Answer:
Look below.
Step-by-step explanation:
The following shape is being reflected across the y-axis.
To confirm this, we can check the coordinates.
When something is reflected across the y-axis, its points' y-coordinate don't change. Upon evaluation of the given transformation, we can see that the y-coordinate does not change for any point.
Now, we check the x-coordinate. The x-coordinate MUST be the opposite of the original x-coordinate...
-2 --> 2
-4 --> 4
0 --> 0
-4 --> 4
-2 --> 2
All of the x-coordinates are opposites, and the y-coordinates remained the same, therefore this figure is being reflected across the y-axis.

What is the area, in square units, of triangle RST?
Answer:
Step-by-step explanation:
The area of the larger rectangle is (4)(5)=20.
The area of the top left right triangle is (1/2)(2)(5)=5.
The area of the top right right triangle is (1/2)(2)(1)=1.
The area of the bottom right triangle is (1/2)(4)(4)=8.
So A = 20 - 5 - 1 - 8 = 15 - 9 = 6.

Answer:
1.) 163
2.) 56
3.) 94
Step-by-step explanation
Because the angles are supplementary, it means they equal 180 degrees. Therefore, just use this equation to found the unknown angle.
180-(The Number you are given) = (The angle you want)
For Example,
180-86=94

A rectangle has an area of (x2 − 17x + 72) square units. Since the area of a rectangle is determined using the formula, A = lw, what could be the length and width of the rectangle?
length = (x − 8) units and width = (x − 9) units
length = (x + 9) units and width = (x + 8) units
length = (x − 6) units and width = (x − 12) units
length = (x + 12) units and width = (x + 6) units
Answer:
The results are the opposite sign of x1 and x2.
[tex]lenght \: = (x - 8) \: and \: width \: = (x - 9)[/tex]
Step-by-step explanation:
[tex] {x}^{2} - 17x + 72 = 0[/tex]
[tex]Δ = {(17)}^{2} - 4(1 \times 72)[/tex]
[tex]Δ = 289 - 288 = 1[/tex]
[tex]x1 \: and \: x2 = \frac{17± \sqrt{1}}{2} [/tex]
[tex]x1 = \frac{17 + 1}{2} = 9[/tex]
[tex]x2 = \frac{17 - 1}{2} = 8[/tex]

Part (a)
x = number of adults
y = number of students
5x = amount all of the adults paid ($5 each)
2y = amount the students paid ($2 each)
5x+2y = total amount of money for adults and students combined
The total amount (5x+2y) must be more than $150
So we end up with 5x+2y > 150 as the inequality.
This inequality involves the boundary line 5x+2y = 150 which goes through the y and x intercepts of (0,75) and (30,0) respectively. We use a dashed line for the boundary to mean that points on the boundary are not included as solution points.
We shade above the dashed boundary line to finish off the graph.
Refer to figure (a) shown below.
========================================================
Part (b)
x = number of adults
y = number of students
x+y = total number of people
120 seats is the max capacity so x+y cannot exceed this value.
x+y = 120 or x+y < 120
Or in short x+y ≤ 120 is the inequality
This involves the boundary line x+y = 120 which goes through the y and x intercepts of (0,120) and (120,0). We shade below the solid boundary line.
Refer to figure (b) shown below.
========================================================
Part (c)
Now imagine we overlapped the blue region from part (a) and the red region from part (b)
We'll get the purple region shown in figure (c). At this point, I'm only considering cases when x ≥ 0 and when y ≥ 0. It's not possible to have a negative number of people, so that's why we focus on the upper right quadrant of the xy grid.
This purple region consists of all (x,y) points that make ALL of the inequalities to be true. Exclude any points on the dashed boundary.
For example, if we picked the point (x,y) = (50,40) then this point is in the purple region. We can confirm its a solution by checking each inequality.
5x+2y > 150
5*50+2*40 > 150
250+80 > 150
330 > 150 .... which is true
and,
x+y ≤ 120
50+40 ≤ 120
90 ≤ 120 ... which is also true
Furthermore, both x and y are nonnegative making x ≥ 0 and y ≥ 0 to be true as well. Every inequality mentioned is true for (x,y) = (50,40) to fully confirm the solution point. There are other possible solutions such as (40,60) and (80,20) which I'll let you verify.
If we stick to the (50,40) from earlier, then this means 50 adults and 40 students went to the concert.
Answer: 50 adults and 40 studentsOther answers are possible

