Answer:
20
Step-by-step explanation:
It's pretty much a function rule.
x=y/2 because 2.5*2=5.
So, you want to apply this rule to 10.
10=y/2
10=20/2
Hope this helps!

The equation for line ‘h’ is
h(x)=-3/2x+15/2
H(3)=-3/2(3)+15/2
h(3)=3
The independent variable is the year. The year is not affected by any other factors.
Answer:
a = p * q
b = p * s + q * r
c = r * s
Step-by-step explanation:
In the trinomial ax² + bx + c
a is the coefficient of x²
b is the coefficient of x
c is the numerical term
∵ The trinomial is ax² + bx + c
∵ Its factors are (px + r) and (qx + s)
∴ ax² + bx + c = (px + r)(qx + s)
∵ (px + r)(qx + s) = (px)(qx) + (px)(s) + r(qx) + (r)(s)
∴ (px + r)(qx + s) = pqx² + (psx + qrx) + rs
∴ ax² + bx + c = pqx² + (ps + qr)x + rs
→ By comparing the two sides
∵ ax² = pqx² ⇒ divide both sides by x²
∴ a = pq
∵ bx = (ps + qr)x ⇒ Divide both sides by x
∴ b = ps + qr
∴ c = rs
∴ a = p * q
∴ b = p * s + q * r
∴ c = r * s
This is the correct solution if I am not mistaken :)
