Find the coordinates of the other endpoint of the​ segment, given its midpoint and one endpoint.​ (Hint: Let​ (x,y) be the unknown endpoint. Apply the midpoint​ formula, and solve the two equations for x and​ y.)
midpoint ​(20​,21​), endpoint ​(19​,​12)

Step-by-step explanation:

well, the starting equation and the target format have been given.

let's do the multiplications and compare the target with the starting information.

from there we see what is different or missing.

x² + 14x + 13 = 0

and

(x - p)² = q

x² - 2px + p² = q

x² - 2px + (p² - q) = 0

now let's compare the different parts :

x² = x²

-2px = 14x

-2p = 14

p = -7

p² - q = 13

-7² - q = 13

49 - q = 13

36 - q = 0

q = 36

so, the square (x - p)² = (x + 7)² is completed when

x² + 14x + 49 = 0

but we have only "+ 13". so we need to add 36 to get 49. but we need to do it on both sides, to keep the equation true :

x² + 14x + 13 + 36 = 36

x² + 14x + 49 = 36

(x + 7)² = 36

just as we calculated already above.

and now this can be solved by pulling the square root on both sides (a quadratic equation has always 2 solutions)

x + 7 = ±6

x1 = 6 - 7 = -1

x2 = -6 - 7 = -13

Points A, C, and C also form a triangle.

The equation of line is y= -1/4x  + 2

The slope of the line and a point on the line can be used to create the equation of a line. To better comprehend how the equation for a line is formed. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis.

The general form is [tex](y- y_1)= m(x - x_1)[/tex]

given:

line that is perpendicular to y = 4x + 8 and passes through (−8, 4).

Here the slope of given line is 4.

So, the slope of perpendicular lines is

m = -1/4

Now, as the line passes through (-8, 4)

Then using

(y - y1) = m (x- x1)

y- 4= -1/4(x- (-8))

y-4 = -1/4 ( x+8)

y-4 = -1/4 x - 2

y= -1/4x  + 2

Hence, the equation of line is y= -1/4x  + 2.

The mass of the biscuit and fruit are 20 and 64 grams respectively.

A ratio indicates how many times one number contains another.

Therefore, the ratio of fruits and biscuit the zoo fed the monkeys is 7:5.

let's find the total number of the items.

Hence, using the table and ratio,

number of fruits = 7 / 12 × x

number of fruits = 28

Therefore,

28 = 7x / 12

cross multiply

12 × 28 = 7x

336 = 7x

divide both sides by 7

336 / 7 = 7x / 7

x = 48

Hence,

mass of biscuit = 5 / 12 × 48

mass of biscuit = 20

The second missing value of the table,

mass of biscuit = 5 / 12 × x

45 = 5x / 12

5x = 504

x = 504 / 5

x = 108

Hence,

mass of fruit = 7 / 12 × 108

mass of fruit = 756 / 12

mass of fruit = 63

Therefore, the mass of the biscuit and fruit are 20 and 64 grams respectively.

There are 3 whole number with different values of x.

All positive integers from 0 to infinity are included in the group of numbers known as whole numbers. The number line has these numbers. They are all genuine numbers as a result. Although not all real numbers are whole numbers, we may argue that all whole numbers are real numbers. As a result, the set of natural numbers plus zero may be used to define whole numbers. The category of whole numbers and the negative of natural numbers is known as integers. Thus, integers can be either positive or negative, including 0. Natural numbers, whole numbers, integers, and fractions all fall under the category of real numbers.

Whole numbers refer to all natural numbers, including '0,' in their entirety. Examples include: 0, 11,1,2,3,4 etc

As stated in the question,

Then, in order to determine which values of "x" the given fraction is a square for, we must first locate them.

We are aware that the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.

The equation of the perpendicular bisector of the line segment whose endpoints are (-8,-1) and (-4,5) is y = 3/2x + 7

First we have to find the midpoint of the line

endpoints are (-8,-1) and (-4,5).

midpoint = -8 + -4/2 , -1 +5/2

= -6, 2

slope = -1 - 5 / -8 - -4

= -6 /-4

= 3 / 2

Equation for the line

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

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

y = 3/2x + 7

Hence the equation of the perpendicular bisector of the line segment whose endpoints are (-8,-1) and (-4,5) is y = 3/2x + 7

The width of the photo on the cake is x.

The dimensional relationship mentioned between the dimensions of the cake & the photo on the cake mentioned in the question are:

Width of cake = Width of photo + 4 inches

i.e., W = x + 4

And, Length of the Cake is twice the Width of the cake

i.e., L = 2*W

Also, It is mentioned that the Area of the Cake is 254 sq inches.

We know Formula to calculate the Area of a rectangle is :

          =>   Area = Length * Width

          =>   254  ≤ 2*W * (x+4)     =>   254 ≤ 2(x+4)*(x +4)

The probability of scoring a goal exactly 8 times by Jon is given by 0.0234. It is obtained using the prerequisite knowledge of binomial distribution and probability.

What is Binomial Distribution in Probability?

When each trial has a probability of occurring equally likely, then the number of trials or observations is outlined using the binomial distribution. The chance of observing a specific number of successful outcomes in a specific number of trials is determined by using the binomial distribution.

Calculation of the probability of the given event

Total no. of possible outcomes, n = 11

The probability that Jon will kick the ball in the net, p(x) = 0.4

The probability that Alex will kick the ball in the net, q(x) = 0.6

Using Binomial Distribution, we get,

P(x = r) = C(n,r) × (p)r × q(n - r)

where x is the score made by Joe

P(x = 8) = C(11,8) × (0.4)8 × (0.6)3

             = 0.0234

Hence, the probability that Jon will score exactly 8 times is 0.0234.

Answer:

4.12

Step-by-step explanation:

Step-by-step explanation:

what do you mean by "rule" ?

the line equation (in slope-intercept form ? or any other ?) ?

or only the slope of the line ?

I assume you need the slope-intercept line equation.

this looks like

y = ax + b

"a" is the slope of the line, "b" is the y-intercept (the y value when x = 0).

"b" we know already from the specified intercept points : 5.5

the slope of a line is simply the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

and the axis-intercept points are points on the line too. so, we can use them.

so, we see

x changes by +3.667

(= 3 2/3 = 3×3/3 + 2/3 = (3×3 + 2)/3 = 11/3)

from -3.667 to 0.

y changes by +5.5

(= 5 1/2 = 5×2/2 + 1/2 = (5×2 + 1)/2 = 11/2)

from 0 to 5.5

the slope is therefore

5.5 / 3.667 = 11/2 / 11/3 = 11/2 × 3/11 = 3×11 / 2×11 = 3/2

and so, the line equation is

y = 3/2 x + 5.5

or

y = 3/2 x + 11/2 = 1/2 × (3x + 11)
