If f(x) = 2x + 1 and g(x) = -(x - 1)² + 3 what is the smallest solution for f(x)=g(x)?

Sauron [17]3 years ago

Answer:

<em>The smallest solution is x=-1</em>

Step-by-step explanation:

<em>Quadratic Equation</em>

We have:

f(x)=2x+1

g(x)=-(x-1)^2+3

We'll find the solutions of f(x)=g(x), or:

2x+1=-(x-1)^2+3

Operating:

2x+1=-(x^2-2x+1)+3

2x+1=-x^2+2x-1+3

Rearranging all terms on the left side:

2x+1+x^2-2x+1-3=0

Simplifying:

x^2-1=0

Since the term with the x is missing, we can solve for x:

x^2=1\qquad\Rightarrow x=\sqrt{1}=\pm 1

There are two solutions:

x=1, x=-1

The smallest solution is x=-1

Help me I need help I need help
Licemer1 [7]

Answer:

\Huge\boxed{131.88}

Step-by-step explanation:

Hello There!

First thing we want to do is find the formula for circumference of a circle

C = 2(3.14)r

where r = radius

we are given the diameter so we have to convert that into radius to do so we just divide by 2

42/2=21 so the radius equals 21 inches

now we just plug in 21 for r in the formula

C = 2(3.14)21\\2*3.14=6.28\\6.28*21=131.88\\C=131.88

So we can conclude that the circumference of the circle is 131.88 inches

Factor by using the difference of two cubes
Nikolay [14]

Answer:

Step-by-step explanation:

a) a^3-64b^3

=(a)^3-(4b)^3

=(a-4b)(a^2+4ab+16b^2)

b) 3x^3-81y^3z^6

=3(x^3-27y^3z^6)

=3{(x)^3-(3yz^2)^3}

=3(x-3yz^2)(x^2+3xyz^2+9y^2z^4)

c)16a^3b^3-54c^3d^3

=2(8a^3b^3-27c^3d^3)

=2{(2ab)^3-(3cd)^3

=2(2ab-3cd)(4a^2b^2+6abcd+9c^2d^2)

hope u got!!

1. Mark each of the following graphs as (a) a function, but not one-to-one, (b) one-to-one function, or (c) not a function. In e
Helen [10]

Answer:

  (a) a function, but not one-to-one

Step-by-step explanation:

The graph is of a function if it passes the vertical line test: a vertical line intersects the graph in at most 1 point.

The function is one-to-one if it passes the horizontal line test: a horizontal line intersects the graph in at most 1 point.

__

Here, the graph consists of a series of non-overlapping horizontal lines. It passes the vertical line test (is a function), but a horizontal line can intersect the graph in an infinite number of points (is not one-to-one).

The graph is a function, but not one-to-one.
