Answer:
(0,−2)
Step-by-step explanation:
Answer:
(4,3)
Step-by-step explanation:
Given
x^2+y^2=25
x-y^2=-5
In order to solve the equations, from equation 2 we get
-y^2= -5-x
y^2=5+x
Putting the value of y^2 in equation 1
x^2+5+x=25
x^2+5-25+x=0
x^2+x-20=0
x^2+5x-4x-20= 0
x(x+5)-4(x+5)=0
(x+5)(x-4)=0
So
x+5=0 x-4=0
x=-5 x=4
Now for x=-5
x^2+y^2=25
(-5)^2+y^2=25
25+y^2=25
y^2=25-25
y^2=0
so Y=0
And for x = 4
x^2+y^2=25
(4)^2+y^2=25
16+y^2=25
y^2=25-16
y^2=9
y= ±3
So the solution to the system of equations is
(-5,0) , (4,3), (4,-3)
The only solution that belongs to first quadrant is (4,3)
Answer:
1/4x9=9/4 2 1/4, 2.25, (3/2)2
Step-by-step explanation:
The answer is 9/4 when you multiply it. But it can also be simplified as one of the answers here I wrote above.
Answer:
R = (c-a, b)
Step-by-step explanation:
You take the difference of the c-a because that's a rule of isoceles trapezoid.
R is on the same horizontal line as Q so the y coordinate is the same.
6 3/16
Multiply the 5 and 8 by 16 so they have common denominators.
