Answer:
(-2, 1)
(2, 5)
Please solve the third question and answer in the comments and I will tell you if you are correct.
Step-by-step explanation:
1)Find the solution of the following system of equations; express the answer as a coordinate pair (x,y):
y = x + 3 subtract from the bottom and solve for x
y = -2x - 3
y - y = x - (-2x) + 3 - (-3)
0 = 3x + 6
-6 = 3x
-2 = x
y = x + 3 y = -2 + 3 y = 1 (-2, 1)
2)Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = 2x + 1 subtract from the bottom and solve for x
y = x/2 + 4
y-y = 2x - 1/2 x +1 - 4
0 = x(2-1/2) - 3
3 = 1.5x
2 = x y = 2x + 1 y = 2(2) + 1 y = 5 (2, 5)
3) Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = -3x + 6 subtract from the bottom and solve for x
y= -1/2x+1
y-y = x(-3 - (-1/2)) + (6 - 1) follow the examples above
Answer:
Add 1 to each side
Multiply each side by 4
Take the square root of each side
Subtract 5 from each side
Combine terms
Step-by-step explanation:
1/4(x+5)^2-1=3
Add 1 to each side
1/4(x+5)^2-1+1=3+1
1/4(x+5)^2=4
Multiply each side by 4
4*1/4(x+5)^2=4*4
(x+5)^2=16
Take the square root of each side
sqrt((x+5)^2)=±sqrt(16)
x+5 = ±4
Subtract 5 from each side
x+5-5 = -5 ±4
x = -5 ±4
Combine terms
x = -5+4 x = -5-4
x = -1 x = -9
