Answer:
Step-by-step explanation:
(-3,1) (5,3)
= 0.25
Answer:
x + y = 4,000
0.1x + 0.04y = 352
Step-by-step explanation:
Product A represents x and product B represents y. The first equation is the total number of items the store owner buys. The second equation is cost per item for both products. The above system of equations can be used to determine how much product A and product B the store owner bought.
Answer:
19x+52=0
19x=-52
Step-by-step explanation:
add the x and move the 52
the area in square feet is 4400. (because to find the area of the rectangle you multiply the 2 side lengths, 100 and 80 which gives you 8000, then you find the area of the square, multiply 60 by 60 which is 3600, then you subtract the total area of the backyard by the area taken up by the garden, 8000-3600, which gives you your total of 4400.)
The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
