Unicycle has 1 seat and 1 wheel.
Bicycle has 1 seat and 2 wheels.
u + b = 21
u + 2 b = 30 ⇒ u = 30 - 2 b
--------------------------------------
30 - 2 b + b = 21
30 - b = 21
b = 9, u = 30 - 18 = 12
There are 12 unicycles and 9 bicycles.
An equation in slope-intercept form:
u + b = 21
u = - b + 21
Answer: A ) u = - b + 21
31 1\4% as a fraction is 31x4+1 over 4
125\4 %
Domain is the x-values
Range is the y-values
To identify the range, plug in the x-values they gave you into the equation to find its y-value
x = 3
y = 2x + 4 Plug in 3 for x
y = 2(3) + 4
y = 10
x = 5
y = 2x + 4 Plug in 5 for x
y = 2(5) + 4
y = 10 + 4
y = 14
x = 6
y = 2x + 4 Plug in 6 for x
y = 2(6) + 4
y = 16
x = 8
y = 2x + 4 Plug in 8 for x
y = 2(8) + 4
y = 20
The range is {10, 14, 16, 20}
