Answer:
A) True
Step-by-step explanation:
A basic variable is a variable that corresponds to a pivot column. A variable that does not corresponds to a pivot column is known as a free variable. It is required to row reduce the augmented matrix into echelon form so as to determine which of the variables are free and which of them are basic.
Answer:
1, 42
Step-by-step explanation:
Another pair of factors of 42 would be 2, 21. Factors, when multiplied, would get 42. 6,7 would also work, etc etc.
Answer:
40
Step-by-step explanation:
8/2 = 4
4 x 5 = 20
4 x 5 = 20
20+20 = 40
Y-y1=m(x-x1)
Y+5=7/3(x+3)
Y+5=7/3x+7 That one it's point-slope form
Y+5=7/3x+7
-5 -5
Y=7/3x+2 That one it's slope-intercept form.
0.41, 0.5, 3/5 is the order
