Answer:
Part 1: m = -7
Part 2: y = -7x -11
Part 3: 7x + y = -11
Step-by-step explanation:
Part 1
Select 2 points, in this case (-2, 3) and (-1, -4) and then use the slope formula
m = (y2 - y1) / (x2 - x1)
m = (-4 -3) / (-1 - -2) =
m = -7/1
m = -7
Part 2
Use the point-slope form equation to find the slope-intercept form
y - y1 = m(x - x1)
y - 3 = -7(x - -2)
y = -7(x +2) +3
y = -7x -14 +3
y = -7x -11
Part 3
Move the x and y to the same side of the equation
y = -7x -11
7x + y = -11
Answer:
x = 112
y = 76
Step-by-step explanation:
x + 68 = 180
x = 180 - 68
x = 112
y = 76 (Because of alternate interior angles)
Answer:
Multiply (400 + 20 + 3) x 10000
Add 4 zeros to the end of 423
Step-by-step explanation:
423 x 10,000 = Adding the amount of zero’s in 10000 to 423
Using the triangle similarity postulates, you can verify that
Answer:
A
Step-by-step explanation:
Pentagons have a total of 540°, so taking this into account, you need to add all of the angles together and then subtract 540 to get the missing angle.
90 + 90 + 140 + 140 = 460
540 - 460 = 80°
