Answer:
(20*(2+1)+3)/9 = 7
Step-by-step explanation:
You can tell that the only way that it can be true is using the division.
63/9 = 7
So I tried to find a way for everything before the grouping symbol to be 63:
(20*(2+1)+3)/9 = 7
Answer:
A reflects over the Y-axis, and B reflects over the x-axis.
Step-by-step explanation:
im a girl btw lol not a boy so sorry
E because you can add, subtract, multiply and divide from both sides of an equation. All of these options will work when solving for a solution set.
Hope this helps and have a great day

Answer:
y = 2x^2 +1
Step-by-step explanation:
This is a parabola so it is in the form
y = a( x-h) ^2 + k
where ( h,k) is the vertex which is at ( 0,1)
y = a (x - 0)^2 + 1
y = ax^2 +1
Pick another point on the graph to determine a
(1,3)
3 = a(1)^2 +1
Subtract 1 from each side
3-1 = a(1)
2 =a
y = 2x^2 +1
