Answer:
det(A) = (-6)(-2) - (-4)(-7)
Step-by-step explanation:
The determinat of the following matrix:
Is given by: Determinant a*d - b*c
In this case, a=-6, b=-7, c=-4 and d=-2.
Therefore the determinant is: (-6)(-2) - (-7)(-4).
Therefore, the correct option is the third one:
det(A) = (-6)(-2) - (-4)(-7)
Answer:
10%
Step-by-step explanation:
40+5+5=50
50-5=45
45*2=90
50*2=100
100-90=10
Answer:√(6/5) and √(9/7) and √(7/5)
Step-by-step explanation:
1/4 = 0.25
5/4 = 1.25
√(6/5)=1.095445...
√(9/7)=1.1338934...
√(7/5)=1.1832159...
Thus, any non-perfect square radicals will be irrational numbers.
Hope this helps!! :)
Please let me know if you have any question
The slope of a line is rise/run. The formula is y=mx+b. But to find it on a graph you have to pin point 2 coordinate points. Doesn’t matter which ones they are. And then you have to put them in a y2-y1 over x2-x1 and that will give you slope.
I feel like #19 is cut off...
20. 72000000 = 7.2 x 10^7
if you do 72000000.0 and move the decimal to the left until the number is less than 10, it'll be 7 spaces.
