Which equation is the inverse of y = 100 – x2?

sdas [7]

Answer:

Step-by-step explanation:

$\tt\displaystyle y = 100 - x^2\to\{y = x\}\\\\x = 100 - y^2\to\\\\y^2 = 100 - x\to\\\\y = \pm\sqrt{100 - x}$

Solve the following system of linear equations. 3x + 2y = 10 2x + 3y = 15/2 No solution y = (-3/2)x + 5 x = 3, y = -1/2 x = 3, y

frutty [35]

3x + 2y = 10 .....multiply by -2
2x + 3y = 15/2...multiply by 3
------------------
-6x - 4y = -20 (result of multiplying by -2)
6x + 9y = 22.5 (result of multiplying by 3)
-----------------add
5y = 2.5
y = 2.5/5
y = 1/2

3x + 2y = 10
3x + 2(1/2) = 10
3x + 1 = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3

solution is (3,-1/2)

Help i don't understand this

ss7ja [257]

Answer:

yes it is possible to get a common denominator grater than 12 and still get the right answer.

Step-by-step explanation:

This is because the numerator is always directly corelated to de denominator therefore the fraction wouldn't change because when simplified it is the same fraction as it would be with 12 as the denominator

If a circle has a radius length of 2x units, what is the circle's circumference?

Brut [27]

Answer: 12.56

Step-by-step explanation:

If I remember correctly, the equation for circumference is C=2r*pi (R representing radius). For this problem, if 2 is your radius 2R would equal 4. Take this number and multiply it by 3.14 (pi) to get your final answer.

Big ideas math 1.2 Practice A number 19

By applying Segment Addition Postulate, segment FH is equal to 24 units.

<h3>What is a point?</h3>

A point can be defined as a zero dimensional geometric object and it is generally represented by a dot.

<h3>What is a line segment?</h3>

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

<u>Given the following data:</u>

Line segment FG = 37.

Segment HG = 13.

Since point H lies on line segment FG, we would apply Segment Addition Postulate to determine segment FH as follows:

FG = HG + FH

37 = 13 + FH

FH = 37 - 13

FH = 24 units.

Complete Question:

Given that line segment FG = 37 and segment HG = 13, find segment FH.
