Answer:
true
Step-by-step explanation:
X^2 + y^2 = 8
X-y=0 so x = y
replace x = y into X^2 + y^2 = 8
y^2 + y^2 = 8
2y^2 = 8
y^2 = 8/2
y^2 = 4
y = - 2 and y = 2
because x = y
so x = - 2 and x = 2
solutions:
x= - 2 and x = + 2
y= - 2 and y = + 2

Answer:
1. X=-3, Y=0
2. all real numbers
Step-by-step explanation:
1.
2x+x+3=-6
3x+3=-6
3x=-9
x=-3
y=-3+3
y=0
2.
6x-2(3x-6)=12
6x-6x+12=12
0=0
All real numbers
Answer: 45 degrees I think.
Step-by-step explanation: Based off of looks alone, one could conclude that 3x is approximately 0.5 degrees larger than 2x, 2x is approximately 90 degrees, and that x is approximately half of 2x. so based purely off of observation, it appears that x is approximately 45 degrees. you can multiply x by the number by in it in each instance.
x=45, 2x=90, and 3x=135
