Answer:
Step-by-step explanation:
a.
slope=-1/2
b.
eq. of line is
y-0=(-2-0)/(0-(-2)(x-(-2))
y=-2/2 (x+2)
or y=-x-2
You question implies simple subtraction is needed:
28-8=20
Answer:
W = 15 ft. and L = 30 ft.
Step-by-step explanation:
Perimeter = 90 ft.
Twice as long as it is wide: L=2W
P = 2(L + W) = 2(2W + W) = 6W
90 = 6W
W = 15 ft. and L = 30 ft.
Answer:
Yes, they are equivilant
Step-by-step explanation:
5(3m+2p)-4m = 13p+11m-3p
Distribute 5: 15m+10p-4m = 13p+11m-3p
Combine like terms: 15m+(-4m) = 11m ; 13p+(-3p) = 10p
11m+10p = 11m+10p
Answer:
Experiment
Step-by-step explanation:
Base on the scenario been described in the question, where Mrs. Reynolds has many (over a hundred) houseplants of many different types including philodendrons, ferns, spider plants, cacti, tomatoes, pineapples, this is a typical example of experiment .
An experiment is a procedure carried out to support, refute, or validate a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated
