Answer:
-3 + 5 = 2
-3 + -2 = 1
-2 + -1 = -3
5 - -1 = 6
Step-by-step explanation:
Answer:
It cost 30$
Step-by-step explanation:
Since 50% is 1/2 we put 80/2
so we have 40
25% is 1/4 we put 40/4=10 40-10=30
so the answer is 30
Answer: 2/3 left and 1/3 used
Answer:
m = -1/2 and b = 6.5
Step-by-step explanation:
To find the slope of the original line segment, we have to do the change in y/the change in x:
(4-8)/(-5--3) = -4/-2 = 2
2 is the slope of the original line segment, but since this is the perpendicular bisector, we have to take the negative reciprocal of 2 so m = -1/2
To find b we substitute the values of x, y, and m into the equation. Let's use the x value of -3 and the y value of 8:
y = mx + b
8 = -1/2(-3) + b
8 = 3/2 + b
6.5 = b
Y-intercept form is y=-3x+19, I’m not sure what you question is
