Answer:
Option A
|-6 -2|
|1 1|
Step-by-step explanation:
This is a product of a matrix.
So for the first number on the first row, we have;
(4 × -3) - (3 × -2) = -12 + 6 = -6
For the second number on the first row, we have;
(4 × 1) - (3 × 2) = 4 - 6 = -2
For the first number on the second row, we have;
(-1 × -3) - (-1 ×-2) = 3 - 2 = 1
For the second number on the second row, we have;
(-1 × 1) - (-1 × 2) = -1 + 2 = 1
Thus, we now have;
|-6 -2|
|1 1|
Answer:
slope: 5/7
0.714 mile per hour
Step-by-step explanation:
slope: find the point where the line is right on the line graph, put y/x which is 10/14 make the fraction smaller which is 10/14 = 5/7(I divide the denominator and nominator by 2)
Mile per hour: 5/7 cross multiply with x/1, make into an equation:
7x=5 x 1
7x = 5
x = 0.714
A - side of small map
a+6 - side of larger map
(a+6)² - area of larger map
(a+6)² = 121
(a+6)² = 11² |√(...)
a+6 = 11 |-6
a+6-6 = 11-6
