The Nature of Roots Of a Quadratic Equation help me with these pls
if you answer correctly i'll mark you as brainliest answer
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.

Colleen divided integer a by −2 and got 8. Then she divided 8 by integer b and got −4. Find the quotient of integer a and integer b.
/ = division
a/b =
9514 1404 393
Answer:
8
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)
a/b = 8

Ralph wants to build a rectangular deck with a predefined area of 66 feet squared. One side of the deck will be 5 feet longer than the other. To find the side lengths, he first writes the equation (x)(x+5)=66 and later simplifies (x-6)(x+11)=0 it to , where x is the length of the shorter side. Which of these are the side lengths, in feet, of the rectangular deck? Select all that apply
Answer:
The shorter side is 6 ft and the longer side is 11 ftStep-by-step explanation:
The options are not given, but we could solve and arrive at an answer
say the shorter side is x
and the longer side is x+5
we know that the area of a rectangle is given as
x*(x+5)=66
open the bracket
x^2+5x=66
x^2+5x-66=0
Find two factors of -66 whose sum equals the coefficient of the middle term, which is 5 .
the factors are 11 and -6
splitting the middle term using the two factors 11 and -6
x2 +11x - 6x - 66=0
x(x+11)-6(x+11)=0
(x-6)=0
x=6
(x+11)=0
x=-11
The shorter side is 6 ft and the longer side is 11 ft
solve: |2x - 1| - 2 = 7
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

a)natural
b)whole
c)integer
d)rational
e)irrational

Answer: (6) a (7) b (8) d (9) d
Step-by-step explanation:
a) Natural Numbers: 1, 2, 3, ...
b) Whole Numbers: 0, 1, 2, 3, ... (add zero to the Natural numbers)
c) Integers: ..., -3, -2, -1, 0, 1, 2, 3, ... (add negatives to the Whole numbers)
d) Rationals: Add terminating and repeating decimals to Integers.
************
e) Irrationals: Non-repeating decimals that are non-terminating. This is its own category so cannot be a Rational number or above.
f) Real Numbers: ALL of the above (a - e) are Real numbers.
6) The variable (d) represents the number of dogs. You cannot have a fraction of dog (rational), a negative number of dogs (integer), or zero dogs (whole) so the variable will be a NATURAL number.
7) The variable (b) represents the number of baths. You cannot have a fraction of a bath (rational), a negative number of baths (integer), but you can have zero baths so the variable will be a WHOLE number.
(8) The variable (n) represents the number of nails. You can have a fraction of a nail so the variable will be a RATIONAL number.
(9) The variable (h) represents the number of pounds of hair. You can have a fraction of a pound so the variable will be a RATIONAL number.
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)
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 )

Given proportions
Equations as per ratio and solution for each
c. ..................................
25 ÷ 2 1/2 = 100 ÷ x25 ÷ 5/2 = 100 ÷ xx = 100×5/2÷25x = 10100 yards in 10 seconds
d. ..................................
480 ÷ 4 = z ÷ 1120 = zz = 120120 heartbeats in 1 minute
Answer:
c. y = 10 secs.d. z = 120 heartbeatsStep-by-step explanation:
c. ratio and proportion:
25 yards = 100 yards
2.5 sec. y sec.
cross multiply:
100 (2.5) = 25 (y)
simplify:
y = 250 / 25
y = 10 secs.
------------------------------------------
d. ratio and proportion:
480 heartbeats = z heartbeats
4 mins. 1 min.
cross multiply:
4 (z) = 480 (1)
simplify:
z = 480 / 4
z = 120 heartbeats

Drew had $48 in his savings account. Each week he added $8 to his account. Stacie had $87 in her account. Each week she took $5 out. After how many weeks will they have the same amount of money in their savings accounts?
What would be the equation to figure this out?
Answer:
after 3 weeks
Step-by-step explanation:
y=8x
y=-5x
y=8*3=24+48=72
y=-5*3=-15
87-15 is 72
after 3 weeks
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".

Write an equation of the line with a slope of -3/4 and y-intercept of -6
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 + cwhere; m = slope and c = y-intercept
Therefore; the equation of the required line is;
y = (-3/4)x + (-6)4y = -3x - 244y + 3x = -24Read more;
