1st term a₁ = - 3.7; common difference d = - 1.3
the nth term a(n) = a₁ +(n-1)d or a(n) = 3.7 + (n-1)(-1.3)
a(n) = - 3.7 - 1.3n + 1.3 ====> -2.4 - 1.3.n Or as per your answer:
a(n) = -1.3.n - 2.4
Answer:
x° = 37°
Step-by-step explanation:
* Lets revise some facts of a circle
- The secant is a line intersect the circle in two points
- If two secants intersect each other in a point outside the circle,
then the measure of the angle between them is half the difference
of the measures of their intercepted arcs
* Now lets solve the problem
- There is a circle
- Two secants of this circle intersect each other in a point outside
the circle
∴ The measure of the angle between them = 1/2 the difference of the
measures of their intercepted arcs
∵ The measure of the angle between them is x°
∵ The measures of their intercepted arcs are 26° and 100°
- Use the rule above to find x
∴ x° = 1/2 [ measure of the large arc - measure of small arc]
∵ The measure of the large arc is 100°
∵ The measure of the small arc is 26°
∴ x° = 1/2 [100 - 26] = 1/2 [74] = 37°
∴ x° = 37°

i did not understant your question
i think u want the definition of relation
A relation between two sets is a collection of ordered pairs containing one object from each set. If the object x is from the first set and the object y is from the second set, then the objects are said to be related if the ordered pair (x,y) is in the relation. A function is a type of relation.

Answer:
Sub the values for x and y into the equations.
Step-by-step explanation:
x = 2
y = 1
Y = 2x - 3
1 = 2(2) - 3
1 = 4 - 3
1 = 1
Y = -½x + 2
1 = -½(2) + 2
1 = - 1 + 2
1 = 1
