Arc length = angle*radius
Degrees to radians: multiply by pi/180
Arc length = (pi/180*6)*6 = 36/180*pi = pi/5.
The answer is D.
Answer:
The x intercept = -9
The y intercept = -12
Step-by-step explanation:
To find the x intercept, set y = 0 and solve for x
-4x - 3y = 36
-4x -0 = 36
Divide by -4
-4x/-4 = 36/-4
x = -9
The x intercept = -9
To find the y intercept, set x = 0 and solve for y
-4x - 3y = 36
0 -3y = 36
Divide by -3
-3y/-3 = 36/-3
x = -12
The y intercept = -12
8v + 8b = 240
4v + b = 54....multiply by -2
-------------------
8v + 8b = 240
-8v - 2b = - 108 (result of multiplying by -2)
------------------add
6b = 132
b = 132/6
b = 22 <== buses hold 22 students
4v + b = 54
4v + 22 = 54
4v = 54 - 22
4v = 32
v = 32/4
v = 8 <== vans hold 8 students
Y + 8.3 = 12.7.....subtract 8.3 from both sides
y + 8.3 - 8.3 = 12.7 - 8.3...simplify
y = 4.4 <===
u can also check ur answer...
4.4 + 8.3 = 12.7
12.7 = 12.7 ...correct
