a.
b=cost per burrioto
t=cost per taco
b.
3 burritos and 4 tacos costs 11.33; 3b+4t=11.33
9 burritos and 4 tacos costs 22.07; 9b+4t=22.07
c. solve
3b+4t=11.33
9b+4t=22.07
mulitply irst equation by -1 and add to 2nd to cancel t's
-3b-4t=-11.33
<u>9b+4t=22.07 +</u>
6b+0t=10.74
6b=10.74
divide both sides by 6
b=1.79
subsitute back
3b+4t=11.33
3(1.79)+4t=11.33
5.37+4t=11.33
4t=5.96
divide both sides by 4
t=1.49
solution: 1 taco costs $1.49 and 1 burrito costs $1.79
Answer:
y = csc (x) + 2
Step-by-step explanation:
From the graph, we can derive the parent function y = csc(x). Notice how there are asymptotes at x = 2πk and x = π + 2πk, which is where csc(x) is undefined.
Finally, we can see a vertical shift of 2 which we can see from the mid-line of the graph which is at y = 3.
Answer:
The value of the expression = 200
Step-by-step explanation:
The given expression is 
Using the low of exponent 
So, the expression =
<u>So, The value of the expression = 200</u>
5x+y2
=15+4
=19
So 19 is the answer.
