Answers

Answer:

[tex]\frac{ (x+3)^2}{9} + \frac{ (y-2)^2}{4} =1[/tex]

-step explanation:

The standard form of the given equation was reduced, representing an ellipse.

The given equation is:

[tex]4x^{2} +9y^{2} +24x-36y+36=0[/tex]

What is an equation?

An equation is a statement that equates to two expressions.

We know the above equation represents an ellipse.

Rearranging the given equation

[tex]4x^{2} +24x+9y^{2} -36y+36=0[/tex]

[tex]4(x^2+6x)+9(y^{2} -4y)+36=0[/tex]

[tex]4(x^2+6x+9)+9(y^{2} -4y+4)=36[/tex]

[tex]4(x+3)^2+9(y-2)^2=36[/tex]

[tex]\frac{4(x+3)^2}{36}+\frac{9(y-2)^2}{36} =1[/tex]

[tex]\frac{(x+3)^2}{9}+\frac{(y-2)^2}{4} =1[/tex], which is the standard form of the given equation.

Hence, the standard form of the given equation was reduced.

What is the slope of the line that contains these points?

Answers

The slope can be found with two sets of points

The points can be any points, but in this case I choose the point (-1,10) and (1,2)

Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{10-2}{-1-1} =\frac{8}{-2} =-4[/tex]

The slope of the line that contains these points is -4.

Write an equation for the line in slope-intercept form.

Answers

Answer:

y=2x+2

Step-by-step explanation:

the equation for slope intercept form is y=mx+b where b is the y intercept and m is the slope. From the graph we can see that where x is 0 y is 2 which makes 2 be the y intercept, and when x is 1 y is 4 which then you replace y for 4 and x for 1 which would be 4=m(1)+2,now u subtract 2 from both sides which leaves you with 2=m(1) and m times 1 is m so now your left with 2=m which means the slop is 2

Rolling a 3 or rolling an odd number on a six sided die. Is it mutually exclusive or non-mutually exclusive? Give one reason.

Answers

Answer:

Non-mutually exclusive

Step-by-step explanation:

both events can happen simultaneously... 3 is an odd number, events A and B  have a common outcome.

It would be mutually exclusive if event A was rolling a 4 and event B was rolling an odd number.

Answer: Non-Mutually Exclusive

===================================================

Explanation:

Ask yourself "is it possible to get a 3 and an odd number at the same time?"

The answer is "yes, because 3 is an odd number"

This is why they are non-mutually exclusive.

Mutually exclusive events cannot happen at the same time. In terms of a venn diagram, mutually exclusive events would be represented by two circles that do not overlap. The overlapping region is where the two events happen at the same time. An example of mutually exclusive events would be flipping a single coin to land on heads and tails at the same time.

A system of linear equations is given by these equations 3y-2x=-9 y=-2x+5 The solution to this system is

Answers

Answer:

(3, -1) or x=3, y=-1

Step-by-step explanation:

using substitution for y, the first equation becomes 3(-2x + 5) - 2x = -9

distribution of the 3 gets your equation to be -6x + 15 - 2x = -9

from here you combine like terms to get -8x + 15 = -9

from here it's just a two step equation

subtract 15 from both side to get -8x = -24

divide and get x = 3

substitute x in the equation for y to get y = -2(3) + 5

distribution gets you y = -6 + 5, which makes y = -1

to check your work you can just plug in the variables equivalents in the first equation, which upon doing you can see that the answer is indeed 3, -1

A student adds 10 grams of four different powdered solids into four different beakers. The student then adds 100 mL of water to each beaker, stirs the mixtures, and allows them to sit for half an hour before recording observations. Which question is the student most likely trying to answer with this investigation?

Answers

Answer:

Which substance dissolves in water?

Step-by-step explanation:

The student adds the same amount of substance of different types i.e., 10 grams to each beaker and the same amount of water i.e., 100 mL to each beaker. All of them are stirred and observations are taken down at the end of thirty minutes.

That is all that is mentioned in the question. The student is most likely measuring which substance dissolves in water. As all the other variables are kept constant.

So, the student here is most likely trying to answer the question "Which substance dissolves in water?"

The perimeter of a rectangle is 40 units. The length of the rectangle, L, is 7 units.

Answers

Answer:

L=7

W=13

Perimeter=40

Area=91

Step-by-step explanation:

Perimeter = 2L+2W

40=2(7)+2W

40=14+2W

-14  -14

26=2W

Divide both sides by 2

13=W

Area=L x W

7 x 13 = 91

Answer:

length = 7 units

width = 13 units

area = 91  square units

perimeter = 40 units

Step-by-step explanation:

What is the area of a rectangle?

  ❖ The area of a rectangle can be found by multiplying the length and

       width of the rectangle.

What is the perimeter of a rectangle?

  ❖ The perimeter of a rectangle is the sum of all sides- length and

       width. In this case, we're given the perimeter as 40 units and the

       length as 7 units, but the width is unknown. Formula to find

       perimeter of rectangle is 2(l + w) = P.

Solving for Width

[tex]40=2(7+w)[/tex] [tex]40=14+2w[/tex] [tex]26=2w[/tex] [tex]w=13[/tex]

Solving for Area
