Answer:
b , d
Step-by-step explanation:
12x-5+85=128.......12x+80=128......12x+80-80=128-80....12x=48...... divide both sides by 12 to get x=4. Now most people do not complete solving for the missing value....12(4)-5=43 degrees
Answer:
associative property of addition !!
Step-by-step explanation:
this is because you are ASSOCIATING the two numbers together
think of it like this
in a trio friendship there could be two friends that are closer
the 8 and the 10 in the second half of the equation are closer
BUT in the first half the 3 and the 8 are closer too
hope that made sense lol
Answer:
sqrt(65)
Step-by-step explanation:
To find the distance between the two points
d = sqrt( (x2-x1)^2+ (y2-y1)^2)
= sqrt( (4-3)^2 +(1 - -7)^2)
= sqrt( 1^2 + (1+7)^2)
= sqrt( 1+8^2)
= sqrt(1+64)
sqrt(65)
Roughly something like this. The y intercept is at (0,1). The x intercept is at (-.5,0). Another point is at (1,3).
