4 times the sum of a number and 5 is 1 less than the same number
x = a number
4(x + 5) = x - 1
Now, let's distribute the 4
4x + 20 = x - 1
Subtract x and 20 from both sides.
3x = -21
Divide both sides by 3
x = -7

AR:AB = 1/5 means that AR has length equal to 1/5 of the length of AB.
To find the x coordinate of R, you take 4/5 of the x coordinate of A plus 1/5 of the x coordinate of B:
4/5 * 1 + 1/5 * 4 = 8/5
You do the same for the y coordinate:
4/5 * (-1) + 1/5 * 4 = 0
So the point R has coordinates (8/5, 0).
Morris borrowed $6 from his mother. so far, he has repaid $4. if debt is represented as a negative number, what number sentence shows the amount of jack's remaining dept.?
if it was negitive I would be -2
Step-by-step explanation:
so 6-4=2 and if you make that negative it would be -2
Answer:
-$6 + $4 = -$2
Step-by-step explanation:
Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.
Graph the given function. State the domain and range. y=-11√6-9x+1
4x+9=56 what is the value of x
4x + 9 = 56
To Find:The value of x.
Solution:4x + 9 = 56
The value of 9 changes when we take 9 to the Right Hand Side, we get
4x = 56 - 9
Now, The value of 4 changes when we take 4 to the Right Hand Side, we get
x = 47/4
Answer:The value of x is 47/4

Step-by-step explanation:
Let's investigate what happens when negative values appear under the radical symbol (as the radicand) for cube roots and square roots.
In some situations, negative numbers under a radical symbol are OK. For example, radnegnew14is not a problem since (-2) • (-2) • (-2) = -8, making the answer -2. In cube root problems, it is possible to multiply a negative value times itself three times and get a negative answer.
Difficulties, however, develop when we look at a problem such as radnegnew214. This square root problem is asking for a number multiplied times itself that will give a product (answer) of -16. There simply is no way to multiply a number times itself and get a negative result. Consider: (4) • (4) = 16 and (-4) • (-4) = 16.
CUBE ROOTS:
radnn1
BUT
SQUARE ROOTS:
n2
Yes, (-2) x (-2) x (-2) = -8.
No problem.
Nope! (4) x (4) ≠ -16.
Nope! (-4) x (-4) ≠ -16.
bullet Square roots are the culprits! The difficulties arise when you encounter a negative value under a square root. It is not possible to square a value (multiply it times itself) and arrive at a negative value. So, what do we do?
statement
The square root of a negative number does not exist among the set of Real Numbers.
When problems with negatives under a square root first appeared, mathematicians thought that a solution did not exist. They saw equations such as x2 + 1 = 0, and wondered what the solution n3 really meant.
In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545.
def The imaginary number "i" is the square root of negative one.
neg i
An imaginary number possesses the unique property that when squared, the result is negative.
irad1
Consider: irad2a
The process of simplifying a radical containing a negative factor is the same as normal radical simplification. The only difference is that the irad4 will be replaced with an "i ".
As research with imaginary numbers continued, it was discovered that they actually filled a gap in mathematics and served a useful purpose. Imaginary numbers are essential to the study of sciences such as electricity, quantum mechanics, vibration analysis, and cartography.
When the imaginary i was combined with the set of Real Numbers, the all encompassing set of Complex Numbers was formed.
A tortilla measures 8 inches in diameter, shown below. What is the tortilla's area?
The required area of tortilla is 16π square inches.
What is an area of a circle?
Area of a circle is defined as the region occupied by the circle in two-dimensional plane.
Mathematically,
A = π (d/2)²
where d is the diameter of circle
or, A = π r²
where r is the radius of circle.
Now, given diameter of tortilla is 8inches.
⇒ d = 8inches
Since,tortilla is a circle
So, area of tortilla A = π (d/2)²
⇒ A = π (8/2)²
⇒ A = π (4)²
⇒ A = 16π square inches
Hence, required tortilla's area is 16π square inches.
