The two lines intersect at (-3,4)
-2/3X+2= -2X-2
Add 2X to both sides
Subtract 2 from both sides
Divide both sides by 4/3
You get X=-3
Plug in 3 to one of the equations and you’ll see that y= 4
Answer:
31
Step-by-step explanation:
Increases by 7 each time
For sake of convenience, reverse the series, then it would be:
21,19,17.....7
a=21, d = -2,
s(4) = 4/2 (21+15)
s(4)=2(36)
s(4) = 72
4 cups = 18 g
Divide all by 4 to get 1 cup.
1 cup = 18/4
1 cup = 4.5g
Answer:
x^2 + y^2 = 49
Step-by-step explanation:
For center (h,k) and radius r, eqution of the respective circle is
(x-h)^2 + (y-k)^2 = r^2
