Answer:

He would of saved 455$

Step-by-step explanation:

Because for 4 weeks he saved 35% of 200$ which would be 70 and 70+70+70+70 is 280$ and then he saved 175 dollars on the 5th week because 7/8 of 200 is 175 so 280+175= 455

Find the coordinates of the endpoint A given B (-3,5) is the midpoint of AC and C (1,-2)

WARRIOR [948]

coordinates of endpoint A are (-7,12)

Step-by-step explanation:

We are given midpoint B (x,y) =(-3,5)

One endpoint C (x₂,y₂)= (1,-2)

We need to find other endpoint A (x₁,y₁).

The formula to find midpoint is:

$x=\frac{x_{1}+x_{2}}{2}\\y=\frac{y_{1}+y_{2}}{2}$

We can find the coordinates of endpoint A using these formula.

We have x=-3, x₁=? and x₂= 1

Putting values and finding x₁

$x=\frac{x_{1}+x_{2}}{2}\\-3=\frac{x_{1}+1}{2}\\-6=x_{1}+1\\-6-1=x_{1}\\x_{1}=-7$

Now, y=5, y₁=? and y₂= -2

$y=\frac{y_{1}+y_{2}}{2}\\5=\frac{y_{1}+-2}{2}\\5*2=y_{1}+-2\\10=y_{1}+-2\\10+2=y_{1}\\y_{1}=12$

SO, coordinates of endpoint A are (-7,12)
