Your answer is m=-1/7<span> or </span><span>-0.143. All you need to do is add 3 by -4. You then get -1.</span>

The answer would be m = -1/7 or -0.143

Since we are given the value of b (-3) and a coordinate (7, -4), All you have to do is plug the x-coordinate into x and the y-coordinate into y; simplifying the equation to (-4 = m*7-3). Using simple algebra, find m by adding 3 to -4. Finally, divide that by 7 to get your final answer, (-1/7).

Answer:

V = 8 × 6 × 3

V = 48*3

Step-by-step explanation:

V = l*w*h

We know the length is 8, the width is 6 and the height is 3

V = 8*6*3

V = 48*3

Creating a One-Variable Equation to Model and Solve a Problem

Answer:

The hourly fee for rototiller is $3 per hour.

Step-by-step explanation:

We are given the following in the equation:

The rental company charged an initial fee of $43 with an additional fee per hour.

Let h represents the hourly fee.

The family paid $64 after renting the rototiller for 7 hours.

Thus, we can write the equation:

$43 + 7h = 64$

Solving the equation, we get,

$43 + 7h = 64\\7h = 64-43\\7h = 21\\\Rightarrow h = 3$

Thus, the hourly fee is $3 per hour.

Equation:

$C(x) = 43 + 3x$

where C(x) is the cost function and x is the number of hours rototiller is rented.

The hourly fee for rototiller is $3 per hour.

Idk how to do this honestly

Anuta_ua [19.1K]

I get the answer being the same y= -1/2x +

Because b in intercept form is "0"

I used
m=y2-y1/x2-x1
M=-3-2/6-4
M=-5/10
M=-1/2

(-4,2)
Y=mx+b
2=-1/2 (-4)+b
B=2-(-1/2)(-4)
B=0

I did the same for second point
And got "0" for b

So my answer is get
Y=-1/2x

Unless someone else gets something else different.

I hope somewhat helps
