2568.75 - 2500 = 68.75;
( ? / 100 ) * 2500 = 68.75 ;
? * 25 = 68.75;
? = 68.75 ÷ 25
? = 2.75;
r = 2.75 %
Answer:
5.15
Step-by-step explanation:
you add 3.50 and 1.65 to get the other number
Answer:
x= 50
Step-by-step explanation:
7/x = 14/100
14x = 700
x = 50
the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.
I hope this helped
To raise a function up by k units, add k to the whole function
f(x) is 2 units lower than g(x)
so -2 was added
k=-2
Answer:
a. 
b. x ≠ -5 (Vertical asymptote) and x ≠ 5 (Hole)
Step-by-step explanation:
Factor the numerator (Grouping):
Two numbers that multiply to -30 and add to -7 = -3 and 10
![[2x^2 - 10x] + [3x - 15]](https://tex.z-dn.net/?f=%5B2x%5E2%20-%2010x%5D%20%2B%20%5B3x%20-%2015%5D)

Factor the denominator (Difference of Two Squares):
= 
Factored Expression:
(x - 5) can be factored out of top and bottom as a hole-

Variable Restrictions:
Denominator ≠ 0

Vertical asymptote at x = -5 ⇒ x ≠ -5
