Which graph matches the equation y+6=3/4(x+4)?

Answer:

The equation of the function is

$\rightarrow y+6=\frac{3}{4} \times (x+4)\\\\4 \times (y+6)=3 \times (x+4)\\\\4 y+24=3x+12\\\\3x-4y=24-12\\\\3x-4y=12\\\\\frac{3x}{12}+\frac{4y}{-12}=1\\\\\frac{x}{4}+\frac{y}{-3}=1$

The function will cut x axis at (4,0) and y axis at (0,-3).

To draw a line you need two distinct points.

Draw a line passing through (4,0) and (0,-3).

In Exercise sketch the graph of the function.<br> f(x) = e - 2x + 1

Rus_ich [418]

Answer:

Attached linear graph

Step-by-step explanation:

The value of e is a mathematical constant of 2.72 approximately. We can consider this a constant as 1. Therefore this is a straight line with a gradient/slope of -2 and a y-intercept of:

$y=1+e=1+2.72=3.72$

and x intercept of:

$0=-2x+3.72$

$-3.72=-2x$

$x=1.86$

Is the function f(x) = -x its own inverse? <br> amos @audreyw2014

Assoli18 [71]

Answer:

f(x) and its inverse are the same

Step-by-step explanation:

<u>The inverse function </u>

If y=f(x), the inverse function $f^{-1}(x)$ is defined such as

$f(f^{-1}(x))=x$

To find the inverse function, there is a practical method:

a) Change letters x for y and vice-versa

b) Isolate y in terms of x only

c) $y=f^{-1}(x)$

In our case, $y=f(x)=-x$

a) Interchanging letters

$x=-y$

b) Isolate $y=-x$

c) $f^{-1}(x)=-x$

As we can easily see, f and its inverse are exactly the same

$f(x)=f^{-1}(x)$

The book Kathy is reading is 540 pages long. So far, she has read 405 pages. What percent of the book does she have left to read

PIT_PIT [208]

The book is 540 pgs.....she has read 405....that leaves (540 - 405) = 135 pgs left to read.

135 / 540 = 0.25 = 25% <== what she has left to read

The numbers on two consecutively numbered gym lockers have a sum of 137. what are the locker numbers ?

nika2105 [10]

Answer:

The two locker numbers are 68 & 69.

Step-by-step explanation:

Let one locker number be x then other will be , then other will be x+1.

We are given that sum is 137.

x+x+1=137

2x+1=137

2x=136

x = 68

The two locker numbers are 68 & 69.
