Answer:
46 mph
Step-by-step explanation:
Distance = speed x time
92 mi = speed x 2 hr
speed = 92/2 = 46 mph
Answer:
<em>m</em> > 6
Step-by-step explanation:
Move all terms not containing <em>m </em>to the right side of the inequality.
Inequality Form:
<em>m </em>> 6
Interval Notation:
(6, ∞)
Therefor, the answer would be:
<em>m </em>> 6
Hope this helps!
Answer:
x = 20
Step-by-step explanation:
3x + 6x = 180, if you make them supplementary then they will be parallel
9x = 180
x = 20
Answer:
(1,1) and (-2,-11) are the correct solutions
Answer: x = 6.32 or -0.32
Step-by-step explanation:
2x² - 6x + 10 = 0
No we divide the expression by 2 to make the coefficient of x² equals 1
We now have
x² - 3x + 5 = 0
Now we remove 5 to the other side of the equation
x² - 3x = -5
we add to both side square of half the coefficient of x which is 3
x² - 3x + ( ⁻³/₂)² = -5 + (⁻³/₂)²
(x - ³/₂)² = -5 + ⁹/₄
Resolve into fraction
(x - ³/₂)² = ⁻¹¹/4
Take the roots of the equation
x - ³/₂ = √¹¹/₄
x - ³/₂ = √11/₂
x = ³/₂ ± 3.32/₂
= 3+ 3.32 or 3 - 3.32
= 6.32 or - 0.32
