The slope of line passing through (2,-2) and (9,3) is 5/7

Step-by-step explanation:

Given two points are:

(x1,y1) = (2,-2)

(x2,y2) = (9,3)

The slope is defined as the steepness of a line.

When two points are known, through which the line passes,

The slope is given by:

m = \frac{y_2-y_1}{x_2-x_1}

Putting the values

m = \frac{3-(-2)}{9-2}\\m = \frac{3+2}{7}\\m = \frac{5}{7}

Hence,

The slope of line passing through (2,-2) and (9,3) is 5/7

Examplelt: A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall
harina [27]

Answer :

  • 4167 bricks.

Explanation :

Since the wall with all its bricks makes up the space occupied by it, we need to find the volume of the wall, which is nothing but a cuboid.

Here,

{\qquad \dashrightarrow{ \sf{Length=10 \: m=1000 \: cm}}}

\qquad \dashrightarrow{ \sf{Thickness=24 \: cm}}

\qquad \dashrightarrow{ \sf{Height=4 m=400 \: cm}}

Therefore,

{\qquad \dashrightarrow{ \bf{Volume \:  of  \: the  \: wall = length \times breadth \times height}}}

{\qquad \dashrightarrow{ \sf{Volume \:  of  \: the  \: wall = 1000 \times 24 \times 400 \:  {cm}^{3} }}}

Now, each brick is a cuboid with Length = 24 cm, Breadth = 12 cm and height = 8 cm.

So,

{\qquad \dashrightarrow{ \bf{Volume \:  of  \: each  \: brick = length \times breadth \times height}}}

{\qquad \dashrightarrow{ \sf{Volume \:  of  \: each  \: brick = 24 \times 12 \times 8 \:  {cm}^{3} }}}

So,

{\qquad \dashrightarrow{ \bf{Volume \:  of  \: bricks  \: required =  \dfrac{volume \: of \: the \: wall}{volume \: of \: each \: brick} }}}

{\qquad \dashrightarrow{ \sf{Volume \:  of  \: bricks  \: required =  \dfrac{1000 \times 24 \times 400}{24 \times 13 \times 8} }}}

{\qquad \dashrightarrow{ \sf{Volume \:  of  \: bricks  \: required =   \bf \: 4166.6} }}

Therefore,

  • <u>The wall requires 4167 bricks. </u>

B, D, F, and H

Step-by-step explanation:

You substitute in each of the numbers for x and see if it equals one of the values in the range. {-37, -25, -13, -1}

A)  -6(1)+11=-5 NO

B)  -6(2)+11=-1 YES

C)  -6(3)+11=-7 NO

D)  -6(4)+11=-13 YES

E)  -6(5)+11=-19 NO

F)  -6(6)+11=-25 YES

G)  -6(7)+11=-31 NO

H)  -6(8)+11=-37 YES

So the ones to select are B, D, F, and H.
