To solve this we would need to make two equations. One equation accounts for the number of hot dogs and sandwiches and the other is the total cost
X + Y = 985
2.95x + 9.95y = 7343.75
Solve for one variable and plug it into the other equation. And solve for the next variable.
X = hotdogs
Y = sandwiches.
The value of x is 12. The angles are supplementary and add up to equal 180. Solve for x and you'll get 12. Hope this helps!
Answer:
f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2
Step-by-step explanation:
For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.
For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.
Answer: The triangle mentioned here is an acute angled triangle.
Step-by-step explanation: x+x+10+2x-6=180°(angle sum prop. of triangles)
= 4x+4=180°
= 4x=174°
= x=44°
therefore, x=<u>44°</u>
,x+10=44+10=<u>54°</u>
,2x-6=2(44)-6=<u>82°</u>
