Graph B is the answer

First I would isolate the "y" in the inequality(you don't have to but it makes the inequality look simpler):

y - 5 > 2x - 10 Add 5 on both sides

y > 2x - 5

[This is kind of the same form as y = mx + b ("m" is the slope, "b" is the y-intercept (when x = 0)), except there is a sign(< , > , ≤, ≥) instead of an equal sign. So your slope is 2, and your y-intercept is -5.]

Only when the sign is ≤ or ≥ ("less/greater than or equal to"), the line is a solid line. When the sign is < or >, the line is a dotted line.

Based on the inequality, "y" is greater than the line (2x - 5), so the shaded area would be above the line. And because the sign does not have a line underneath, it is a dotted line.

Your answer is B

Quadrilateral ABCD is dilated by a scale factor of 2 centered around (2, 2). Which statement is true about the dilation?

arsen [322]

Answer:

Option (B) is true i.e segment B'D' will run through (2,2) and will be longer than the segment BD.

Step-by-step explanation:

As the assumption quadrilateral ABCD is shown in figure a.

First located the center of the dilation which is located at (2,2) as shown in figure b.

The next thing we want to do is to determine the distance of the center of dilation to each of the points of quadrilateral ABCD as shown in figure b.

Let’s just start with the distance from the center to the point A, but notice we don’t have to move up and down in y direction. So, what we have to do is to increase this by the factor 2. Because this horizontal distance is 1 i.e. the distance from dilation center (2,2) to point A, we just have to multiply by 2 which would be a distance of 2 and this point right here will be the new location of point A’ (0,2).

And the distance from the center to the point C is the horizontal distance of 2 i.e. the distance from dilation center (2,2) to point C, we just have to multiply by 2 which would be a distance of 4 and this point right here will be the new location of point C’ (6,2).

And the distance from the center to the point B is the upward vertical distance of 1 i.e. the distance from dilation center (2,2) to point B, we just have to multiply by 2 which would be a vertical distance of 2 and this point right here will be the location of point B’ (2,4).

And similarly the distance from the center to the point D is the downward vertical distance of 1 i.e. the distance from dilation center (2,2) to point D, we just have to multiply by 2 which would be a vertical distance of 2 and this point right here will be the location of point D’ (2,0).

So, Quadrilateral A'B'C'D' is dilated by a scale factor of 2 centered around (2, 2).

Just notice in figure b that the segment B'D' will run through (2,2) and will be longer than the segment BD.

So,option (B) is true i.e segment B'D' will run through (2,2) and will be longer than the segment BD.

20,000 pounds equals how many English tons?

kkurt [141]

2,000 pounds are a short ton also sometimes referred to as an English ton. Your 20,000 pounds are therefore 10 short tons. By contrast the Metric ton is 1,000 kg or 2,204 American pounds. 2000 pounds = 1 short ton 2240 pounds = 1 long ton

Day 2- Real World- Midpoint

nevsk [136]

Answer:

Point of the flower garden R ( 11, 44 )

Step-by-step explanation:

Let´s call P ( 3, 14 ) The center of the herb garden, and Q ( 7 , 29 ) the birdbath point

Differences in coordinates of these two points are:

x axis 7 - 3 = 4

y axis 29 - 14 = 15

Then the point Q ( x , y ) will be at: Q ( 11, 44)

x axis x = 11 because 7 + 4 = 11 means that the coordinate 7 is just halfway way between coordinates (x) 3 and 11 ( 4 above 3, and 4 below 11)

Reasoning the same way we conclude y = 44 in this case 29 is just halfway between coordinates (y) 14 and 44 ( 15 above 14 and 15 below 44)

We can probe getting distance d₁ between P and Q and d₂ distance between Q and R as:

d₁ = √ (7-3)² + ( 29-14)²

d₁ = √ 16 + 225

d₂ = √ (11 - 7)² + ( 44 - 29)²

d₂ = √ 16 + 225
