Answer:
1
Step-by-step explanation:
Choose two points on the line: (-5, 0) and (0, 5)
Let the first point 
= (-5, 0)
Let the second point 
= (0, 5)
Use the gradient formula:
----------------------------------------------------------------------------------------------------
If you want to find the equation of the line, use the point-gradient form of a linear equation: 
(where 
is the gradient and is a point on the line)
Substituting the values into the formula:
Therefore, the equation of the line is y = x + 5
Answer:
The student made the error at step 2.
Step-by-step explanation:
The correct step will be:
Step 2; 6x − 12 = 14 + 2x
As 3 will be multiplied with 2x and 4 which will give 6x − 12
Answer:
rectangle
Step-by-step explanation:
it would be a rectangle i believ. you can prove it by creating a coordinate plane and placing the points and then connecting the dots
I think that the median decreases, but not so sure.
Answer:
$2400 in A rated bond and $3000 in B rated bond.
Step-by-step explanation:
We have been given that Maria has recently retired and requested an extra $444.00 per year in income.
We can represent this information in an equation as:
She has $5400 to invest in an A-rated bond that pays 10% per annum or a B-rated bond paying 6% per annum.
From equation (1), we will get:
Substitute this value in equation (2):
Therefore, Maria should invest $2400 in A-rated bond.
Substitute in equation (1):
Therefore, Maria should invest $3000 in B-rated bond.
