A suitable calculator finds the determinant to be ...
... B. -203
_____
This can be calculated by hand by copying the first two columns to the right of the given matrix, then forming the sum of products of the downward diagonals and subtracting the sum of products of the upward diagonals.
... (-4)(3)(-5) +(-4)(-5)(-5) +(-3)(3)(2) -(-5)(3)(-3) -(2)(-5)(-4) -(-5)(3)(-4)
... = 60 -100 -18 -45 -40 -60
... = -203
Answer: d
Step-by-step explanation:
Answer:
x = 3, y = -8
x = 4, y = -5
x = 5, y = -2
x = 6, y = 1
Step-by-step explanation:
You can apply the equation y = 3x - 17 for the different values for x.
x = 3
y = 3(3) - 17
= 9 - 17
= -8
x = 4
y = 3(4) - 17
= 12 - 17
= -5
x = 5
y = 3(5) - 17
= 15 - 17
= -2
x = 6
y = 3(6) - 17
= 18 - 17
= 1
Can you add detail? I'm not sure what to multiply in the form of fractions. Use x to space out the numbers.
Answer:
so that means you would divide 300 by 10 and that means she reads 30 pages in 1 hour so if you do 30 divided by 60 or 1 hour you get 0.5 pages so she reads 100 words in 1 minutes
