Given:
The equation is:

It cuts the x-axis and y- axis at the point A and B respectively.
The area of ∆AOB =12 sq.units.
To find:
The value of <em>k</em>.
Solution:
We have,

Substituting
to find the y-intercept.




Substituting
to find the x-intercept.



Area of a triangle is:

The height of the ∆AOB is
because distance cannot be negative and the base of the ∆AOB is
. So, the area of the ∆AOB is:


It is given that, the area of ∆AOB = 12 sq.units.




Therefore, the value of k is either 24 or -24.
Answer: i have the answer to the first one good luck on your assignment!
Step-by-step explanation: 1. 12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25....what she paid for the fabric
she uses 2.5 yds of fabric for each dog bed.....12.5 / 2.5 = 5...so she can make 5 dog beds
each dog bed sells for 17.50.....5 * 17.50 = 87.50
87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25......so her total profit is $ 31.25 <==
His total savings was 55.00 and the end of June and .........................
whats the question
1. How much more iced tea did Pablo have than Rosa?
- = (40 × 4)/(9 × 4) - (41 × 3)/(12 × 3)
Pablo has 1 1/36 quarts of ice tea more than Rosa.
2. Pablo gave Rosa 15% of his iced tea today. How much iced tea do each of them have now? Write your answer in fraction form.
Iced tea given
- = 15% × 4 4/9
- = 15/100 × 40/9
- = 600/900
- = 2/3
Pablo iced tea
- = 40/9 - 2/3
- = 40/9 - (2 × 3)/(3×3)
- = 40/9 - 6/9
- = 34/9
- = 3 7/9
Rosa iced tea
- = 41/12 + 2/3
- = 41/12 + (2 × 4)/(3 × 4)
- = 41/12 + 8/12
- = 49/12
- = 4 1/12
Pablo has 3 7/9 quarts of iced tea and Rosa has 4 1/12 quarts.
