You can solve this problem by using the Gauss method. The Gauss method is a method where you can add the first and last numbers together, and then multiply by how many times that appears. Here, the sum of the first and last number is -11. In this sequence, it would appear ten times (since there are ten terms and the terms are used twice in every eleven). -11 * 5 is -55, so that means the answer to this question is -55.
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.
The domain is the values of x between 1 and 7
The range
A straight line is 180°. 180°-135°=55°, so x=55°, which is an acute angle because it is less than 90°.
Answer:
x=30
Step-by-step explanation:
5x+x=180
6x=180
x=30
5x=150
x=30
3x=90
2x=60
Answer:
x = 9
Step-by-step explanation:
Distribute
2x+2*5=3x+1
2x+10=3x+1
Subtract 3x from both sides
-x+10=1
Subtract 10 from both sides
-x=-9
Multiply both sides by -1
x=9
