What is linear equation with example?
Ax+By=C represents a two-variable linear equation in its standard form. A standard form linear equation is, for instance, 2x+3y=5. Finding both intercepts of an equation in this format is rather simple (x and y).A linear equation with one variable has the conventional form Ax + B = 0. x is a variable, A is a coefficient, and B is constant in this situation.2t + 3/3 = 3t - 8/2
2( 2t + 3 ) = 3( 3t - 8 )
4t + 6 = 9t - 24
9t - 4t = 9 + 24
5t = 33
t = 33/5
t = 6.6

Robert has two more than three times the number of cards that Amanda has which expression represents the number of cards that Robert has
To state the equation that represents the given situation, we take x as the number of cards Amanda has. Three times the number of cards is 3x, two more is +2. It means that the expression that represents this situation is:
[tex]3x+2[/tex]f(x) = (x-1.5)^2 find the vertex
The given function is
[tex]f(x)=(x-1.5)^2[/tex]It is important to know that the function is in vertex form
[tex]f(x)=a(x-h)^2+k[/tex]Where h and k are the coordinates of the vertex.
Having said that, we can deduct that the vertex of the given function is (1.5, 0) because those are the values for h and k.
Hence, the answer is V(1.5, 0).Jay had 60 tickets he could turn in at the end of the year for extra-credit points he had earned during the year. Some tickets were worth two points and others were worth five points. If he was entitled to a total of 231 extra-credit points, how many two-point tickets did he have?
Answer:
23 2-points + 37 5-points = 231
Step-by-step explanation:
Answer:
53 two-point tickets.
Step-by-step explanation:
This is a system of equations:
x + y = 60
2x + 5y = 231
Then..
-2x - 2y = -120
2x + 5y = 231

4. During a long weekend, Devon paid a total of x dollars for a rental car so he could visit his family. He rented the care for 4 days at a rate of $36 per day. There was an additional charge of $0.20 per mile after the first 200 miles.
a. Write an expression to represent the amount Devon paid for additional mileage.
b. Write an expression to represent the number of miles over 200 miles that Devon drove.
c. How many miles overall did Devon drive overall if he paid $174 for the car rental? Show work.
Answer:
A)
c = 0.20m + 144
Where c is total cost and m is miles driven.
B)
c = (200 + 0.20m) + 144
C)
174 = 0.20m + 36x4
174 = 0.20m + 144
30 = 0.20m
30/0.20 = m
m = 150+200
m = 350miles

exercise after work, Albert (A) went running and Tanisha (T) walked for exercise. Their times and distances are showing in the graph below. How much as Albert running than Tanisha walking in miles per hour? Explain how you found your answer.
In the picture, there are two lines that graph distance versus time, so the slope of the line is teh rate or the speed of Albert or Tanisha.
We need to calculate the slope of each line. We can note that the two lines start in the origin point (0, 0), so:
[tex]\begin{gathered} \text{For Albert, we can s}ee\text{ that the point (10, 1) is in the line, so:} \\ slopeofAlbert=m_A=\frac{1}{10}=0.1\frac{miles}{\min ute} \\ \text{For Tanisha, we can se}e\text{ thet the point (}20,\text{ 1) is in the line. so:} \\ slopeofTanisha=m_T=\frac{1}{20}=0.05\frac{miles}{\min ute} \end{gathered}[/tex]The different between the slopes (speed) is:
[tex]\begin{gathered} m_A-m_T=0.1\frac{miles}{\min ute}-0.05\frac{miles}{\min ute}=0.05\frac{miles}{\min ute} \\ In\text{ miles/hours is:} \\ m_A-m_T=0.05\frac{miles}{\min ute}\cdot\frac{60\text{minutes}}{1\text{hour}}=3\frac{miles}{hour} \end{gathered}[/tex]Albert goes 3 miles/hour faster than Tanisha
Let d represent the number of $2 decreases i price. Let r be the company’s revenue. Write a quadratic function that reflects the company’s revenue.
Answer:
Let d be the number of $2 decreases, and r be the company´s revenue, then the company can sell:
[tex]800+40d[/tex]cellphones per week at a price of:
[tex]80-2d[/tex]dollars.
Therefore, the quadratic equation that represents the revenue is:
[tex](800+40d)(80-2d)\text{.}[/tex]Now, graphing the above equation we get:
From the above graph, we can determine the vertex and the vertex gives us for which value of d the company gets the maximum revenue.
The company should charge $80-10($2)=$80-$20=$60.
One positive integer is 2 less than twice another. The sum of their squares is 745.
The numbers are 13 and 24
What is Integers?
The negative numbers are the additive inverses of the corresponding positive numbers.[2] In the language of mathematics, the set of integers is frequently denoted by the boldface Z or blackboard bold displaystyle mathbb Z mathbb Z.[3][4][5] An integer is the number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer with a minus sign
y=first number
x=2y-2 (second number)
y^2+(2y-2)^2=745
y^2+4y^2-8y+4=745
5y^2-8y+4-745=0
5y^2-8y-741=0
Now, from the equation we can solve
5y^2 -65y +57y - 741 = 0
5y(y - 13) + 57(y - 13) = 0
(5y + 57)(y - 13)= 0
now, since the Integers are positive so the value obtained from (5y + 57) = 0 can't hold true.
So, y-13 = 0
y = 13
The first number is : 13
The second number is :
x = 2(13) - 2
x = 26 - 2
x = 24
The second number is : 24
Hence, the numbers are 13 and 24

