ruslelena [56]

Answer:

5 candles

Step-by-step explanation:

Enny is selling candles for $3 at a fund raiser

She starts selling $4 to help her make change

Therefore the number of candles x that will be sold to get $19 can be calculated as follows

3x + 4= 19

3x = 19-4

3x= 15

x = 15/3

x= 5

Hence 5 candles must be sold to get $19

What is the y-intercept of the equation of the line that is perpendicular to the line y =
Luda [366]

Answer:

y intercept =10

line y=-x+10

Step-by-step explanation:

Let y=mx+b is the required line.

<u>Slope of perpendicular lines :</u> If m_{1} and m_{2} be slope of two perpendicular lines. Them m_{1}\times m_{2}=-1

y=mx+b is perpendicular to y=x+10

the slope of y=x+10  is =1

m\times 1=-1\\m=-1

Hence eqn is y=-x+b

This equation passes through (15,-5)

-5=-15+b\\b=-5+15\\b=10

so the line is y=-x+10

<u>y-intercept :</u>

Substitute x=10

y=0+10\\y=10
