Answer:   \bold{\{-2, \dfrac{5}{2}\}}

<u>Step-by-step explanation:</u>

2x² - x - 10 = 0

Replace -x with 4x - 5x and factor using Grouping Method:

2x² + 4x  -5x - 10   = 0

2x<u>(x + 2)</u>  -5<u>(x + 2)</u> = 0

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

2x - 5 = 0   and    x + 2 = 0

2x = 5         and    x = -2

x = 5/2

Helpppppp pleaseeeeee !!!!!!!!! !!!!

Given:

The function is:

f(x)=6x-3

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

f(x)=6x-3

Step 1: Substitute f(x)=y.

y=6x-3

Step 2: Interchange x and y.

x=6y-3

Step 3: Isolate variable y.

x+3=6y

\dfrac{x+3}{6}=y

Step 4: Substitute y=g(x).

\dfrac{x+3}{6}=g(x)

Therefore, the inverse of the given function is g(x)=\dfrac{x+3}{6} and the graphs of these functions are shown below.

Someone pls do these 3 for me, its due in 20 minutes and my head hurts so bad right now :(

Answer:

1. Chloe has more money.

2. Dylan does <u>not</u> have enough money to buy 3 bags of candy.

3. Mikayla could get 4 pennies, 2 nickels, 2 dimes, and 2 quarters back in change.

Step-by-step explanation:

Penny = 1 cent

Nickel = 5 cents

Dime = 10 cents

Quarter = 25 cents

1. Chloe has 2 quarters(50 cents) and 3 dimes(30 cents). 50 + 30 = 80 cents

Haru has 5 nickels(25 cents) and 4 dimes(40 cents). 25 + 40 = 65 cents

2. If each bag costs $350(oddly enough). Dylan would need $1,050 to buy 3 bags of candy. Instead he only has $10. This means he would need $1,040 more dollars.

3. $5 - 4.16 = 84 cents in return

quarter(25) + quarter(25) + dime(10) + dime(10) + nickel(5) + nickel(5) + penny(1) + penny(1) + penny(1) + penny(1) = 84 cents
