If ΔABC is an equilateral triangle with, AB = 2x + 17, BC = 6x - 19, AC = 4x-1, find x and the measure of each side
Soloha48 [4]

Answer:

x=9, AB=BC=AC=35

Step-by-step explanation:

Equilateral triangles have 3 congruent sides, so all 3 sides have the same length. Therefore, we know that AB=BC=AC. We are given the lengths of all 3 sides in terms of x, but we only need to set two of them equal to each other to solve for x. Let's use AB and BC to solve for x. We know that AB=BC, AB=2x+17, and BC=6x-19. Therefore, we can write the following equation to solve for

AB=BC\\2x+17=6x-19 (Substitute given values into equation)

Solving for x, we get:

2x+17=6x-19\\2x+17-17=6x-19-17 (Subtract 17 from both sides of the equation to isolate constants)

2x=6x-36 (Simplify)

2x-6x=6x-36-6x (Subtract 6x from both sides of the equation to isolate x)

-4x=-36 (Simplify)

\frac{-4x}{-4}=\frac{-36}{-4} (Divide both sides of the equation by -4 to get rid of x's coefficient)

x=9 (Simplify)

Therefore, AB=2x+17=2*9+17=18+17=35, and AB=BC=AC=35. Hope this helps!

A certain store is having a sale on all the items.All items are 15% off.In addition,you have a coupon for 100 pesos off in any i
Ilia_Sergeevich [38]

Answer:

f(x) = 0.85x

g(x) = 0.85x - 100

Step-by-step explanation:

Given that :

Sale price = 15% off the item price

Let original price = x

Hence, sale price = (100 - 15)%

Let the sale price function = f(x)

f(x) = 0.85x

Where, x = price before 15% off

Customer also has a coupon discount of 100 pesos

Let coupon discount price = g(x)

g(x) = f(x) - 100

Hence,

g(x) = 0.85x - 100

x = price before 15% off
