Answer:
D. 64 and 81
Step-by-step explanation:
The best benchmarks are the ones that are the closest to the value you want the root of. Perfect squares in that neighborhood are ...
- 7² = 49
- 8² = 64
- your number = 70
- 9² = 81
- 10² = 100
The closest are 64 and 81.
The answer to your question is 74/99:D
Given equations : Equation A: 4y -3x =16 and
Equation B: -x-8y =3.
We are given a point (-5,0.25) plugging it in first equation
4(0.25) -3(-5) =16
1+15 =16.
16 =16 : Satisfies first equation.
We are given a point (-5,0.25) plugging it in second equation.
-(-5)-8(0.25) =3.
5 - 2 = 3.
3=3.:
Therefore, they are the only values that make both eqautions true.
