Answer:
m = -6
Step-by-step explanation:
2 (m + 7) = -4 - m
2m + 14 = -4 - m
3m + 14 = -4
3m = -18
m = -6

Probability of selecting 2 toys of different types
From the question, we understand that all toys are different i.e. 1 of each type.
And the selection is without replacement;
So, after the first toy is selected; there are n - 1 toys left.
So, the probability is:

Substitute 




Answer:
33
Step-by-step explanation:
The two angles add up to 180 degrees because a straight line is 180 degrees
<em>Add both equations and set equal to 180</em>
3m + 138 + 7m +12 = 180
<em>Algebra yeet</em>
<em>Simplify</em>
10m +150 = 180
10m = 30
m = 3
Angle DBC is (7m + 12):
<em>Substitute m = 3</em>
7(3) + 12 = 21 + 12 = 33 degrees
(0,5)(-10,0)
slope = (0 - 5) / (-10 - 0) = -5/-10 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur points (0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = 1/2(0) + b
5 = b
so ur equation is : y = 1/2x + 5
