The slope would be 0 because if you put in the coordinates with the formula, you would get the slope as 0. This also makes sense because both points have the same y point, so that means that the line wasn’t travelling up or down. And since it was only going through -8 that would be the y-intercept.
9(k-2)=3(k-4)
We simplify the equation to the form, which is simple to understand
9(k-2)=3(k-4)
Reorder the terms in parentheses
+(+9k-18)=3*(k-4)
Remove unnecessary parentheses
+9k-18=+3+*(+k-4+)
Reorder the terms in parentheses
+9k-18=+(+3k-12)
Remove unnecessary parentheses
+9k-18=+3k-12
We move all terms containing k to the left and all other terms to the right.
+9k-3k=-12+18
We simplify left and right side of the equation.
+6k=+6
We divide both sides of the equation by 6 to get k.
k=1
Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
55 = k.5 → k=55/5 ; k =11
The value of z when = 12 is : z= kx; z = 11(12) and z = 132
Answer:
Step-by-step explanation:
Tools cost $1543
Interest = (Principal * rate * time)/100
Interest after 2 years = (1543*23.76*2)/100 = $733.23
The amount payable = $733.23 + $1,543 = $2,276.23
