Answer:
x=4
Step-by-step explanation:
Let's solve your equation step-by-step.
2x−3=x+1
Step 1: Subtract x from both sides.
2x−3−x=x+1−x
x−3=1
Step 2: Add 3 to both sides.
x−3+3=1+3
x=4
Answer:
x=4
2x - 1x = x
x-3= 1
3+1 =4
so x=4

What is the probability of obtaining a number bigger than 2 and a head?
Answer:
1/3 or 33.33333333%
Step-by-step explanation:
The chance of getting a head in the coin flip is 1/2 or 50%.
The chance of getting a number bigger than 2 (3,4,5,6) is 4/6 or 2/3 or 66.6666666666%. (There are a total of four possibilites in six.)
Hence, 50% * 2/3 = 33.333333333333%.

Please help me, This is the only question I don’t understand pleas help me I would really appreciate it thank you!
Answer:
C
Step-by-step explanation:
A proportional equation is in the form:
[tex]\displaystyle y=kx[/tex]
Where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.
An important aspect of a proportional equation is that it passes through the origin. That is, it has no y-intercept (or a constant value).
From our choices, the only choices that don’t have y-intercepts are C and D.
However, D is not a linear function.
Therefore, our answer is C.
And our constant of proportionality is 1/2.
If p is inversely proportional to the square of q, and p is 19 when q is 8, determine p when q is equal to 2
Answer:
p = 304
Step-by-step explanation:
Given p is inversely proportional to q² then the equation relating them is
p = [tex]\frac{k}{q^2}[/tex] ← k is the constant of proportion
To find k use the condition p = 19 when q is 8, then
19 = [tex]\frac{k}{8^2}[/tex] = [tex]\frac{k}{64}[/tex] ( multiply both sides by 64 )
k = 1216
p = [tex]\frac{1216}{q^2}[/tex] ← equation of proportion
When q = 2, then
p = [tex]\frac{1216}{2^2}[/tex] = [tex]\frac{1216}{4}[/tex] = 304
The value of p is equal to 304 when q is equal to 2
Given :
If p is inversely proportional to the square of q
when y is inversely proportional to x then [tex]y=\frac{k}{x}[/tex]
given that p is inversely proportional to the square of q. the equation becomes
[tex]p=\frac{k}{q^2}[/tex]
when p is 19 the value of q is 8
Replace the values and find out k
[tex]p=\frac{k}{q^2}\\19=\frac{k}{8^2}\\19=\frac{k}{64}\\[/tex]
Multiply both sides by 64
k=1216
Now we find out p when q is 2
Replace k value and q value to find out p
[tex]p=\frac{k}{q^2} \\\\p=\frac{1216}{2^2} \\p=304[/tex]
The value of p is equal to 304 when q is equal to 2

3c+5=23 what is c? c=3 c=6 c=7 c=18
Answer:
c = 6
Step-by-step explanation:
Subtract 5 from both sides. This is to cancel out the + 5. You have 3c = 18Divide both sides by 3. 18/3 = 6, so c = 6.Answer:
First, rearrange the equation so you can get the like terms together
3c=23-5
3c=18
c=18/3
c=6

(0, 2) is the y intercept of the given graph, option B is correct.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The line is passing through the points (3, 0) and (0,2)
We have to find the slope
m=2/-3
=-2/3
Now let us find y intercept
0= -2/3(3) +b
b=2
Hence, (0, 2) is the y intercept of the given graph, option B is correct.

Identify the determinants for the given linear system: 5x + 2y = 14 −3x − 5y = 3
Answer:
Step-by-step explanation:
|A|= 5, 2, -3, -5
|Ax|= 14, 2, 3, -5,
|Ay|= 5, 14, -3, 3
The determinants are, [tex]D = \begin{vmatrix}5 & 2 \\- 3 & - 5\end{vmatrix}[/tex], [tex]D_x = \begin{vmatrix}14 & 2 \\3 & - 5\end{vmatrix}[/tex] and [tex]D_y = \begin{vmatrix}14 & 5\\3 & - 3\end{vmatrix}[/tex].
What are the three types of solutions for a system of linear equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
The given linear system is, 5x + 2y = 14 and - 3x - 5y = 3.
In terms of determinants, it can be written as,
[tex]D = \begin{vmatrix}5 & 2 \\- 3 & - 5\end{vmatrix}[/tex].
[tex]D_x = \begin{vmatrix}14 & 2 \\3 & - 5\end{vmatrix}[/tex].
[tex]D_y = \begin{vmatrix}14 & 5\\3 & - 3\end{vmatrix}[/tex].
[tex]x = \frac{D_x}{D}[/tex] and [tex]y = \frac{D_y}{D}[/tex].

simplify this expression: 3c + 7 - 9c
Answer:
-6c + 7
Step-by-step explanation:
To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.
3c + (-9c) = -6c
The 7 stays the same, so the simplified expression is -6c + 7.
