You would need 27 more dollars because f(x)=7x+2 plug in the 5 in x’s spot and you get 37 and so subtract it from 10 to get 27
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> room has square dimensions and it has been built with two pieces of sheetrock, a smaller one and a larger one.
2. Therefore, let's call
x: the smaller one.
y: the larger one.
3. Then, you have that the lenght of the wall is the sum of the smaller one and the larger one:
x+y
4. So, the area of the room is:
(x+y)(x+y)
(x+y)</span>²
Therefore, the answer is: (x+y)²
Graph the inequality y> 2x +3
Solution
<u>Step 1: </u>To graph the inequality, we need to find a few coordinates and form the table.
<u>Step 2:</u> Forming the table.
Let's take x = -1 and find the value of y.
Plug in x = -1 and find the value of y.
y = 2(-1) + 3 = -2 + 3 = 1
When x = -1, the value of y is 1.
So the coordinates are (-1, 1)
Plug in x = 0 and find the value of y.
y = 2(0) + 3 = 3
The coordinates are (0, 3)
Plug in x =1 and find the value of y.
y = 2(1) + 3 = 2 + 3 = 5
The coordinates are (1, 5)
<u>Steo 3: </u>Now let's plot the points and draw the graph.
Since the graph is greater than, we have to draw the dotted lines and shade the region above.
Note: You can find the graph in the attachment.
Thank you :)
Answer:
T={...,-3,-2,-1,0,1,2,3,4,....}
Step-by-step explanation:
We are given that T={5a+2b; a,b belongs Z}
We have to rewrite the given set T as a list of its elements
Substitute a=0 and b=0
Then we get 5(0)+2(0)=0
Substitute a=-1 and b=2 then we get
5(-1)+2(2)=-1
Substitute a=2 and b=0
Then , 5(2)+2(0)=10
If a=0 and b=1
Then, 5(0)+2(1)=2
Substitute a=0 and b=2
Then, 5(0)+2(2)=4
If substitute a=1 and b=1
5(1)+2(1)=7
If substitute a=-1 and b=3
Then, we get 5(-1)+2(3)=1
Then, T={...,-3,-2,-1,0,1,2,3,4,....}
Answer:
The coefficient of determination!
Step-by-step explanation:
It shows percentage variation in the target variable (y)y which is explained by all the predictor variables (X) together. It is always between 0 and 1. Hope this helps :)
