The answer is 8% because each rate (2%) goes up $200, making $1200 at 6% into $1800 at 8%.

Hope this helps!

Help with this algebra question
choli [55]
If two lines are perpendicular, the slope of one of the lines is the negative reciprocal of the other. Since we know the slope for one of our lines, 2m lets find the other:
m=- \frac{1}{2}

Now, lets use the point-slope formula to complete the equation of our perpendicular line:
y-y_{1}=m(x-x_{1})
y-5=- \frac{1}{2} (x-2)
y-5=- \frac{1}{2}x+1
y=- \frac{1}{2} x+6

We can conclude that our perpendicular line is y=- \frac{1}{2} x+6

What types of lines are coplanar and intersect at a right angle?
Aleonysh [2.5K]

Answer: hope this help's

Step-by-step explanation:

Geometry Terms Chapter 3

A B

Coplanar in the same plane

Parallel lines coplanar lines that do not intersect

Intersecting lines coplanar lines that have exactly one point in common

Perpendicular lines lines that intersect at righ- are non-coplanar

- they are not parallel and do not intersect

t angles     are non-coplanar

- they are not parallel and do not intersect

- planes that do not intersect        - two segments are parallel if the lines containing them are parallel           - a line that intersects two or more coplanar lines at different points

- transversal has nothing to do with whether lines are parallel or not          - an angle formed between parallel lines by a third line that intersects them

lie on the same side of the transversal and in corresponding positions

alternate exterior angles

- non-adjacent exterior angles that lie on opposite sides of the transversal

10/56     hope this help you a lot better

The price of some houses in a neighborhood are shown below: House Price A $120,000 B $130,000 C $140,000 D $150,000 E $1,110,000
LenaWriter [7]

Answer:

To infer a price for the houses in that neighborhood, it is better to use the median.

Step-by-step explanation:

We have the following prices:

$ 120,000

$ 130,000

$ 140,000

$ 150,000

$ 1,110,000

Now, if we do it for the median, it is the best option, because there is a very distant value and the median is not much affected. The value that is inferred through the average is $ 140,000, a value close to the first 4 houses.

If we do it by the mean, the value would be:

(120,000 + 130,000 + 140,000 + 150,000 + 1,110,000) / 5 = $ 330000

a value very far from all the prices of the houses, this is due to the value so far from the last house.

In other words, to infer a price for the houses in that neighborhood, it is better to use the median.
