{(-3, 7.5) , (-2, 10) , (-1, 12.5)} arithmetic or geomatic

Mathematics
1 answer:
marysya [2.9K]3 years ago
4 0

Answer:

arithmetic

Step-by-step explanation:

The points fall on a straight line. They won't do that for a geometric sequence.

___

Normally the terms of either sort of sequence are numbered with counting numbers: 1, 2, 3, .... Your x-values are negative, so are obviously not term numbers of a sequence. The differences of x-values are 1, and the differences of y-values are 2.5, so we know the x- and y-values are linearly related. That relationship can be expressed in point-slope form by ...

y = 2.5(x +1) +12.5

which can be simplified to

y = 2.5x +15

__

The arithmetic sequence with first term 17.5 and common difference 2.5 would be described by this same equation.

PLEASE HELP <br> WHAT ARE THE coordinates for the center of the hyperbola??
solong [7]

Answer:

The coordinates of the center of the hyperbola are (1,-3)

Step-by-step explanation:

Equation of a hyperbola:

The equation of a hyperbola with center (x_0,y_0) is given by:

\frac{(x - x_0)^2}{a^2} - \frac{(y - y_0)^2}{b^2} = 1

In this question, we have that:

-x_0 = -1 \rightarrow x_0 = 1

-y_0 = 3 \rightarrow y_0 = -3

The coordinates of the center of the hyperbola are (1,-3)

Deandra is doing her math homework. Out of 24 problems total, she completed the first 12 problems in 1 hour and the last 12 in 3
Bezzdna [24]

Answer:

6 problems per hour

Step-by-step explanation:

Total problems = 24

she completed the first 12 problems in 1 hour

The last 12 in 3 hours.

Total time = 1 hour + 3 hours

= 4 hours

unit rate for all 24 problems = total number of problems / total time taken

= 24 problems / 4 hours

= 6 problems per hour

How do you the equation of the line that passes through point (-3,2) and is parallel to the line formed by the equation y = 4x +
hjlf

Answer:

y = 4x + 14

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x + 7 ← is in slope- intercept form

with slope m = 4

• Parallel lines have equal slopes , then

y = 4x + c ← is the partial equation

to find c substitute (- 3, 2 ) into the partial equation

2 = - 12 + c ⇒ c = 2 + 12 = 14

y = 4x + 14 ← equation of parallel line

On a coordinate plane the coordianits of vertices the and t for a polygon are r(-7,3) and r (3,3) what is the length of side rt
NemiM [27]

The length is 10.


Since the two points share the same y-coordinate, the segment rt is horizontal.


This means that the length of the side is simply the difference (in absolute value) between the x coordinates of the two points.


So, we have


\overline{RT} = |-7-3| = |-10| = 10
