We are given with the inequality |2x + 1| ≤ 5 and asked to solve the equation. In this case, we take first the positive side, that is 2x + 1 ≤ 5. this is equal to 2x ≤ 4 or x ≤ 2. For the negative side, the equality is -5 ≤ 2x + 1. This is equal to -6 ≤ 2x or -3 ≤ x. Hence the solution is -3 ≤ x ≤ 2. The answer is B. closed dots on -3 and 2 with shading in between. The equal in <span>≤ means closed dots.</span>
I think I might have my math wrong here but I think 5
Answer:
82.4 cm
Step-by-step explanation:
The computation of the height is given below:
As we know that each right triangle contains the top angle of 20 degrees
So, the right angle & the bottom corner angle equivalent to
= 180 - 90 - 20
= 70 degrees
Now the height is
tangent = opposite leg ÷ adjacent leg
tan (70°) = height ÷ 30 cm
height = 30 cm × tan (70°)
= 82.4 cm
I positive 15 and negative 15, in effect the absolute value function just removed negative signs
Answer:
1 a. warmer
b. -8 is closer
c. -2 degrees
d.his elevation is 10 ft below sea level
2 a.0
b. -300
c. -450
3 Basically a fraction is division so divide the numerator by the denominator to get the calculation. For example 2.1 divided by 1.5 equals 1.4.
