<span>1/(4p)(x-h)^2+k=0
</span><span>1/(4p)(x-h)^2 = -k

<span>k(4p)(x-h)^2+1=0
4kp (x^2 - 2xh + h^2) + 1 = 0
4kp x^2 - 8kph x + 4kph^2+1 = 0
D = (-8kph)^2 - 4(4kp)(4kph^2+1) = 64(kph)^2 - 64(kph)^2 - 16kp
D = -16kp < 0
SO discriminant is always less than 0

I believe 2 dollars and 50 cents
Answer:
<em>£</em><em>1</em><em>9</em>
Step-by-step explanation:
Cheryl = 7 + 5 = £12
this means ova and eva also have £12 at the end
EVA'S ORIGINAL AMOUNT : X -7 =12
X = £19
The answer will be 12+13 because the skatepark is 12km from school and her favorite game store was 13 km so it’s 12+13=25km
Answer:
50 hammers and 20 wrenches.
Step-by-step explanation:
Let x represent number of hammers and y represent number of ranchers.
We have been given that a store sold 70 hammers and ranchers. We can represent this information in an equation as:

We are also told that each hammer sold for $10 and each rancher sold for five dollars resulting a total of 600.00. We can represent this information in an equation as:

From equation (1), we will get:

Substituting this value in equation (2), we will get:






Therefore, 20 wrenches were sold.
Now, we will substitute
in equation (1) as:



Therefore, 50 hammers were sold.
