Step-by-step explanation:

The equation of the scatter plot is y = 5/3x + 2 and the tree will be 18.7 feet in ten years

Linear equations are equations that have constant average rates of change.

Note that the constant average rates of change can also be regarded as the slope or the gradient

The information that completes the question is added as an attachment

From the scatter plot, we have the following points

(x, y) = (0, 2) and (6, 12)

The equation of the line is calculated as

y = (y2 - y1)/(x2 - x1) * (x - x1) + y1

Substitute the known values in the above equation

So, we have

y = (12 - 2)/(6 - 0) * (x - 0) + 2

So, we have

y = 5/3x + 2

In ten years, the value of x is

x = 10

So, we have

y = 5/3 x 10 + 2

Evaluate

y = 18.7

Hence, the height of the tree is 18.7 feet

We may determine the value of candy costs by solving a linear equation in which the answer is given as

x = $4.00.

We are aware that a shop owner blends two pounds of candy priced at x dollars per pound with three pounds of candy priced at $1.50 per pound. She asks $2.50 for the mixture.

Since the entire cost at the start must equal the total cost at the end, we can express the equation as 2lb + 3lb = 5lb.

2*x + 3*$1.50 = 5*$2.50

This linear equation for x may now be solved:

2*x = 5*$2.50 - 3*$1.50 = $8.00

x = $8.00/2 = $4.00

The sweet has a $4 price tag.

Step-by-step explanation:

The cost of each lemon meringue pie is $7.5 and the cost of each blueberry pie is $4.5.

Given that, Estelle and Carlos will be hosting a party and will buy 6 pies for their guests.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the cost of lemon meringue pies be L and the cost of blueberry pies be B.

Now, 2L = 4B - 3 and 3L= 3B + 9

Multiply the equation 2L = 4B - 3 by 3

6L = 12B - 9 --------(I)

Multiply the equation 3L= 3B + 9 by -2

-6L = -6B - 18 --------(II)

Add equation (I) and (II)

6L+(-6L) = 12B - 9 + (-6B-18)

⇒ 0 = 6B - 27

⇒ 6B = 27

⇒ B = $4.5

So, cost of lemon meringue = 2L = 4×4.5 - 3

⇒ 2L = 18 - 3

⇒ 2L = 15

⇒ L = $7.5

Therefore, the cost of each lemon meringue pie is $7.5 and the cost of each blueberry pie is $4.5.

Given:

Required:

We need to find f(b).

Explanation:

Replace x =b in the given equation to find the value of f(b).

Final answer:

(x - 2)² = 25

24 = x² - 4x + 3

rewritting:

x² - 4x = 24 - 3

x² - 4x = 21

using the completing the square:

coefficient of x = -4

square half the coefficient of x = (-4/2)² = (-2)²

Add the square half the cofficient of x to both sides of the equation

x² - 4x + (-2)² = 21 + (-2)²

taking out -4x:

(x - 2)² = 21 + 4

(x - 2)² = 25

The equation above is in the form (x + c)^2 = d or (x – c)^2 = d

Slope intercept equation is y = -4x - 17

The point (-6, 7) is on the graph of the line.

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

Explanation:

Let's solve for y

y - 7 = -4(x+6)

y - 7 = -4x - 24

y = -4x - 24 + 7

y = -4x - 17

It is now in slope intercept form y = mx+b

m = -4 = slope

b = -17 = y intercept

---------------

Compare the equation y - 7 = -4(x+6) with the point-slope form of y-y1 = m(x-x1)

The (x1,y1) is a point the line goes through.

Rewriting x+6 into x-(-6) has us get y - 7 = -4(x-(-6))

We can see that x1 = -6 and y1 = 7

Therefore, the point (x1,y1) = (-6,7) is on the line.

y=-1/3-4

Step-by-step explanation:

point slope form!

y-y=m(x-x)

with the point (-6,-2) and the slope (-1/3) replace the 2nd variables of each variable and replace m with the slope

y-(-2)=-1/3(x-(-6))

then solve that normally

y-(-2)=-1/3(x-(-6))

y+2=-1/3x -2

y=-1/3x-4

For a linear equation the solutions are on the line, while for inequalities the solutions are above or below the line (sometimes the line is also included).

When we have a linear equation of the form:

y = line

The solutions on the graph of this equation are the points on the line.

Now, for inequalities like:

y > line

or

y < line.

The solutions are all the points above (or below) the line itself.

Finally, for inequalities like:

y ≥ line

y ≤ line

The solutions are above (below) the line and the line itself.

The value of x is 4.

When two parallel lines are intersected by a transversal, the exterior angles created on either side of the transversal are equal, according to the alternate exterior angle theorem.

The given angles are 2x + 19° and x + 23°.

As these pair of angles are created on the outer side of the parallel lines but on the other side of the transversal, they are alternate exterior angles.

Using the Alternate Exterior Angles Theorem,

2x + 19° = x + 23°

2x - x = 23° - 19°

The intersection's two opposing corners are 91.40 feet apart.

Since the given data are:

Width of the Hillsboro Street = 73 feet

Width of Manchester Avenue = 55 feet

When Hillsboro Street and Manchester Avenue cross, calculate the distance between the intersection's two opposing corners,

Because the junction of Hillsboro Street and Manchester Avenue created a right-angled triangle:

Using Pythagoras's Theorem,

H² = B² + P²

H² = (55)² + (73)²

H² = 3025 + 5329

H² = 8354

H = √8354

H = 91.40

As a result, the distance between the intersection's two opposing corners is 91.40 feet.

Answer:

  4.  (d)

  5.  (b)

Step-by-step explanation:

You want to apply the secant and chord rules to the circles given in the diagram.

The secant rule is "the product of distances from the point of intersection of secants to the two points of intersection of the secant with the circle is the same for both secants." A tangent can be considered to be a secant that has both points of intersection with the circle in the same place.

The chord rule is similar to the secant rule: "The product of distances from the point of intersection of the chords to their intersection with the circle is the same for both chords."

The diagram shows a tangent of length 12, so the product of distances to the two points of intersection with the circle is 12(12).

The secant has length 8 to the near point of intersection, and (x+8) to the far point of intersection. That product is the same as for the tangent:

  8(x +8) = 12(12) . . . . . . matches choice D

One chord has lengths of 14 and x, so the product of those is 14x.

The other chord has lengths of 12 and 21, so the product of those is 12(21).

The product is the same for both chords, meaning ...

  14x = 12(21) . . . . . . matches choice B

Step-by-step explanation: 20 perrcent of 52

The unit price per ounce at Price-Club is $0.29 per ounce and the unit price per ounce at Shop Mart is $0.21 per ounce.

The unit price can be determined by dividing the total cost by the total ounce that is purchased.

Division is the process of putting a number into  equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. The result of the division process is known as the quotient. Other mathematical operations include addition, subtraction and multiplication.

Unit price = total cost / total ounce sold

Unit price of Price-Club = $3.44 / 12 = $0.29 per ounce

In order to determine the unit price of Shop Mart, pounds have to be converted to ounces

1 pound = 16 ounces

To convert 2 1/2 pounds to ounces, multiply 2 1/2 by 16. Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

16 x 2 1/2

16 x 5/2 = 40 ounces

Unit price of Shop Mart = $8.35 ÷ 40 = $0.21 per ounce
