If the matrix is of 2 by 2 then we can find the determinant of the matrix.
Then (ad - bc ) gives you the determinant of the matrix.
For example,
= (2)(-2) - (1)(4)
= - 4 - 4
= -8
Answer:
$214
Step-by-step explanation:
selling price= $107,000
subtract 10%down payment
107,000- (107,000*.1)
107,000-107,00
96,300
Interest rate= 8%
Annual payment= 96,300* 0.08
$7704
per month payment= 7704/12
$624
payment on closing only for 10 days
642*(10/30)
$214
Answer:
Let x represents the hours and y represents the total fees(in dollars)
As per the statement:
(a)
For a house call, a veterinarian charges $70, plus $40 an hour
"$40 an hour" means 40x
then;
the equation we get;
.....[1]
(b).
Find the x-intercept.
x-intercept states that the graph cross the x-axis.
Substitute y = 0 in the equation and solve for x;
we get;
y-intercept states that the graph crosses the y-axis i.e
Substitute x= 0 in the equation and solve for y;
Therefore, x-intercept and y-intercept of equation [1] are:
and 70
Answer: 180
