Answer:</h2><h2>
The cost of ketchup bottle, x = 2.89</h2><h2>
The cost of mustard bottle, y = 1.59</h2>
Step-by-step explanation:
Let the ketchup be represented as x and mustard as y
Briana bought 3 bottles of ketchup and 2 bottles of mustard and for $11.85
3x + 2y = 11.85 ...(1)
Logan bought 2 bottles of ketchup and 5 bottles of mustard for $13.73.
2x + 5y = 13.73 ...(2)
Multiplying eq (1) by 2, we get
6x + 4y = 23.7 ...(3)
Multiplying eq (2) by 3, we get
6x + 15y = 41.19 ...(4)
Subtracting eq (3) from (4),
we get 11y = 17.49
y = 1.59, substitute it in eq(1), we get
x = 2.89
Therefore, the cost of ketchup bottle, x = 2.89
The cost of mustard bottle, y = 1.59
A=(1,2) and b=(2, - 1) . Find 4a - 3b
1st carry out the scalar multiplication 4a and -3b
4a =[4(1) , 4(2) ] = (4 , 8)
-3b = [-3(2) . -3(-1)] = (-6 , +3)
4a - 3b = [(4-6) , (8+3)] = (-2 , 11)
You know that it will be less than one, because the number is already less than one, and dividing will only make it smaller, so it will remain less than one.
The correct way of proving Pythagoras Theorem here is:
<span>4- to prove that the area of two smaller squares combined is equal to the large square
This is because Pythagoras theorem states that the sum of the square of the two smaller sides is equivalent to the square of the third side. The squares of the sides are represented as the area of the squares because the area of a square is obtained by multiplying a length by itself, or squaring it.
