Answer:
x=11.6
Step-by-step explanation:
According to the angle addition postulate, if B lies on AC, than AB+BC=AC.
We can use this to create this equation.
x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.
The next step is to combine like terms, so we add 12 to 2.4 to get
x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.
x=11.6
Hope this helps. If you have any follow-up questions or I misunderstood the question, please tell me and I will fix it or explain more.
Have a great day! :)
Start by looking at the vertex form of a quadratic function, f(x) = a(x - h)^2 + k. The variables h and k are the values of the vertex. Plug those in to get f(x) = a(x - 4)^2 + 5. To find the variable a, plug in the point given for the x and y values. So, you get (21) = a((8) - 4)^2 + 5. Solve for a algebraically, and you get a = 1. Finally, plug everything in and simplify the equation. You should get that the quadratic function is f(x) = x^2 - 8x + 21. Hope this helps!
Solution
To find Which two numbers on the number line has an
absolute value of 3
Absolute value means " how far a number is from
zero " .
"3" is 3 away from zero .
and " -3 " is also 3 away from zero .
i.e
| 0 - 3 | = 3
| 3 - 0 | = 3
So , the absolute value of "3 " is 3
similarly , absolute value of "3 " is 3 .
Hence , the two numbers are -3 and 3
