The equation of a leftward parabola is [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]. Then the correct option is D.

It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called the focus, and the non-movable line is called the directrix.

The parabola is open to the left.

We know that the equation of the parabola will be in square form.

a.  [tex]\rm (x - 4)^2 = 4(y +3)[/tex]

This is an equation of an upward parabola.

b.  [tex]\rm (x - 4)^2 = -4(y+ 3)[/tex]

This is an equation of a downward parabola.

c.  [tex]\rm (y - 4)^2 = 4(x+ 3)[/tex]

This is an equation of a rightward parabola.

d.  [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]

This is an equation of a leftward parabola.

Thus, the correct option is D.

Answer:

122

Step-by-step explanation:

We are finding the difference, so our equation will be

[tex]82 - (-40)[/tex]

Subtracting by a negative is basically the same as adding. (- & - = +)

[tex]82 - (-40) =82 + 40[/tex]

Now add 82 + 40

Step-by-step explanation:

In the diagram, AB is adjacent to Angle"a", because if we don't consider hypotenuse, it is the only associated segment to the angle.

The segment opposite to the right angle is called Hypotenuse.

The last one, AC segment, is called the Opposite because it is the opposite to Angle"a".

If we look at it from AngleC, however, its Adjcent will be segment AC, and Opposite will be segment AB.

Answer:

5 cm

Step-by-step explanation:

Square has the formula = S × S

S × S = S²

S = Side

Square has an area 25 cm²

Length of a side of the square :

25 cm² = S²

S² = 25

S = √25

Answer:

104 m²

Step-by-step explanation:

Area of the quadrilateral

= width × length

= 10 m × 8 m

= 80 m²

Area of the triangle

= ½ × base × height

= ½ × 8 m × 6 m

= 24 m²

Total area of the shape

= Area of the quadrilateral + Area of the triangle

= 80 m² + 24 m²

= 104 m²

Answer:

1. False

2. False

Step-by-step explanation:

The statement "BC and B'C' are on the same line" is false, and the statement "the lengths of CD and C'D' are equal" is false.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Quadrilateral A'B'C'D prime is the result of dilating quadrilateral ABCD about point P by a scale factor of 5/3

To determine whether each claim about the properties of ABCD and A'B'C'D' is true or false.

The points in the image by multiplying the coordinates of the points in the preimage by the scale factor.

Thus, the statement "BC and B'C' are on the same line" is false and the statement "the lengths of CD and C'D' are equal" is false.

Refer to:

https://brainly.com/question/23826439

184.6cm³ up you are rounding to the nearest tenth 184.56cm³ if you are rounding to the nearest hundredth

It's a hemisphere instead of a sphere so the formula is 2/3×π×r³ which gives us the equation of 2/3×π×4.45³ snd the reason we use 4.45 is because the diameter is 8.9 so we have to divide that by 2 to get the radius which is 4.45

Answer:

(-4, 2)

Step-by-step explanation:

4x+2y=-12

3x+y=-10

Start by dividing the first equation by 2 to simplify it...

2x+y=-6

Then, subtract -2x from both sides to isolate y...

y=-2x-6

Substitute -2x-6 for y in the second equation...

3x-2x-6=-10

Combine like terms...

x-6=-10

Add 6 to both sides

x-6+6=-10+6

x=-4

Plug -4 in for x to solve for y:

3(-4)+y=-10

-12+y=-10

Add 12 to both sides

-12+12+y=-10+12

y=2

(x,y)=(-4,2)

Answer:

Length will be 46 ft and width will be 16 ft

Explanation:

Let the width be x.

then the length will be 3x - 2

using the rectangle perimeter formula:

2( length + width )

2(x + 3x-2) = 124

2(4x-2) = 124

8x - 4 = 124

8x = 128

x = 16 ft

Width will be 16 ft and

Length: 3x - 2

           : 3(16)-2

           : 46 ft

The answer will be -5a-4

Step-by-step explanation:

Subtract 7a-12a=-5a

Add -8+4=-4

which makes the answer -5a-4

Hope this helps:)

Answer:

a = -4/5

Step-by-step explanation:

7a - 8 - 12a + 4

First, you want to put like terms together. You can rearrange the terms because of the Commutative Property.

7a - 12a - 8 + 4

I will put parentheses around the negative numbers, so it is easier to see the negative numbers.

7a (- 12a)( - 8) + 4

Now you combine the Like Terms

7a-12a     and     -8+4

- 5a - 4

Now you need to get the term with a all by itself on the other side of the equals sign. You can do this by adding the term over to the other side.

-5a - 4

+5a       +5a

Now you have

- 4 = 5a

To get the final answer you need to get a all by itself. You can do this by dividing 5 on both sides.

-4/5=5a/5

So you get

-4/5 = a

as your final answer.

Answer:

1.

[tex]y=\frac{1}{4}x+2[/tex]

m= [tex]\frac{1}{4}[/tex]

b= 2

2.

[tex]y=-\frac{1}{3}x+1[/tex]

m= [tex]-\frac{1}{3}[/tex]

b= 1

3.

[tex]y=3x+4[/tex]

m= 3

b=4

Step-by-step explanation:

1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.

The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=\frac{1}{4}x+2[/tex]

2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.

The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that    [tex]y=-\frac{1}{3}x+1[/tex]

3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.

The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that  [tex]y=3x+4[/tex]

∑ Hey, irisraya1 ⊃

Answer:

No.

Step-by-step explanation:

Given:

[tex]\frac{8}{24}=\frac{2}{63}[/tex]

Solution:

We can cross multiply to see if this proportion works.

[tex]63\times8=504[/tex]

[tex]24\times2=48[/tex]

[tex]48\neq 504[/tex]

As we can see, 48 and 504 does not equal.

Hence, this proportion doesn't work.
