Answer:
-4 and -3.
Step-by-step explanation:
Let the numbers be x and x+1.
From the given information:
x^2 + (x + 1)^2 + x = 21
x^2 + x^2 + 2x + 1 + x - 21 = 0
2x^2 + 3x - 20 = 0
(2x - 5 )(x + 4 ) = 0
x = 5/2 or -4 We ignore 5/2 as its not an interger
So the required integers are -4 and -3.
Answer:
B
Step-by-step explanation:
Lets start solving until we get stuck,
6|x|+25=15
Subtract 25 from both sides
6|x|+25-25=15-25
Subtract
6|x|=-10
Divide both sides by 6
6|x|/6=-10/6
Divide
|x|=-10/6
We get stuck here, we need x to be negative but we cant have a negative x since we have absolute value. This means the answer is b.
Answer: a) v=12 feet
b) 1: 12
2: 24
3: 36
4: 48
Step-by-step explanation:
A) v=d/t
They give you 60 feet, which can be plugged in for d (distance), and 5 seconds which can be plugged into t (time).
So, v=60/5=12
B) Kendall runs 12 feet per second, so in the chart:
1 sec x 12 feet = 12 feet
2 sec x 12 feet = 24 feet
3 sec x 12 feet = 36 feet
4 sec x 12 feet = 48 feet
