9, 16, x which should be the right answer
So x=x
and y=pounds
when x=0, y=64
when x=1, y=63.1
to find slope, (y1-y2)/(x1-x2)=(64-63.1)/(0-1)=0.9/-1=-0.9=slope
y=-0.9x+b
subsitute
64=-0.9(0)+b
b=64
y=-0.9+64
so int 2001, x=11
y=-0.9(11)+64
y=-9.9+64
y=54.1
Answer:
b
Step-by-step explanation:
just supplementary
Answer:
y=9sin(theta)
Step-by-step explanation:
I'm assuming it's in degrees. The amplitude of the graph is 9, and so you multiply the base sine equation y=sin(theta) by nine. I don't see any shifts and the period remains at 2pi (360 degrees) so I don't think anything else is really needed.
<u><em>Answer:</em></u>
x = -31.5
<u><em>Explanation:</em></u>
We are given that the quotient of x and -1.5 is 21
<u>This means that:</u>

To get the value of x, we will multiply both sides of the equation by -1.5
<u>This means that:</u>

x = -31.5
<u>Note that</u> the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)
Hope this helps :)
