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:
360 feets
Step-by-step explanation:
Given :
Scale : 1 inch = 12 feets
This means 1 inch on paper (model) represents 12 feets in real life
If the model height = 30 inches ;
The actual height of the Saturn V rocket will be :
1 inch = 12 feets
30 inch = x
x = (30 * 12)
x = 360 feets
Actual height = 360 feets
Answer:
depends
Step-by-step explanation:
You divide all the number by 5 to get you answer of 4 pears, 6 bananas, 8 peaches, and 10 oranges
The first step is:
- determine how far from the house is young equestrian at noon.
2 x 10 = 20 miles
15 t = 20 + 10 t
15 t - 10 t = 20
5 t = 20
t = 20 : 5
t = 4 hours
Answer: at 4:00 PM.
