OK.  Relax, settle down, don't worry.

We're in luck here.  The shape hasn't been rotated, or swelled up
or shrunk.  It's still exactly the same size and shape, and in the same
position.  It's only been moved, from here to there.  All you really
have to do is look at one point, and figure out how that point moved,
and all the other points moved exactly the same ... same distance,
in the same direction.

When I looked at this, I worked with point-D.  But now I think
point-B may be a little easier to work with.

-- What's the 'x'-value (left/right) of point-B before it moves ?
    It's right on the y-axis, so its x-value is zero.

-- What's the 'x' value of point-B', after the move ?
    Look at the light light line that B' is on, follow it down,
    and you see that the x-value of point-B' is  6 .

-- The x-value of point-B moved from  x=0  to  x=6.
    If you look at just the x-value of any other point on the shape,
    you'll see that every point moved 6 units to the right.
    Every 'x'-value became 6 units bigger after the move.
       x --> x+6

===================
 
-- What's the 'y'-value (up/down) of point-B before it moves ?
    It's in the middle between the 2 and the 4, so its y-value is 3.

-- What's the 'y' value of point-B', after the move ?
    Look at the light light line that B' is sitting on, follow it left,
    and you see that the y-value of point-B' is  8 .

-- The y-value of point-B moved from  y=3  to  y=8.
    If you look at just the y-value of any other point on the shape,
    you'll see that every point moved 5 units UP.
    Every 'y'-value became 5 units bigger after the move.
       y --> y+5

Look for a choice that says what we found.
The second choice says it.

Factoring , <br> a² +4a - 5
givi [52]

the factors of the term a^2+4a-5 are (a-1)(a+5)

Step-by-step explanation:

We need to find factors of the term: a^2+4a-5

For finding factors:

We need to break the middle term such that their product is equal to product of first and last term and their sum is equal to middle term

Breaking the middle term and finding factors:

a^2+4a-5

=a^2+5a-a-5

=a(a+5)-1(a+5)

=(a-1)(a+5)

So, the factors of the term a^2+4a-5 are (a-1)(a+5)

What the slope and y intercept ? and how did you find it ?
EastWind [94]

Answer:

Slope: m=4

y-intercept: b=-1

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

The slope can be found with the following formula:

m=\frac{y_2-y_1}{x_2-x_1}

In this case you can say that:

y_2=-5\\y_1=11\\\\x_2=-1\\x_1=3

Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:

m=\frac{-5-11}{-1-3}\\\\m=\frac{-16}{-4}\\\\m=4

By definition, the line intersects the y-axis when the value of "x" is 0.

Notice in the table that when x=0, y=-1

Therefore, the y-intercept is:

b=-1

Before a basketball game a referee noticed that the ball seemed under inflated. She dropped it from 6 feet and measured the firs
deff fn [24]

Answer: a) H = h( 0.5 )^n

b) H = 1.125inches

Step-by-step explanation:

Let H = height of the ball

n = number of time the ball bounces

h = initial height.

The exponential function to model the height of the ball will be:

H = h( 1 - 0.5)^n

H = h( 0.5 )^n

It's minus because the height of the ball is decreasing.

h = 36 inches

n = 5

H = 36( 1 - 0.5 ) ^5

H = 36( 0.5 )^5

H = 36 × 0.03125

H = 1.125inches

Given the equation square root of 8x plus 1 = 5, solve for x and identify if it is an extraneous solution. x = one fourth, solut
Rainbow [258]

Answer:

x=3, solution is not extraneous

Step-by-step explanation:

we have

\sqrt{8x+1}=5

Solve for x

squared both sides

(\sqrt{8x+1})^2=5^2

8x+1=25\\8x=25-1\\8x=24\\x=3

<u><em>Verify</em></u>

For x=3

\sqrt{8(3)+1}=5

\sqrt{24+1}=5

\sqrt{25}=5

5=5 -----> is true

therefore

x=3, solution is not extraneous
