Which statements include two quantities in the real world that are additive inverses?

select each answer that is correct.

a. a hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.

b. noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.

c. daniella overdraws her account by $70 and then deposits $100 in the account.

d. a lithium ion has 3 positively charged protons and 2 negatively charged electrons.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

b.-4 units

all you   do is count how many times you move

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
