Answer: 3(x+9) = 12
Step-by-step explanation:
you can set up the equation as 3(x+9) = 12, since sum of x+9 multiply by 3 will equal 12, therefore you have that equation.
To solve for x:
3(x+9) = 12
x+9 = 4
x = -5
Answer:
y = f(x-2) + 1
Step-by-step explanation:
The original functions looks like f(x) = |x|
For the new function the vertex has shifted -2 left (x) and up +1 (y)
So
y = f(x-2) + 1
Answer:
The all solution of given trigonometrical equation is + 2πn .
Step-by-step explanation:
Given trigonometrical equation as :
7 - 14 sin x + 2 = - 5
Now, Rearranging the equation
7 - 14 sin x + 2 + 5 = 0
Or, 7 - 14 sin x + 7 = 0.
Taking 7 as common
So, - 2 sin x + 1 = 0.
∵The standard form of quadratic equation
a x² + b x + c = 0
So, breaking the mid term we get
- sin x - sin x + 1 = 0.
Or, sin x (sin x - 1) - 1 (sin x - 1) = 0
Or, (sin x - 1) (sin x - 1) = 0
Or, (sin x -1) = 0 and (sin x - 1) = 0
So, sin x = 1
∴ x =
i.e x = 90°
Or, ∠x =
And for all solution + 2πn , where n∈ 0 to ....
Hence, The all solution of given trigonometrical equation is + 2πn . Answer
