You still want at most 

(15x) + (22y) ≤ 100(-z)           (equation used)

0 ≤ z ≤ 10                              (amount you want to leave unspent)

y ≥ 1                                     (amount of dress shirt you need)

This is your system of equation, in which the numbers must fulfill both equations

hope this helps

Write the equation of an ellipse with a major axis of length 8 and co-vertices (0,3) and (0,-3)
alexandr1967 [171]
If the co-vertices are (0, 3) and (0, -3) where x is 0 and y has a value, then y is the minor axis.  That means that the x axis is the major axis.  Because of what the co-vertices are, the center of the ellipse is at the origin.  The formula for an ellipse that has a horizontal major axis is \frac{(x-h)^2}{a^2}+ \frac{(y-k)^2}{b^2}=1.  The a value will always be larger than the b value, therefore, the a value goes under the coordinate that is the major axis.  Here, its the x-axis.  a is the distance that the outer edge of the ellipse is from the center.  It's 8 units away from the center along the x axis and 3 units along the y axis from the center.  So a = 8 and a^2 = 64; b = 3 and b^2 = 9.  Our formula then is \frac{x^2}{64}+ \frac{y^2}{9}=1

Write the perimeter of each figure as a trinomial. <br> Must show your work.
noname [10]

Answer:

P = 2n + 8m - 1

Step-by-step explanation:

A <u>trinomial is an expression or equation that has three terms</u>. A term is when between the numbers or variables, the operations are neither subtraction nor addition, or when there is only one number.

If two terms have the <u>same variable</u>, called <u>like terms</u>, they can be combined by addition or subtraction.

The perimeter is the total length of all the sides.

The formula for the perimeter of a triangle is P = s_{1} + s_{2}  + s_{3} for each of the three sides.

Substitute each of the three sides.

P = s_{1} + s_{2}  + s_{3}

P = n + (2m + n)  + (6m - 1)

P = n + 2m + n  + 6m - 1 brackets can be removed

P = n + n + 2m + 6m - 1 rearrange equation according to like terms

P = 2n + 8m - 1 collected the like terms by addition

Find each product.<br><br> (5-x2+2)(-3)<br><br> PLEASE HELP!!! ASAP!!!
Bumek [7]

Answer:

3x^2 - 21 (did you mean for the equation to be (5 - x^2 + 2) \cdot -3?)

Step-by-step explanation:

Multiplying -3 by each term:

-3 \cdot 5 = -15

-x^2 \cdot -3 = 3x^2

-3 \cdot 2 = -6

-15-6 = -21

So the equation comes out to 3x^2 - 21 .

Hope this helped!
