Answer:
Vertex (2, 3)
Axis of Symmetry: x = 2
Step-by-step explanation:
You can look at the labeling from my last answer, the parabola is just upside down but it is still the same label.
Hope it makes sense :)
Answer:
Axis of Symmetry: x = 2
Vertex: (2, 3)
Step-by-step explanation:
find axis of symmetry: x = -b/2a
x = -8 ÷ 2(-2)
x = 2
find vertex by substituting 2 for 'x':
y = -2(2²) + 8(2) - 5
y = -8 + 16 - 5
y = 8 - 5
y = 3
Vertex: (2, 3)

................
Answer:
942.50
Step-by-step explanation:
First, multiply 2334.50 by 3 to get 7003.50. Then multiply 1437x3= 4311
7003.50-4311=2692.50 Then take away 1750. 2692.50-1750=942.50

The endpoints of a line segment AB are (1, -6) and (5, -6). The equation of a line BC is
y=x-11. Is triangle ABC a right triangle? Justify your answer.
No, triangle ABC is not a right triangle. The equation of a line BC "y=x-11" is a line with slope of 1, which means it has an angle of 45 degrees with respect to the x-axis. The segment AB has a slope of 0, which means it is parallel to the x-axis. A right triangle's legs must be perpendicular, therefore a line with a slope of 1 and a line with a slope of 0 cannot be the legs of a right triangle.
A RIGHT TRIANGLEA right triangle is a triangle in which one of the angles is 90 degrees. In order for a triangle to be a right triangle, the two sides (or legs) that form the 90-degree angle must be perpendicular to each other. Perpendicular lines have slopes that are negative reciprocals of each other.
In this case, the equation of the line segment AB is "y = -6", which means it is parallel to the x-axis. The slope of a line parallel to the x-axis is 0. On the other hand, the equation of the line BC is "y = x - 11", which means it has a slope of 1. A slope of 1 means that the line is at a 45 degree angle with respect to the x-axis.
Since the slopes of the two lines are not negative reciprocals of each other (0 and 1), the legs of the triangle cannot be perpendicular. Therefore, triangle ABC cannot be a right triangle.

If 7 is an element in the domain of f(x)= 6x-18/2, what is the corresponding element in the range?
The corresponding element in the range when 7 is an element in the domain is f(7)=33
Step-by-step explanation:
Given that the 7 is an element in the domain of f(x)
The function f is defined by f(x)=6x-18/2
To find the corresponding element in the range:
That is put x=7 in the given function f(x)
Therefore f(x) becomes
f(7) = 6(7)-18/2
=42-18/2
=42-9
=33
Therefore corresponding element in the range when 7 is an element in the domain is f(7)=33

Which set of angle measures can be the angle measures of a triangle?
A. 90°, 45°,46°
B. 10°,10°,160°
C. 28°,12°,120°
Please help if you can..
Answer:
B. 10°, 10°, 160°
Step-by-step explanation:
The rule with triangles is that the angles combined may only ever add to 180°
So, lets add to be sure.
A. 90° + 45° + 46° = 181°
B. 10° + 10° + 160° = 180°
C. 28° + 12° + 120° = 160°

Solve the inequality x + 2 1/2 > -1/2. Graph the solution set on a number line.show your work.
Answer:
x > - 3
Step-by-step explanation:
x + 2[tex]\frac{1}{2}[/tex] > - [tex]\frac{1}{2}[/tex] First turn 2[tex]\frac{1}{2}[/tex] into an fraction since its easier. So it becomes [tex]\frac{5}{2}[/tex]
x + [tex]\frac{5}{2}[/tex] > - [tex]\frac{1}{2}[/tex]
- [tex]\frac{5}{2}[/tex] - [tex]\frac{5}{2}[/tex] Do inverse operations, so subtract [tex]\frac{5}{2}[/tex] from both sides.
x > - [tex]\frac{6}{2}[/tex] Combine - [tex]\frac{5}{2}[/tex] with - [tex]\frac{1}{2}[/tex], which gives us - [tex]\frac{6}{2}[/tex]
x > - 3 Since we know that 6 divided by 2 is 3.
This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)
<-------------O--------------------------------------------------->
-5 -4 -3 -2 -1 0 1 2 3 4 5
So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.

