Answer:
-3
Step-by-step explanation:
Input -3 for x.
2*-3 - 9
then simplify.
Answer:
f=7/3
Step-by-step explanation:
from the figure it can be deduced that x=3 and
y=7
so: y=f(x) → 7=f(3)
put f to the first member: 7=3f → 3f=7 → f=7/3
(I hope that's right)
I am pretty sure that the answer is true
They're both 3 2/7 units away from 0, and so they have the same absolute value.
Absolute value is really just how far away a number from 0.
That's all I can really tell you.
<h2>
The area of the quadrilateral is
units.</h2>
Step-by-step explanation:
The given four sides of quadrilateral = (2, 4), (3, 5), (4, 6) and (5,8)
To find, the area of the quadrilateral = ?
We know that,
The area of quadrilateral ![=\dfrac{1}{2} [x_{1}( y_{2}-y_{3})+x_{2}( y_{3}-y_{4})+x_{3}( y_{4}-y_{1})+x_{4}( y_{1}-y_{2})]](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Bx_%7B1%7D%28%20y_%7B2%7D-y_%7B3%7D%29%2Bx_%7B2%7D%28%20y_%7B3%7D-y_%7B4%7D%29%2Bx_%7B3%7D%28%20y_%7B4%7D-y_%7B1%7D%29%2Bx_%7B4%7D%28%20y_%7B1%7D-y_%7B2%7D%29%5D)
![=\dfrac{1}{2} [2( 5-6)+3( 6-8)+4( 8-4)+5(4-5)]](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5B2%28%205-6%29%2B3%28%206-8%29%2B4%28%208-4%29%2B5%284-5%29%5D)
![=\dfrac{1}{2} [2(-1)+3(-2)+4(4)+5(-1)]](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5B2%28-1%29%2B3%28-2%29%2B4%284%29%2B5%28-1%29%5D)
![=\dfrac{1}{2} (-2-6+16-5)](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%28-2-6%2B16-5%29)
![=\dfrac{1}{2} (16-13)](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%2816-13%29)
=
units
Thus, the area of the quadrilateral is
units.
