The Nature of Roots Of a Quadratic Equation help me with these pls

Answers

Problem 1

Answers:

Real = sqrt(49), 5/6, 12.5, 8/12, 225, sqrt(24)/16, sqrt(32)

Not real = sqrt(-20) and sqrt(-16)/9

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

Explanation:

Anything involving a square root of a negative number will result in a non-real answer. Anything else is real.

Traditionally y = sqrt(x) has a domain of nonnegative numbers. If x >= 0, then y is some real number. If x < 0, then we'll need to use the imaginary number i = sqrt(-1).

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

Problem 2

Answers:

Rational = sqrt(49), 5/8, 12.5, 8/12, and 225

Irrational = sqrt(24)/16, sqrt(32)

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

Explanation:

Ignore the non-real numbers. Focus solely on the real values.

A rational number is where we can write it as a ratio of two integers. An example is 5/8 since 5 and 8 are integers. The denominator can never be zero.

Decimal values that terminate can be written as a fraction. For instance, 12.5 = 125/10.

Square roots of perfect squares are also rational. For example sqrt(49) = 7 = 7/1

Something like sqrt(32) is not rational because we can't write it in the form p/q with p,q being integers. We say it is irrational.

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

Problem 3

Answers:

Perfect Squares = 225

Non-perfect squares = everything else

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

Explanation:

A perfect square is of the form x^2, where x is a positive integer.

The only perfect square listed is 225 because 225 = 15^2. Here x = 15.

Note: a perfect square is an integer itself.

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

Problem 4

As discussed earlier, rational numbers are fractions of integers. So we have something of the form p/q where p,q are integers and q is nonzero. An example of a rational number is p/q = 7/8 with p = 7 and q = 8.

Irrational numbers are ones that cannot be written as p/q. A famous example of an irrational number is pi = 3.14, but we could do something like sqrt(17) for instance as well. The stuff under the square root must be a non-perfect square.

Perfect squares are integers in the form x^2, with x being an integer also. A visual way to think of perfect squares is to think of a square with side length x, so its area is x^2. If x = 9, then its area is x^2 = 9^2 = 81, so 81 is a perfect square. We only consider whole number side lengths.

What is the answer to the question
1.5(q-4)-2=4
Thank you so much for answering!

Answers

Answer:

q= 8

Step-by-step explanation:

1.5q-6-2=4

1.5q-8=4

1.5q=4+8

1.5q+4+8= 12

divide both sides

1.5q=12=8

Write an equation of the line with a slope of -3/4 and y-intercept of -6

Answers

Answer:

Hi there!

Your answer is:

y= -3/4x -6

Step-by-step explanation:

The y int is the constant.

The slope is the coefficient of the X

Hope this helps!

The equation of the line with a slope of -3/4 and y-intercept of -6 is; 4y + 3x = -24.

The slope-intercept form of the equation of a straight line usually takes the form;

y = Mx + c

where; m = slope and c = y-intercept

Therefore; the equation of the required line is;

y = (-3/4)x + (-6)

4y = -3x - 24

4y + 3x = -24

It takes 3 weeks to be the amount of Drew and Stacie same in the bank account.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Let's say it takes x week to be same the amount of Drew and Stacie.

Amount after x week of

Drew ⇒ 48 + 8x

Stacie ⇒ 87 - 5x

For to be it same,

48 + 8x = 87 - 5x

8x + 5x = 87 - 48

13x = 39

x = 3

Hence " It takes 3 weeks to be the amount of Drew and Stacie same in the bank account".

If 6x + 4 = 11x - 21, what is the value of x?

Answers

Answer:

x = 5

Step-by-step explanation:

11x - 6x = 4 + 21

5x = 25 (÷5)

x = 5

X=5

Explanation: 6x + 4 = 11x - 21
1). Subtract 4 from both sides and you will get 6x = 11x -25.
2). Subtract 11x from both sides and you should get -5x = -25.
3). Divide the -5 with -25 to get x alone and you should get X=5!

Check your work:
6(5) + 4 = 34 & 11(5) - 21 = 34

Step-by-step explanation:

The first division was ...

a/-2 = 8

Multiplying by -2, we have ...

a = (-2)(8) = -16

The second division was ...

8/b = -4

Multiplying by b/-4, we have ...

8/-4 = b = -2

Then the quotient of interest is ...

a/b = (-16)/(-2)

Answers

Answer:

x =5

Step-by-step explanation:

transfer -2 to the other side it turns to +2

|2x-1|=7 +2

2x-1 =9

transfer -1 to the other side it turns to +1

2x=10

Divide both sides by 2

2x /2 = 10/2

x= 5

ok so first u add 2 to both sides
|2x-1|=5
then youre doing 2 equations
2x-1= 5 2x-1=-5
2x=6. 2x=-4

3. What is the slope and y-intercept of the linear equation y = -7x + 5 ? (2 points)
slope = 1/7
y-intercept = (5,0)
slope = 7
y-intercept = (5,0)
slope = -1/7
y-intercept = (0,5)
slope = -7
y-intercept = (0,5)

Answers

Answer:

slope = - 7, y- intercept = (0, 5 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 7x + 5 ← is in slope- intercept form

with slope m = - 7 and y- intercept c = 5 ⇒ (0, 5 )
