C
Step-by-step explanation:
y》0.5x + 1.8
x = 4, y = 4.5
4.5》0.5(4) + 1.8
4.5》3.8 (true)
Answer:
32m^4 + 12m^3 = 4m^3(8m + 3) ---------->correct
40m^6 - 4 = 4(10m^6 - 1) ---------->correct
Step-by-step explanation:
32m^4 + 12m^3 = 4m^3(8m + 3) ---------->correct
40m^6 - 4 = 4(10m^6 - 1) ---------->correct
15m^3 - 6m = 3m(5m^2 - 2) , so it's not correct if answer : 3m(5m^2 - 6m)
6m^2 + 18m = 6m(m + 3) , so it's not correct if answer : 6m^2(1 + 3)
The 5-pound bag is better value.
The easiest way to compare and find out which is a better buy is to find out how much is being charged for 1-pound of food in each bag.
$12 is divided by 3 beacuse it's a 3-pound bag and we are aiming to find what 1-pound is equal to.
$12 ÷ 3 = $4
So the first bag charges $4 per pound of food.
Then use the same method for the 5-pound bag.
$14.25 ÷ 5 = $2.85
So the second charges $2.85 per pound of food.
So as we can see, the 5-pound bag is clearly better value. For each pound of food you are saving $1.15 in comparison to what you would be spending if you opted for the first bag.
Hope this helps!

Answer:
D. 
.
Step-by-step explanation:
Given:
We need to reduce 
by 
Solution:
To reduce the equation means we need to subtract the one equation from other.
First we will arrange the equation n proper format we get;
⇒ equation 1
Also Arranging other equation we get;
⇒ equation 2
Now we will subtract equation 2 from equation 1 we get;
Now Applying distributive property for the sign we get;
Now Arranging the like terms we get;
Hence the reduce form of the given equation is .
