Question 3 (1 point)
When f= 2 and g= 3 by how much does the value of 4f2−g exceed the value of 3f2 −3g?
Answer:
1. q = p - mn
2. c = -6
3. 10
Step-by-step explanation:
1.
[tex]mn=p-q\\\textsf{add q to both sides}\implies mn + q = p\\\textsf{subtract mn from both sides}\implies q = p-mn[/tex]
2.
[tex]5c+23=c-1\\\textsf{subtract 23 from both sides}\implies5c=c-24\\\textsf{subtract c from both sides}\implies4c=-24\\\textsf{divide both sides by 4}\implies c=-6[/tex]

To see which option is the most accurate one, we will verify all the options to see which is correct.
________________________________________________Option A (Correct/Incorrect)
This is correct.Option A (Reasoning):
In this step, we can see that 3/4 was added to both sides. This can only mean that the property used here is the Addition property of Equality.
________________________________________________Option B (Correct/Incorrect)
This is incorrectOption B (Reasoning):
In this step, subtraction has not been used. It has been clearly stated that 3/4 was added to both sides.
________________________________________________Option C (Correct/Incorrect)
This is incorrectOption C (Reasoning):
In this step, multiplication has not been used. It has been clearly stated that 3/4 was added to both sides.
________________________________________________Option D (Correct/Incorrect)
This is incorrectOption D (Reasoning):
In this step, division has not been used. It has been clearly stated that 3/4 was added to both sides.
________________________________________________Option A is correct.
Addition property of equality is applied in the first step of equation x/4-3/4=16.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is x/4-3/4=16
x divided by four minus three divided by four equal to sixteen.
The first step to solve this equation as
x/4-3/4+3/4=16+3/4
Which means we have added 3/4 on both sides of the equation.
As per the addition property of equality, when we add the same number to both sides of an equation then the two sides remain equal.
So we have used the addition property of equality
Hence, addition property of equality is applied in the first step of equation x/4-3/4=16.

look at the simultaneous equations: x+y=a and 2x+y=b. write an expression for x in terms of a and b. write and expression for y in terms of a and b, giving your answer as simply as possible
An expression for x in terms of a and b is y = b - 2x and an expression for y in terms of a and b is y = 2a - b.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, A system of equations x + y = a and 2x + y = b.
Now,
x + y = a.
x = a - y and y = a - x.
2x + y = b.
2x = b - y.
x = (b - y)/2.
y = b - 2x.
An expression for x in terms of a and b is,
x + y = a
x + b - 2x = a.
- x = a - b.
x = b - a.
An expression for y in terms of a and b is,
2(a - y) + y = b.
2a - 2y + y = b.
2a - y = b.
- y = b - 2a.
y = 2a - b.

Problem 4: Solve the initial value problem
[tex]y' = (y + 1)(y - 2)[/tex]
[tex]y(0) = 1[/tex]
Separate the variables:
[tex]y' = \dfrac{dy}{dx} = (y+1)(y-2) \implies \dfrac1{(y+1)(y-2)} \, dy = dx[/tex]
Separate the left side into partial fractions. We want coefficients a and b such that
[tex]\dfrac1{(y+1)(y-2)} = \dfrac a{y+1} + \dfrac b{y-2}[/tex]
[tex]\implies \dfrac1{(y+1)(y-2)} = \dfrac{a(y-2)+b(y+1)}{(y+1)(y-2)}[/tex]
[tex]\implies 1 = a(y-2)+b(y+1)[/tex]
[tex]\implies 1 = (a+b)y - 2a+b[/tex]
[tex]\implies \begin{cases}a+b=0\\-2a+b=1\end{cases} \implies a = -\dfrac13 \text{ and } b = \dfrac13[/tex]
So we have
[tex]\dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = dx[/tex]
Integrating both sides yields
[tex]\displaystyle \int \dfrac13 \left(\dfrac1{y-2} - \dfrac1{y+1}\right) \, dy = \int dx[/tex]
[tex]\dfrac13 \left(\ln|y-2| - \ln|y+1|\right) = x + C[/tex]
[tex]\dfrac13 \ln\left|\dfrac{y-2}{y+1}\right| = x + C[/tex]
[tex]\ln\left|\dfrac{y-2}{y+1}\right| = 3x + C[/tex]
[tex]\dfrac{y-2}{y+1} = e^{3x + C}[/tex]
[tex]\dfrac{y-2}{y+1} = Ce^{3x}[/tex]
With the initial condition y(0) = 1, we find
[tex]\dfrac{1-2}{1+1} = Ce^{0} \implies C = -\dfrac12[/tex]
so that the particular solution is
[tex]\boxed{\dfrac{y-2}{y+1} = -\dfrac12 e^{3x}}[/tex]
It's not too hard to solve explicitly for y; notice that
[tex]\dfrac{y-2}{y+1} = \dfrac{(y+1)-3}{y+1} = 1-\dfrac3{y+1}[/tex]
Then
[tex]1 - \dfrac3{y+1} = -\dfrac12 e^{3x}[/tex]
[tex]\dfrac3{y+1} = 1 + \dfrac12 e^{3x}[/tex]
[tex]\dfrac{y+1}3 = \dfrac1{1+\frac12 e^{3x}} = \dfrac2{2+e^{3x}}[/tex]
[tex]y+1 = \dfrac6{2+e^{3x}}[/tex]
[tex]y = \dfrac6{2+e^{3x}} - 1[/tex]
[tex]\boxed{y = \dfrac{4-e^{3x}}{2+e^{3x}}}[/tex]

Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.
Step-by-step explanation:
Hope this helps =)
Answer:
w = 9
Step-by-step explanation:
Rearrange terms
4w + 18 = 6w
Subtract 18 from both sides of the equation
4w+18-18 = 6w -18
Simplify
4w=6w-18
Subtract 6w from both sides of the equation
4w-6w=6w-18-6w
Simplify
-2w=-18
Divide both sides of the equation by the same term
-2w = -18/-2
Simplify
w = 9
