Answer:

y= -3x-12

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.

Given that the slope is -3, m= -3.

Substitute the value of m into the equation.

y= -3x +c

Now, substitute the given coordinates into the equation.

When x= -5, y= 3,

3= -3(-5) +c

3= 15 +c

c= 3 -15

c= -12

Hence, the equation of the line is y= -3x-12

The area of a rectangular field is 6942 m
Nuetrik [128]

The required length of the rectangle is 89 m.

Given that,
The area of a rectangular field is 6942 m. If the width of the field is 78 m, what is its length is to be determined.

<h3>What is the perimeter?</h3>

Perimeter is the measure of the figure on its circumference.

<h3>What is a rectangle?</h3>

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

The area of the rectangle = length * width
                                6942  = length * 78
                                length = 89 m

Thus, the required length of the rectangle is 89 m.

Round 1.239 to the nearest hundred
Angelina_Jolie [31]
1.24 because the places after the decimal go decimal tenth hundredth thousandth so you look at the second place after the decimal. Then you look at the number after it. In this case because the third number is above a four, it "rounds" up so the three changes to a four. So the answer is 1.24. Hope this helped :)

Step-by-step explanation:

Spongebob bought a total of 4.5 pounds of Krabby Patties and fries at the Krusty Krab. He bought 2.75 pounds of Krabby Patties.

Write and solve an equation to find how many pounds of fries, f, Spongebob bought.

The number of pounds of fries that sponge Bob bought is calculated as:

Total of pounds of Krabby Patties and fries at the Krusty Krab - Number of pounds of Krabby Patties.

f = 4.5 pounds - 2.75 pounds

f = 1.75 pounds of fries
