If m ABC = 80°, what is m DBC? Justify your reasoning.

0

Using the Angle Addition Postulate, 20+ m2DBC

11

DBC = 60° using the subtraction property of equality.

EE

Using the Angle Addition Postulate, 20 + 80

DBC. So, m DBC = 100° using the addition property of equality.

0

Using the addition property of equality, 20 + 80

0

Using the subtraction property of equality, 80

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
