Ok, find the relationship between 16 and 100, which is 6.25. Now multiply that by 12 and get 75. Your answer is 75/100
1- a=2
2- a=2
3- a= 0.107309 I screenshot the answer for this one with steps included. Hopefully it helps.
Okay. It would be written like this: n/7 - 2 = 10. Add 2 to both sides and then you get n/7 = 12. Multiply by 7 to isolate the “n”. Then, you should get n = 84. Plug it in. 84/7 is 12. 12- 2 = 10. There. n = 84.
Answer:
Vertex (-3,1)
Step-by-step explanation:
y = x^2 + 6x + 10 Put brackets around the first two terms
y = (x^2 + 6x) + 10 Take 1/2 the linear term (6) and square it. Put that inside the brackets. Always add.
y = (x^2 + 6x + (6/2)^2 ) + 10 Since you added in side the brackets, subtract after the 10
y = (x^2 + 6x + 9) + 10 - 9 The 3 terms inside the brackets are a perfect square. Combine the two terms outside the brackets.
y = (x + 3)^2 + 1
The vertex is at (the value that makes x + 3 go to zero, and the number outside the brackets)
(-3,1)
Check
The check is to ask Desmos to graph the equation. That graph is shown below. Notice that the lowest point is(-3,1). Notice that the graph and my answer do agree.
