Then the original price was $42
Because it is half off we multiply 21 by 2 and get 42.
Answer:
Step-by-step explanation:
radius=4 as it is tangent to x-axis.
y co-ordinate of center is 4 so radius=4
eq. of circle is (x-2)²+(y-4)²=4²
or x²-4x+4+y²-8y+16=16
or x²+y²-4x-8y+4=0
If you mean where m=17 then the answer is 3 because 17-5 is 12 and 12/4 is 3.
Answer:
when (1.2) is substituted into the second equation the equation is true
Step-by-step explanation:
further you substitute x and the then solve
Answer:
y=.5x+-2.5
Step-by-step explanation:
This is the linear equation (y=mx+b) m means slope so your slope is .5.
