I believe the answer is B.

It says that he made 100 cupcakes so we know that the total is 100. It says he baked 4 more than so that means that we are adding 4 to some value. It also says that he baked 3 times the total of cupcakes he made last week. Since the total for last week is unknown, we can express that as x.

So, your equation would be 3x+4=100.

Hope this helps!

part 3. Find the coordinates of the vertices of the triangle after a reflection across the y-axis and then across the line y= 2.

garik1379 [7]

Answer:

c. S'(3, 1), T'(1, -1), U'(0, 1)

Step-by-step explanation:

Reflection across the y-axis negates the x-coordinate, so is equivalent to the transformation ...

(x, y) ⇒ (-x, y)

Reflection across the horizontal line y=c is equivalent to the transformation ...

(x, y) ⇒ (x, 2c-y)

So, the combined reflections are equivalent to the transformation ...

(x, y) ⇒ (-x, 4 -y)

Then we have ...

S(-3, 3) ⇒ S'(-(-3), 4-3) = S'(3, 1)

T(-1, 5) ⇒ T'(-(-1), 4-5) = T'(1, -1)

U(0, 3) ⇒ U'(-(0), 4-3) = U'(0, 1) . . . . matches choice C

Choose all that rearrange the formula correctly.If

Sonbull [250]

Answer:

I sure hope none is an answer because none of these work!

Step-by-step explanation:

C = 59 (F - 32)

(C/59) = F - 32

F = C/59 + 32

So no :(

m = x + y + z3

y = m - x - z3

So no :((

s = r^2 - 1

r = sqrt(s+1)

So no :000

A = 12(a+b)

A = 12a + 12b

12b = A - 12a

b = A/12 - a

So no :00(((

m = x + y^2

y = sqrt (m-x)

AND no :|

A square window has a perimeter of (8x+12) feet. Write an expression that represents the side length of the window (in feet). Pl

Perimeter of a square = 4L
4L = (8x+12)ft
L= (2x+3)ft
