Answer:
triangle
Step-by-step explanation:
Step-by-step explanation:
the standard slope-intercept form is
y = ax + b
the factor of x (here "a") is always the slope of the line. b is the y-intercept (the y value when x = 0).
the slope of the other line is 5/6.
ok.
perpendicular to this means in a right angle (90°).
and that means that the fraction of "y coordinate change / x coordinate change" turns upside-down, and the sign has to flip.
so, the slope of our line is then -6/5.
and b ?
we use the given point.
1 = -6/5 × -9 + b = 54/5 + b
5/5 = 54/5 + b
b = -49/5
and our line equation is
y = (-6/5)x - 49/5
Answer:
B) 35
Step-by-step explanation:
42x25÷30=35
Answer:
≈ 1.8 km
Step-by-step explanation:
150*5= 750 revs total
d= 2.5 ft
C=πd= 2.5*3.14= 7.85 ft
Distance= 7.85*750= 5887.5 ft ≈ 1.8 km
Answer:
The last set cannot be the angles of a triangle
Step-by-step explanation: 61+61+59= 181. The angles of a triangle must always total 180°
All the other combinations meet that requirement.
