Solve 2y - 5 over 3 = 4y - 1 over 2

ololo11 [35]

$\frac{2y - 5}{3} = \frac{4y - 1}{2}$
$3(4y - 1) = 2(2y - 5)$
$3(4y) - 3(1) = 2(2y) - 2(5)$
$12y - 3 = 4y - 10$
$8y - 3 = -10$
$8y = -7$
$\frac{8y}{8} = \frac{-7}{8}$
$y = -0.875$

What is the Equation of this Trend line<br><br> K=_ J+_

Yuri [45]

Answer:so the standard form is y = mx + b

m is the slope (rise/run)

b is the y-intercept or where the slope intercepts the y-axis

so you end up with

k = (4/-2)j + 24

simplify this to

k = -2j + 24

What is the surface area of this triangular prism

const2013 [10]

The perimeter of the triangular end is 12 m, so the total rectangular area is
.. (12 m)*(8 m) = 96 m^2

There are two triangles with base 3 m and height 4 m, so their total area is
.. (3 m)*(4 m) = 12 m^2

The surface area of the figure is the sum of these
.. 96 m^2 +12 m^2 = 108 m^2

The one-to-one functions g and h are defined as follows

Debora [2.8K]

Answer:

$g^-^1(x)=-8$

$h^-^1(x)=\frac{x-4}{3}$

$(h^-^1 \ o\ h)(-3)=-3$

Step-by-step explanation:

When given the following functions,

$g=[(-2,-7),(4,6),(6,-8),(7,4)]$

$h(x)=3x+4$

One is asked to find the following,

1. Question 1

$g^-^1(4)$

When finding the inverse of a function that is composed of defined points, one substitutes the input given into the function, then finds the output. After doing so, one must substitute the output into the function, and find its output. Thus, finding the inverse of the given input;

$g^-^1(4)$

$g(4)=6\\g(6)=-8\\g^-^1(4)=-8$

2. Question 2

$h^-^1(x)$

Finding the inverse of a continuous function is essentially finding the opposite of the function. An easy trick to do so is to treat the evaluator (h(x)) like another variable. Solve the equation for (x) in terms of (h(x)). Then rewrite the equation in inverse function notation,

$h(x)=3x+4\\\\h(x)-4=3x\\\\\frac{h(x)-4}{3}=x\\\\\frac{x-4}{3}=h^-^1(x)$

$h^-^1(x)=\frac{x-4}{3}$

3. Question 3

$(h^-^1 \ o\ h)(-3)$

This question essentially asks one to find the composition of the function. In essence, substitute function (h) into function ( $h^-^1$ ) and simplify. Then substitute (-3) into the result.

$h^-^1\ o\ h$

$\frac{(3x+4)-4}{3}\\\\=\frac{3x+4-4}{3}\\\\=\frac{3x}{3}\\\\=x$

Now substitute (-3) in place of (x),

$=-3$
