Slope=-9/12 = -3/4
y=mx+b y=-3/4x+b
3=-3/4(-6)+b
b=3+9/2=7.5
Equation is y=-0.75x+7.5
It's transilation (if that's how you spell it)
Step-by-step explanation:
let the num be 3x & 4x
3x+4x=28
7x=28
x=28/7
x=4
now, num of girls=3x=3×4=12
& num of boys=4x=4×4=16
When rates<span> are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called </span>unit rates<span>. To determine the rate, we just divide the distance traveled by the time it takes. Therefore, the rate of the plane would be
rate = 256 / 30(1/60) = 512 miles per hour</span>
