Answer:
x ≤ 3
Just took the assignment, i hope you have a good day :)
Answer:
Step-by-step explanation:
From the graph attached,
Coordinates of points A, C and D are,
A(-2, -7), C(-6, 7) and D(9, 2)
Slope of AD = 
= 
= 
Slope of CD = 
= 
Slope of AC = 
= 
= 
<span>9.145 is the smallest value that will round to 9.15.
</span><span>As the rule that if that digit is less than 5, do not change the rounding digit but drop all digits to the right of it. So it should be 5 to 9 but then the question above is looking for the smallest possible number which is 5. </span>
Answer: x only can have complex values, not real values.
x = -1/4 - 1/4i and x = -1/4 + 1/4 i
Explanation:
Finding the possible values of x in the expression given is solving the quadratic equation.
8x² + 4x = - 1
Rearrange the terms:
8 (x² + x/2) = - 1 ← common factor 8 in the left side
x² + x/2 = - 1/8 ← division property
x² + x/2 + 1/16 = - 1/8 + 1/16 ← addition property
(x + 1/4)² = -1/8 + 1/16 ← -factor the perfect square trinomial in the left side
(x + 1/4)² = - 1/16 ← add the fractions in the right side
x + 1/4 = (+/-) √ (-1/16) ← square roots on both sides
x + 1/4 = (+/-) (1/4)i ← complex solution
x = - 1/4 +/- 1/4i
x = - 1/4 - 1/4i and x = - 1/4 + 1/4 i ← answer
Answer:
40600
Step-by-step explanation:
(4 * 10^4) + (6 * 10^2) =
= 4 * 10000 + 6 * 100
= 40000 + 600
= 40600
