Answer: f(x)=3x^2-17x+10 (in other words the bottom one)

Step-by-step explanation:

Answer:

last option is correct

f(x)=3x^2−17x+10

Step-by-step explanation:

3x^2−17x+10=0

using the Quadratic Formula where

a = 3, b = -17, and c = 10

x=−b±√b2−4a/2a

x=−(−17)±√(−17)2−4(3)(10)/2(3)

x=17±√289−120/6

x=17±√169/6

x=(17±13)/6

x=30/6 , x=4/6

Answer:

measure of angle YVZ=56°

Step-by-step explanation:

angle WVY and angle YVZ form a right angle, meaning they add to 90 degrees.

We can make an equation out of this:

2x+3x+5=90

solve for x

5x+5=90

5x=85

x=17

substitute x back into the expression for angle YVZ because that's the measure we're looking for

angle YVZ=3(17)+5=56

It’s 56 degrees, hope this helped!

This graph represents a proportional relationship between the number of months, x, data is used on a cell phone and the total cost of data usage, y.

The equation that represents the graph above is y =
x.

The cell phone company decides to raise the data prices to charge $90 every 2 months. The new equation that would represent this relationship is y =
x.

Answers

Answer:

1. y = 40x

2. y = 90x

Step-by-step explanation:

In the graph, for every one unit to the right, the graph increases by forty (up forty, over one). Since x is the unknown number of months, and it’s $40/month, y = 40x. After they raise the prices, it is $90 every month, so now it’s y = 90x. Hope this helps!

Answer:

1) y = 40x

2) y = 45x

x = months

Step-by-step explanation:

1) 40/1 = 40

2) 90/2 = 45
