Yes or No
1. y = x2 + 3
2. y = 4x - 5
3.y=18 – 34²
4. y = 3* + 3
5. y = 4x2 + x + 4
6. y = 3 + 4x + 2
7. y=34²
8. y = (x - 1)(x + 9)
9. (x-2)(x + 2) + x2 - y = 0
10. 0 = y + 5x3 - 3x

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
