Answer:
Step-by-step explanation:
If the numbers all have the same surd (number under the square root), they can be added and subtracted as normal.
The theater department sold 102 tickets each night,because 2142÷ 3 nights = 714. 714 ÷ 7=102
Answer:
x = 0
y = 3
Explanation:
There are multiple ways to solve systems of equations. For this particular example, you can simply set them equal to each other because they are both equal to y and y = y, so therefore the equations equal each other.
so,
2x + 3 = -3x + 3
then solve for x!
add 3x to both sides: 5x + 3 = 3
subtract 3 from both sides: 5x = 0
divide by 5: x = 0
then to find y, plug the 0 back into either equation.
y = 2(0) + 3
y = 3
so, x = 0 and y = 3
i hope this helps!! :)
So the vertex formula is A(X - H)^2 + K so find the vertex and plug all numbers in
this gives you (x - 2.5)^2 -3.25 = f(x)
