Answer:
Step-by-step explanation:
The first step in solving the equation is to cube both sides:
(∛x)³ = (-4)³ . . . . . = (-4)(-4)(-4) = 16(-4) = -64
x = -64 . . . . . simplified

We're not sure what "checking" is supposed to involve here. Usually, one would check the answer by seeing if a true statement is made when the answer is put into the original equation.
∛(-64) = -4 . . . true
Many calculators will not compute √(-64) because they compute roots using logarithms. The log of a negative number is not defined.
So, the way one would check this is to cube both sides, which is how we got the answer in the first place. We expect the same result from doing the same operation again, so it isn't really a check.
Answer:19.3
Step-by-step explanation:
96+28=124
6x+8=124
124-8=116
6x=116
116/6
x=19.3
Answer:
1/2
Step-by-step explanation:
Answer:
The value of T is 55°
Step-by-step explanation:
Using the theorem of parallel and equality,the angle of unknown angle equals to opposite one.
Or at least if you noticed,that angle is perpendicular,then 35+90=125;
180-125=55°
Answer:
Step-by-step explanation:
If you add a line of best fit, its extension is likely to intersect the y-axis between 200 and 100 but closer to 100.
The best estimate is choice C) 125
