Answer:

1 1/4

Step-by-step explanation:

2 1/2 - 1 1/4

We need to get a common denominator of 4

2 1/2*2/2 = 2 2/4

2 2/4 - 1 1/4

I like to line them up vertically

Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the lar
Talja [164]
To solve this problem, simply use one variable to represent the number of students in each of the 2 classes.

1st class - X = no of students
2nd class - X + 6 no of students

Both classes : X + X + 6 = 50
2X + 6 = 50
2X = 44
X = 22.

1st class - X = 22 students
2nd class - X + 6 = 22 + 6 = 28 students.

There are 28 students in the larger class.

F(x) = 2x2 − 5x + 3
eduard

Answer:

part A: The x-intercept of the graph is the point where the function crosses the x-axis. for f(x)=2x2-5x+3 its (1,0)

part B= If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.  

(5/ 4 , − 1 /8 ) is the vertex for  f(x)=2x2-5x+3

The population of a city in 2005 was 18,000. By 2010, the city’s population had grown to 45,000. Economists have determined that
tensa zangetsu [6.8K]
2005= 18,000
2010= 45,000


1) make 2005 year "0", and 2010 year "5"
2)in order to solve this problem and figure out the rate of change, we must use the equation for exponential functions y=ab^x
3) a= the y- value of y intercept ( what does y equal when x is zero) in this case a population number so, a= 18,000; b= the unknown rate of change; x= time and since we're finding  b we can plug in 5 for the time in years; y= the value of y in terms of the x-value, so when x is 5, y is 45,000
4) you end up with something like this
45,000= 18,000b^5
5) in order to proceed to solve you must get b alone
6) divide both sides by 18,000
7) so you no have 2.5= b^5
8) take the fifth root of both sides 
9) now you have your answer b=<span>1.20112443398</span>

Answer:

156

Step-by-step explanation:

While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.

Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.

2)9*2=18 -> 18*2=36

3)192-36=156.
