In order to find the distance between -61.5 and -23.4 on the number line, you just have to subtract either the greater value to lesser value or lesser value to the greater value. It doesn't matter when you get a negative difference because the distance should be the absolute value of the difference of two points on a number line.
Here's how you should do it.
(-61.5) - (-23.4) = -61.5 + 23.4 = l-38.1l = 38.1
or
(-23.4) - (-61.5) = -23.4 + 61.5 = l38.1l = 38.1
As you can see above, I tried to subtract the two numbers in different order, and the result is still the same. Just make sure to get the absolute value of the answer because the distance should always be in positive form.
Therefore, the distance between -61.5 and -23.4 is 38.1
2x^2 + 8x + 8
= 2(x^2 + 4x) + 8
= 2 [ (x + 2)^2 - 4) + 8
axis of symmetry is x = -2 ( because of the (x + 2)^2 )
Answer:
8
It is an isosceles triangle so the two sides are equal
Answer:
46 1/2 miles
Step-by-step explanation:
Given that:
Bus traveled at a constant speed ;
Miles traveled = 15 1/2 miles
Time taken for the travel = 1/3 of an hour
Number of miles bus will travel in 1 hours :
Let number of miles traveled in 1 hour = n
15 1/2 miles = 1/3 hour
n miles = 1 hour
Cross multiply :
1/3 * n = 15 1/2 * 1
1/3n = 31/2
Divide both sides by 1/3
n = 31/2 ÷ 1/3
n = 31/2 * 3/ 1
n = 93/2
n = 46.5 miles = 46 1/2 miles
