The answer is 3/5.
Continue this pattern and you'll see that it follows this geometric sequence
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
Answer: $4.50
Step-by-step explanation:
125=21.50+23x
This is the equation to find this situation since 125 was given and it equals the left over and the spent money.
Subtract 21.50 from both sides first to be epic.
103.5=23x
Very cool! Divide both sides by 23 to get 4.5=x
Is your function y= { -x+8, if x<4 x, if x is greater than or=4? Cause if so then yes, your answer would be true then
Answer:
$38.40
Step-by-step explanation:
20% of $48 is 9.60
