Answer:

y = mx + b is  the "slope-intercept" form of the equation of a line ;

We have y = -x + 6 ;

Then, m = - 1 ;

The "point-slope" form of the equation of a straight line is:

y - y1 = m(x - x1) ;  

But, x1 = - 3 and y1 = 8 ;

We have y - 8 = (-1)( x + 3 );

Finally, y - 8 = -( x + 3 );

The right answer is the fourth choice;

________________________________________

y – 3 = (x – 1) ; the equation becames

y = x + 2 ;  

The right answer is the third choice;

A farmer needs to ship 71 pumpkins to a grocery store if each crates can hold 19 pumpkins how many crates Will the farmer need ?
Lesechka [4]

Answer:

The farmer will need 7 crates.

Step-by-step explanation:

<em>It is given that there are 71 pumpkins in total.</em>

<em>And each crate holds 19 pumpkins.</em>

Let the number of crates required be<em> "n".</em>

The total number of pumpkins can be calculated by multiplying number of pumpkins in each crate with total number of crates.

Thus, the equation is

19(n) = 71

n = \frac{71}{19} = 7

Thus, the farmer needs 7 crates to hold total of 71 pumpkins.

Answer: 40 unit²

Step-by-step explanation:

A square pyramid is composed of 1 square and 4 congruent triangles

STEP ONE. Find the area of the square.

A=b²

b=base

A=b²=4²=14

STEP TWO. Find the area of the triangle

A=(1/2)bh

b=base

h=height

A=(1/2)bh

A=(1/2)(4)(3)

A=(1/2)(12)

A=6

There are 4 congruent triangles, so 6×4=24

The surface area of whole=24+16=40 unit²

Hope this helps!! :)
