a-15=4a-3
if u dont want spam then dont answer
Step-by-step explanation:
Simplify the equation to find the value of a.
Subtract 4a from both sides:
[tex] - 3a - 15 = - 3[/tex]
Add 15 to both sides:
[tex] - 3a = 12[/tex]
Divide each side by -3:
[tex]a = - 4[/tex]

Essay Definition of Citizenship:
In the literal sense a person who lives in a city is said to be a citizen. But in political science we use this terminal different sense. To find the real meaning of the term we are to go back to ancient Greece. Aristotle, the father of political science, called a person a citizen who would take a direct and active part in the administration of the state.
Since the states in ancient Greece were as small as the cities of Greece it was possible for the residents of the city-state to make law, to adjudicate and even enforce the law. These citizens did not include the slaves, women and manual workers. In such a case the number of the citizens was just half of the entire population. The position was not very different in the medieval Europe. There were serfs in the place of the slaves.
The position is quite different in modern nation-states, where all adult people are citizens who need not take an active part in the administration of the country, because it is not possible for the entire population of a vast country to meet together and make law and interpret it or enforce it.

danielle did not complete 15 of her 200 assignments last year. Kim said that is 0.075 of her assignments and Kelly said it is 0.75 of her assignments. Who is correct and how do you know?
Answer:
Kim
is correct
Step-by-step explanation:
Here, we want to know who is correct between Kim and Danielle
From the question, what is not completed is 15 out of 200
To find what is not completed, we divide 15 by 200
Thus, we have;
15/200 = 0.075
This mean Kim is correct

A customer pay 72$ for 18 sandwiches. If each sandwich cost the same amount , what is the cost per sandwich, in dollars?
Answer:
Each sandwich costs 4$.
Step-by-step explanation:
To find the answer we will divide 72$ by 18 and we get 4$.
The number of sandwiches and the total price of sandwiches are directly proportional.
Cost of 18 sandwiches = $72
Cost of 1 sandwich = $72/18
= $4
Hence the cost of 1 sandwich is $4.

The total cost for a month at a fitness club is made up of a fixed fee and a cost per visit. Information about the total cost, C, in dollars, for n visits is shown below Determine a possible fixed fee, cost per visit and equation for the new total cost.
Answer:
C = n + 25
Step-by-step explanation:
The total amount of money is C, so the equation has to equal C. n is the cost per visit and then you add the fixed fee in which I chose 25

express y= x² + 2x + 3 in the form of y= (x-h)² + k
Given:
The equation is
[tex]y=x^2+2x+3[/tex]
To find:
The vertex form of the given equation, i.e., [tex]y=x^2+2x+3[/tex].
Solution:
We have,
[tex]y=x^2+2x+3[/tex]
It can be written as
[tex]y=(x^2+2x)+3[/tex]
Add and subtract square of half of coefficient of x, i.e., [tex]\left(\dfrac{2}{2}\right)^2=1[/tex].
[tex]y=(x^2+2x+1)-1+3[/tex]
[tex]y=(x^2+2(x)(1)+1^2)+2[/tex]
[tex]y=(x+1)^2+2[/tex] [tex][\because (a+b)^2=a^2+2ab+b^2][/tex]
Therefore, the required form of given function is [tex]y=(x+1)^2+2[/tex].
in AABC, the measure of angle A=x degree, the measure of angle B=(2x)degrees, and the measure of angle C=(6x+18)degrees. What is the measure of angle B?
Answer:
m<B: 36
Step-by-step explanation:
x + 2x + 6x + 18 = 180
9x + 18 = 180
9x = 162
x = 18
m<B:
2x
2(18)
36
Answer:
m<B=36°
Step-by-step explanation:
The sum of angles in a triangle add up to 180°.
That means the sum of m<A+m<B+m<C=180°
We're given that:
m<A=x°
m<B=(2x)°
m<C=(6x+18)°
we can substitute those values as m<A, m<B, and m<C
x+2x+6x+18=180
combine like terms
9x+18=180
subtract 18 from both sides
9x=162
divide by 9
x=18°
we found the value of x, but we're not done yet
The question asks to find m<B, which is 2x°
in that case, we can substitute our known value to find the measure of <B
m<B=2x°
m<B=2(18)°
m<B=36°

y=-x+3
y=x^2+1
Answer:
[tex] - x + 3 = {x}^{2} + 1[/tex]
[tex] {x}^{2} + x = 2[/tex]
Answer:
Step-by-step explanation:
1st y=-x+3
Let's solve for x.
y=−x+3
Step 1: Flip the equation.
−x+3=y
Step 2: Add -3 to both sides.
−x+3+−3=y+−3
−x=y−3
Step 3: Divide both sides by -1.
−x/−1= y−3/−1
Answer:
x=−y+3
2nd queastion: y=x^2+1

Question should guns be allowed to be at school for example can a security guard have a gun?
Answer: First secutitys at my school dont even have nothing but a walkie talkies in there hands but I will say this we have cops walking around inside of our school and there all armed up because obvisouly their cops so i would think not security should not have a fire arm because what happens if a old lady a securrityguard she cant move fast so I think not they would have to deal it with by hand and there walkie talkies.
Step-by-step explanation:
Answer:no because they might be part of a crime and shoot up the school like boom bang bin bot pow and 500 people drop dead like me in the bed room.

Answer:
288 cm^3
Step-by-step explanation:
Hello
Can you help me to do these two exercises please I block on those please it is on the derivatives of a number
Thank you so much in advance!!!
Answer:
First rememeber that if we have a function like:
g(x) = x^n
then:
dg(x)/dx = g'(x) = n*x^(n - 1)
And also if we have:
g(x) = f(x) + h(x)
then:
dg(x)/dx = g'(x) = f'(x) + h'(x)
1) We have the function f(x) = (x + 1)^2
We can rewrite this as:
f(x) = x^2 + 2*x + 1
Using both things written above, we know that:
f'(x) = 2*x + 1*2 = 2*x + 2
And we want to find f'(-2), so we only need to evaluate the above function in x = -2, this is:
f'(-2) = 2*-2 + 2 = -4 + 2 = -2
f'(-2) = -2
b) I suppose that this refers to the inverse function of f(x)
An inverse function is such that:
g( f(x)) = x
f( g(x)) = x
For f(x) = (x + 1)^2
The inverse will be something that first cancels that square, and then subtracts 1.
Then:
g(x) = √x - 1
if we evaluate this in f(x) we get:
g( f(x)) = √(f(x)) - 1 = √(x + 1)^2 - 1 = (x + 1) - 1 = x
Then the inverse function of f(x) is:
g(x) = √x - 1
This can also be written as:
g(x) = x^(1/2) - 1
Then the derivative of this will be:
g'(x) = (1/2)*x^(1/2 - 1) = (1/2)*x^(-1/2) = (1/2)*(1/√x)
A middle school has 200 boys and 300 girls enrolled in the seventh-grade. The principal randomly selects 45 seventh-grade students to take a lunch survey. How many of the seventh-grade students selected for the survey should the principal expect to be boys?
Answer:18
Step-by-step explanation:
Given
The school has 200 boys and 300 girls
The ratio of boys and girls is 2:3
If 45 seventh grade students are selected then the ratio of boys and girls remain the same
suppose there are 2x boys and 3x girls, such that ratio is 2:3
[tex]\Rightarrow 2x+3x=45\\\Rightarrow 5x=45\\\Rightarrow x=9[/tex]
No of the boys are [tex]2x=2\times 9=18[/tex]

18
