6x^2 + 17x - 39 = 0
(3x + 13)(2x - 3) = 0
3x - 13 = 0 or 2x - 3 = 0
3x = 13 2x = 3
x = 4 1/3 x = 1 1/2

Solution: {1 1/2, 4 1/3}

5 is what percentage of 25? I’ll give brainliest:)

lord [1]

Hi there! :)

To solve, we can simply divide and multiply by 100 to solve for the percentage:

5 / 25 = 5 ÷ 25 = 1/5 or 0.20

Multiply the decimal by 100 to solve for the percentage:

0.20 × 100 = 20%

This hyperbola is centered at theorigin. Find its equation.Foci: (-2,0) and (2,0)Vertices: (-1,0) and (1,0)

beks73 [17]

SOLUTION

From the question, the center of the hyperbola is

$\begin{gathered} (h,k),\text{ which is } \\ (0,0) \end{gathered}$

a is the distance between the center to vertex, which is -1 or 1, and

c is the distance between the center to foci, which is -2 or 2.

b is given as

$\begin{gathered} b^2=c^2-a^2 \\ b^2=2^2-1^2 \\ b=\sqrt[]{3} \end{gathered}$

But equation of a hyperbola is given as

$\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1$

Substituting the values of a, b, h and k, we have

$\begin{gathered} \frac{(x-0)^2}{1^2}-\frac{(y-0)^2}{\sqrt[]{3}^2}=1 \\ \frac{x^2}{1}-\frac{y^2}{3}=1 \end{gathered}$

Hence the answer is

$\frac{x^2}{1}-\frac{y^2}{3}=1$

Three hikers are dividing the costs of a hiking trip evenly. They bought two permits that cost $15 each, three tram tickets that

cestrela7 [59]

Each hiker owes $41 or 4100 cents for the hiking trip.

<u><em>Explanation</em></u>

Cost of each permit is $15. So, the cost of <u>two permits</u> will be: $(\$15*2)= \$30$

Cost of each tram ticket is $19. So, the cost of <u>three tickets</u> will be: $(\$19*3)=\$ 57$

Cost of <u>one can</u> of bear spray is $36.

So, the total cost of the hiking trip $=\$30+\$57+\$36=\$123$

As the <u>three hikers</u> are dividing the total costs of the trip <u>evenly</u>, so each hiker owes $=\frac{\$123}{3}=\$41$ or 4100 cents.
