Simplify the given algebraic expression.
9{9b-[2-3(9b-5)]}
Please I need an answer for this
Thanks!!!
After simplifying the algebraic expression 9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }, we get the result as 324 b - 153.
We are given the algebraic expression:
9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }
We need to simplify the expression.
For this, we will use the BODMAS rule.
B - Brackets
O - Of
D - Division
M - Multiplication
A - Addition
S - Subtraction
So, simplifying the expression, we get that:
9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }
= 9 { 9 b - [ 2 - 27 b + 15 ] }
= 9 { 9 b - 2 + 27 b - 15 }
= 9 { 9 b - 2 + 27 b - 15 }
= 81 b - 18 + 243 b - 135
= 324 b - 153
Therefore, after simplifying the algebraic expression 9 { 9 b - [ 2 - 3 ( 9 b - 5 ) ] }, we get the result as 324 b - 153.

How much work is done lifting a 10 pound object from the ground to the top of a 40 foot building if the cable used weighs 2.5 pounds per foot?
Answer:
2,400 foot-pounds
Step-by-step explanation:
Say at any instant x is length of Rope
Work done in lifting rope by dx amount will be:
dw = -(2.5x + 10)dx
w = -(40)∫(2.5x+10)dx
w = (2.5(40)^2) / 2 + 10(40)
w = 2000 + 400
w = 2,400 foot-pounds

Eugene and Jessica each improved their yards by planting hostas and geraniums. They bought
their supplies from the same store. Eugene spent $150 on 18 hostas and 6 geraniums. Jessica
spent $113 on 7 hostas and 16 geraniums. Find the cost of one hosta and the cost of one
geranium.
The cost of one hosta is approximately $7 and the cost of one geranium is approximately $4.
To find the cost of one hosta and one geranium, we can set up a system of equations based on the given information.
Let's assume the cost of one hosta is represented by 'h' and the cost of one geranium is represented by 'g'.
From the information given, we can set up the following equations:
Eugene's spending:
18h + 6g = $150
Jessica's spending:
7h + 16g = $113
We can now solve this system of equations to find the values of 'h' and 'g'.
Multiplying the first equation by 2 and the second equation by 3 to eliminate 'g', we get:
36h + 12g = $300
21h + 48g = $339
Now, we can subtract the second equation from the first to eliminate 'h':
(36h + 12g) - (21h + 48g) = $300 - $339
36h - 21h + 12g - 48g = -$39
15h - 36g = -$39
Simplifying further, we have:
15h - 36g = -$39
Now we can solve this equation for 'h' and substitute the value back into any of the original equations to find 'g'.
Let's solve for 'h':
15h = 36g - $39
h = (36g - $39) / 15
Substituting this value of 'h' into Eugene's equation:
18[(36g - $39) / 15] + 6g = $150
(648g - $702) / 15 + 6g = $150
648g - $702 + 90g = $150 * 15
738g - $702 = $2250
738g = $2250 + $702
738g = $2952
g = $2952 / 738
g ≈ $4
Now, substituting the value of 'g' back into Eugene's equation:
18h + 6($4) = $150
18h + $24 = $150
18h = $150 - $24
18h = $126
h = $126 / 18
h ≈ $7
Therefore, the cost of one hosta is approximately $7 and the cost of one geranium is approximately $4.

Given that f(x) = x2 - 5x+6, evaluate the function f(6).
Answer:
f(6) = 12
Step-by-step explanation:
We are given the following function:
\(f(x) = x^2 - 5x + 6\)
Evaluate the function f(6).
This is \(f(x)\) when \(x = 6\). So
\(f(6) = 6^2 - 5(6) + 6 = 36 - 30 + 6 = 12\)
f(6) = 12 is the answer.

find the constant of proportional (r) in the equation y = rx
Answer:
Constant of proportionality,
Step-by-step explanation:
Constant of proportionality states that the constant value of the ratio of two proportional quantities x and y,
it is written in the form of y = kx, where k is the constant of proportionality.
Given the equation: .....[1]
where r is the constant of proportionality.
From the table we consider
x = 14 and y = 1.4
Substitute these given values in [1] to solve for r;
Divide both sides by 14 we get;
therefore, the Constant of proportionality,
A straight highway is 100 miles long, and each mile is marked by a milepost numbered from 0 to 100. A rest area is going to be built along the highway exactly 7 miles away from milepost 58. If m is the milepost number of the rest area, which of the following equations represents the possible locations for the rest area?
Answer:
Step-by-step explanation:
The milepost number of the rest area is 7 miles away from milepost 58, so it can be represented by the equation:
m = 58 + 7
This equation states that the milepost number of the rest area is equal to 58 plus 7, or 65. Therefore, the rest area can be located at milepost 65.

How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.
The bills are replaced, hence we consider that for each trial, there is a 1/4 probability of selecting a $1 bill, as one out of the four bills are of $1.
Hence the probability that each bill is a $1 bill is obtained as follows:
p = 1/4 x 1/4

1. Solve the equation 4x + 6 = 1 + 3 graphically.
Notice that the equation given:
4 x + 6 = x + 3
has been represented on the plane by graphing the lines:
y = 4 x + 6, and y = x + 3
and looked for the point at which they intersect.
That point is marked in blue, and we can read its coordinates:
x = -1 and y = 2
so the value for x is -1.
Then we say that the equation 4 x + 6 = x + 3 has for solution x = -1.

The graph is missing, so i have attached it.
Answer:
From 0 hours to 2 hours.
Step-by-step explanation:
From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.
Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.
After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.
Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.

Why is it important to study parallelograms?
How does it apply in your life? in your own words not form an internet source
Answer:
Step-by-step explanation:
Just like any shape and/or geometry in general they are very important. Regardless of what you will ultimately study they can be used in many normal life scenarios. Since everything in our world is a shape you may need to calculate if something may fit somewhere, or if a certain fence can be made a certain way. This also applies to parallelograms, maybe you are trying to build a cabinet that will go in the corner, but the corner is not a 90 degree angle, knowing parallelograms and geometry can help you design and build the best cabinet.

ŷ = bX + a
Where
b = SP/SSX = 1055.63/1343.88 = 0.78551
a = MY - bMX = 31.13 - (0.79*35.38) = 3.33764
