What is the vertex of Y equals X to the second power -4x-5​
Fed [463]

Answer:

vertex = (2, - 9 )

Step-by-step explanation:

Given a quadratic in standard form : ax² + bx + c : a ≠ 0

Then the x- coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

x² - 4x - 5 ← is in standard form

with a = 1, b = - 4, thus

x_{vertex} = - \frac{-4}{2} = 2

Substitute this value into the quadratic for corresponding value of y

(2)² - 4(2) - 5 = 4 - 8 - 5 = - 9

vertex = (2, - 9 )

Solve this problem on paper using all four steps. A girl scout troop sold cookies. If the girls sold 5 more boxes the second wee
Varvara68 [4.7K]
This is a problem where you should make an equation.
Let's say x is the first week. It would mean
First Week : x
Second Week : x + 5
Third Week : 2(x+5)
You need to add these up to make your equation. Your equation will look something like this :
x+x+5+2(x+5) = 431
Now you simplify.
2x+5+2x+10 = 431
4x+15 = 431
4x = 416
x = 104
That means they sold 104 Boxes in the First Week.
104+5=109
So they sold 109 Boxes the Second Week.
109 x 2 = 218
And they sold 218 Boxes the Third Week.

What is the final equation in standard form of m=-6/7, b=3 1/7
arlik [135]
<span>We are given the slope and the y-intercept.

m=-6/7, b=3 1/7

We use the slope-intercept form of the equation of the line to get an equation.

y = mx + b

y = -6/7x + 3 1/7

Now we need standard form.
The x- and y-terms must be on the left side, and we need integer coefficients.

y = -6/7x + 22/7

Multiply both sides by 7.

7y = -6x + 22

Add 5x to both sides.

6x + 7y = 22
