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
Answer:
Step-by-step explanation:
It is not a function
The 4 in the domain is used more than once
Answer:
-3
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have that Desiree wants to order 200 shirts that cost $5 and she <span> has $350 in her savings.
2. Keeping this on mind, the total cost of the shirts is:
</span>
3. Then, she must raise:
Therefore, the answer is: 
Red : Yellow
6 : 8
(÷6) (÷6)
1 : 8/6
1 : 4/3
therefore, R = 4/3Y
Answer: R = 4/3Y
