Answer:
Step-by-step explanation:
y(x) and f(x) are similar in meaning; they both state that the dependent variable is a function of the independent variable x.
f(x) = 5x = y(x).
To find the x-int., let y = 0 and solve for x: 13x = 6, so x = 6/13: (6/13, 0)
To find the y-int., let x =0 and read off the y-int: (0, -6)

Answer:
Amrita = 14 years old
Aman = 6 years old
Step-by-step explanation:
Find out the difference of the units.
7 - 3 = 4
Amrita is 4 units/8 years older than Aman.
4 units = 8
1 unit = 8 ÷ 4 = 2
Amrita is 7 units and her brother is 3 units.
Amrita = 7 units x 2 = 14
Aman = 3 units x 2 = 6
Set the equation equal to zero.
9x+6=0
Subtract 6 from both sides
9x = -6
Divide both sides by 9
x=-6/9
or -2/3
2(5x-3)=0
Distribute
10x-6=0
add 6 to both sides
10x=6
Divide by 10 on both sides
x=6/10 or 4/5
5y+14=0
-14 from both sides
5y=-14
divide both sides by 5
y=-14/5
or -2 and 4/5
