Identify the equation of the line graphed (I need help can someone explain)
Answer:
D.) 5x - 2y = 2
Step-by-step explanation:
1. Find all of the options and convert them to slope-intercept form by isolating y. If you isolate y on all of them, you should get that A is y =-2/5x - 1, B is y = 2/5x - 1, C is y = -5/2x - 1, and D is y = 5/2x - 1.
2. Use logic. This line cannot be negative, because negative lines go up to down, not down to up. That cancels out the possibility of A.) and C.) being answers. Now, we know that the slope has to be more than 1 because it is more compressed than that of a line with a slope of 1. The only slope that is more than 1 is D, so that makes D the answer (If you didn't understand this step, go to step 3).
3. Find the slope (This step does not need to be done if you understood Step 2). Take 2 points to be able to find the slope. Two random points on this line are (2,4) and (0,-1). Next, plug them into the formula to find slope. 4-(-1)/2-0 = 5/2, so the slope is 5/2. The only equation with a slope of 5/2 is D. D is the answer.
Answer: D.) 5x - 2y = 2

Answer:
AAS since if one of the side has a right angle that is one a straight line, then the other should be a right angle too. Since they also share a side, they must be congruent also, making it AAS.

Ben drove 230 kilometers in 3 hours, and Pia drove 250 kilometers in 3 hours. Without making any calculations, who drove faster?
Answer:
Pia drove faster than Ben, because they drove for the same amount of time, but Pia traveled farther. Pia drove 20 more kilometers than Ben, but she and Ben drove for the same amount of time.

Pam is having a yard sale. For each item, she is asking for two-fifths of the price for which she bought the item. Write an equation for the situation, where y is the price she is asking and x is the original price of the item.
Answer:
The equation is 2x = 5y
Step-by-step explanation:
From the question, we are told that what is asked is 2/5 of the price for which each of the items are bought
y is the asking price, x is the original
Mathematically,
that would be;
y = 2/5 * x
y = 2x/5
Thus;
2x = 5y

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of variation in this scenario?
Answer:
27,576
Step-by-step explanation:
In the text it has a table that is titled Cost Source.
Cost Source Cost in U.S. Dollars
Operating Costs/Acre $27,576
Cash Overhead $4,873
TOTAL CASH COSTS/ACRE $32,449
It looks Somewhat like that.
The answer you can see was in Operating Cost/Acres.
Which linear inequality is represented by the graph?
O y > 2x + 2
O yz 2x + 1
Oy> 2x + 1
O y z 2x+2
By analyzing the graph, we will see that the inequality is:
y > 2x + 1
How to know the inequality represented by the graph?
From a first look, we can see two things.
The line is a dashed line, so the values on the line are not solutions.The shaded region is above that line.From that we can conclude that the inequality is something like:
y > line.
To find the equation of the line, we can look at the graph.
We can see that it intercepts the y-axis at y = 1, and for each increase of one unit in the x-axis increases 2 units on the y-axis, so the line is:
2x + 1
Then the inequality is:
y > 2x + 1.

9514 1404 393
Answer:
P = 250 +50t
Step-by-step explanation:
We are given two pairs of time and price:
(t, P) = (0, 250) and (5, 500)
We can put these into the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
P = (500 -250)/(5 -0)(t -0) +250
P = 250/5t +250
P = 50t +250 . . . . Madelyin's cost equation

Select all angles that MUST be supplementary to 9
Answer:
Angles supplementary to angle 9 = Angle 10, 7, 5, 1, 4, 3, 15, 12, 24, 22, 20, 19, and angle 16.
Step-by-step explanation:
Use the vertical, and corresponding angles theorem to find congruent angles.
Look for linear pairs (adjacent(next to each other, or share a side) angles that make 180° or a straight angle) from the corresponding angles.
Something is supplementary if it adds to 180 degrees.
The vertical angles theorem states that pairs of opposite angles made by interesecting lines are congruent.
The corresponding angles theorem states that corresponding or angles relative to the same position are congruent if the transversal crosses at least 2 parallel lines.

Answer:
[tex]\sqrt{-19} , -3.5, 3/2, \sqrt{20} , 4.9[/tex]
Negative numbers go first, the greater the number, the smaller the number.
Answer:
-√19,-3.5, √20, 4.9, 1/2
Step-by-step explanation:
Find the square root of 19 ( Which you can't) always have the negatives go first because negatives are the greatest. Find the square root of 20, which equals 4.4, then divided 3/2 which gives you 1.5. I hope this helped! I'm not the best at explaining either.
