PLEASE HELP ME OUT I DONT GET THIS :(

Mathematics
1 answer:
svp [43]3 years ago
3 0

Answer:

A

Step-by-step explanation:

Take any two points on the line

(-4,0) and (0,-1) find the slope

slope= y2-y1/x2-x1

=\frac{-1-0}{0-(-4)}=\frac{-1}{0+4}=\frac{-1}{4}

y-y1 = m(x-x1)

y-0=\frac{-1}{4}[x-(-4)]\\\\y=\frac{-1}{4}(x+4)\\\\y=\frac{-1}{4}*x+4*\frac{-1}{4}\\\\y=\frac{-1}{4}x-1

Help me plz. I dont understand.
Ahat [919]
For this, you would use simultaneous equations.

w=walnuts
a=almonds

3w+6a=51
5w+4a=55

Find a way to make one of the unknowns equal. since we are trying to work out the price of a pound of walnuts, I am going to make a equal on each side to leave us with w. This leaves us with:

15w+12a=165
6w+12a=102

Then take them away to leave w:

9w=163

Then solve:

w=163/9
= 18.11111111...

Then round it to 2 decimal places as the measurement is currency.

So 1 pound of walnuts equals $18.11

I need help with this problem and would really appreiciate a short explanation too.<br> 15 PTS
inysia [295]

okay. the point has an x and y value. place them into the equation.

1=m(1)+b

m=slope, and theequation tells you that slope is 7.

1=7(1)+b

now you need to figure out what b is.

1=7(1)+b

^

1= 7 +b

-7 -7

---------------

-6=B

b is 6. now place it into the equation, replacing the x and y values back.

y=7x-6.

write 7 and 6 in the boxes (the negative for the six has already been provided)
