Answer:
The linear equation representing cost after using coupon is 
.
Step-by-step explanation:
Given:
Value of coupon = $18
Let the cost of the calculator be 'x'.
And the Cost after redeeming the coupon be 'y'.
We need to write a linear equation to represent using the coupon.
Solution:
Now we can say that;
Cost after redeeming the coupon will be equal to cost of the calculator minus Value of coupon.
framing in equation form we get;
Hence The linear equation representing cost after using coupon is .
The straight line distance is 5 miles from starting point.
Step-by-step explanation:
Driving 3 miles north and 4 miles east and then the straight line distance will form a right angled triangle.
Where;
One leg = a = 3 miles
Other leg = b = 4 miles
Hypotenuse = c
Using Pythagoras theorem;
Taking square root on both sides
The straight line distance is 5 miles from starting point.
The chemical structure includes the bonding angle, the type of bonds, the size of the molecule, and the interactions between molecules. Slight changes in the chemical structure can drastically affect the properties of the compound.
