Answer:
x= -3/2
Step-by-step explanation:
You would multiply both sides by 6x+10 and then that would give you 5-5)6x+10) and you would divide both sides by 5. This would give you 1=6x+10, you would then try to isolate the 6x giving you -6x=10-1 or -6x=9 and you would see if the solutions are in the defined ranges so x=-5/3 is NOT in the defined range but x=-3/2 is.
<span>The event definition that corresponds to exactly one outcome of the experiment is that both numbers are 5s.</span>
Id take a guess and say line 1 because the rest looks correct
This can be solved using a ratio. The ratio is: 13/20=x/60 this would then become 20x= 780 divide both sides by 20 and you get x=39. the answer is 39
Answer:
Step-by-step explanation:
Zeros α = -3 and β = -4
Quadratic equation: x² - (α + β)x + αβ = 0
x² - (-3-4)x + (-3)*(-4) = 0
x² - (-7)x + 12 =0
x² + 7x + 12 = 0
