The solution is where the lines intersect.
So the one where the lines intersect at (4,-1) is the 2nd one
The fourth one, because that it intersects at point ( 4, -1)

Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.
2x + 25 + 25 = 180
2x = 130
x = 65
Answer:
Step-by-step explanation:
(5x+1)²>(2x+2)²+(4x)²
25x²+10x+1>4x²+8x+4+16x²
5x²+2x-3>0
5x²+5x-3x-3>0
5x(x+1)-3(x+1)>0
(x+1)(5x-3)>0
x+1=0,gives x=-1
5x-3=0,gives x=3/5
x >0(because 4x should be >0)
side is always positive.
so x>3/5
again 5x+1<2x+2+4x
5x-6x<2-1
-x<1
x>-1
x=all real values >3/5
Answer:
Sometimes true
Step-by-step explanation:
There is only one x value that satisfies the equation.
4x + 1 = 3
4x = 2
x = 1/2
2x - 6 < -10 ... (1)
6x + 10 > 28 ... (2)
• Step-by-step solution:
-> Equation 1
• Move -6 to right side
-> 2x < -10 + 6
-> 2x < -4
• Divide both sides by 2
-> 2x/2 < -4/2
-> x < -2 ... (1)
-> Equation 2
• Move 10 to right side
-> 6x > 28 - 10
-> 6x > 18
• Divide both sides by 6
-> 6x/6 > 18/6
-> x > 3 ... (2)
• Both equations
-> x < -2 ... (1)
-> x > 3 ... (2)
