3x +5 = 2x +15
Subtract 5 from both sides:
3x = 2x + 10
Subtract 2x from both sides:
X = 10
Answer:
The answer is x=10.
3x-2x=15-5.
x=10.

if you apply the changes below to the quadratic parent function, f(x)=x2, what is the equation of the new function shift 3 units left vertically stretch by a factor of 4 reflect over the a axis
Answer: B. g(x) = –4(x – 3)2
Step-by-step explanation: To apply the changes to the equation of a vertical stretch of 4 and a translation of 3 units to the right, as well as the correct answer would be choice B.
The reason for this is when you apply a vertical stretch, because it changes the y-values (which causes it to vertically stretch or appear skinnier when graphed), you would multiply 4 to f(x) which would look like 4x^2.
Then, since you have a reflection over the x-axis, you must multiply a -1 to f(x) to reflect it over the x-axis which would result in -4x^2.
Finally, it also asks to shift the graph right 3 which by moving it right, you change the x values meaning you will perform f(x-3) to achieve this (subtract the value from x when you move right, and add the value to x when you move left).

Answer:
B.
Step-by-step explanation:
From the number line, we can see that the blue line points to all values to the left of 5. This means all values less than 5.
Also, note that since the blue dot is closed, the inequality includes 5.
Therefore, the inequality that represents the graph is all values less than or equal to 5.
In notation, this is:
[tex]x\leq 5[/tex]
The answer is B
Answer:
your answer is B. [tex]x\leq 5[/tex]
Step-by-step explanation:
[tex]x\leq 5[/tex] means that your arrow should be point left which means less than the line under the less than means that the don´t should be shaded in
3. The minimum payment on a credit card is based on the total amount owed. A credit card company uses the following rules: For a bill less than $20 the entire amount is due, for a bill of at least $20 but less than $500, the minimum due is $20. For a bill of at least $500 but less than $1000 the minimum due is $40 and for a bill of at least $1000 but less than $1500 the minimum due is $80 dollars. For a bill of $1500 or more the minimum due is 1/10th of the bill.
a. Write a function to describe the minimum payment due.
b. What is the minimum payment due if the bill is $345?

Answer: B
Step-by-step explanation:
When you are multiplying exponents, if the base is the same, then you can directly add the exponents together.
We can see that both bases are 6. That means we can add the exponents.

The price for 2 student tickets and 4 adult tickets to a play is $50. Adult tickets are $5 more than student tickets. write an the equation
Answer:
2x + 4y = $50
x = $5, and y = $10
Step-by-step explanation:
let the price of student's ticket be represented by $x, and that of adult by $y. So that:
2x + 4y = $50 ................ 1
But, given that adult tickets are $5 more that student tickets.
i.e y = x + $5 ................. 2
Substitute equation 2 into 1, to have;
2x + 4(x + $5) = $50
2x + 4x + $20 = $50
6x = $30
x = $5
From equation 2,
y = 5 + 5
= $10
Therefore, the price of student tickets is $5 and adult tickets is $10.

How would you round 95687 to the nearest thousand?
Answer:
96,000
Step-by-step explanation:
To round to the nearest thousand, we need to look at the digit in the hundreds place, which is 6. Since 6 > 5, we know that we need to round up (because 6 is closer to 10 than it is to 0). Currently, the number is 95 thousand so when rounding up, the answer will be 96,000.
The ratio of fiction to nonfiction books in a classroom library is 2 to 3 . If there are 24 books nonfiction books in the classroom library , how many fiction books are there?
Answer:
16Step-by-step explanation:
Given the ratio of fiction to nonfiction books in a classroom library is 2 to 3, then the total ratio of both books will be 2+3 = 5. If there are 24 books non fiction books in the library, to get the amount of fictionbooks that are there we will follow the following steps.
First we will calculate the total number of books in the shelf;
3/5 * Total number of books = total non fiction books
3/5 * Total number of books = 24
3*Total number of books = 5*24
3*Total number of books = 120
Total number of books = 120/3
Total number of books = 40
Therefore there are 40 total of books on the shelf.
Total number of fiction books = 2/5 * 40
Total number of fiction books = 2* 8
Total number of fiction books = 16 books
Hence there are 16 fiction books on the shelf.
Evaluate the expression, given functions f and g: f(x) = 3x – 2, g(x) = 7 – x2.
3f(1) - 49(-2)
f(x) = 3x – 2, g(x) = 7 – x2.
3f(1) - 49(-2)
Substitute the given value into the function and evaluate.
101
The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the function,
f(x) = 3x – 2
Now,
f(1) = 3(1) - 2 = 1
So,
3f(1) - 49(-2) = 3×1 - 49(-2)
⇒ 3 + 98 = 101
Hence "The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101".

What is the solution Set to 2a+6=2a+5+1
Answer:
Infinite Amount of Solutions
Step-by-step explanation:
Step 1: Write out equation
2a + 6 = 2a + 5 + 1
Step 2: Combine like terms
2a + 6 = 2a + 6
Here we see that we have the same slope and same y-intercept or the same equation. When this happens, our solution set is infinite amount of solutions, as any value a can be plugged in and would be true.

Suppose you toss 6 coins. What is the probability that 3 of the coins are heads and 3 of the coins are tails
Answer:
12, either it will happen or it won't. It is true that each sequence of heads and tails is equally likely to occur – with probability 164, in this case. However, the number of those sequences having exactly three heads is not 32, but (63)=20, which leads to the correct answer of 516.
Step-by-step explanation:
Answer: 50%
Step-by-step explanation: Because the likelyhood would be as likely as not then that would be half of 100, or 50%

Find the average value of the function over the given interval. (Round your answer to three decimal places.) f(x)
Complete Question
Find the average value of the function over the given interval. (Round your answer to three decimal places.) f(x) = 12e^x, [−6, 6] Find all values of x in the interval for which the function equals its average value. (Enter your answers as a comma-separated list. Round your answers to three decimal places.)
Answer:
The average is
[tex]AV = 403[/tex]
The value of x is
[tex]x = 4[/tex]
Step-by-step explanation:
From the question we are told that
The equation is [tex]f(t) = 12e^x[/tex]
The points consider is [-6 , 6]
Generally the average value of the function over the given interval is mathematically represented as
[tex]AV = \frac{1}{z-w} \int\limits^ z_w {f(x)} \, dx[/tex]
[tex]AV = \frac{1}{ 6 - (-6)} \int\limits^{6}_{-6} { 12e^x} \, dx[/tex]
[tex]AV = \frac{1}{12 } e^x| \left 6} \atop {-6}} \right.[/tex]
[tex]AV = e^6 -e^{-6}[/tex]
[tex]AV = 403[/tex]
Generally when the function equal the average we have that
[tex]f(x) = 12e^{x} = 403[/tex]
[tex]e^{x} = 34[/tex]
[tex]x = ln(34)[/tex]
[tex]x = 4[/tex]
Find the equation of a Horizontal line containing the point (-1,3)
Answer:
y = 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
We know that a horizontal line has a slope of zero:
Slope m = 0
y = 0x + b
y = b
Since we are trying to find a line that fits with (-1, 3), we look solely at the y-value.
y = 3
We want to find the equation of a horizontal line such that it passes through a given point.
The answer is: y = 3
We know that the general form of a horizontal line is:
y = a
Where a is a real number.
Now, we also want that our line passes through the point (-1, 3).
Notice that the y-value of the point is 3, and in a horizontal line we can have only one value of y, so the horizontal line must be:
y = 3
The graph of the line and the point can be seen below
