Okay so start with getting the x by itself
tan46 = x/12
multiply both sides by 12
12tan46 = x
put that into a calculator and you get:
x=12.4
Answer:
Is this a which ones wrong question because I think mayas wrong
Step-by-step explanation:
Y = x^2 - 6x + 7
a = 1
b = -6
c = 7
Before you get the A.O.S, you must first solve for the vertex.
The vertex formula is \frac{-b}{2a}
Plug in the numbers:
-(-6) / 2(1)
--6 = 6 and 2*1 = 2
6/2
Vertex (or x) = 3
Now you have to plug in the x in order to find the vertex (or y)
Your equation should now look like this;
y = (3)^2 - 6 (3) +7
Solve each part separately and then add it up...
3^2 = 9
-6 * 3 = -18
+7
9 - 18 + 7
A.O.S (or y) = -2
Answer:
18
Step-by-step explanation:
(5/6)x – 4 = 11
(5/6)x = 11 + 4
(5/6)x = 15
5x = 15×6 = 90
x = 90/5 = 18
ANSWER
$12.56
EXPLANATION
Orange costs $3.42 for 9 pounds.
We want to know how much it would cost to get 12 pounds of oranges.
To do this, we will simply compare and make our unkown x:
$3.42 = 9 pounds
x = 12 pounds
Now, we cross multiply:
=> x * 9 = 3.42 * 12
At this rate, 12 pounds will cost $4.56.
