Opposite sides are equal
.. VR = TS
.. y = x +11

.. VT = RS
.. y -3x = x +2

You can use the first equation to subsitute for y in the second equation.
.. x +11 -3x = x +2
.. 9 = 3x . . . . . . . . . . add 2x -2
.. 3 = x . . . . . . . . . . . divide by 3
.. y = 3 +11 = 14 . . . . substitute for x in the equation for y

The value of x is 3.
The value of y is 14.

Two sides of a triangle are 8 m and 9 m in length and the angle between them is increasing at a rate of 0.06 rad/s. Find the rat

Lelechka [254]

<h2>Rate at which area is increasing is 1.08 m²/s.</h2>

Step-by-step explanation:

Area of triangle is with side a and b and angle C between them is given by

A = 0.5 ab SinC

Here we need to find how area changes with a and b fixed and C is changing,

$\frac{dA}{dt}=\frac{d}{dt}\left (0.5 absinC\right )\\\\\frac{dA}{dt}=0.5ab\frac{d}{dt}\left (sinC\right )\\\\\frac{dA}{dt}=0.5abcosC\frac{dC}{dt}$

We have

a = 8 m

b = 9 m

$C=\frac{\pi}{3}rad\\\\\frac{dC}{dt}=0.06rad/s$

Substituting

$\frac{dA}{dt}=0.5\times 8\times 9\times cos\left ( \frac{\pi}{3}\right )\times 0.06\\\\\frac{dA}{dt}=1.08m^2/s$

Rate at which area is increasing is 1.08 m²/s.

If the function f is given by f(x)= 4x -3, find the value of f(2+h)

Travka [436]

f(x)=4x-3

$\\ \sf\longmapsto f(2+h)$

$\\ \sf\longmapsto 4(2+h)-3$

$\\ \sf\longmapsto 4h+8-3$

$\\ \sf\longmapsto 4h+5$

4y = 9x - 21<br> y = x-4

Anastaziya [24]

Answer:

x = 1

y = -3

Step-by-step explanation:

if y = x - 4

then reorganise the first equation

4 (x - 4) = 9x -21

4x - 16 = 9x - 21

5 = 5x

x = 1
