Hello :
<span>x²+2x+y²−4y+z²−8z=60
(x²+2x) + (y² - 4y) +(z² - 8z) = 60
(x²+2x+1) -1 +(y² - 4y +4 ) - 4 +( z² - 8z+16) -16 = 60
(x+1)² +(y-2)² +(z - 4)² = 9²
</span><span>the center is the point : A(-1, 2 , 4)
and radius : 9</span>
Ummm i think it is "if" because the "if" is the hypothesis and the then is the conclusion
Answer:
(-2, 6), (-7, 4), (-2, 4)
Step-by-step explanation:
by reflecting in the line y = 0, change all x coordinates to the opposite and y coordinates remain

Step-by-step answer:
1/8" long piece is not very much. However, mathematically,
we divide the total length by the length of each piece to get the number of pieces. So
4 2/5 / (1/8)
= (5*4+2)/5 * (8/1) [convert to fraction, and division to multiplication
= (22/5) * (8/1)
= 176/5
= 35 pieces with 1/5" left over.
10-3=7 so 10-7=3 so 7 dollars spent, 3 dollars left.