Answer:
LM = 22
Step-by-step explanation:
11(44) = (LM)^2
484 = (LM)^2
LM = √484 = 22
Answer:
LM = 22
Step-by-step explanation:
If a tangent segment and a secant segment are drawn from an exterior point to a circle, then the square of the measure of the tangent segment is equal to the product of the measures of the external secant segment and the secant segment.
So for this circle,
point of intersection = Mtangent segment = LMexternal secant segment = NMsecant segment = OMSo LM² = NM · OM
Given:
NM = 11OM = 44LM² = 11 · 44 = 484
⇒ LM = √484 = 22
find the standard form, center, and radius of the following circles
1. x2+y2-4x+8y-5=0
2. 4x2+ 4y2+36y+5=0
Answer: The standard form a circle is (x−h)2+(y−k)2=r2 , where (h,k) is the center of the circle and r is the radius of the circle. Therefore, the center of the circle is at (2,4) and the circle has a radius of 5 .

Please Help Me Complete My Assignment I'm On Question 9
Answer:
B
Step-by-step explanation:
Simply choose an x coordinate and plug it into the equations from the choices given.
i.e. where x=1
y=2(1)^2 - 4(1)
y= 2-4
y= -2
it can then be seen that where x=1 on the graph, y= -2 aligns perfectly
Answer:
B
Step-by-step explanation:
In y = 2x^2-4x, we put y = 0 to represent the intersection points on the x-axis of the graph. (Since y = 0 is always on the x-axis)
For 2x^2-4x = 0, using the quadratic formula, we get x = 0 and x = 2.
This matches the int. points on the graph.
f(x) = (x + 2)²
f(5) = ?
»f(x) = (x + 2)²
»f(5) = (5 + 2)²
»f(5) = 7²
»f(5) = 49✅
~Hello! I will try to help you!
•Given : -
f(x) = (x + 2)² f(x) = (x + 2)(x + 2) f(x) = x² + 4x + 4•To Find : -
f(5) = ?•Step-by-step explanation : -
[tex] \Rightarrow \sf f(x) = {x}^{2} + 4x + 4[/tex]
»Just substitute the value 5 into the function f(x) above, then:-
[tex] \Rightarrow \sf f(5) = {5}^{2} + 4(5) + 4 \\ \Rightarrow \sf f(5) = 25 + 20 + 4 \\ \Rightarrow \sf f(5) = \bf49[/tex]

Pulling out like terms
3.1 Pull out like factors :
8g2 - 10g - 12 = 2 • (4g2 - 5g - 6)
Trying to factor by splitting the middle term
3.2 Factoring 4g2 - 5g - 6
The first term is, 4g2 its coefficient is 4 .
The middle term is, -5g its coefficient is -5 .
The last term, "the constant", is -6
Step-1 : Multiply the coefficient of the first term by the constant 4 • -6 = -24
Step-2 : Find two factors of -24 whose sum equals the coefficient of the middle term, which is -5 .
-24 + 1 = -23
-12 + 2 = -10
-8 + 3 = -5 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -8 and 3
4g2 - 8g + 3g - 6
Step-4 : Add up the first 2 terms, pulling out like factors :
4g • (g-2)
Add up the last 2 terms, pulling out common factors :
3 • (g-2)
Step-5 : Add up the four terms of step 4 :
(4g+3) • (g-2)
Which is the desired factorization
Final result :

Amanda wants to buy a new iPod that costs $250. When she gets to the Apple store
she sees they are having a sale for 15% off all iPods. She also has a coupon that takes
an additional 15% off the discounted price. What is the final cost of the iPod? (multi
step problem) (first you need to find the price when you take 15% off, and then you
take an additional 15% off of the discounted price)
Answer:
Answer:
