Find the inverse of the equation y=x2+3

Answer:

-1

f (x) = sqrt(x - 3)

Step-by-step explanation:

Hope you won't mind the correction, but that's y = x^2 + 3. Use " ^ " to indicate exponentiation.

Starting with y = x^2 + 3, interchange x and y:

x = y^2 + 3

Next, solve for y: y^2 = x - 3, or y = +sqrt(x - 3).

Note that we'd normally write "plus or minus sqrt(x - 3)," but that would provide two y values for each x value (which violates the definition of "function').

Finally, replace "y" with the inverse function label:

-1

f (x) = sqrt(x - 3)

The answer to your question is 100 degrees. To find the sum of an exterior angle, you add the too opposing interior angles. So 50 and 50 is 100. May I have branliest plz? I need one more to be an expert.

You have $30 to buy muffins. However, at the shop you can buy 1 muffin for $4. (a) Write an inequality from the above informatio

sattari [20]

Answer:

Let m be the number of muffins.

a) 4m <= 30

b) m <= 7.5, so the maximum number of muffins to buy is 7.

c) $4 × 7 = $28, so $2 will be left over.

Write the number 5267 correct to<br> the nearest hundred.

galben [10]

Answer:

5300.

If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.

dlinn [17]

Answer:

See below

Step-by-step explanation:

The ratio of the secants is the same when set up as full length to external length.

Formula

MN/LN = QN/PN

Givens

LN = 22 + 14 = 36

MN = 14

PN = 32

QN = x

Solution

14/36 = x / (32) Multiply both sides by 32

14*32 / 36 = x Combine 14 and 32

448/36 = x Divide by 36 and switch

x = 12.4

Answers

PN (External) = 13 is the closest answer

Length LN = 36

Find the midsegment of the triangle which is parallel to CA.

Nataliya [291]

Answer:

$\pmb{ \pink{QUESTION�}}$

Find the midsegment of the triangle which is parallel to CA.

$\pmb{ \pink{ANSWER:-}}$

Tip

A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle.
This segment has two special properties. It is always parallel to the third side, and the length of the midsegment is half the length of the third side.
If two segments are congruent, then they have the same length or measure.In other words, congruent sides of a triangle have the same length.

$\frak{Explanation:-}$

We have to find the segment which is parallel to CA.

From the given data,

The segment EG is the midsegment of the triangle $\triangle$ ABC.

So we have,

A midsegment of a triangle is a segment connecting the midpoints of two sides of a triangle. This segment has two special properties. It is always parallel to the third side.

$\implies\rm{midsegment \: EG \: parallel \: to \: CA}$
