Answer:
We need to know what the program is...
Step-by-step explanation:
This question is literally unanswerable as some programs last 2 seconds and some would last thousands of years. More context as to what the program is please.
3x + 2y = 19
x + y = 8
3 (x + y) = 3 (8)
3x + 3y = 24
3x + 2y = 19
-
3x + 3y = 24
--------------------
-y = -5
y= 5
x + y = 8
x + 5 = 8
x = 3
(3, 5)
Answer:
Relation only.
Step-by-step explanation:
it is not a function because there is a repeated -2 in the x-values of the ordered pairs.
Answer:
3. Acute and scalene
5. Acute isosceles
Explanation:
Those are the two answers that had mistakes
Answer: y = -1, y = 6 (choice D)
===========================================================
Work Shown:
y - (6/y) = 5
y*(y - (6/y)) = y*5 <<--- see note 1 below
y^2 - 6 = 5y
y^2 - 5y - 6 = 0
(y+1)(y-6) = 0 <<--- see note 2 below
y+1 = 0 or y-6 = 0
y = -1 or y = 6 which are the two answers
note 1: I multiplied both sides by y to clear out the fraction (the LCD is y)
note 2: I factored the left side by asking myself "what two numbers multiply to -6 and add to +5?" the answer to that question is +1 and -6 which helps lead to the factorization. An alternative route instead factoring is to use the quadratic formula
