What is the solution of the system of equations? y = 3x + 7
y = x - 9
1) (4, 19) because it satisfies one of the equations.
2) (4, 19) because it satisfies both of the equations.
3) (-8,-17) because it satisfies one of the equations.
4) (-8.-17) because it satisfies both of the equations.

its 50 miles away from the starting point

step-by-step explanation:

you divide them and then you get the answer i took this class this year

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
