Y =14 in the first equation , and in the second equation its y=8
Answer:
Step-by-step explanation:
So you have a constant value of 5 dollars and a variable value of 1.50 dollars. some equation of these numbers equals 23 dollars. That equation is
23=5+(1.50n) where n is the number of booster packs.
Answer:
value of x = 3
Step-by-step explanation:
here's the solution :-
=》f (x) = 4x + 5
and we know,
=》f (x) = 17
so, by equating both equations, we get :-
=》4x + 5 = 17
=》4x = 17 - 5
=》x = 12 ÷ 4
=》x = 3
Answer: x= 0.3 or x=3/10
Step-by-step explanation:
90x=27
divide both sides by 90
x=27/90 which simplfiyes to 3/10
x=0.3
You have to complete the squares on both the x terms and the y terms in order to solve this. Move the 20 over to the other side so it's negative. Group the x terms together and complete the square to get (x^2+2x+1) and then do the same with the y terms: (y^2-4y+4). You have to add 1 and 4 to other side with the 20 to get a 25. Then create 2 perfect square binomials within each x and y value to get the vertex coordinates: (x+1)^2 + (y-2)^2 = 25. This tells us that the vertex is located at (-1, 2) and the radius is the square root of 25 which is 5.So the answer is the first choice above.
