Answer: (C) shifts 6 units to the LEFT

<u>Step-by-step explanation:</u>

The vertex form of an absolute value equation is:

y = a |x - h| + k where;

a is the vertical stretch (irrelevant for this problem)
(h, k) is the vertex

Since h represents the x-coordinate and the x-axis is left to right, then h shifts the graph left or right.

If h is negative, the graph shifts to the left.
If h is positive, the graph shifts to the right.

x + 6 is actually x - (-6), so h is negative and the graph shifts to the left.

How do you multiply hundreds by tens?

coldgirl [10]

Answer:

to multiply any number by 10, just tag ONE zero on the end. To multiply any number by 100, just tag TWO zeros on the end. To multiply any number by 1,000, just tag THREE zeros on the end. Note especially what happens when the number you multiply already ends in a zero or zeros.

What is value of x<br> Enter your answer in the box.

borishaifa [10]

Answer:

x=10

Step-by-step explanation:

Lets use a ratio.

3:2 (12 to 8)

We need to scale the x+4 up 3/2 to be equal to 2x+1

(3/2) x+4 = 2x+1

1.5x+6=2x+1

-1.5x -1.5x

6=0.5x+1

-1 -1

0.5x=5

x=10

2. The number of atoms of a particular chemical element is modelled by

____ [38]

9514 1404 393

Answer:

a) 600

b) see below

c) 1.26 hours

Step-by-step explanation:

a) The value of y when x=0 is the coefficient of the exponential term:

y = 600·3^(-0) = 600·1 = 600

There were 600 atoms to start.

b) see attached for a graph

c) The graph shows 150 atoms at t = 1.26, about 1.26 hours after the start of time counting.

If you want to find that value algebraically, substitute for y and solve for x. Logarithms are involved.

150 = 600·3^(-x)

150/600 = 3^(-x)

log(1/4) = -x·log(3)

x = -log(1/4)/log(3) = log(4)/log(3) ≈ 1.2618595

After about 1.26 hours, there were 150 atoms.

A new novel is selling for $17.95. If it is on sale at 40% off, find the amount of discount and the sale price.

nadya68 [22]

Answer:

Step-by-step explanation:

multiply $17.95 by 40% to get the discount ($17.95 x .4), which equals $7.18.

the sale price is the initial price of the book less the discount ($17.95-$7.18), which equals $10.77.
