Answer:
Graph of solutions of:
y = x^2 -4 (red)
x + y + 2 = 0 (purple)
Step-by-step explanation:
Answer:
1000 times
First, we estimated the Sun's width in terms of the Earth's breadth, then the Star's width in terms of the Earth's breadth, and for comparison, we did simple division, which revealed that the Star KW Sagittarii is 1000 times wider than the Sun.
Answer:
5x+2y =-6 ........1
3x-2y = 22 ........2
Add both Equations
we get
8x = 16
Divide both sides by 8
x = 2
Substitute x = 2 into any of the equations
3(2) - 2y = 22
-2y = 22 - 6
- 2y = 18
Divide both sides by -2
y = - 9
x = 2 y = - 9
Hope this helps
The answer is C.
Explanation: There are 3 x variables and on the other side you see 11.
So the answer is 3x = 11
A=9,805×(1+0.085×7÷12)
A=10,291.16
