X-intercept mean y=0
2/5x+1/10(0)=2
2/5x=2
X= 5
X-intercept = (5,0)
Y-intercept means x= 0
2/5(0)+1/10y=2
1/10y=2
y=20
Y-intercept = (0,20)
Answer:
in Alaska the temperature is always negative so that states the answer which is -2
With ellipse the equation to find c or the distance from the center to the foci is c^2 = a^2 - b^2. So if you plug those numbers in you get:
c^2 = 25 - 9
c^2 = 16
c = 4
The distance from the center to each foci is 4
44x-20=x+3
44x-x-20=3
43x=23
43x=3+20
x=23/43
You would take the number of pounds you want to buy (3.5) and multiply it by how much it costs per pound ($3.48).
It will look like this
(3.5)(3.48)
