Answer: the number is 9
Explanation:
4x - 9 = 27
Add 9 to both sides:
4x = 36
Divide both sides by 4:
x = 9
Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
Answer:
42.3
Step-by-step explanation:
add both angles then subtract by 180 and the negative number is your answer
If they do not have a line of best fit this may be because there is no correlation
