Answer:
The relationship between two variables is decreasing and linear.
Step-by-step explanation:
From the given table it is notice that the function passing through the points (1,5), (2,-1), (3,-7) and (4,-13).
Slope of the function between first two points (1,5) and (2,-1) is
Slope of the function between last two points (3,-7) and (4,-13) is
The rate of change or slope of the function is constant.
From the given table it is noticed that the values of y decreased by 6 units as the values of x increased by 1 units.
Since the rate of change constant and negative, therefore the relationship between two variables is decreasing and linear.
Answer:
The system will be inconsistent.
Step-by-step explanation:
We are given that a system of linear equations has a 3×5 augmented matrix whose fifth column is a pivot column.
Then such a system is not consistent because since the augmented matrix has a pivot in fifth column it means that the new column added to the matrix A will lead to increase in the rank as that of matrix A.
Hence the rank of A and Augment A will not remain same and hence the system will be inconsistent.
Answer:
36
Step-by-step explanation:
Sean purchased a printer and laptop
He sold both for 1,500
He sold the laptop at 1,350
Therefore the cost of the printer can be calculated as follows
1500-1350
= 150
24/100×150
= 0.24×150
= 36
Henve the cost of the printer is £36
Answer:
$2560
Step-by-step explanation:
if 10%=256
then 10 times the amount 100% is 2560
First we are going to find divided by 100 and multiply 20 is equal to four.
We are gonna use x to represent this number.
x/100 * 20 = 4
Solve for x
Therefore x = 20cm
Now that we found x the side of the larger square we are gonna find the area which is side^2.
20 * 20
Therefore the area of the larger square is 400cm^2
