Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x
Find the value of y
substitute the value of x in the equation A
so
therefore
The solution is the point (-2,-2)
Hello,
Let's suppose y'=y-3
and x'=x-5
Parabola become y'²=8x' whose focus is (8/4,0)=(2,0)
y=y'+3==>y=0+3=3
x=x'+5==>x=2+5=7
Focus is (7,3)
Rem for parabola y²=kx focus is (k/4,0)

How to round to the nearest tenth:
Whenever you want to round a number to a particular digit, look only at the digit immediately to its right. For example, if you want to round to the nearest tenth, look to the right of the tenths place: This would be the hundredths place digit. Then, if it is 5 or higher, you get to add one to the tenths digit. If it is 4 or lower, the tenths digit remains the same.
For example, 3.58 can be rounded to 3.6 because the hundredths place digit, 8 is greater than or equal to 5.
3.32 would be rounded to 3.3, because the hundredths place digit, 2, is less than 5.
Answer: 8 is 16% of 50
