Find an equation of the parabola that has the indicated vertex and whose graph passes through the given point
vichka [17]
Equation of a parabola with vertex at (2, -1) is
y = a(x - 2)^2 - 1

Using the given point: -3 = a(4 - 2)^2 - 1
-2 = a(2)^2
4a = -2
a = -1/2

Therefore, required equation is
y = -1/2(x - 2)^2 - 1
y = -1/2(x^2 - 4x + 4) - 1
y = -1/2x^2 + 2x - 2 - 1
y = -1/2x^2 + 2x - 3

Write an equality that represents eight less that three times a number is more than 22​
leonid [27]

Answer:

3x - 8 > 22

Step-by-step explanation:

" eight less" means to subract 8 form something.  If you had 10 apples and I took some so now you had 8 less apples, you'd have 10 - 8 = 2 apples

"three times a number" means 3x.  3 times some number.

The expression 3x - 8 means "8 less than 3 times a number"

"is" is math is a statement of equality, either an equals sign or an inequality needs to go here.

Our inequality is

3x - 8 > 22
