Answer:

  • \bf x=7^o

Step-by-step explanation:

When two parallel lines are crossed by a transversal, co-interior angles They are called co-interior angles.  The sum of the two angles on the same side of the transversal is always 180°.

\bf 120^o+7x+11=180^o

\bf 7x+120+11=180

\bf 7x+131-131=180-131

\bf 7x=49

\bf \cfrac{7x}{7}=\cfrac{49}{7}

\bf x=7^o

Answer:

x = 7

Step-by-step explanation:

corresponding interior angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line

one is an obtuse and one is an acute angle in which sum up to 180°

(120°) + (7x + 11) = 180°

120° + 7x + 11 = 180°

131° + 7x = 180°

131° - 131° + 7x = 180° - 131°

7x = 49°

7x/7 = 49°/7

x = 7°

plug x in to check:

7(7) + 11 = 49 + 11 = 60

Show how the following sequences is an arithmetic or not <br>please help me ​
serious [3.7K]

Answer:

not arithmetic

Step-by-step explanation:

An arithmetic sequence has a common difference d between consecutive terms.

Given

T_{n} = 2n² - 1

Substitute in n = 1, 2, 3, 4 to generate the first 4 terms of the sequence

T_{1} = 2(1)² - 1 = 2 - 1 = 1

T_{2} = 2(2)² - 1 = 8 - 1 = 7

T_{3} = 2(3)² - 1 = 18 - 1 = 17

T_{4} = 2(4)² - 1 = 32 - 1 = 31

check the difference between consecutive terms

7 - 1 = 6

17 - 7 = 10

31 - 17 = 14

The differences are not common hence not an arithmetic sequence

The <em>y-intercept</em> would be 300

The slope would be -40

Step-by-step explanation:

x=number of months

300 is the amount she starts with

Equation can also be written like so;  y=-40x+300 just like in y=mx+b (slope intercept) form
