the solution to the system of equation below is (−2, −1). 2x − 3y = −1 11x − 9y = −13 when the first equation is multiplied by −
Evgen [1.6K]
When the first equation is multiplied by -3, the sum of the two equation and any of the original equations will have the same solution as the original equations. Hence 5x = -10 and 11x - 9x = -13 will have a solution of (-2, -1).

cara is making a beaded necklace for a gift. she wants to spend more than $25 because she doesn´t want to seem like a cheap frie
snow_tiger [21]

Answer:

5 small beads!

Step-by-step explanation:

Hey there!

If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.

Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!

I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!

Have a wonderful day!

Nastasia [14]

Factor the trinomial

y^2+5y-24

by the box method.

The multiplication gives -24y^2. Now we need to find two factor that gives 5x. It should be creal that this factor are 8y and -3y. Then:

Now we find the common factor for each column and row:

Therefore:

y^2+5y-24=(y-3)(y+8)
