Write an equation of the parabola shown.

a. x=3/28y²

b. x=7/12y²

Also please explain how you got the answer :)

Answer:

Step-by-step explanation:

Let's solve for a.

ax+3=6

Step 1: Add -3 to both sides.

ax+3+−3=6+−3

ax=3

Step 2: Divide both sides by x.

ax /x = 3 /x

a= 3 /x

Answer:

a= 3 /x

Answer:

ax = 3

Step-by-step explanation:

ax + 3 = 6

Subtract 3 from both sides of the equation

ax = 3

Answer:

3.84*10^-2 s the answer:)

Step-by-step explanation:

Answer:

The equation of the parabola is;

(y + 11)^2/120 = (x + 7)^2 + (y-5)^2

Step-by-step explanation:

Here, we are given the focus (-7,5) and the directix y = -11

We proceed to find the equation of the parabola

That would be in the form;

(y- mx - b)^2 /m^2 + 1 = (x- h)^2 + (y-k)^2

Let’s write the directix in the form y = mx + b

This shows that m = 0 and b = -11

Also h = -7 and k = 5

So let’s substitute;

(y + 11)^2 /(-11^2 + 1) = (x+7)^2 + (y-5)^2

= (y + 11)^2/120 = (x + 7)^2 + (y-5)^2

Answer:

★ The answer is down BELOW

EQUATION : (y + 11)^2/120 = (x + 7)^2 + (y-5)^2

Answer:14:06

Step-by-step explanation:

Because because 10 percent of 12.78 is 1.28 then 1.28 + 12.78 = 14.06 so 14.06 is your answer

Answer:

The equation of the line is 6y = 7x + 23

Step-by-step explanation:

We begin by calculating the slope of the line;

mathematically, the slope is given by;

m = (y2-y1)/(x2-x1)

That would be;

m= (5-(-2))/(1-(-5))

m = 7/6

So the equation becomes;

y = 7/6x + b

We below need to get the value of the y-intercept b

We get this by making a substitution for any of the two points

Let’s say we make the substitution for (-5,-2) in which case y = -2 and x = -5

Thus, we have

-2 = 7/6(-5) + b

-2 = -35/6 + b

b = -2 + 35/6

b = (-12+ 35)/6 = 23/6

So we have;

y = 7/6x + 23/6

let’s multiply through by 6

6y = 7x + 23

Answer:

The value of x is 2yw + y - 1

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

The function is defined as mathematics expression defines a relationship between one variable and another variable. When we say that a variable quantity y is a function of a variable quantity x, we indicate that y depends on x and that  value of x determines what value of  y  will be. This relationship can be expressed as follows: y = f (x)

Given the equation as:

(2x + 2)/y = 4w + 2

To determine the value of x

Multiply by y both sides

y × (2x + 2)/y = (4w + 2) × y

2x + 2 = 4wy + 2y

Subtract 2 from both sides

2x + 2 - 2 = 4wy + 2y - 2

2x = 4wy + 2y - 2

Divide by 2 both sides

x = (4wy + 2y - 2)/2

x =  4wy/2 +  2y/2 - 2/2

x = 2yw + y - 1

Hence, the value of x is 2yw + y - 1.

Answer:

Step-by-step explanation:

Check the attachment for the diagram.

You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;

tan 35° = opposite/adjacent

tan 35° = AB/BC

tan 35° = AB/100

AB = 100tan35°

AB = 100 * 0.7002

AB = 70.02m

Hence the distance across a lake between A and B is approximately 70m

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:(6,14)

Step-by-step explanation: x+y≤22   &   .05+.10y≥ 1.40

y≤22-x                                                        y≥14- 1/2x

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Anna has a nickels and y dimes. She has at most 22 coins worth a minimum of $1.40 combined.

Let x be the number of nickels and y be the number of dimes. Then the equation is given as,

0.05x + 0.10y ≥ 1.40

x + y ≤ 22

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.
