Answer:
[-2,4]
Step-by-step explanation:
The domain is just asking for all the possible x values
we can see that the lowest x value is -2 and the highest is 4 which means our answer is
[-2,4]
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the
x
-axis. The range is the set of possible output values, which are shown on the
y
-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.
We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

Answer:
es 8 ksnfjskausksufbab 726+47272774
Answer:
(x. y) =(4, 7)
Step-by-step explanation:
-7 x - 2 y = 14
6 x + 6 y = 18
Solve the equation
x = - 2/7 y
6 x + 6 y = 18
Substitute the value of x
6 ( - 2 - 2/7y) + 6 y = 18
Solve the equation
y = 7
Substitute the value of y
x = - 2 - 2/7 x 7
Solve the equation
x = - 4
A possible solution is
(x, y) = (- 4, 7)
Check the solution
- 7 x ( - 4) - 2 x 7 = 14
6 x ( - 4) + 6 x 7 = 18
Simplify
14 = 14
18 = 18
The ordered pair is the solution
(x, y) = ( - 4, 7)
Boom!

Step-by-step explanation:
Given
As the equation is given by
[tex]-5=b-2.3[/tex]
To determine
Solve the equation for b
Given the equation
[tex]-5=b-2.3[/tex]
switch the sides
[tex]b-2.3=-5[/tex]
Add 2.3 to both sides
[tex]b-2.3+2.3=-5+2.3[/tex]

124 students played a sport in the fall, and 76 students played a sport in the spring. What was the percent decrease of the students who played sports in the spring? Round your answer to the nearest tenth of a percent.
Answers
Answer:
5.7%
Step-by-step explanation:
subtract 124-76.
then, you would divide 76 by 124 to get a weird number so multiply that by 100 to get this.
5.64516129.
then rounding to the nearest tenth would be 5.7.
so i think it would be 5.7%.

Given a term in an arithmetic sequence and
the common difference find the 100th term.
a14= 102
d = 10
Please help, i’m struggling.
Answers
Answer:
100th term = 962
Step-by-step explanation:
You need to find the first term of the sequence
The formula to use is
[tex]a_{n} = a_{1} + (n - 1)d[/tex] In your problem, n = 14. So,
[tex]102 = a_{1} + (14 - 1)10\\102 = a_{1} + 130\\a_{1} = -28\\\\[/tex]
Now you can find the 100th term. n = 100, first term = -28 and d = 10
[tex]a_{100} = -28 + (100 - 1)10\\ = -28 + 990\\ = 962[/tex]
100th term = 962
