Answer:
D. 200-2/3x=2/5
Step-by-step explanation:
You can tell that one side of the equation is going to have only 2/5 because the problem said there was 2/5 of a ton left. You can also figure out that the equation should say 200-2/3x because the problem said that the conveyor belt removes 2/3 of a ton per minute. So, the equation should be...
200-2/3x=2/5, which is D.
Hope this helps c:
Answer: D
Step-by-step explanation:
The 2/3 is the rate and there is 2/5 leftover from the original 200 tons.

Veronica is given a rectangular piece of paper. If the length of Veronica's piece of paper is represented by x2 + 6x – 2 and the width is represented by 3x - 5, find the area of the piece of paper.
Answers
Answer:
3x^3 +13x^2 - 36x + 10.
Step-by-step explanation:
Area = length * width
= (3x - 5)(x^2 + 6x - 2)
= 3x(x^2 + 6x - 2) - 5)(x^2 + 6x - 2)
= 3x^3 + 18x^2 - 6x - 5x^2 - 30x + 10
= 3x^3 + 13x^2 - 36x + 10.

What is the difference between a linear function and a nonlinear function? Explain what each looks like when represented as a table and as a graph.
Answers
Answer:
Sample Answer: A linear function has a constant rate of change, while a nonlinear function does not. For a table of values to be linear, the outputs must have a constant rate of change as the inputs increase by 1. On a graph, the function must be a straight line to be linear.
Answer:
On a graph, it is easy to remember whether a function is linear or nonlinear. Nonlinear means the graph is not a straight line. The graph of a nonlinear function is a curved line. If it is straight, then it is linear. On a table, you can determine whether a function, in tabular form, is nonlinear by observing that the jump in y varies for each unit of change in x.

the sum of the second and fourth of four consecutive integers is 110
Answers
Answer:
The integers: 53, 54, 55, 56
Step-by-step explanation:
Consecutive integers increase by 1, so if x is the smallest one, then the numbers are:
x, x+1, x+2, x+3
the sum of the second and fourth: x+1 + x+3 = 2x+4
so: 2x + 4 = 110 ⇒ 2x = 106 ⇒ x = 53
So the integers we are looking for:
53, 54, 55, 56

Write an equation of the line passing through the point (7, 3) that is parallel to the line 4x−7y=9.
Answers
Answer:
The equation of the line is y = 4x/7 - 1
Step-by-step explanation:
The equation of a straight line can be represented by
y = mx + c
where m represents the slope and c represents the y-intercept
So for;
4x - 7y = 9
7y = 4x - 9
y = 4x/7 - 9/7
The slope here is 4/7
Since the line we are trying to form is parallel, then the slope of the line is 4/7 also, since parallel lines have equal slope
So the equation of the new line will be;
y = 4x/7 + c
To get c, just put the point x = 7 and y = 3
3 = 4/7(7) + c
3 = 4 + c
c = 3-4
c = -1
So the equation of the line is;
y = 4x/7 - 1
