Answer:

B(1,0)

Step-by-step explanation:

The midpoint of (a,b) and (c,d) is ((a+c)/2,(c+d)/2)

Essentially, you just average the x and y values.

So, the average of -3 and b_x is -1.

The average of 4 and b_y is 2.

So x=1 and y=0

Which of the following equations is not a linear equation?

salantis [7]

Answer:

Step-by-step explanation:

All other equations have x or y to the power of one so they are linear. D. has x or y to the power of two, so it's not linear. Quadratics and any variable to the power of 2 and above is not linear (numbers on their own are also always linear, so ignore any powers on them)

Determine the median value.<br><br> 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Brrunno [24]

9.25, right? Because there's 10 numbers, the two middle numbers are 9.3/9.2. so when you add them up you get 18.5, then you divide it by 2 because there were only 2 numbers added, and I got 9.25

HELP!! What is the value of x??

nordsb [41]

Answer:

X = 41°

Step-by-step explanation:

<h3>Sum of interior Angles of a ∆ is 180°</h3>

$\angle1 + \angle2 + \angle3 = 180 \degree$

$Here \\ \angle1 = 105 \degree \\ \angle2 = ? \\ \angle3 = x$

$\angle4 = 146 \degree$

$here \: \angle2 + \angle4 = 180 \degree \\ \: (liner \: pair \: angle) degree\\ \angle2 + 146\degree = 180 \degree \\ \angle2 = 180 \degree - 146\degree \\ \angle2 = 34\degree$

$\angle1 + \angle2 + \angle3 = 180 \degree \\ 105\degree + 34\degree + x = 180\degree \\ 139\degree + x = 180\degree \\ x = 180\degree - 149\degree \\ x = 41\degree$
