Answer:
a = 10
Step-by-step explanation:
Since the quantities vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the point (2, 5 ) with x = 2 and y = 5
k = = = 2.5
y = 2.5x ← equation of variation
Using the point (4, a) with x = 4, then
y = a = 2.5 × 4 = 10
The answer to that number pattern is 40,41,50,51
Answer:
Some possible values are -5, -3, -2.
Step-by-step explanation:
Basically if d(discriminant)
d > 0 = 2 x intercepts,
d = 0 means one x intercept
d < 0 = 0 x intercepts
:) Hoped this helped :)
Answer:
x-20
Step-by-step explanation:
x+4=y+24
x=y+24-4
x=y+20
y=x-20
