The answer is QR HOPE THIS HELPS!!! XD
Answer:
The distance is equivalent to 800 rods and 2200 fathoms.
Step-by-step explanation:
Given:
The distance of the Kentucky Derby in furlongs is 20 furlongs.
Now, in order to convert the distance in rods and fathoms, we use the conversion factor for each.
We know that,
1 furlong = 40 rods.
Therefore, the conversion factor is 
So, 20 furlongs is equivalent to rods =
Therefore, 20 furlongs is equivalent to 800 rods.
Now, we also know that,
1 furlong = 110 fathoms
So, the conversion factor is 
So, 20 furlongs is equivalent to rods =
Therefore, 20 furlongs is equivalent to 2200 fathoms.
Answer:
the answer is b
Step-by-step explanation:
pls give me brainliest plsss i gave you answer
Slope intercept form is y = mx + b where m is the slope and b is the y-intercept.
Plugging those in we get:
y = - 5/2x + 1
x=31,y=−61
Put the equations in standard form and then use matrices to solve the system of equations.
5x+4y=1,3x−6y=2
Write the equations in matrix form.
(534−6)(xy)=(12)
Left multiply the equation by the inverse matrix of (534−6).
inverse((534−6))(534−6)(xy)=inverse((534−6))(12)
The product of a matrix and its inverse is the identity matrix.
(1001)(xy)=inverse((534−6))(12)
Multiply the matrices on the left hand side of the equal sign.
(xy)=inverse((534−6))(12)
For the 2×2 matrix (acbd), the inverse matrix is (ad−bcdad−bc−cad−bc−bad−bca), so the matrix equation can be rewritten as a matrix multiplication problem.
(xy)=(5(−6)−4×3−6−5(−6)−4×33−5(−6)−4×345(−6)−4×35)(12)
Do the arithmetic.
(xy)=(71141212−425)(12)
Multiply the matrices.
(xy)=(71+212×2141−425×2)
Do the arithmetic.
(xy)=(31−61)
Extract the matrix elements x and y.
x=31,y=−61
