Answer:
very easy
Step-by-step explanation:
4(2/3) = 14/3
14/3 ÷ 7
14/3 x 1/7
14/21
2/3
Well what is XZ. If XY is 4 & YZ is undefined. Is YZ undefined also? or does it have a given measurement?
The answer is D as it can be rewritten as -((y^2)/5)-(8/5)=x. Solving for the x-intercepts you get -((y^2)/5)-(8/5) = 0 as you want to find the y values when x is zero. Solving for y you get: (y^2)/5)+(8/5) = 0 => (y^2)/5)=-(8/5) => y^2=-8 => y = plus or minus sqrt(-8). The first problem is that you have 2 x intercepts which already makes it not a function and second sqrt(-8) is an imaginary number making the solution not a real number.
