43.)
a. There is an s amount of shoes, because s is the total amount of shoes
b. x is the number of shoes, so x - 1/2 = s

44.)
2s + 7 = x

45.)
the variable s is the total amount of shoes Pete has and 8 don't fit him anymore (or got ruined) so he threw them away... x - 8

46.)
The expressions y + 4 and 1y + 4 are equivalent, because a variable always has a hidden (1) next to it like (1)y and any positive number multiplied by 1 always stays the same.

I hope i helped : )

ABC is reflected across x = 1 and y = -3. What are the coordinates of the reflection image of B after both reflections?A. (-7, -

Dima020 [189]

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is noticed that the coordinates of B are (-5,-7).

If ABC is reflected across x = 1, then

$(x,y)\rightarrow(1-(x-1),y)$

$(x,y)\rightarrow(2-x,y)$

$(-5,-7)\rightarrow(2+5,-7)$

$(-5,-7)\rightarrow(7,-7)$

If ABC is reflected across y =-3.

$(x,y)\rightarrow(x,-3-(y-(-3)))$

$(x,y)\rightarrow(x,-6-y)$

$(7,-7)\rightarrow(7,-6-(-7))$

$(7,-7)\rightarrow(7,1)$

Therefore option C is correct.

Kiran scored 223 fewer points in a computer game than Tyler. Kiran scored 409 points. Which equation would Kiran use to determin

LenKa [72]

Answer:

The equation is:

$409 = T - 223$

And the solution is:

$T = 632$

Step-by-step explanation:

Given

Represent Kiran with K and Tyler with T

Kiran score is represented as:

$K = 409$

Also, Kiran scored 223 less than Tyler.

This is represented as:

$K = T - 223$

Substitute 409 for K

$409 = T - 223$

Make T the subject

$T = 409 +223$

$T = 632$
