Step-by-step explanation:
The equation of a circle with radius and center is given by:
From this, we can find that the radius of the circle is and the center of the circle is at . Therefore, the coordinates of all points exactly 2 units away from this center point will lie on the circle.
Out of all options given, the desired answers are:
B. (5,5)
C. (3,3)

Answer:
x² - x - 6
Step-by-step explanation:
Given
(x + 2)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 3) + 2(x - 3) ← distribute parenthesis
= x² - 3x + 2x - 6 ← collect like terms
= x² - x - 6

A) Gavin’s drinks altogether cost £9.00
1.50+2.50x3
=1.50+7.50
=£9.00
b) Lian gets back £3.50
1.50+2.00+3.00
=6.50
10.00-6.50=£3.50
5. 53.96 - 19.99 = 33.97
33.97 / 53.96 = 0.629 = 63%
6. a 62% discount means she would pay 38% of the original price
2.15 * 0.38 = 0.82 . the 0.82 is not the discount, but the amount she would actually pay.
to check: the discount is 62% 2.15 x 0.62 = 1.33
2.15 - 1.33 = 0.82

7. A) the number of votes per vertical line is missing.
B) darken the vertical lines and total the number of colored squares there are then divide the number the winner got by total so 6/16 = 0.375 = 37.5% MAY NEED TO ROUND TO 38%
C) amber got 2/16 squares = 0.125. 420 * 0.125 = 52.5 = 53 votes
