Answer:
y= Ix-3I (that says absolute value btw)
Step-by-step explanation:
This is the result of starting with y = |x|, then shifting it three units to the right. Replacing x with x-3 moves the xy axis three units to the left, giving the illusion the V shaped curve moved 3 spots to the right.
We don't shift up or down since the vertex is on the x axis.
We also don't vertically compress or stretch the graph either.
Side note: the vertex for this graph is (3,0) which is the lowest point of the curve.

One side of a triangle is twice as long as a second side. The remaining side is 3 larger than the second side. The perimeter is 39m. Find the length of each side.
Answer:
Lengths all the three sides are 9m, 18m and 12m
Step-by-step explanation:
Let us assume the length of the second side to be x m
According to the question:
first side = 2x
third side = x + 3
Applying the formula of perimeter:
Perimeter = length + breadth + height
39 = 2x + x + (x + 3)
39 = 2x + x + x + 3
39 = 4x + 3
39 - 3 = 4x
4x = 36
x = [tex]\frac{36}{4}[/tex]
x = 9
length of the first side (x) = 9 m
length of the second side (2x) =2 × 9 =18 m
length of the third side (x + 3) = 9 + 3 = 12 m
∴ lengths all the three sides are 9m, 18m and 12m

Drake needs to drill holes in a wooden plank. The holes will have a diameter of 0.5 millimeters, with an error allowance of 0.05 millimeters. Which equation can be used to find the minimum and maximum acceptable diameters?
Answer:
|x − 0.5| = 0.05
Step-by-step explanation:
Here x represents the diameter,
Since, an error of 0.05 millimeters is allowance in diameter,
Thus, the maximum acceptable diameter = x + 0.05,
And, the minimum acceptable diameter = x - 0.05
According to the question,
The holes will have a diameter of 0.5 millimeters,
Thus, x - 0.05 < 0.5 and 0.5 < x + 0.05
⇒ x - 0.5 < 0.05 and x - 0.5 > - 0.05
⇒ x - 0.5 < 0.05 and -(x -0.5) < 0.05
⇒ |x-0.5| < 0.05
⇒ Option D is correct.

Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Answer:
211 months
Step-by-step explanation:
Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Let the number of months that he prepays for be represented by m
Hence, we have the equation
$20 + $15 × m = $3185
Hence:
20 + 15m = 3185
Collect like terms
15m = 3185 - 20
15m = 3165
m = 3165/15
m = 211 months
Trey takes the angle shown, places the point of his compass on S, and draws an arc with an arbitrary radius intersecting the rays of the angle at P and R. Trey claims that as long as he draws two more arcs by placing the needle of his compass on P and then on R, drawing a ray from S through the point at which the arcs intersect, he will be able to bisect ∠S. Is Trey correct?
A. Trey is correct. Since the initial arc was drawn with the point of the compass on S, RS=PS.
B. Trey is not necessarily correct. He will need to ensure that the compass width remains the same for each arc drawn from P and R.
C. Trey is correct. Since the compass is placed on the points P and R to draw the remaining two arcs, the ray drawn through their intersection will bisect the angle.
D. Trey is not necessarily correct. He will need to ensure that the distance from S to P and the distance from S to R are equal.
Answer:
b
because he isnt fight nor wrong

A group of 5 friends want to buy a flat-screen TV for $210. The tax comes to $15. Write and solve a multiplication equation to find how much money each person should pay if each person pays the same amount.
Answer:
$45
Step-by-step explanation:
In order to create a multiplication equation, we would need to use a single variable that represents the amount that each friend will pay. This can be represented by the variable x. We multiply this variable by the number of friends which should equal the total of the TV with the tax included. Like so...
$210 + $15 = 5x
Now that we have the equation we can go ahead and solve it by adding the total and the tax, and then dividing both sides by 5 in order to isolate x.
$210 + $15 = 5x
$225 = 5x
$45 = x
Finally, we can see that each friend will pay the same amount which is $45
Michelle ordered shirts to sell at the school carnival. She paid $2.80 per shirt, she adds a
150% markup to the total price she paid for the shirts.
What is the selling price of each shirt?
PLEASE HELP!! Any help will be greatly appreciated!
Answer:
The selling price is $7
Step-by-step explanation:
Step one:
Given information
She paid $2.80 per shirt
She adds a 150% markup to the total price she paid for the shirts
Let us find 150% of $2.80
=150/100*2.8
=1.5*2.8
=$4.2
Hence the selling price is the markup price plus the cost price
=4.2+2.8
=$7

Kamal got married 5 years ago. Today his age is 1 1/4 times his age at the time of marriage. His sons age is 1/10 times his present age. What is hisson's age ?
Answer:Son's age =2.5 years old
Step-by-step explanation:
Step 1
Let the age of Kamla at marriage be represented as x
Age after five years = x+5
Given that today his age is 1 1/4 times his age at marriage, Our equation to express his age at marriage will be
x+ 5= (5/4)x
Multiplying 4 by both sides gives
4(x+5) = (5/4 x 4 )x
4x+20 = 5x
20=5x-4x
x= 20 years at Marriage
Therefore his present age = 20+5= 25
Step 2
Son' s age = 1/10 times his present age
Son's age = 1/10 x 25= 2.5 years old

When graphing on the complex plane , which quadrant will the complex number 10 - 13i be found in ?
Answer:
The complex number would be in the 4th quadrant.
Step-by-step explanation:
We know that a complex number is a number that can be expressed in the form of a + bi,
where
'[tex]a[/tex]' and b are real numbers, and '[tex]i[/tex] represents the imaginary unitGiven the complex number
10 - 13i
Here,
Coefficient of the real part of the complex number = 10Coefficient of the imaginary part of complex number = -13As the coefficient of the imaginary part holds a negative sign, and the real part holds a positive sign.
Thus, the complex number would be in the 4th quadrant.
