Answer:

S = 13 - x

T = (18 + x) / 2

Step-by-step explanation:

S = 18

T= 18

Sue gives away x, so subtract it from 18. But Tony gets x, so add it to 18 in his expression.

S = 18 - x

T= 18 + x

Sue eats 5 so subtract 5 from her expression. Tony eats half, so divide his expression by 2.

S = 18 - x - 5

T = 18 + x / 2

Simplify 18-5.

S = 13 - x

T = (18 + x) / 2

What is the factorization???
Sav [38]

we can see that

the above curve is parabola

so, firstly , we can find vertex

vertex is (4,0)

(h,k)=(4,0)

now, we can use vertex formula of parabola

y=(x-h)^2+k

we can plug h and k

and we get

y=(x-4)^2+0

so, we can factor it as

y=(x-4)(x-4)............Answer

Warmup/Reflection- necessary for attendance
Pepsi [2]

Answer:

x = 7

Step-by-step explanation:

-3 + 2x = 11

(group like terms)

2x = 11 + 3

2x = 14

(divide both sides by 2 to make x stand alone)

2x/2 = 14/2

x = 7
