5(x-3)-x =

Multiply Everything In The Parentheses By 5

5x-15-x

i) first you combine the like terms; 3x² and x², then 4x and -8x, then -7n and -1.

Then you would get 4x²-4x-8.

You then cannot simplify further. so your answer would be 4x²-4x-8.

**Answer:**

Phyllis will save $73 when buying the TV at store B.

**Step-by-step explanation:**

Store A is selling the TV at $498. Store B is selling the TV at $425. To find how much money he will save if he buy the TV at store B we need to find the difference:

$498 - $425 = $73

**Answer:**

y=2x+17

**Step-by-step explanation:**

Given the table values as;

x 0 1 3

y 5 7 11

Take values as coordinates in x,y format to have points

(0,5) , (1,7) and (3,11)

Find Δy which equals to the gradient using two points

Δy=7-5/1-0 = 2/1=2

m=2

Take the other point (3,11) and (x,y) to find the relationship in form of y=mx+c

y-11/x-3 = 2 --------------cross multiply

y-11=2(x-3)------------open the brackets

y-11=2x+6---------------collect like terms

y=2x+6+11

y=2x+17

If I could give you an answer, I would. But I'm terrible at Math so, sorry
