$= 1 \frac{1}{5} - \frac{1}{2}$

$= \frac{6}{5} - \frac{1}{2}$

$= \frac{12}{10} - \frac{5}{10}$

$= \frac{7}{10}$

For all parts of this question, use the function y + 2 = 3(x + 4)

vekshin1

i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier

y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis

y + 2 = 3x + 12. subtract 2 from both sides

y = 3x +10

now to fill in the chart simply plug in the value of x to see what value of y it produces

y = 3(-2) +10

y = -6+10

y = 4

(-2,4)

y = 3(0) + 10

y = 0 + 10

y = 10

(0,10)

y = 3(2)+10

y = 6 + 10

y = 16

(2,16)

y = 3(4) + 10

y = 12 + 10

y = 22

(4,22)

Find the mass of the triangular region with vertices (0, 0), (3, 0), and (0, 1), with density function ρ(x,y)=x2+y2.

ololo11 [35]

Since density is the ratio of mass to (in this case) area, we can find the mass of the triangular region $\mathcal T$ by computing the double integral of the density function over $\mathcal T$ :

$\mathrm{mass}=\displaystyle\iint_{\mathcal T}\rho(x,y)\,\mathrm dx\,\mathrm dy$

The boundary of $\mathcal T$ is determined by a set of lines in the $x,y$ plane. One way to describe the region $\mathcal T$ is by the set of points,

$\mathcal T=\left\{(x,y)\mid0\le x\le 3\,\land\,0\le y\le1-\dfrac x3\right\}$

So the mass is

$\mathrm{mass}=\displaystyle\int_{x=0}^{x=3}\int_{y=0}^{y=1-x/3}(x^2+y^2)\,\mathrm dy\,\mathrm dx$

$=\displaystyle\int_{x=0}^{x=3}\left(x^2y+\frac{y^3}3\right)\bigg|_{y=0}^{y=1-x/3}\,\mathrm dx$

$=\displaystyle\int_{x=0}^{x=3}\left(x^2\left(1-\frac x3\right)+\frac{\left(1-\frac x3\right)^3}3\right)\,\mathrm dx$

$=\displaystyle\frac1{81}\int_0^3(27-27x+90x^2-28x^3)\,\mathrm dx=\frac52$

Solve: z/2 + 26 > 17.5

Sophie [7]

Answer: Z> -17

z/2+26=17.5

We move all terms containing z to the left and all other terms to the right.

+ 0.5z=+17.5-26

We simplify left and right side of the equation.

+ 0.5z=-8.5

We divide both sides of the equation by 0.5 to get z.

z=-17

Find expressions for each of the following. Please make sure to show your work!

masha68 [24]

A)
g(a) = (3a - 5)^2 + 4a - 1

b)
g(a+2) = (3(a+2) - 5)^2 + 4(a+2) - 1
g(a+2) = (3a + 6 - 5)^2 + 4a + 8 - 1
g(a+2) = (3a +1)^2 + 4a + 7
