Answer:
--- Distributive property
Step-by-step explanation:
Given
Ferns = 4
Palms = 2
Lillies = 10
Shrubs = 8
Required
Show the total cost of plants as an expression
Shorten it using the distributive property
First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;
So, 4 Ferns = 4F
2 Palms = 2P
10 Lilies = 10L
8 Shrubs = 8S
Total Plants = Summation of the above parameters
The above expression represents the total plants bought;
Now, to apply the distributive property; we simply look for a common factor;
In this case, the common factor is 2;
So, becomes
10/16 = 5/8
An equivalent fraction is:
20/32
Answer:
A. 15
B. Point-slope: y - 325 = 15(x-0)
Slope-intercept: y = 15x + 325
Standard: y - 15x = 325
C. g(x) = 15x + 325
D. 505
Step-by-step explanation:
Part A. m = (y2-y1)/(x2-x1)
m = (400-325)/(5-0)
m = (75)/(5)
m = 15
Part B
Point-slope: y - 325 = 15(x-0)
Slope-intercept: y = 15x + 325
Standard: y - 15x = 325
Part C: g(x) = 15x + 325
Part D:
g(x) = 15(12) + 325
g(x) = 180 + 325
g(x) = 505
