The foci need to be equal distances from the center of the eclipse.

See the attached picture. I marked off all the points that were given as choice and from this you can see that that (-5,-4) and  (-5,2) are both 3 units away from the center.

The answer is: (-5,-4) and  (-5,2)

-4^-1 = 1/-4 = -1/4

-4^0 = 1

-4^1 = -4

-4^2 = 16

Given that f(x) = x² + 3x 28 and g(x) = x + 7, find f(x) + g(x) and
ozzi

Answer:

f(x) + g(x) = x^2 + 4x + 35

Step-by-step explanation:

Add like terms from f(x) and g(x):

f(x) + g(x) = x^2 + 3x + 28 + x + 7, or

f(x) + g(x) = x^2 + 4x + 35

3$ pre child 5$ adult totaling 374 tickets sold at the cost of 1524 dollars. how many child and adult tickets were sold
Elza [17]

Answer:

<em>173 children tickets were sold and 201 adult tickets were sold</em>

Step-by-step explanation:

Let the number of child ticket sold be x

Let the number of adult ticket sold be y

If the total number of ticket sold is 374, hence;

x +y = 374 .... 1

Also if the ticket cost 3$ per child and 5$ per adult with total cost of $1524, this can be expressed as;

3x + 5y = 1524..... 2

Solve both equations simultaneously

From 1; x = 374 - y ...3

Substitute equation 3 into 2

3(374-y)+5y = 1524

1122-3y+5y = 1524

1122+2y = 1524

2y = 1524 - 1122

2y = 402

y = 402/2

y = 201

Since x = 374-7

x = 374 - 201

x = 173

<em>Hence 173 children tickets were sold and 201 adult tickets were sold</em>

<em></em>
