Answer:
x ≥-3
Step-by-step explanation:
7 − 9x − (x + 12) less than or equal to 25
7 − 9x − (x + 12) ≤ 25
Distribute the minus sign
7 − 9x − x - 12 ≤ 25
Combine like terms
− 10x −5 ≤ 25
Add 5 to each side
− 10x −5+5 ≤ 25+5
− 10x ≤ 30
Divide by -10. Remember that this flips the inequality
− 10x/-10 ≥30/-10
x ≥-3
The last one!
Step-by-step explanation:
2^3 is 8 which makes it the greatest value
the radical 4 is 2
the 54% is equal to .54 in decimal form
the 0.030 is the value with the least
Answer:
x = 2+1/3i or 2-1/3i
Step-by-step explanation:
The equation of interest can be written in vertex form as ...
9(x -2)² +1 = 0
so its solutions can be found by subtracting 1, dividing by 9, taking the square root, then adding 2.
x = 2 ± √(-1/9)
In the desired form, the zeros of the given expression are ...
x = 2 +1/3i or 2 -1/3i
My work shown is how to get x. now that you have x plug it into the equation.
To test your answer add both 51 and 39, and you should get 90 (the measurement of a right angle)
88 multiplied by 106 is 9328 and move two decimal spaces to the left wich is 93.28% :)
