1/3 and 1/2 is the correct answer
Step-by-step explanation:
4x²-9
4x²+6x-6x-9
4x²+6x-6x-9
2x(2x+3)-3(2x+3)
2x(2x+3)-3(2x+3)
(2-3)(2x+3)
solution
(8x-3)(2x+3)
Answer:
(4,7)
Step-by-step explanation:
f(x)=5x-13
Let this equal to 7
7=5x-13
Add 13 to each side
7+13 = 5x-13+13
20 = 5x
Divide by 5
20/5 = 5x/5
4 =x
The ordered pair is
(4,7)
Cows(m) have 4 legs, chickens(c) have 2. Setting up a system of equations 104=4m+2c and 42=m+c. Solved for c the latter equation becomes 42-m=c. Using substitution in the first equation 104=4m+2(42-m). Distribute: 104=4m+84-2m. Combine like terms: 104=2m+84. Isolate variable term: 104-84=2m. Variable coefficient 1: 20/2=10=m. 42-10=32=c. <u>10 cows and 32 chickens.</u>
