x-4>15.5
x>15.5+4
x>19.5
i suppose the answer is D since it is the closest to ^.
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
Answer:
x= -2, y = -3
Step-by-step explanation:
1. substitute x = 4+2y in the first equation: 
simplify it : 
2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->
3. solve for y: 5y = -15 --> y = -15/5 --> y= -3
4. solve for x: x = 4 + 2y
x = 4 + 2(-3)
x = 4 + (-6)
x = -2
Answer:
Your answer would be 60
Step-by-step explanation:
=36(6 - 4) 6(6 – 8)
= 36(2) + 6 (-2)
= 72 + (-12)
= 72 - 12
= 60
