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
