Answer:
x=3 y=4
Step-by-step explanation:
x+y=7; x + 2y =11
step: solve x + y = 7 for x:
x + y+ -y =7 + -y (add -y to both sides)
x = -y + 7
step: substitute -y + 7 for x in x + 2y =11:
x + 2y = 11
-y + 7 + 2y = 11
y + 7 =11(simplify both sides of the equation)
y + 7 + -7 = 11 + -7 (add -7 to both sides)
y = 4
step: substitute 4 for y in x = -y + 7:
x = -y +7
x = -4 + 7
x = 3 (simplify both sides of the equation)
Answer: Focus = (-2, 3)
<u>Step-by-step explanation:</u>
First let's find the vertex. We do that by finding the Axis-Of-Symmetry:
Then finding the maximum by inputting x = -2 into the given equation:
The vertex is: (-2, 4)
Now let's find p, which is the distance from the vertex to the focus:
The vertex is (-2, 4) and p = -1
The focus is (-2, 4 + p) = (-2, 4 - 1) = (-2, 3)
