<h2><em>Answer:</em></h2>

\fbox{Surface \: area \: of \: prism = 520 \: sq.in.}

<h3><em>Step by step explanation:</em></h3>

<em>Given:</em>

height of prism h = 10 in

length of base of triangle b = 8 in

height of triangle h' = 15in

side A of triangle = 17 in

<em>To find:</em>

Surface area of prism = ?

<em>Solution:</em>

\begin{gathered}Area \: of \: base \: triangle = \: \frac{1}{2}\cdot{b}{h'} \\ Area \: of \: base \: triangle = \frac{1} {\not2}\cdot{15} \times \not{8} \\ Area \: of \: base \: triangle = 60 \: {in}^{2} \end{gathered}\\\fbox{Area \: of \: base \: triangle \: (B) = 60 \:   sq.in. }\\\begin{gathered}Perimeter \: of \: base \: triangle = Side A + Height \:  h' + base \:  b \\ Perimeter \: of \: base \: triangle = 15 + 17 + 8 \: in\\ Perimeter \: of \: base \: triangle = 40 \: in\end{gathered}

\fbox{Perimeter \: of \: base \: triangle (p) \: = 40 \: in}

\begin{gathered}Surface \: area \: of \: prism = 2B+ \: ph \\ Surface \: area \: of \: prism = 2 \times 60+ \: 40 \times 10 \\ Surface \: area \: of \: prism = 120 + 400\\ Surface \: area \: of \: prism = 520 \: {in}^{2} \end{gathered}

\fbox{Surface \: area \: of \: prism = 520 \: sq.in.}

Solve for x and y simultaneously:<br> X-2y=3<br> 4xsquared-5xy+6y=3
Mkey [24]
X - 2y = 3
<span>4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(</span>3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2<span> - 15y - </span><span>10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- </span>√(33^2 - 4*6*33)<span>)/12
</span>y = (-33 +- √(297)<span>)/12
</span>so there are 2 solutions for y:
y1 = (-33 + √(297)<span>)/12
</span>y2 = (-33 - √(297)<span>)/12
</span>pick one and then substitute the y value in the first equation to find x

Which graph represents the linear function y = x 3/4– 4?
ahrayia [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=\frac{3}{4}x-4

This is a linear equation (the graph is a line)

To identify the graph find out the intercepts

<u><em>Find out the y-intercept</em></u>

The y-intercept is the value of y when the value of x is equal to zero

For x=0

y=\frac{3}{4}(0)-4=-4

The y-intercept is the point (0,-4)

<u><em>Find out the x-intercept</em></u>

The x-intercept is the value of x when the value of y is equal to zero

For y=0

0=\frac{3}{4}x-4

\frac{3}{4}x=4

x=16/3=5.33

The x-intercept is the point (5.33,0)

therefore

The graph in the attached figure