-2x+20y=-18
8x+10y=-18
Answer:
x = -1
y = -1
Step-by-step explanation:
This is a system of equations- the set up of the problem lends well to using the elimination method. There are always many ways of solving a system of equations, both in methods and different strategies within each method. The problem isn't necessarily complete but I can assume you're being asked to solve for x and y values.
divide the first equation by -2. this means we can use elimination to cancel out the y value, and is also our simplest option (rather than multiplying the second equation by -2.
-2x + 20y = -18 --> x - 10y = 9
x - 10y = 9
8x + 10y = -18
Using the elimination method to essentially add the parts of the equations together, this comes out to 9x = -9 , meaning x = -1 .
We can then return to our original equations, and substitute -1 for x (either equation will work, but the second one is simpler and therefore the better option).
8 (-1) +10y = -18
-8 + 10y = -18
10y = -10
y = -1
CHECKING
Substitute both x and y values back into the original equations to check them. the sides should be equal if our values are correct.
-2 (-1) + 20 (-1) = -18
Our first equation works: 2 - 20 = -18
8 (-1) + 10 (-1) = -18
The second equation works as well: -8-10= -18
Select the interval where the graph h is negative.
Answer: C
Step-by-step explanation:
Based on the graph, we know that it is negative if it is under the x-axis. It is also indicated by the negative labels.
A: incorrect
Looking at choice A, it says the interval is from -3<x<-2. This means we have to find x=-3 and x=-2. On the graph, that interval is above the x-axis, so it is positive, not negative.
B: incorrect
Looking at choice B, it says the interval is from 2<x<3. This means we have to find x=2 and x=3. On the graph, that interval is above the x-axis, so it is positive, not negative.
C: correct
Looking at choice C, it says the interval is from 4<x<5. This means we have to find x=4 and x=5. On the graph, that interval is under the x-axis, so it is negative.
Therefore, C is the correct answer.

Step-by-step explanation:
we are given the endpoint i.e P and Q of a line segment
we want to figure out the Midpoint of the Line segment
in order to do so we can use Midpoint formula given by
[tex] \displaystyle M = \bigg( \frac{ x_{1} + x_{2} }{2} , \frac{ y_{1} + y_{2}}{2} \bigg)[/tex]
so let
[tex]x_1=-2\\x_2=8\\y_1=-2\\y_2=4[/tex]
substitute
[tex] \displaystyle M = \bigg( \frac{ - 2 + 8}{2} , \frac{ - 2 + 4}{2} \bigg)[/tex]
simplify addition:
[tex] \displaystyle M = \bigg( \frac{ 6}{2} , \frac{ 2}{2} \bigg)[/tex]
simplify division:
[tex] \displaystyle M = ( 3,1 )[/tex]
hence,
the Midpoint of the line segment is (3,1)

Answer:
184cm
Step-by-step explanation:
to find the area of the triandles
4 times (half of 6 ) 3 = 12 divided by 2 = 6 + 6 ( because there are two right triangles making up one side ) so one side is 12cm add the other side 12 +12 = 24cm
To find the left and right sides mutipy length times width 10 x 5 = 50 add the oher side 50 + 50 = 100
To fide the bottom rectangle do the same thing but 10 x 6 = 60
so add everything together 24+100+60 = 184cm

Answer:
The value of x is 2/7 or 0.285
Step-by-step explanation:
Here, we will make equivalent expressions in the equation that all have equal bases.
6²⁽⁶ˣ⁻¹⁾ = 6⁵ˣ
Since, The bases are the same i.e., 6. So, exponent are also same
2(6x - 1) = 5x
Solve for x
12x - 2 = 5x
12x - 5x - 2 + 2 = 5x - 5x + 2
7x = 2
7x/7 = 2/7
x = 2/7 = 0.285
Thus, The value of x is 2/7 or 0.285
For verification
36⁶ˣ⁻¹ = 6⁵ˣ
36⁶⁽⁰°²⁸⁵⁾ ⁻ ¹ = 6⁵⁽⁰°²⁸⁵⁾
36¹°⁷¹ ⁻ ¹ = 6¹°⁴²⁵
36⁰°⁷¹ = 6¹°⁴²⁵
12.7 = 12.7
Hence, L.H.S = R.H.S

The measures of the three angles of a triangle are in the ratio of 1:2:2. Find their measures.
Answer:
36°, 72°, and 72°
Step-by-step explanation:
The interior angles of a triangle will always add to 180°.
Let's say the smallest angle is x, then the other two angles are both 2x.
x+2x+2x=180
5x=180
x=36
If our angles are x, 2x, and 2x, and we know x is 36, then the answer is:
36°, (2*36)°, and (2*36)°, which equals
36°, 72°, and 72°
Check: 36+72+72=180

If the m<1 = 17x - 30, and the <2 = 7x + 18, what is the value of x?
Answer:
X=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
17x−30+7x+18=180
17x+−30+7x+18=180
(17x+7x)+(−30+18)=180(Combine Like Terms)
24x+−12=180
24x−12=180
Step 2: Add 12 to both sides.
24x−12+12=180+12
24x=192
Step 3: Divide both sides by 24.
X=8
