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)
Answer:
There are 5 terms in the series.
Step-by-step explanation:
Take logs to get n = 5
If the closing price on Thursday was 25.69...and the closing price on Wednesday went down -0.75.....then it went down -0.75 to get to 25.69.
so the closing price on Wednesday was : 25.69 + 0.75 = 26.44 <==
Answer:
y=4/3x-7
Step-by-step explanation:
Answer:
So 60% of this unknown number is 28
Let this unknown number be n
60/100 × n = 28
0.60 × n = 28
n = 28/0.6
n = 46.7
To the nearest wholw number is 47
So there are 47 votes in total
