(x,y)
if x repeats with a differnt y then it is not a function
A. none of them repeat, it's a function
B. none of them repeat, it's a function
both of them are functions
I’m not entirely sure what the question is asking because of the first word but the second equation (y=-x + 3) satisfies the conditions.
Answer:
(-(23/3), -(11/3))
Step-by-step explanation:
x=y-4
2x-5y=3
=====
2x-5y=3
2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]
2y - 8 -5y = 3
-3y = 11
y = -(11/3)
y = -3 2/3
Use this in the 1st equation to find x:
x=y-4
x=-(11/3)-4
x = -(11/3)-(12/3)
x = -(23/3)
x = -7 2/3
See graph attached.
In a 30-60-90 degree triangle, the ratio of the side lengths is 1:√3:2
if the hypotenuse is h, the legs are h/2 and h/√3 respectively
the area is (1/2)(h/2)(√3h/2)=√3h²/8
Since this is a compound interest problem, you have to take note that the amount Catherine will get per year is not the same. It will increase per year since it is compounded. So first, we get the amount after one year. This will be 7000 x 0.04 which is 280 plus 7280. In the second year, she will get 7571 (7280 x 0.04 + 7280). In the third year, she will get 7874 (7571 x 0.04 + 7571). In the fourth year, she will get 8189 (7874 x 0.04 + 7874). And finally in the fifth year, she will get 8517 (8189 x 0.04 +8189). So after five years, she has 8517
