Find the value of x, please helppp
Answer:
x = 3
Step-by-step explanation:
The two triangles at the left have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 6x−2.
Using the same logic, the two triangles on the right have the same angles and share a side, so they are congruent. Therefore, the vertical side is also 9x−11.
So:
6x − 2 = 9x − 11
9 = 3x
x = 3

A company decides to buy a new delivery truck for $26,500. The truck’s resale value decreases at a rate of 15% per year. Write a function model that will show the resale value of the truck x years after purchase?
Answer:
y=26500-3975x
Step-by-step explanation:
15% of 26500 is 3975. so you need to take that away for each year
How do you know whether an equation is an identity? How many solutions does an identity have? Explain.
Choose the correct answer below.
A.
An equation is an identity if it can be rewritten as an equation of the form "variable=number," such as x=5 or y=3. Such an equation has an infinite number of solutions because a variable can be any number.
B.
An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.
C.
An equation is an identity if it can be rewritten as an equation of the form "variable=number," such as x=5 or y=3. Such an equation has only one solution, and the solution is called the identity of the variable.
Answer:
the correct answer is B
Step-by-step explanation:
HAVE A GREAT DAY!
The correct answer is B.
An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable.
An equation is a mathematical statement which is true only for some set of values.
An identify is a mathematical statement which is true only for all the values.
Here, only option B "An equation is an identity if it can be rewritten as 0=0. Such an equation has an infinite number of solutions because it reduces to a true statement regardless of the value of the variable." satisfies the condition.
So, option B is correct.

Calculate the distance between the points J=(-3, 2) and K=(2, -2) in the coordinate plane.
Give an exact answer (not a decimal approximation).
Answer:
[tex]\sqrt{41}[/tex]
Step-by-step explanation:
Hello!
In order to answer this question, we need to use the distance formula.
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The order of these points can be chosen in any way, but they need to be done in the same pair (just like when you find the slope).
For this problem, let's let the J pair be the [tex]x_2, y_2[/tex] pair and the K pair be the [tex]x_1,y_1[/tex] pair.
[tex]x_2[/tex] = -3
[tex]x_1[/tex] = 2
[tex]y_2[/tex] = 2
[tex]y_1[/tex] = -2
Now, let's plug these points in.
[tex]\sqrt{(-3-2)^2+(2-(-2))^2}[/tex]
[tex]\sqrt{(-3-2)^2+(2+2)^2}[/tex]
[tex]\sqrt{(-5)^2+(4)^2}[/tex]
[tex]\sqrt{25+16}[/tex]
[tex]\sqrt{41}[/tex]
Thus, the distance between points (-3,2) and (2,-2) is [tex]\sqrt{41}[/tex].

After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y in terms of minutes x?
A. y=-8x+1.5
B. y=1.5x+8
C. y=8x+1.5
D. y=-1.5x+8
Given:
After 4 minutes of reading, Aaron was on page 14 of his book.
After 8 minutes he was on page 20.
To find:
The equation that models the page number, y in terms of minutes x.
Step-by-step explanation:
Let y be the page number after x minutes of reading.
After 4 minutes of reading, Aaron was on page 14 of his book. So, the line must be passes through (4,14).
After 8 minutes he was on page 20. So, the line must be passes through (8,20).
The equation of line which passes through two points is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The required line passes through (4,14) and (8,20), so the equation is
[tex]y-14=\dfrac{20-14}{8-4}(x-4)[/tex]
[tex]y-14=\dfrac{6}{4}(x-4)[/tex]
[tex]y-14=1.5(x-4)[/tex]
[tex]y-14=1.5x-6[/tex]
Add 14 on both sides.
[tex]y-14+14=1.5x-6+14[/tex]
[tex]y=1.5x+8[/tex]
Therefore, the correct option is B.

PLEASE HELP FAST!! Lake Alice is filled with alligators and turtles. The number of turtles is 16 less than 3 times the number of alligators in the lake. There are 200 reptiles total. Create an equation along with the correct answer to it. What does your answer mean in terms of the real-world scenario? (interpret it).
Answer:
72 alligators, 128 turtles
Step-by-step explanation:
When you put the words into the form of an equation, with a being alligators, you get
3a-16=200
So you have to do 'letters left numbers right'. This gives you
3a=216
Now you have to divide. 216 divided by 3 equals 72. So there are 72 alligators. 200 minus 72 equals 128, so there are 128 turtles
Answer:
the answer is there are 162 alligators and 38 turtles
Step-by-step explanation: See so 54X3= 162
and 54-16=38
then 162+38=200
Your jazz band is selling tickets for a school dance. Student tickets are $8.00 and adult tickets are $15.00. If you sold 167 tickets for a total revenue of $1630, how many of each ticket did you hand sell?
Write and solve a system of equations for each scenario.
Answer:
Step-by-step explanation:
8s + 15a = 1630
s + a = 167
8s + 15a = 1630
-8s - 8a = -1336
7a = 294
a = 42 adult tickets
s + 42 = 167
s = 125 student tickets

Solve in terms of d. r^2/d^2 = Gt
Answer:
sqrt(r^2/ Gt) =d
Step-by-step explanation:
r^2/d^2 = Gt
Multiply each side by d^2
r^2/d^2 * d^2 = Gt * d^2
r^2 = Gt d^2
Divide each side by Gt
r^2/ Gt = Gt d^2 / Gt
r^2/ Gt = d^2
Take the square root of each side
sqrt(r^2/ Gt) = sqrt( d^2 )
sqrt(r^2/ Gt) =d
