Answer:
4x + 8y = 50 or 4x + 8y > 50
Step-by-step explanation:
To find which equation show the exact answer, Becasue he need at least 50 poitns to have a B, so:
4x + 8y must larger or equal to 50
In these choice, some I can't figure out what it means but the correct answer for this is:
4x + 8y = 50 or 4x + 8y > 50
Hope this help you :3

<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)
Given:
f(x)= 2x+3 and g(x)= x²-5.
a) (f+ g)(3)
= f(3)+ g(3)
= 2(3)+3 + (3)²-5
=6+3+9-5
=13
b) (f-g)(4)
= f(4)- g(4)
= 2(4)+3 - (4)²+5
=8+3-16+5
= 0
c) (fg)(-2)
= f(-2)*g(-2)
=[ 2(-2)+3][(-2)² -5 ]
=(-1)(-1)
= 1
d) (g/f)(3)
= g(3)/f(3)
= 3²-5/ 2(3)+3
= 4/9
