Answer:

  2 .The slope of Function A is less than the slope of Function B

Step-by-step explanation:

A graph of Function A shows it has a y-intercept of 4, the same as that of Function B. (Statements 3 and 4 are not correct.)

The slope of Function A is 2, which is less than the slope of 3 that Function B has. (Statement 2 is correct; statement 1 is not.)

_____

<em>More detailed working</em>

The slope of Function A can be figured easily between the points with x-values that differ by 1:

  m = (y3 -y2)/(x3 -x2) = (24-22)/(10-9) = 2/1 = 2 . . . . . Fun A has slope of 2.

The slope of Function B is the coefficient of x in the equation: 3.

__

The y-intercept of Function A can be found starting with point-slope form:

  y -22 = 2(x -9)

  y = 2x -18 +22

  y = 2x +4 . . . . . . . slope-intercept form

The intercept of +4 is the same as that of Function B.

Allisa [31]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Sum of the interior angles of any triangle is 180° .

Thus ;

y + 48° + 90° = 180°

y + 138° = 180°

Subtract sides 138°

y + 138° - 138° = 180° - 138° \\

y = 42°

a company manufactures rectangular cardboard boxes. each box is 20 inches long and 15 inches wide. the heights of the boxes rang
Bogdan [553]

The range of possible values for the volume of the boxes would be 1200 - 1800 cubic inches

The dimensions of the rectangular cardboard boxes are given as

Case I

Length = 20 inches

breadth = 15 inches

Height = 4 inches

Volume of the rectangular cardboard box in case I = Length x breadth x breadth

= 20 x 15 x 4

= 1200 cubic inches

Similarly,

Case II

Length = 20 inches

breadth = 15 inches

Height = 6 inches

Volume of the rectangular cardboard box in case I = Length x breadth x breadth

= 20 x 15 x 6

= 1800 cubic inches
