a student bought a juice pouch for $2.50 and 3 bags of chips. the total cost was $5.05 write and solve an equation to determine

Wittaler [7]

First, write it as an equation

2.50+3x=5.05

Next, subtract 2.50 from both sides

2.50-2.50+3x=5.05-2.50

3x=2.55

Divide 3 on both sides

3x/3=2.55/3

x=0.85

The cost of a bag of chips is 0.85

hope i helped :D

What are the y-intercept of the function f(x)=-2x^2-3x+20?

Serhud [2]

Answer:

$\sf A) \ (-4, \ 0) \ and \ \ [\dfrac{5}{2} , \ 0]$

Explanation:

Given function: f(x) = -2x² - 3x + 20

To find the x-intercepts of a function, f(x) = 0

=================

-2x² - 3x + 20 = f(x)

-2x² - 3x + 20 = 0

-2x² - 8x + 5x + 20 = 0

-2x(x + 4) + 5(x + 4) = 0

(-2x + 5) (x + 4) = 0

-2x + 5 = 0, x + 4 = 0

-2x = -5, x = -4

x = -5/-2,x = -4

x = 5/2, x= -4

Coordinates: (-4, 0), (5/2, 0)
