Answer:
t = 3c
Step-by-step explanation:
C is the cost of 1 cereal box. To show how many are being bought (3), simply multiply them together in the expression 3c. T is the total price so it is on its own side of the equation.
Please tell me if I am incorrect. Hope this helps!
<span>Re-arrange the equation 4y - 3x = 8 in the form y = mx + c<span>y = 3/4x +2</span></span>
The gradient is 3/4
Now we need to work out the gradient of the 2nd line. Remember that when 2 lines are perpendicular the product of their gradients is -1. Let's call the gradient of the second line m.
<span><span>3/4m = -1</span><span>m = -4/3</span></span>
In the question we are told that the line passes through the point (0, 2). This means that the line crosses the y axis at +2.
So the equation of the line that is perpendicular to 4y - 3x = 8 is y = - 4/3x + 2
Finding the gradient of a line between two points
To find the gradient of a line we need to know how many it goes up, for every one across.
Example
Find the gradient of the line joining (1,3) to (4,9).
As we go from (1,3) to (4,9) the y value increases by 6, and the x value increases by 3. So the line goes 6 up for 3 across. So this line has a gradient of 6/3 = 2.
Use this technique to answer the following question:
<span>QuestionLine A goes through the points (4, 9) and (1, 3). Find the perpendicular line through the point (2, 0).</span>
Answer:
number 1: i wont guve you the answee but its either A or C thats the hint because your subtracting becasue it says your losing 950 a year so the adding is not it so its not B neither D it has to be either A or C.
number 2: its A
number 3: u think its D im not sure because its either B or D but im pretty sire its D.
number 4: its D there yiu have it hope it helped.
Answer:
The answer is 14 because it's the opposite of -14
<span>Current
employee = 40 340
A year ago a company has 40 340 – 24% employee.
Simply subtract 24% of 40 340 from 40 340 to get the number of employees last
year
=> 24% = .24
=> 40 340 x 0.24
=> 9681.6
Now, let’s subtract this 24% from the total number of employees in the current
=> 40 340 – 9 681.6 or 9682
=> 30 658.4 or 30 658
The number of employee last year before it increased 24%</span>
