Mathematics
1 answer:
Vlad1618 [11]4 years ago
6 0

Answer:

Option C is false

It is true that the square of both 10 and -10 is 100 but you can still obtain 100 by squaring 5\sqrt{4} so the third option is incorrect

Daniel and Sofia both solve this system of equations:
Evgesh-ka [11]

Answer:

Sofias solution is correct.

Step-by-step explanation:

First of all you do not need two sets of the same equation.


y=-1.5x + 5.7

y = 0.5x + 0.3


If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.

1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.

Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.
