Answer:x=-3
Step-by-step explanation:
Factor and set each factor equal to zero.
Hi!
First, let me explain that open circles mean that the answer starts after or before that number. So if the answer is c < 4, the answer would be D, and not B.
If the answer was c ≤ 4, the answer would be B, and not D.
I hope that makes sense. Now let's solve the inequality.
Remember that whatever we do to the inequality, we have to do it to both sides.
We need to isolate c on one side.
10c + 5 ≤ 45
Start by subtracting 5 from both sides.
10c + 5 - 5 ≤ 45 - 5
10c ≤ 40
Divide by 10 on both sides.
10c/10 ≤ 40/10
c ≤ 4
The answer is B.
Hope this helps! :)
Measure = 1/2 (120-30)
1/2(90)
45
Answer = 45°
With respect to the parent function y = cos x, the interval closest to the range of the transformed function is ( 0,50). the correct option is D.
<h3>How to find the functions corresponding to each graph based on the period of a function?</h3>
Mathematically speaking, cosines are periodic functions, and period (T) is the distance in the horizontal axis such that f(t + T) = f(t). The period of the parent cosine function is 2π. The period in daughter functions may vary by means of the following form:
y = cos Ax (1)
Where:
x - Independent variable
y - Dependent variable
A - Period width
From the graph, it is observed that with respect to the parent function y = cos x, the interval closest to the range of the transformed function is ( 0,50). the correct option is D.
