Add 4 to both sides, then 0-p-3p=0, and sum the p's -4p = 0, then p=0, by dividing both sides by -4

The solution for p is 0.

-4-p-3p=-4
-4-4p=-4 Combine like terms
-4p=-4+(-4) Bring constants to one side and combine like terms.
-4p=0 Solution
p=0/-4 Simplify using the division property of equality

p=0

A store owner bought a painting for $120. She is selling it for $190. What is the percent markup on the painting

stiks02 [169]

Answer:

The markup percent on the painting is 58.3%

Step-by-step explanation:

Here, The Cost price of the painting = $120

The selling price of the painting = $190

Hence, the total profit on the painting = Cost Price - Selling price

or Profit = $190 - $120 = $70

Now, Markup % = (Gross Profit / cost) x 100

⇒Markup % = $\frac{70}{120} \times 100 = 58.3$

Hence, the markup percent on the painting is 58.3%

Find the focus for y=x^2+4x-7

padilas [110]

ANSWER

$(2,-10.75)$

EXPLANATION

The given function is

$y = {x}^{2} - 4x - 7$

We rewrite this function to obtain,

$(y + 11) = {( x- 2)}^{2}$

We now compare this function to

$(y - k) = 4p {( x- h)}^{2}$

We have

$4p = 1$

This implies that,

$p = \frac{1}{4}$

The vertex is (2,-11).

The focus is

$(2,-11+ \frac{1}{4} )$

$(2,- \frac{43}{4} )$

$(2,-10.75)$
