Answer:
Step-by-step explanation:
x^2 + 3x - 1 + 3x
x^2 + 6x - 1 is the solution
Answer:
y = 1/2x - 5
Step-by-step explanation:
I'm going to use slope-intercept form. Your y-intercept is already shown when x is zero, which is (0,-5). Your slope is defined as rise over run, so 1/2 in this case. This gives you an equation of f(x) = 1/2x-5
Answer:
2 mph
Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
If s is the speed going up the mountain, then s+1 is the speed coming down. The total trip time for 6 miles up and 6 miles down is ...
6/s +6/(s+1) = 5
6(s+1) +6s = 5(s)(s+1)
5s^2 -7x -6 = 0 . . . . subtract the left side, simplify to standard form
(s -2)(5s +3) = 0 . . . . factor
s = 2 or -3/5 . . . . values that make the factors 0
Their speed was 2 miles per hour going up the mountain.
__
<em>Check</em>
It took 6/2 = 3 hours to go up the mountain, and 6/(2+1) = 2 hours to come down, for a total of 5 hours.
Answer:
Option B) The additive inverse of -3 is +3, so
Step-by-step explanation:
We are given the following expression in the question:
Additive Inverse:
- The additive inverse of a number a is the number when added to the original numbers it gives a sum of zero.
- Let x be a number, then additive inverse of x is -x
Additive Inverse of -3 is 3
Option B) correctly explains the given statement.
Opion B)
The additive inverse of -3 is +3, so
