Answer:

Step-by-step explanation:

For a function to be decreasing over an interval, the outputs on the function are getting smaller as the inputs of the function are getting larger, but the outputs could be positive or negative. For a function to be negative over an interval, the outputs must be negative, while the inputs could be positive or negative.

The scatterplot shows the distance (in feet) that a person was from a motion sensor during an experiment in math class. Use the

iragen [17]

Answer:

B.) 27ft

Step-by-step explanation:

The labeled points given: (5,18) and (1.5, 7.5)

Slope = (18 - 7.5)/(5-1.5) = 10.5 / 3.5 = 3

A linear model:

y - 18 = 3(x - 5)

y - 18 = 3x - 15

y = 3x + 3

If x = 8 seconds then the distance in feet (y) would be: (plug in x = 8 into the equation y = 3x + 3)

y = 3(8) + 3

y = 24 + 3

y = 27 ft

Answer:

B.) 27ft

What is the slope of the line that contains the points (-1,2) and (3,3)?

Semmy [17]

Answer:

1/4

Step-by-step explanation:

To find the slope of a line from two points we use

m = (y2-y1)/(x2-x1)

m = (3-2)/ (3--1)

= (3-2)/(3+1)

=1/4

A grocery store clerk put only packages of flour tortillas and packages of corn tortillas on a shelf. The ratio of the number of

Likurg_2 [28]

Answer: 18

Step-by-step explanation:

The options are:

A. 23

B. 18

C. 14

D. 32

Since we are told that the ratio of the number of packages of corn tortillas to the total number of packages on the shelf was 7 to 16. This simply means that the ratio of flour tortillas to the total number of packages on the shelf was (16 -7 = 9) 9 to 16.

Therefore, to get the number that could represent the number of packages of flour tortillas the clerk put on the shelf we have to find the multiple of 9 in the question given . This will be:

Multiples of 9 = 9, 18, 27, 36, 45 ....

Based on the option, the answer will be 18.
