Answer:

y = -4

Step-by-step explanation:

Combine the y terms.  To do this, add 0.3y to both sides, which results in:

5.1y + 0.3y = -21.6, or

5.4y = -21.6

Dividing both sides by 5.4 yields the desired result:

y = -21.6/5.4 = -4

The table shows the number of badges earned, based on the number of boxes of cards sold. What does b(20) = 3 mean in terms of th
valina [46]

Answer:

b(20) = 3 means that for 20 boxes of cards sold, 3 badges were earned.

Step-by-step explanation:

The number of badges earned based on the number of boxes of cards sold means that badges earned are a function of the number of boxes of cards sold.

b(20) means the number of badges earned for selling 20 boxes of cards.

b(20) = 3 means that for 20 boxes of cards sold, 3 badges were earned.

How do you factor this in the form (x+b)(x+c)
faust18 [17]
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!

<u>Geometry</u>

Volume Formula [Cylinder]:
\displaystyle V = \pi r^2 h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>h</em> = 5 cm

<em>r</em> = 10 cm

<u>Step 2: Find Volume</u>

  1. [Volume Formula - Cylinder] <em>Substitute</em> in variables:
    \displaystyle V = \pi (10 \ \text{cm})^2 (5 \ \text{cm})
  2. [Order of Operations] Evaluate:
    \displaystyle V = 500 \pi \ \text{cm}^3
  3. Approximate:
    \displaystyle V \approx \boxed{ 1570.8 \ \text{cm}^3 }

∴ the volume of a cylinder whose height is 5 cm and radius is 10 cm is <em>approximately</em> 1570.8 cm³.

5x=15 y 2x=6 <br> Son ecuaciones equivalentes?<br><br> PORFAVOR AYÚDENME ES EMERGENCIA
mihalych1998 [28]
Si, los dos son iguales

Cuando haces 5x=15, la división dice que x = 3. Para 2x=6 puedes usar el resultado de x=3 de la problema de antes, y cuando te usas esto va a ver que 2 de x cuando x=3 es igual a 6, y por eso 5x=15 y 2x=6 son equivalentes.
