Answer:
x-intercepts (4,0) and (-2,0)
Step-by-step explanation:
f(x)=(x-4)(x+2)
f(x)=0=y
0=(x-4)(x+2)
x-4=0 or x+2=0
x=4 or x=-2
x-intercepts (4,0) and (-2,0)
Answer:
x = 15 hours
y = 25 hours
Step-by-step explanation:
Lets call "x" number of working hours of Clark family sprinklers
and " y " number of working hours of Thomas family sprinklers
Then they both worked in such way that
x + y = 40 (1)
On the other hand the total water output 1100 lts were supplied according to:
35 lts/h * y (hours) + 15 lts/h * x (hours) = 1100 lts
Then
35*y + 15*x = 1100 (2)
Equations 1 and 2 become a system of two equations with two uknown variables x and y
We solve that system
y = 40 - x and 35* ( 40 - x ) + 15* x = 1100
1400 - 35x + 15x = 1100 ⇒ - 20x = -300
x = 15 hours
And
y = 40 - 15 = 25 hours
