The graph shows the number of chairs made in a factory during one day .
GaryK [48]

Answer:

C) the factory produces 25 chairs per hour

                     

Step-by-step explanation:

Let's find the rate of change (slope):  

let:\\(x1,y1) =(2,50)\\(x2,y2)=(4,100)\\m=\frac{100-50}{4-2} =\frac{50}{2} =25 \\

Write an equation in slope-intercept form from the points (0, 3) and (-4,-1)
Bezzdna [24]

Answer:

y = x + 3

Step-by-step explanation:

Slope-intercept form is represented by the formula y = mx + b. We can write an equation in point-slope form first, then convert it to that form.

1) First, find the slope of the line. Use the slope formula  m = \frac{y_2-y_1}{x_2-x_1} and substitute the x and y values of the given points into it. Then, simplify to find the slope, or m:

m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1

Thus, the slope of the line must be 1.

2) Now, since we know a point the line intersects and its slope, use the point-slope formula y-y_1=m(x-x_1) and substitute values for m, x_1, and y_1. From there, we can convert the equation into slope-intercept form.

Since m represents the slope, substitute 1 in its place. Since x_1 and y_1 represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

y-3=1(x-0)\\y-3 = x\\y = x + 3

Which expressions are equivalint to 3x +2(x - 1) -4
Lerok [7]

Answer:

A.  3x +2(x - 1) -4 and B. 5x-6

Step-by-step explanation:

One of the answers is letter A because its the same exact expression as stated in the question. The other answer is B because of the distribution property you multiple x by 2 and multiply -1 by 2. This now gives us the expression 3x+2x-2-4. Now we add/subtract like terms and that gives the the answer 5x-6. I hope this helps.
