Andre’s equation is y = 5x + 100 and Elena’s is y = 20x + 10
Andre - 5x + 100 the x is how many weeks (6) so it’ll be 5(6) + 100 which is 30 + 100 = $130 in 6 weeks
Elena - 20x + 10 same thing x is how many weeks (6) as well so 20(6) + 10 which is 120 + 10 = $130 as well in 6 weeks so therefore, the answer is C.
Answer:
The sum of the given vectors is ![[0,1,2]+[0,0,-3]=[0,1,-1]](https://tex.z-dn.net/?f=%5B0%2C1%2C2%5D%2B%5B0%2C0%2C-3%5D%3D%5B0%2C1%2C-1%5D)
Step-by-step explanation:
For the given vectors (which are R³ vectors), the sum is simply the sum of each coordinate, if a general vector is written as
![[x,y,z]](https://tex.z-dn.net/?f=%5Bx%2Cy%2Cz%5D)
<u>the sum of two vector will be in each coordinate at a time</u>.
To illustrate geometrically the resulting vector in the space xyz
![[0,1,-1]](https://tex.z-dn.net/?f=%5B0%2C1%2C-1%5D)
<em>we can say that the first coordinate is on the x-axis, the sencond on the y-axis, and the third one on the z-axis</em>, so the illustration will be a <em>vector starting from the center of coordinates, and ending in the coordinates 0 of the x-axis, 1 of the y-axis, and -1 of the z-axis</em>. <u>Or, in a plane yz (where x=0), a vector from the origin to the point 1 in y-axis, and -1 in z-axis</u>.
Its the 3rd answer ok hope this helps
You’re answer would be D love!
