The height of tower a is 854 feet more than tower b. the two towers have a combined height of 1,662 feet. what are the heights of each tower

Tower A: 1258

Tower B: 404

Step-by-step explanation:

Since we don't know the height of tower B, let's call that x.

So, the height of tower A is x+854.

and the equation for both towers together is x+x+854=1662

or 2x+854=1662

Now subtract 854 from both sides then divide by 2 to get x=404.

So, Tower B is 404 feet tall and Tower A (404+854) is 1258 feet tall.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