Create your own quadratic equation whilst explaining how to use the quadratic formula to solve it. Be specific, using a, b, and c of your equation and give solutions to theequation you chose.
Let the quadratic equation is
[tex]x^2-8x+16=0[/tex]Here, a is the coefficient of x^2, b is the coefficient of x and c is the constant.
For the equation we have a = 1, b = -8 and c = 16.
We know that the quadratic formula is given by:
[tex]x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}[/tex]So, the solution of the quadratic equation is:
[tex]\begin{gathered} x=\frac{-(-8)\pm\sqrt[]{(-8)^2-4(1)(16)}}{2(1)} \\ x=\frac{8\pm\sqrt[]{64-64}}{2} \\ x=\frac{8\pm\sqrt[]{0}}{2} \\ x=\frac{8}{2} \\ x=4 \end{gathered}[/tex]Thus, there are two real and equal solutions for the given quadratic equation that is x = 4 and x = 4.

Given:
The triangles EFG and PQR are given.
To find: The correct answer
Explanation:
a) An angle bisector:
As we know,
An angle bisector is a line or ray that divides an angle into two congruent angles.
Here, The line FJ is the angle bisector for angle F.
Thus, the angle bisector is line FJ.
b) Perpendicular bisector:
As we know,
A perpendicular bisector is a line that bisects another line segment at a right angle, through the intersection point.
Here, the line SL bisects another line segment PQ at a right angle, through the intersection point S.
Thus, the perpendicular bisector is SL.
c) A point is equidistant from the line segment FE and EG:
The point that is equidistant to all sides of a triangle is called the incenter.
Here, H is the point that is equidistant from the line segment FE and EG.
Thus, the point is H only.
d) A point is equidistant from the points P and Q:
The point that is equidistant to all vertices of a triangle is called the circumcenter.
Here, L is the point that is equidistant from the points P and Q.
Thus, the point is L only.

5.95
11.682
16.8
Answer:
11.682 many times larger
Answer:
16.8
Step-by-step explanation:
To find how many times larger (1.008 × 10¹) is than (6 × 10⁻¹), divide the first expression by the second expression:
[tex]\implies \dfrac{1.008 \times 10^1}{6 \times 10^{-1}}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{ab}{cd}=\dfrac{a}{c} \times \dfrac{b}{d}:[/tex]
[tex]\implies \dfrac{1.008}{6} \times \dfrac{10^1}{10^{-1}}[/tex]
Divide the numbers 1.008 and 6:
[tex]\implies 0.168 \times \dfrac{10^1}{10^{-1}}[/tex]
[tex]\textsf{Apply the exponent rule} \quad \dfrac{a^b}{a^c}=a^{b-c}:[/tex]
[tex]\implies 0.168 \times 10^{(1-(-1)}[/tex]
Simplify:
[tex]\implies 0.168 \times 10^{2}[/tex]
[tex]\implies 0.168 \times 10 \times 10[/tex]
[tex]\implies 1.68 \times 10[/tex]

The length of a rectangular piece of steel in a bridge is 2 meters less than triple the width. The perimeter of the piece of steel is 60 meters. Find the length of the pieceof steel. Find the width of the piece of steel.
Let "x" represent the width of the rectangular steel, then the length, which is 2meters less than triple the width, can be expressed as "3x-2".
The perimeter of the rectangular piece is 60meters.
The formula for the perimeter is the following:
[tex]P=2w+2l[/tex]Replace the formula with the expressions for the width and length and the given perimeter of the piece of steel:
w=x
l=3x-2
P=60
[tex]60=2x+2(3x-2)[/tex]From this expression, you can determine the value of x.
-First, distribute the multiplication on the parentheses term
[tex]\begin{gathered} 60=2x+2\cdot3x-2\cdot2 \\ 60=2x+6x-4 \end{gathered}[/tex]-Second, simplify the like terms and pass "-4" to the left side of the expression by applying the opposite operation "+4" to both sides of it
[tex]\begin{gathered} 60=8x-4 \\ 60+4=8x-4+4 \\ 64=8x \end{gathered}[/tex]-Third, divide both sides by 8 to determine the value of x
[tex]\begin{gathered} \frac{64}{8}=\frac{8x}{8} \\ 8=x \end{gathered}[/tex]The value of x is 8m, which means that the width of the piece of steel is 8m
To determine the length you just have to replace the expression by x=8
[tex]\begin{gathered} l=3x-2 \\ l=3\cdot8-2 \\ l=24-2 \\ l=22 \end{gathered}[/tex]The length is 22m
