What type of quadrilateral is created by the points:<br><br> L (-5,4), M (2,2), N (0,-3), S (-7,-1)

kumpel [21]

Given same lengths and slopes of the opposite sides and nature of the angle between adjacent sides, we have;

The type of quadrilateral is a parallelogram

<h3>How can the type of quadrilateral be found?</h3>

The given points are;

L(-5, 4), M(2, 2), N(0, -3), S(-7, -1)

Lengths of the sides are;

Length of LM = √((2-(-5))²+(2-4)²) ≈ √(53)

Length of MN = √((2-0)²+(2-(-3))²) ≈ √(29)

Length of NS = √((0-(-7))²+((-3)-(-1))²) ≈ √(53)

Length of LS = √(((-7)-(-5))²+((-1)-4)²) ≈ √(29)

Therefore;

The lengths of opposite sides are the same.

Slope of LM = (2-4)/(2-(-5)) = -2/7

Slope of MN = (2-(-3))/(0-2) = 5/2

Slope of NS = ((-3)-(-1))/(0-(-7)) = -2/7

Slope of LS = ((-1)-4)/(-7-(-5)) = 5/2

Therefore;

The opposite sides are parallel, and

The the adjacent sides are not perpendicular

The quadrilateral created by the points L(-5, 4), M(2, 2), N(0, -3), S(-7, -1) is therefore;

A parallelogram

Please help me.. im stuck

Answer: x = 2/3 and y = 2/3

Step-by-step explanation:

I've attached the solution.

From the solution, you get y = -5x + 4 and

y = x.

Now,

Put y = x in y = -5x + 4.

x = -5x + 4

6x = 4

x = 4/6

x = 2/3

So, y = 2/3 because y = x.

What is the surface area?

torisob [31]

Answer:

since the formula of a triangle is ab/2 and since there is four simply multiply 3x4 which is 12 and divide by 2 which is 6 and 6x4= 24 and add that tp 9 since the base is just 3x3 which results for an answer of 33.

Salim has 5 boxes of paint jars. Each box has the same number of paint jars. His teacher gives him 6 more paint jars. Now he has

olchik [2.2K]

Answer:

7 jars per box

Step-by-step explanation:

He now has 41 jars. How many did he have before his teacher gave him 6?

Well, 41-6=35. He had 35 jars before his teacher gave him more.

It says there was an equal amount of jars in each box. There are 5 boxes. Divide the total amount of jars (35) by the amount of boxes to find out how many jars are in each box.

35 jars / 5 boxes = 7 jars / box

Marie has a small copy of rene magritte's famous painting, the schoolmaster. Her copy has dimensions 2 inches by 1.5 inches. The

Andrej [43]

We just multiply the scale to the dimensions
2 in to original is: 2×40= 80 cm
or do proportions:
$\frac{2}{x}$ = $\frac{1}{40}$
= $\frac{2*40}{1}$ =x
=80 cm=x the original dimension.
Same thing to the other side.
1.5×40=60 cm
or proportions again:
$\frac{1.5}{y}$ = $\frac{1}{40}$
$\frac{1.5*40}{1}$ =y
60 cm=y
60 cm is the original dimension
80 cm times 60 cm ORIGINAL DIMENSION
