Answer:
The answer to the equation from question 7 is 14.
Step-by-step explanation:
In question 7, we are given an equation.
2³ + (8 - 5)² - 3
First, subtract 5 from 8 in the parentheses.
2³ + 3² - 3
Next, solve the exponents for 2³ and 3².
8 + 9 - 3
Add 8 to 9.
17 - 3
Subtract 3 from 17.
14
So, the answer to this equation from question 7 is 14.
Answer:
x+120 , if x < -120
x+12 , if x > -12
x+12 , if x < -12
x+12 , if x = -12
x÷3 , if x > 0
x÷3 , if x < 0
Step-by-step explanation:
Well whatever is in the absolute value sign is always positive.
Answer:
it should be 245.6
Step-by-step explanation:
since it was 2decimal place we move the point 2times forward and it becomes 245.6
Answer:
B
Step-by-step explanation:
The problem wants you to PLUG IN x into the correct equation.
1) f(-1) means -1 equals x
f(3) means 3 equals x
For example g(9) means 9 = x and f(3/5) means 3/5 = x and so on.
2) Now that you know x equals two numbers -1 and 3 you have to plug them into a equation.
3) Which equation do you plug it in you may ask? You must plug in -1 into x^2 +3 BECAUSE the condition next to it says you can only plug in numbers to x^2+3 greater than or equal to -1 and less than 2. Therefore, you can plug in -1 to this equation.
-1^2 +3 = <u>4</u>
4) Now you have the number 3. Where do you think we should plug #3 into? Well you can plug it in to the first equation because the condition only allows numbers less then -1. the only option is the last one!!
1, for x >= 2 because 3 is certainly bigger than 2.
This means any number greater than or equal to 2 has to be 1.
SO OUR ANSWER IS 4 AND 1
Do I understand coorectly, you have the following equation
6x+1=4x+19
and you want to know what x is?
first, let's put all the expressions with x on one side and all else on the other side:
6x-4x=19-1
and calculate this 2x=18
and divide by 2:
x=9
and this is the answer!
