (0, 3)
Directrix: y = -3
Note that:
f - k = k - (-3)
f - 3 = 3 + 3
f = 6 + 3
f = 9
The equation of the parabola is of the form:
Substitute f = 9, k = 3, h = 0 into the equation
The equation of the parabola is
