Consider the functions:
f(x) = (two-thirds) Superscript x
g(x) = (two-thirds) Superscript x minus 3 + 2
Which statement is true regarding the vertical and horizontal translations from f(x) to g(x)?
The function f(x) was translated left 3 units and up 2 units.
The function f(x) was translated right 3 units and down 2 units.
The function f(x) was translated left 3 units and down 2 units.
The function f(x) was translated right 3 units and up 2 units.
Answer:
The function f(x) was translated right 3 units and up 2 units.
Step-by-step explanation:
F(x)=(2/3)^x
If we move it right for 3 units, we get
f(x)= (2/3)^(x-3)
If we move up 2 units , we get
g(x)= (2/3)^(x-3) +2

In ten-pin bowling, the highest possible score in a single game is 300. At one point in the bowling season, Fred F Stone had an average score of 177. In his next game he obtained a score of 199, which caused his average to increase to. 178. After one more game Fred would like his average to be 183. Is it possible for Fred
Let, number of games played is n and sum of their points are x.
So, [tex]177=\dfrac{x}{n}[/tex]
Now, In his next game he obtained a score of 199, which caused his average to increase to 178.
[tex]178=\dfrac{x+199}{n+1}[/tex]
Now equations are :
x = 177n ...1)
x + 199 = 178( n + 1 )
x = 178n - 21 ...2)
Solving eq 1 and 2 , we get :
x = 3717 and n = 21 .
Now, new average is 183.
Let, point scored in last game is y.
So,
[tex]183 =\dfrac{x+y}{n+1+1}\\\\183 = \dfrac{3717+y}{23}\\\\y = 183\times 23 - 3717\\\\y=492[/tex]
He required 492 points which is greater than the maximum i.e 300.
Therefore, it is not possible for Fred.
Hence, this is the required solution.

What is the slope of 12x + 3y =7
Answer: y = -4x + 7/3 so the slope is -4
Step-by-step explanation:
First, we need to put the linear equation into the slope-intercept form: y = mx + b
We do this by subtracting 12x from both sides, so the equation now looks like 3y = -12x + 7. Now we divide both sides by 3 to get y alone, which gives us y = -4x + 7/3
m is always the slope, so the slope of this line is -4 or -4/1.

A roll of chain is 26 000 mm long to 2 sf. Necklaces are 540mm exactly. What is the greatest guaranteed number of necklaces that could possibly be made from the roll?
Answer:
47
Step-by-step explanation:
2 sf for this number means to the nearest 1 000
1 000 ÷ 2 = 500
So length of chain on roll is 26 000 ± 500
Greatest guaranteed number given by 25 500 ÷ 540 = 47.33... so answer is 47.

George is helping the manager of the local produce market expand her business by distributing flyers
around the neighborhood. He gets paid $20 a day as well as $0.05 for every flyer he distributes.
George would like to earn at least $65 each day. Which of the following represents this situation,
where x is the number of flyers distributed.
a. 20 + 0.05x ≤ 65 c. 20 + 0.05x ≥ 65 c. 20 + 0.05x ≥ 65
b. 20 + 5x ≤ 65 d. 20 + 5x ≥ 65 d. 20 + 5x ≥ 65
Answer:
20 + 0.05x ≥ 65
Step-by-step explanation:
20 is by itself since thats what he earns extra per day.
Since he earns 0.05 per flyer, that means we are going to need a variable since we don't know how many flyers he passes. Let x be equal to that.
Since he wants to make at LEAST 65 we are going to use the greater than or equal to symbol since he doesn't want to make less than that.
20 + 0.05x ≥ 65
Best of Luck!

9514 1404 393
Answer:
see below
Step-by-step explanation:
When a figure is rotated about a center point, the central angle formed by any point on the figure and the corresponding image point will be the rotation angle. Every image point is the same distance from the center of rotation that the pre-image point was. No lengths or angles are changed: rotation is a "rigid motion", so the rotated figure is congruent with the original.
__
-Angle AQA' is 60 degrees.
-Triangles ABC and A'B'C' are congruent.
-Angle ABC is congruent to angle A'B'C'. (this is one of the angles of the congruent triangles)
-Segment BC is congruent to segment B'C'
-Segment AQ is congruent to segment A'Q.

System of equations?
Answer:
Good day sir
The answer is (3,7)
Step-by-step explanation:
One way is to graph the line
Another way is to do it the hard way
3x + y = 16 is y = -3x + 16
Add the original equations up and solve
2y = -x + 17
This is a start (just solve this equation) but the answer is (3,7)

A perfect square is a number that can be expressed as the product of an integer by itself , 169,196,225 are the perfect squares that are greater than 150 and less than 250.
What is perfect square?A perfect square is a number that can be expressed as the product of an integer by itself or as the second exponent of an integer
greater than 150 and less than 250 perfect squares we need to find.
According to the definition of perfect square
if we multiply 13*13 we get 169 which is in between 150 and 250
if we multiply 14*14 we get 196 which is in between 150 and 250
if we multiply 15*15 we get 225 which is in between 150 and 250
