Step-by-step explanation:
X-2y=5 ; 2x-4y=10
• x - 2y = 5 • 2x -4y = 10
-2y = -x+5 -4y= -2x +10
y1 = ½x - 5/2 y2 = ½x -5/2
• => y1 = y2
½x -5/2 = ½x -5/2
the systems have no solution
• graph as attached
In C, denominator is x-3 and denominator should not be 0 . So we set x-3 to 0 and solve for x, that is
x-3=0
x=3
So domain can't be 3.
And if we see the equation, we will get the numerator and denominator both have same degree. So
Horizontal asymptote= numerator's leading coefficient /denominator's leading coefficient .
y= 2/1 =2
So at y=2, there is a horizontal asymptote , because of which y =2 is not a part of the range .
THerefore the correct option is C .
Multiply 75 by the number of surfboards sold to get 75x add that to what he makes giving lessons:
250 + 75x
He wants to earn at least 500 so the equation has to be greater than or equal to 500:
Answer: 250 + 75x > equal to 500
Step-by-step explanation:
-3/10x=1/2+7
=15/2
x=15/2×10/-3=-25
-25<1/2
Difference between they both was
1/2-(-25)
1/2+(25)
=51/2
=25.5
