Find the midpoint of (-5,12) and (3,-6)

Answer:

x = 6, and x = 1

Step-by-step explanation:

If each expression equals y, the simplest approach would be to equate them;

x^2 - 5x + 7 = 2x + 1 => Isolate all the terms on one side

x^2 - 5x - 2x + 7 - 1 = 0 => Combine like terms

x^2 - 7x + 6 = 0 => solve using quadratic equation

x = ( - (- 7) + √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1

= 7 + √25 / 2 = 7 + 5 / 2

= 6

x =  ( - (- 7) - √( - 7)^2 - 4 * 1 * 6 )/ 2 * 1

= 7 - √25 / 2 = 7 - 5 / 2

= 2 / 2 = 1

Answer:

4. Given that the distance from one place to another are placed in ranges of a thousand, then the distances from Sao Paulo to Chicago Illinois which is 5,252 miles and from Chicago Illinois to Istanbul Turkey which is 5,784 miles will be in the same 5,000 kilometer distance range and both distances will taken as the same distance

The same situation can also be arrived at by rounding down both distances

Step-by-step explanation:

The given information are;

The flight distances given;

From Sao Paulo to Chicago Illinois = 5,252 miles

From Chicago Illinois to Istanbul Turkey = 5,784 miles

From Beijing China to Chicago Illinois = 6,579 miles

Lees conjectured the flight distance from Chicago to Istanbul is the same as the flight distance from Chicago Sao Paulo when the distances are rounded to the nearest thousand

Placing the distances in ranges of 1000, we have the 5,252 miles and the 5,784 miles will be in the same 5,000 to 5,999 miles range.

The distance we have to hike to reach the top of the mountain is

2.92 miles.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

Given, A mountain has a 20-degree slope and is 1 mile tall and we have to hike the mountain so we want to know the distance.

Here hypotenuse is the distance we have to hike and according to the reference, the angle opposite has a distance of 1 mile.

We know sin = opposite/hypotenuse.

sin20° = 1/hypotenuse.

0.342 = 1/hypotenuse.

hypotenuse = 1/0.342.

hypotenuse = 2.92 miles.

Answer:

w = 1

Step-by-step explanation:

If the slope is 0, then this line will be horizontal.

This means that the y value will be the same for all points on the line.

Since we are given the point (3, 1), we know that the y value is 1. This means all other points on the line will have 1 as the y value.

So, w is equal to 1 because it is the y value in that ordered pair.

Answer:

2. the answer is 5 because the square of 5 is 25 and 4 x 25 = 100 which is 20 x 5

Step-by-step explanation:

We are required to find the unknown number from the expression

2.

let

the number = x

four times the square of a number equals 20 times that number

4x² = 20x

Divide both sides by 4x

x = 5

The number is 5

3.

let

x = the unknown number

Twice the square of the sum of a number and 3 is 98

sum of a number and 3 = x + 3

square of the sum = (x+3)²

Twice the square = 2(x + 3)²

2(x + 3)² = 98

2(x² + 6x + 9) = 98

2x² + 12x + 18 = 98

2x² + 12x +18 - 98 = 0

2x² + 12x - 80 = 0

x² + 6x - 40 = 0

using factorization method to solve the quadratic equation

x² + 10x - 4x - 40 = 0

x(x + 10) - 4(x + 10) = 0

(x + 10) ( x - 4) = 0

x + 10 = 0 or x - 4 = 0

x = -10 or x = 4

Therefore, the unknown number is -10 or 4

First, since ¨in debt¨ is describing negative value, all of the expressions that have positive 225 is incorrect. Also, since the term ¨triple¨ is describing multiplcation, any expression that does not have multiplication is also incorrect.

Step-by-step explanation:

Given the equation, [tex] s = 1.7f - 7.2 [/tex],

where,

s = shoe size,

f = foot length,

To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.

[tex] s = 1.7f - 7.2 [/tex]

[tex] s = 1.7(9) - 7.2 [/tex] (substitution)

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 8.1 [/tex]

Answer:

1/3

Step-by-step explanation:

If you want to write the fraction in its lowest terms, all you have to do is simplify!! Simplifying is easy; all you have to do is divide on the top and bottom of the fraction by the same number.

So, to simplify 6/18, figure out what the highest number is that can go into both numbers in the fraction. For this problem, the highest number is 6.

6 divided by 6 is 1.

18 divided by 6 is 3.

The simplified answer comes out as 1/3...you can also check it by multiplying 1 and 3 by 6.

1 multiplied by 6 is 6.

3 multiplied by 6 is 18.

So, 6/18 in lowest terms is 1/3!!
