Answer:
the orange line is the reflection y=-1
Step-by-step explanation:
(a^2+3b)/(c-2d)
substitute a=3,b=8,c=2,d=5
(3^2+3(8))/(2-2(5))
=(9+24)/(2-10)
=33/(-8)
=-4.125
Answer:
9x + 10y - (-x + 9y) (9x + 10y) + x -9y
Step-by-step explanation:
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>
