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

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

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.

Step-by-step explanation:
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;

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 )
