Answer:

<h3>4</h3>

Step-by-step explanation:

- 1 | \frac{2}{3}  - 4|  \div  \frac{5}{6}  \\  - 1 | \frac{2}{3} -  \frac{4 \times 3}{1 \times 3}  |  \div  \frac{5}{6}  \\  - 1 | \frac{2 - 12}{3} |  \div  \frac{5}{6}  \\  - 1 | \frac{ - 10}{3} |  \div  \frac{5}{6}  \\  \frac{10}{3}  \div  \frac{5}{6}  \\  \frac{10}{3}  \times  \frac{6}{5}  \\  \frac{2}{1}  \times  \frac{2}{1} = 4

Determine the equation of the inverse of y=-4/x+1 The inverse is y=-a/x-b where a = a0 and b = a1
leva [86]
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant 

                                                -4
y = -4/x   +    1      or      y = ---------
                                               x+1

I'm going to assume that the latter is what you meant.

1.  Interchange x and y, obtaining:

               -4
     x = --------
             y+1

2.  Solve this for y, obtaining  y+1 = -4/x, or   xy + x = -4, or
                                
                                -x - 4
    xy = -x-4, or y = ---------
                                    x

                                   -1              -1                 4
3.  Replace y with    f      (x):      f    (x) = -1 - -----
                                                                         x

This last result has the correct form.</span>

Can someone plsss help me
balu736 [363]

Answer:

y = -5/3 x + 40

Step-by-step explanation:

The general form is y = ax + b, where a is the slope and b is the y intercept.

So immediately you can see that b must be 40, since the line crosses the y axis at 40.

The slope can be calculated by finding two "nice" points on the line that are also grid lines.

How about (0,40) and (6, 30).

Then, calculate the slope by dividing the y difference by the x difference:

(30-40)/(6-0) = -10/6 = -5/3

So C must be the answer.

What is the solution to the system of equations?
o-na [289]

Answer:

x = -5

y = 4

Step-by-step explanation:

3x + 4y = 1    /*(-4)

4x + 5y = 0   /*3

---------------------

-12x - 16y = -4

12x + 15y = 0     +

---------------------

-y = -4

y = 4

---------------------

12x = -15y

12x = -60

x = -5

---------------------
