Answer:
q#1 Option B.2 possible solution is correct option
Q#2 option c. 1 viable solution is correct option.
Step-by-step explanation:
Q#1
y=4+3x+45
as this is a quadratic solution
and we know that when we solve a quadratic equation then it gives two possible solutions
hence option b is the correct option
Q#2
option c is correct option when we solve an quadratic equation it gives two solution one is positive and other is negative as we know that income cannot be negative
hence only one viable solution exists when we solve this
y=4+3x+45 quadratic equation

Step-by-step explanation:
If the budget is $200 and he have 15 members then we have divide the two. 200 / 15 = $13.33 per shorts. 15x =< $200. x represents 13.33. So the solution represents the coach may spend up to $13.33 per pair of shorts. If it was even 1 cent more than $13.33 than he wouldn't have enough.So he can spend up to $13.33 or less per pair of shorts.
Answer:
158.76 cm²
Step-by-step explanation:
Quadrilateral ABCD is composed of 2 right triangles
Construct the line BD, then
Δ ABD and Δ BCD are the 2 right triangles.
The area (A) of a triangle is calculated using
A = 
bh ( b is the base and h the perpendicular height )
Δ ABD with b = 18 and h = 7.5
A = × 18 × 7.5 = 9 × 7.5 = 67.5 cm²
Δ BCD with b = 15.6 and h = 11.7
A = × 15.6 × 11.7 = 7.8 × 11.7 = 91.26 cm²
Thus
area of ABCD = 67.5 + 91.26 = 158.76 cm²

5.
the equation looks like:
((2x+1)+4)/((x)+4)= 5/3
then you do cross multiplication and get:
6x+3+12=5x+20
subtract 5x on each side. subrtract the 3 and 12 from the 20.
and you get your answer 5=x
