Answer:
Step-by-step explanation:
for Which of the functions represents a linear function? Explain your reasoning, then determine the rate of change for that function over the interval 2≤x≤4.
For a linear function, the rate of change is represented by the parameter m in the slope-intercept form for a line: y=mx+b, and is visible in a table or on a graph.
its like 19.25 because thats the anwser and deal with it
(1) let there be x book and let the total cost be y dollars.
y=19.25x+40
y=16x+69.25
(2) 19.25x+40=16x+69.25
3.25x=29.25
x=9
9 silver book, 9 gold book.
(3) y=19.25x+40=19.25*9+40=213.25 dollars
both companies' total cost are 213.25 dollars.
Answer:
SAS congruence theorem
Step-by-step explanation:
since we are given the two congruent sides and the right angle. We know all right angles are congruent and the right angle is an angle that is between the two sides which is why it is SAS. hope this helps :))
X² -25 = 0
We can use formula a² -b² =(a-b)(a+b)
x² - 5² =0
(x-5)(x+5)=0
x+5 =0 or x-5 = 0
x=-5 or x=5
Answer is x=-5, x=5
