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:

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.

Based on IRS regulations, the taxes withheld for a single person with 2 withholding allowances making $799 per period is C. $53.

IRS regulations in 2005 stated that when a person who is making at least $780 per payroll period, but not more than $800, and had 2 withholding allowances, they would have taxes withheld of $53.

The single person in this scenario is making $799 which falls into the above bracket so they will have taxes withheld of $53.

In conclusion, option C is correct.

The volume of the hemisphere is 1,475.73cm^3.

Step-by-step explanation:

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

Step-by-step explanation:

Use the Distributive Property in order to solve.

Distributive Example:[tex]a(b+c)=ab+ac[/tex]

Using the property into the equation:

[tex]3(3y-9)=3(3y)-3(9)=9y-27[/tex]

[tex]9y-27=0[/tex]

Add 27 to both sides:

[tex]9y=27[/tex]

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

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]

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:

-10x+7.5

Step-by-step explanation:

Sorry if wrong!

Step-by-step explanation:

when 2 shapes are similar, it means that all their angles are the same compared with each other.

and all distances (incl. side lengths) if one shape correlate to the corresponding distances in the other shadow by the same ratio or factor.

we have one side (30 m in A and 50 m in B), where we have both measures.

we see that the ratio to "go" from A to B is 30/50 = 3/5.

that means a distance in A is the same distance in B multiplied by 3/5.

and that factor is the same also for every other side.

therefore,

x = 15 m × 3/5 = 3 m × 3 = 9 m

y × 3/5 = 18 m

3y = 90 m

y = 30 m

Answer:

y = 2x + 5

Step-by-step explanation:

Slope-intercept form: y = mx + b

where:

Given: a line with a slope of 2, and y-intercept of 5

Equation: y = 2x + 5

Randomly select y-values that will help you graph the equation:

when y = -9:

-9 = 2x + 5 [subtract 5 from both sides]

-9 - 5 = 2x

-14 = 2x [divide both sides by 2]

-14 ÷ 2 = 2x ÷ 2

-7 = x

coordinate: (-7, -9)

when y = -5:

-5 = 2x + 5 [subtract 5 from both sides]

-5 - 5 = 2x

-10 = 2x [divide both sides by 2]

-10 ÷ 2 = 2x ÷ 2

-5 = x

coordinate: (-5, -5)

when y = -1:

-1 = 2x + 5 [subtract 5 from both sides]

-1 - 5 = 2x

-6 = 2x [divide both sides by 2]

-6 ÷ 2 = 2x ÷ 2

-3 = x

coordinate: (-3, -1)

when y = 3:

3 = 2x + 5 [subtract 5 from both sides]

3 - 5 = 2x

-2 = 2x [divide both sides by 2]

-2 ÷ 2 = 2x ÷ 2

-1 = x

coordinate: (-1, 3)

With these coordinates, graph them on a coordinate plane and draw a straight line through them. That should be the graph of the equation.

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.
