What is the range of y=−x2−6x+1?

Answers

Answer 1

Answer:

All real numbers / (-∞, ∞) / R

Step-by-step explanation:

The equasion provided is a linear equasion meaning it can be written in the y=ax+b format, where both a and b are real numbers. All linear eqasions have a range of all real numbers, you can write this using the three solutions provided.

You can solve this two ways, number one would be to put this in a graphing calculator and number two would be reducing the equasion to the y=ax+b format.

Method 1:

look at image provided. The app is PhotoMath.

Method 2:

Write the equasion:

y = -2x - 6x + 1

Collect like terms:

y = -8x + 1

This now proves that the equasion is linear becuase you can write it in the y=ax+b format. a being -8 and b being 1.

The answer is 134.2 yards.

Explanation:

Question 7:
Let x yards be the diagonal of the fields.

120² + 60² = x²

14400 + 3600 = x²

18000 = x²

x² = 18000

x = √18000

Calculate the measures of spread for Mrs Hampton's class data. Justify your
response by describing the process used to find each measure, (2 points)

Answers

The measures of spread include the range, quartiles and the interquartile range, variance and standard deviation. Let's consider each one by one.

Interquartile Range:

Given the Data -> First Quartile = 2, Third Quartile = 5

Interquartile Range = 5 - 2 = 3

Range: 8 - 1 = 7

Variance:

We start by determining the mean,

[tex]\:1+\:2+\:3+\:3+\:3+\:5+\:8 / 7 = 3.57[/tex]

n = number of numbers in the set

Solving for the sum of squares is a long process, so I will skip over that portion and go right into solving for the variance.

[tex]\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n-1},\\\\=> SS/n - 1\\\\=> 31.714/7 - 1\\=> 5.28571[/tex]

5.3

Standard Deviation

We take the square root of the variance,

[tex]\sqrt{5.28571} = 2.29906[/tex]

2.3

If you are not familiar with variance and standard deviation, just leave it.

Find the equation of the line through point (−2,−1) and perpendicular to 5x+6y=−6.

Answers

Step-by-step explanation:

When lines are perpendicular to each other

multiplying their gradients(m) will equal to - 1

so , m1 × m2 = -1

1st:Find m1

5x+6y= -6

make y the subject,

6y= -5x -6

[tex]y = \frac{ - 5x - 6}{6} [/tex]

y= -5/6x - 1

because y = mx + c

m1 = -5/6

2nd:find m2

-5/6 × m2 = -1

m2 = 6/5

3rd: substitute m2 and the coordinates into y=mx+c

y=mx+c

-1= (6/5)(-2)+c

-1 = -12/5 + c

-5 = -12 + c

-5+12= c

c = 7

4th: substitute m2 and c into y= mx+c to find the equation the line

y =6/5x + 7 (Ans)

As per slope-intercept form, the equation of the line through point (−2,−1) and perpendicular to 5x + 6y = -6 is 5y = 6x + 7.

What is the slope-intercept form of a straight line?

The slope-intercept form of a straight line is y = mx + c.

Here, 'm' is the slope and 'c' ix the y-intercept of the given line.

The given equation is 5x + 6y = - 6

Therefore, in slope-intercept form, this equation will be:

y = - 5x/6 - 1

Therefore, the slope of this line is m = - 5/6 and the y-intercept is c = - 1.

The required line is perpendicular to the given line.

Therefore, the slope of the required line is

= - 1/m

= 6/5

Again, the required line passes through the point (- 2, - 1).

Therefore, - 1 = - 2(6/5) + c

⇒ c = - 1 + 12/5

⇒ c = 7/5

The equation of the required line is

y = (6/5)x + 7/5

⇒ 5y = 6x + 7

Consider the following system of linear equations:

4x – 6y = 12

Answers

Answer:

x=3, y=0

Step-by-step explanation:

Answer:

(3, 0 )

Step-by-step explanation:

Given the 2 equations

2x + 2y = 6 → (1)

4x - 6y = 12 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the x- term

- 4x - 4y = - 12 → (3)

Add (2) and (3) term by term to eliminate x

0 - 10y = 0

- 10y = 0 ⇒ y = 0

Substitute y = 0 into either of the 2 equations and solve for y

Substituting into (1)

2x + 2(0) = 6

2x = 6 ( divide both sides by 2 )

x = 3

solution is (3, 0 )

The value of x is an integer less than zero, and the value of y is an integer greater than zero. D. The value of x is a square root that can be simplified to an integer, and the value of y is an integer less than zero.

Answer:

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers. This should help you.

Step-by-step explanation:

The statement describes values of x and y such that could be an irrational numbers, the value of x is the square root of an integer, and the value of y is an integer greater than zero.

We have given that the value of x and y,

such that could be an irrational number.

What is irrational numbers?

An irrational number, any real number that cannot be expressed as the quotient of two integers.

Negative integers, or numbers below zero, are still whole numbers- just not positive whole numbers.

Therefore we can conclude that

The statement A, C, or D do not show the irrational numbers

because they all are stated as integers,

which cannot be irrational.

Therefore option B is correct.

The value of x is the square root of an integer, and the value of y is an integer greater than zero.
