Answer:
Or if you want with the value of h too.
Step-by-step explanation:
Find the value of h and k by using the formula.
From y = x²-2
Substitute these values in the formula.
Therefore, h = 0.
Therefore, k = - 2.
From the vertex form, the vertex is at (h, k) = (0,-2). Substitute h = 0, a = 1 and k = -2 in the equation.
These type of equation where b = 0 can also be both standard and vertex form.
Answer:
False
Step-by-step explanation:
To find <A, we can do 5x - 80 = 3x + 20.
As we simplify, we will get 2x = 100, which is x = 50
Therefore, <A will be 50 degrees and not 45 degrees.
Also, if you need y, you can do:
3y - 7 = y + 7
2y = 14
y = 7
Answer:
Step-by-step explanation:
One third
Answer:
3/7=€24/? 24*7/3? Therefore Hannah received €56 as tip.
Step-by-step explanation:
Answer:
y(1) = 7
y(2) = 10
y(3) = 13
Step-by-step explanation:
y = 3(1) + 4
y = 3 + 4
y = 7
y = 3(2) + 4
y = 6 + 4
y = 10
y = 3(3) + 4
y = 9 + 4
y = 13
