Answer:
D
Step-by-step explanation:
The domain of a graph is its horizontal extent. It is all the values of x for which a function value is defined.
__
This graph shows a relationship that is defined from x=0 to x=7. It is not restricted to integer values of x. The domain is ...
real numbers from 0 to 7.
Answer:
he forgot to put the decimal point
Step-by-step explanation:
answer is 1.05.
Q1
I like to use the standard form to write the equation of a perpendicular line, especially when the original equation is in that form. The perpendicular line will have the x- and y-coefficients swapped and one negated (remember this for Question 3). Thus, it will be
... 5x - 2y = 5(6) - 2(16) = -2
Solving for y (to get slope-intercept form), we find
... y = (5/2)x + 1 . . . . . matches selection C
Q2
The given equation has slope -3/6 = -1/2, so that will be the slope of the parallel line. (matches selection A)
Q3
See Q1 for an explanation. The appropriate choice is ...
... B. 4x - 3y = 5
Q4
The given line has slope -2, so you can eliminate all choices except ...
... D. -2x
Q5
The two lines have the same slope (3), but different intercepts, so they are ...
... A. parallel
3/5 + 5/7 = 1 11/35 - 1/5 = 1 4/35 which is your final answer.
