Solve for x: -2x - 5 = 4
Answer:
x=−20
Step-by-step explanation:
Step by Step Solution:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
-4 -4 • 5
-4 = —— = ——————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (-4 • 5) x + 20
———————————— = ——————
5 5
Equation at the end of step
2
:
x + 20
—————— = 0

When a fraction equals zero
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x+20
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x+20 = 0
Solving a Single Variable Equation:
3.2 Solve : x+20 = 0
Subtract 20 from both sides of the equation :
x = -20
One solution was found :
x = -20
Answer:
x=-4.5 or -9/2
Step-by-step explanation:
The first step is to isolate x to do this you add 5 to both sides which then gives you -2x=9 the next step is to divide by negative 2 which would give you -9/2 which simplifies to -4.5.
A child learns new words very quickly, but their vocabulary grows slower as they grow up. There is no upper-limit to the size of a person's vocabulary, so a logarithmic growth model is reasonable. The number of words can be related to the child's age (in months) according to the following formula: W(m)=10,000 ⋅ log(m) − 13,000
where m is the number of months in a person's age.
How many vocabulary words would a person have after 20 years (240 months) ?
A. 10.3
B. 10,802
C. 21.1
D. 13,000

Step-by-step explanation:
If the price of a yo-yo in a shop increased by 20% and is now $18.00, what was the original price?
So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.
Hope it helped :)
The original price was $15.00
The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:
18 = x × (1 + 20%)
18 = x × 1.20
18 = 1.20x
x = 18 / 1.20
x = $15.00
In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

Look at the function f(x) = −x + 5. Which of the following describes the domain and range of the function and its inverse?
Answer:
the first
0 5
5 0
Step-by-step explanation:
the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"
because this is just a matter of definition. the function itself would not suggest any limits.
and in that regard the function definition is basically irrelevant.
the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.
so, the second set of definitions is not possible, if we are really trying to define the inverse function.

Answer:
r = 1.7389 in
Step-by-step explanation:
(A) Volume of hollow block = 540 in^3
(B) volume of block without Hollows = b×d×h
= 6 ×16 ×8
= 768 in^3
(C) volume of 3 hollows = 3 ×( pi ×r^2 h)
= 3 ×( pi ×r^2 ×8)
= 24 ×pi ×r^2
solve,
A = B - C
540 = 768- (24 ×pi ×r^2)
r^2 = (768- 540) / 24 pi
r = root(3.023943919)
r = 1.7389 in
An angle measures 132.6 more than the measure of a supplementary angle. What is the measure of each angle?
Answer:
Step-by-step explanation:
If the angle measures x, then the supplement measures 180-x.
This means x-132.6=180-x, and thus x=156.3
This means the angles measure 156.3 and 23.7 degrees.

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
We have to given that;
Point P partitions directed line segment AB in the ratio of 3 to 4.
And, A (-9, -9) and B (5,-2).
Now, The coordinate of Point P is find as;
⇒ P (x, y) = (3×5 + 4×- 9/ (3+ 4) , 3×-2 + 4×- 9 / (3 + 4) )
