ANSWER
B. 1
EXPLANATION
The given function is

This is a piece-wise defined function.
We want to find f(1)
We substitute x=1 into f(x)=x because, 1 belongs to the interval,
1≤x≤5
f(1)=1
The correct answer is B.
Answer:
153.9380400259 in2
Step-by-step explanation:
I don’t wanna give the exact answer, i want to help you and lead you in the right place so you know the concept and process if a similar question is on an assessment. basically, the set of equations is set up for substitution method. we can agree that y equals 3x-3. so in the second equation, instead of writing “2y” you would SUBSTITUTE the y for 3x-3. so the equation would be 2(3x-3)-x=4. do the distributive property. once you get the equation after doing the distributive property, you solve for x using your algebra skills from previous units (cancel out x’s, for instance). your answer is your x coordinate. in order to find your y, you substitute whatever number you got for x and plug it in to one of the equations, doesn’t matter which. you will then solve for Y using your algebra skills you learned from previous units. after solving, you should get what y=. now you put the number in coordinate pair form which is (x,y)
Answer:
(2,-4)
Step-by-step explanation:
(2,4) is located in Quadrent I (+,+), if you reflect over the x-axis, it would be in Quadrent IV (+,-).
if you dont understand I suggest you draw a coordinate plane on a graphing notebook.
