What is the equation of the line which
1 answer:
Answer:
The equation of the line is y = (-1/2)x + 5
Step-by-step explanation:
First of all, have to find gradient using the formula above :
(2,4) & (14,-2)
m = (-2-4) / (14-2)
= -6 / 12
= -1/2
Second, using y = mx + b as b is a constant and is a y-intercept. Using any of these 2 coordinates to find the value of b with given gradient :
y = mx + b
Let y=4 & x=2
4 = (-1/2)(2) + b
b = 4 + 1
= 5
Lastly, put the value of gradient and y-intercept into the equation :
y = mx + b
Let m=-1/2 & b=5
y = (-1/2)x + 5

Answer:
The Inequality with integer coefficient for the total sales is
Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.
Step-by-step explanation:
Given:
Amount paid per week = 50
Addition amount = 3% of Total sales.
Let the Total sales be 'x'.
∴ Additional amount =
Amount he wants to earn this week 100
We need to write the inequality with integer coefficient for the total sales and also to find the total sales.
Solution:
We cans say that;
Amount paid per week plus Additional amount should be greater than or equal to Amount he wants to earn this week.
framing in equation form we get;
Now we will make the denominator common using LCM we get;
Multiplying both side by 100 we get;
Hence The Inequality with integer coefficient for the total sales is
On solving the above equation we get;
Subtracting both side by 5000 we get;
Dividing both side by 3 we get;
Hence Jonathan should make total sales of at least <u>1667</u> to earn at least 100.
