What set of reflections would carry triangle ABC onto itself?

Answers

The correct answer is y-axis, x-axis, y-axis, x-axis. The y-axis is the vertical line, and the x-axis is the horizontal line. If the triangle is in the upper right quadrant, and is reflected first over the y-axis, it will be in the upper left quadrant. Then, when the triangle is reflected again over the x-axis, it will be in the lower left quadrant, diagonal to the initial triangle. When the triangle is again reflected over the y-axis, it will be in the lower right quadrant, below the initial triangle. Finally, when the triangle is reflected over the x-axis, it will be on top of the original triangle in the upper right quadrant.

Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1).

The value of f(-1) is -6

what is function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Given:

f(x) = 12/ (4x +2)

for x=-1

then,

f(-1) = 12/ ( 4(-1) + 2)

f(-1) = 12/ (-4 + 2)

f(-1) = 12/(-2)

f(-1) = -12/2

f(-1) = -6

Hence, the value of f(-1) is -6

f(x)= 12 / (4x+2 )
f(-1) mean to replace x by (-1)
so, f(-1) = 12 /(-4+2)
f(-1)= 12/-2
f(-1) = -6

225 grams of flour are needed to make 9 cakes.Marian wants to make 20 of these cakes.
She has 475 grams of flour.
Does Marian have enough flour to make 20 cakes?

Answers

So basically, 9 cakes need 225 grams of flour
Therefore 1 cake needs: $(225)/(9)$ = 25 grams of flour

Moreover, 20 cakes need: 20 × 25 = 500 grams of flour

500 g > 475 g

Marian does not have enough flour to make 20 cakes
