Answer:
- ( -4, -1 ) and ( -9, - 6)
Step-by-step explanation:
<h3>Given</h3>
- (x - 1)^2 + (y + 3)^2 = 13
-
x + y = -3
<h3>Solution</h3>
<u>From the second equation we get</u>
<u>Substituting x in the first equation</u>
- (- y - 3 - 1)^2 + (y + 3)^2 = 13
- (-y - 4)^2 + (y + 3)^2 = 13
- (y+4)^2 + (y+3)^2 = 13
- y^2 + 8y + 16 + y^2 + 6y + 9 = 13
- 2y^2 + 14y + 12 = 0
- y^2 +7y +6 = 0
- (y+1)(y+6) = 0
- y = - 1
- y = - 6
<u>Then</u>
<u>Answer</u>
- ( -4, -1 ) and ( -9, - 6)
The answer would be 32,200 50*28*23
Step-by-step explanation:
((7²-2×7×3+3²)/8)-1=( 16/8)-1=2-1=1
If each game was 2.5 dollars then you would do 2.75 + 3.75 + 1.75 and get 8.25 dollars.
The answer is y<3. Hope this helps. (correct me if im wrong and sorry for the bad handwriting)
