Step-by-step explanation:
The formula for percent change is
change/original.
So let's subtract 17 from 55 to find the change. 55-17=38
This is the change. Now we divide it by the original, 17.
38/17=2.235294
We're not done yet! We have to move the decimal point over to the right 2 spaces to make it a percentage. So, the percentage increase is
about 223.53 percent
Solve x2 + 10x = 24 by completing the square. Which is the solution set of the equation? {–12, 2} {–2, 12}
Answer: I could be wrong so don't get your hopes up but I believe the solution set would be {-2,12}
Step-by-step explanation:
Answer:
The solution set is {-12,2}.
Step-by-step explanation:
We have given a quadratic equation.
x² + 10x = 24
We have to find the solution of above equation by completing square.
Adding (5)² to both sides of above equation, we have
x²+10+(5)² = 24+ (5)²
(x+5)² = 24+25
(x+5)² = 49
Taking square root to both sides of above equation, we have
x+5 = ±7
x+5 = 7 or x+5 = -7
x = 7-5 or x = -7-5
x = 2 or x = -12
Hence, the solution set is {-12,2}.

Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1
The graph of g(x), shown below,is a vertical shift of the graph f(x)=3^x write the equation for g(x)
Answer: OPTION D
Step-by-step explanation:
By definition, an exponential parent function (The simplest forn of an exponentil function) has the following form:
[tex]f(x)=b^x[/tex]
When an exponential function has the form [tex]f(x)=b^x+k[/tex], means that this is shifted k units up.
Therefore, keeping the above on mind, you can conclude that the equation of the function g(x) is the shown below:
[tex]g(x)=3^x+1[/tex]

Step-by-step explanation:
Solve the equation for y. 2x + 5y = 5
Answer:
see explanation
Step-by-step explanation:
given
2x + 5y = 5 ( isolate the term in y by subtracting 2x from both sides )
5y = 5 - 2x ( divide both sides by 5 )
y = [tex]\frac{5-2x}{5}[/tex]
To solve 2x + 5y = 5 for y, subtract 2x from both sides and then divide by 5 to get y = 1 - (2/5)x.
To solve the equation 2x + 5y = 5 for y, we need to isolate y on one side of the equation. Here are the steps to do it:
Subtract 2x from both sides of the equation to get 5y = 5 - 2x.Divide both sides of the equation by 5 to solve for y, which gives us y = (5 - 2x) / 5.Therefore, the solution for y in terms of x is y = 1 - (2/5)x.

A student did a survey on how people feel when they are hungry. The results were that more people felt a stabbing pain than their stomach aching. 30 people said that their stomach ached when they were hungry. 49 people said they felt a stabbing pain. How many more people felt a stabbing pain than stomach aches?
it’s 19 :)
filler

hi
The number of more people who felt a stabbing pain than a stomach ache when they are hungry is obtained by subtracting the number of people who felt a stomach ache from the number of people who felt a stabbing pain. The difference, which is 19, indicates that 19 more people felt a stabbing pain.
Explanation:The subject of the question is simple subtraction in mathematics. In this scenario, find the difference between the number of people who felt a stabbing pain when they were hungry and the number who felt a stomach ache. The number of people who felt a stabbing pain is 49, and the number of people who felt a stomach ache is 30. So, to obtain the number of more people feeling stabbing pain than stomach ache: 49 (stabbing pain) - 30 (stomach ache) = 19. Thus, 19 more people felt a stabbing pain than a stomach ache when they were hungry.

What is the average size of the lots?
______acre
i know how to do a line plot just can't figure the answer out.
Final answer:
To find the average size of the lots provided, organize the information in a line plot and calculate the average by summing the areas of the lots and dividing by the total number of lots.
Explanation:
Line Plot:
Average Size of Lots:
1/6 acre (3 lots)
1/2 acre (6 lots)
1/3 acre (3 lots)
To find the average size, add the areas of all lots and divide by the total number of lots. In this case, the average size of the lots would be 17/36 acre.

Tell whether the given ordered pair is a solution of the equation 4y + 2x = 3; (1.5,0)
Answer:
Yes, it is a solution
Step-by-step explanation:
Plug the given (x, y) point of (1.5, 0) into the equation to find out...
4(0) + 2(1.5) = 3
0 + 3 = 3
3 = 3
The given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.
What does the solution of an equation mean?The solution of an equation, when substituted makes the left-hand side equal to the right-hand side. It is the value for which the LHS = RHS.
We can determine whether the ordered pair is a solution as shown below:The equation is 4y + 2x = 3.
The given ordered pair is (x,y) = (1.5,0). Now substitute the values of x and y.
4y + 2x = 3
⇒ 4(0) + 2(1.5) = 3
⇒ 0 + 3 = 3
⇒ 3 = 3
Therefore, we have determined that the given ordered pair (1.5,0) is a solution of the equation 4y + 2x = 3.

a point occupies zero dimensions true or false
Answer: True.
Step-by-step explanation:
In geometry , we have three undefined terms as :
1) point [ no dimension]
2) line [ one dimension]
3) plane [ two dimension]
A point is just a tiny mark on Cartesian plane which has no length like a line , no width and area like a plane or no volume like a three dimensional shape . We can use only its location but cannot measure it.
Hence, it has no dimension.
Hence, the given statement "a point occupies zero dimensions" is a true statement.
