Answer:
Pasta: $2.39
Jar of tomato sauce: $3.09
Coupons(-): $0.75+$0.50
Total cost: $4.23
Step-by-step explanation:
The total cost of Barry's purchase is the addition of the cost of purchase of pasta and a jar of tomato sauce, and the value of coupons is reduced from the answer. It would be the final answer.
Answer:
Check the attached graph
Step-by-step explanation:
Given equation is .
Now we need to graph the given equation ..
Clearly it is not linear as equation is not of the form . So we need to find some points on given equation . by plugging some random values of x like -5,-3,1,... etc.
for x=-5, we get:
.
Hence first point is at (-5,-2). Similarly we can find more points and graph those points.
x can't be 0 as division by 0 is not defined so it will have vertical asymptote at x=0.
Since degree of numerator is less than degree of denominator so y=0 will be horizontal asymptote.
Now join those points by a curved line to get final graph.
Hi! I don’t know what any of this means but I just wanted to tell you that I hope you have an amazing day and god/allah/etc bless you :)
