1 and 5/6 + 2 and 2/11

lions [1.4K]

$1 \frac{5}{6} +2 \frac{2}{11} =\frac{(1\times6)+5}{6} +\frac{(2\times 11)+2}{11} =\frac{11}{6}+\frac{24}{11} \\\\=\frac{11\times 11}{6\times 11} +\frac{24\times6}{11\times6} =\frac{121}{66} +\frac{144}{66}=\frac{121+144}{66} =\frac{265}{66}\\\\=\boxed{\bf{4\frac{1}{66}}}$

State the X- and Y- intercepts of each function. <br> 4x - 6y = 12

kupik [55]

X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y

Need help with this

Answer:

Step-by-step explanation:

Jamie is correct.

two angles are equal in an isosceles triangle.

let the angles be x,x,y

if she knows x

then y=180-(x+x)=180-2x

so she can find y

similarly if she knows y then she can calculate x.

Differentiate in respect to x

mixer [17]

Answer:

$e^{2x}(2x^3+3x^2)$

Step-by-step explanation:

Use the Product Rule (uv)' = uv' + u'v

$\frac{d}{dx}(x^3 e^{2x})=x^3\frac{d}{dx}(e^{2x})+\frac{d}{dx}(x^3)e^{2x}\\=x^3(2e^{2x})+3x^2e^{2x}\\=e^{2x}(2x^3+3x^2)$
