Answer:

j(x) = [ (3/10) cookie/student ]x

Step-by-step explanation:

The "unit rate" here is  

3 jumbo cookies

------------------------- = (3/10) cookie/student

       10 students

Then the number of cookies needed to feed x students is

j(x) = [ (3/10) cookie/student ]x

Answer:

  • x = -2
  • x = -3

Step-by-step explanation:

\bf {x}^{2}  + 5x + 6 = 0

Write the equation in factored form.

\bf (x + 2)(x + 3) = 0

Separate equations, and set each factor to zero.

\bf x + 2 = 0

\bf x  + 3 = 0

Rearrange and isolate the variable to find the solutions

\bf x =  - 2

\bf x =  - 3

------------------------------------

Answer please I’m really struggling with this
katovenus [111]

To write the any polynomial in standard form you must first put it in terms separated only by +,- operators, then you must order terms x^n descendingly according to n. In your case -\frac{1}{5}x^2 will be the first term because it has highest power, followed by -8x^1 and +7x^0.

The standard form of this specific polynomial is:

-\dfrac{1}{5}x^2-2x+7.

Hope this helps.

1 + 5sin^2x= 7sin^2x solve trig equation. Can you show me how to solve this trig equation?
pantera1 [17]

Answer: x = \frac{\pi}{4}\pm k\frac{\pi}{2}\,\,\,\,\,\,k=\{0,1,2,...\}

Step by step:

1 + 5\sin^2x= 7\sin^2x\\\sin^2 x\rightarrow z\\1 + 5z = 7z\\2z = 1\\z = \frac{1}{2}\implies \sin^2 x = \frac{1}{2}\\|\sin x| = \frac{1}{\sqrt{2}}\\\sin x = \pm\frac{1}{\sqrt{2}}=\pm\frac{\sqrt{2}}{2}\\\implies x = \frac{\pi}{4}\pm k\frac{\pi}{2}\,\,\,\,\,\,k=\{0,1,2,...\}

(Used a table of common angles)
