F(x)=2x(2)−96
Step 1: Add -4x to both sides.
xf+ −4x = 4x−96+ −4x
xf −4x= −96
Step 2: Factor out variable x.
x(f−4)= −96
Step 3: Divide both sides by f-4.
x(f−4)/ f−4 = −96/ f−4
x= −96/f−4
Answer:
x= −96/ f−4
Total cats: 8
Total expense: y
Expense per lion: $8,000
Total lions: z
Expense per leopard: $6,000
Total leopards: 8 - z
Therefore, the equation becomes:
total expense = number of lions × expense per lion + number of leopards ×expense per leopard
y = 8000z + 6000(8 - z)
y = 2000z + 48000
1/24 4 feet = 48 inches. 48 divided by 2 = 24. Therefore 48 divided by 1/24 = 2
Let
x--------------> ages of Raj
y--------------> age of Zia
we know that
x=y+3-------------> equation 1
x²+y²=369-----------> equation 2
<span>I substitute 1 in 2
</span>
(y+3)²+y²=369----------> y²+6y+9+y²=369---------> 2y²+6y-360=0
2y²+6y-360=0
using a graph tool-----------> to calculate the quadratic equation
see the attached figure
the solution is
y=12
x=y+3--------> x=12+3--------> x=15
the answer is
Raj is 15 years old
Zia is 12 years old
