If the graph of y=|x| is compressed vertically by a factor of 1/3, reflected about the x-axis and translated 3 unit(s) left and 5 unit(s) up, what is the equation of the new graph?
Answer:
Y= -1/3 |x+3| +5
Step-by-step explanation:
An absolute value will always make a V line.
In your particular problem it wants you to reflect it over the x axis, and to do this you simply need to place a negative.
A negative in the beginning of the problem is only there to say whether you flip your line or not, and this means you don't have to worry about it any more.
What it looks like so far: Y= -
Next it wants you to compress the line vertically by 1/3
A number that causes your line to compress is always less than one
A number that stretches your line would be 1 or more
This number is always placed right next to the left of the parenthesis or absolute value.
What it looks like so far: Y= - 1/3
Now we want the line to move left 3 units.
We are now inside of the absolute value because this is where we move the line left or right. This can get a little confusing, but once you get it then you don't forget it.
Inside the line.. a -# moves right and a +# moves left.
This number should be placed inside the absolute value and to the right of the x.
What it should look like: Y= - 1/3 |x + 3|
Now they want us to move the line up by 5 points.
To the outer right side of the absolute value is where we move things up or down.
To move a number up you need to place a + sign with however many places it wants you to move to the right of the sign, but to move the line down you need to place a - sign with however many places it wants you to move to the right of the sign.
To move this up you simply need to place a +5 to the outer right side of the absolute value.
What you should end up with: Y= - 1/3 |x+3| +5

Answer 145°
Step-by-step explanation:
( 5x+5 ) + 40° = 15x - 5
[ Reason : exterior extended angle of a triangle is always equal to the sum of two non adjacent interior angles ]
( 5x+5 ) + 40° = 15x - 5
i.e, x= 10°
put this value of x on <PGF
= 15x - 5
= 15 * 10 - 5
=145°

Evaluate each value expression for the given value of x: 2x+10, x=7
Answer: 24
Step-by-step explanation: Here, we have the expression 2x + 10,
and we want to evaluate the expression when x = 7.
To an evaluate an expression, we simply plug
the value of the variable into the expression, and solve.
So here, since x = 7, we have 2(7) + 10.
2(7) is equal to 14 so we have 14 + 10 which is equal to 24.
So the value of our expression when x = 7 is 24.

What is zero of a function?Zero of a function is defined as the roots of the function for which the value of the function will be 0 at those points.
If p is the zero of the function f(x)=0 then f(p)=0.
We have,
f(x) = (x-1)² (x+3)³ (x+1)
Now,
The zero is located at x=1 and has a multiplicity of 2.
Because the number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity.
The zero is located at x = - 3 and has a multiplicity of 3. The graph of the function will touch, but not cross, the x-axis at the x - the value of 1.
The complete question is given below:-
Consider polynomial function f f(x)=(x-1)^2(x+3)^3(x+1)
use the equation to complete each statement about this function
The zero located and x=1 has a multiplicity of __ and the zero located at x=-3 has a multiplicity of __. The graph of the function will touch, but not cross, the x-axis at the x-value of __.

What is the slope intercept equation for thus line?
Answer:
y= 2/3 x + 4
y- intercept= (0,4)
and slope of the line is 2/3
Answer:
B.
Step-by-step explanation:
y = mx + b
The y-intercept is the point (0, 4), so you get b = 4
You now have
y = mx + 4
Now start at the y-intercept, (0, 4). Go up 2 units and right 3 units to a point on the line; rise = 2; run = 2.
slope = m = rise/run = 2/3
Now you have
y = 2/3 x + 4

Which two changes are caused by shear acting on Earth's crust?
Answer:

one slab of rock breaks into two peices
Step-by-step explanation:
The two changes caused by the shear on the earth crust are; A: One slab of rock breaks into two peices. C: Two slabs of rock slide past one another;
How to describe the shear acting on Earth's Crust?
Shear stress usually occurs when two plates rub against each other as they move in opposite directions.
Now, when shear stress occurs on the earth's crust, the force generated by the stress tends to push some of the crust in different directions. This would mean that a large part of the crust can break off, which makes the plate size smaller.
Thus, when a shear stress acts on the earths' crust, One slab of rock breaks into two peices. C: Two slabs of rock slide past one another;

1.Mario purchased 15 tickets to a football game for $13.50. How much would it cost to purchase 21 tickets? $ ____________
2.Student Council sells bottled water at the cheerleading competition as shown below. Determine of each statement is true or false.
Cases sold: 3 6
Time (min): 20 40
a) They sell 27 cases in 3 hours
b) They sell 12 cases in 1 hr 20 minutes
c) They sell 18 cases in 2 hours
d) They sell 24 cases in 2 hrs 40 minutes
e) They sell 36 cases in 3 hrs 20 minutes
Answer:
1. $18.90
2. Every statement is true EXCEPT e
Step-by-step explanation:
For number 1. We first need to find how much one ticket costs. To find this we divide profit by number of tickets sold. So,
13.50/15 = $0.90
So to find the cost of 21 tickets we times the cost per ticket by 21
21 x 0.90 = 18.9
So $18.90
2.
They sold 6 cases in 40 minutes.
6/40 = 0.15
They sell 0.15 cases per minute
For a we wanna see if they can sell 27 cases in 180 minutes so
0.15 x 180 = 27
So a is true
B)
0.15 x 80 = 12
So b is true
C)
0.15 x 120 = 18
C is true
D)
0.15 x 160 = 24
D is true
E)
0.15 x 200 = 30
E is false

X = _____ ??
m < ABC _____ ??
m < CBD _____ ??
Please help! I’ll give brainliest!!
Step-by-step explanation:
2x+13x-15=180 since a linear pair is a pair of consecutive angles that adds up to 180 degrees.
15x-15=180 because we combine like terms.
15x=165 because of the subtraction property of equality.
x=11 by the division property of equality.
abc=22 by substitution and multiplication
cbd=143-15 by substitution and multiplication
cde=128 by subtraction

Given that AD is the perpendicular bisector of BC, AB=21.3, AC=21.3, and DC=9.1, identify BC.
a) BC = 42.6
b) BC = 18.2
c) BC = 9.1
d) BC = 4.55
sorry i can't upload a picture of the triangle but this is from an luoa assignment. i know it's not C
answer. B hope this helps
The length of BC is 18.2 units.
The correct answer is option b) BC = 18.2.
Since AD is the perpendicular bisector of BC, it divides BC into two equal segments. Let's call the point of intersection between AD and BC as M. Therefore, BM = MC.
According to the given information,
AB = AC = 21.3. Since AD is the perpendicular bisector of BC, it implies that AM is equal to MC.
Therefore, AM = MC = BC/2.
We are also given that DC = 9.1. Since MC = DC, we can conclude that BC/2 = 9.1.
To find BC, we can multiply both sides of the equation by 2:
BC = 2 x 9.1
BC = 18.2.
