Answer:
Step-by-step explanation:
(5y+4+3x)(5y+4-3x) = (5y+4)² - (3x)²......(from the difference of 2 squares )
by identity : (a+b)(a-b) = a² - b²
in this exercice ; a = 5y+4 and b = 3x
Answer:
The value of 4 is an input of the function
Step-by-step explanation:
Let
x -----> the independent variable or input value
y ----> the dependent variable or output value
we know that
Looking at the graph
The domain (input values) of the linear function is equal to the interval
[1,∞)

All real numbers greater than or equal to 1
The range (output values) of the linear function is equal to the interval
(-∞,3]

All real numbers less than or equal to 3
therefore
The value of 4 is an input of the function
Answer: 75%
Step-by-step explanation:
15/20 = 3/4 or 75%
Answer:
40
Step-by-step explanation:
The frequency column gives the number of houses in the sample, then
number of houses = 5 + 11 + 23 + 1 = 40
173, 400
49% of people do not run; thus, 51 percent of people do.
51% * 340,000 = 173, 400
