PLEASE HELP. !!!!!!!!!!

Umnica [9.8K]

Answer:

the last one bottom right

Step-by-step explanation:

well, did it in my head, but the idea is to calculate it out

(x-8)*(x-8)=50

is just

x²-16x+64=50

to get the 64 down to just 5, we need to subtract 59, on both sides, leaving us with -9 on the righthand side

B(4, 0) and c(10, 4) are the endpoints of a line segment. what is the midpoint m of that line segment? answer

Lilit [14]

The midpoint formula is $Midpoint: ( x_{m} , y_{m} )=( \frac{sum of x coordinates}{2} , \frac{sum of y coordinates}{2} )$

Therefore,
$x_{m}= \frac{4+10}{2} =7$
$y_{m}= \frac{0+4}{2} =2$

Answer: (7,2)
You could also plot the points and fold the paper so the points are on top of each other. Make a crease in the paper and when you open it the point where the crease intersects the segment is the midpoint.

What is the solution to the system of equations?<br> 5x – 4y = 6<br> –5x + 4y = –10

ss7ja [257]

Elimination Method:

5x - 4y = 6
-5x + 4y = -10

5x - 4y = 6
+ -5x + 4y = -10
————————-
0 = -4

This statement is false, so there is no solution to the system of equations.
