Answer:
Step-by-step explanation:
I believe you're refering to an "axis of symmetry." This is most often seen in quadratic equations. If the parabolic graph opens up or down, the axis of symmetry is the vertical line passing through the vertex, and the graph is symmetrical about this axis. The same applies to a parabolic graph that opens left or right.
If y = ax^2 + bx + c, the equation of the axis of symmetry is x = -b / (2a).

Given:BK=CH Which additional congruence statement could you use to prove that ∆BJK ≅ ∆CFH by the HL Theorem?
Answer:
B
Step-by-step explanation:
The hl theorem says that if we have two right triangles that have a congruent hypotenuse and a congruent leg, the two triangles are congruent
in this case the exercise says the two leg are congruent, so we have to say that the two hypotenuse are congruent
So
JB congruent to FC
Solve the following system of equation using any method.
3x+3y=12
2x+4y=16
X = and Y=
Answer:
X=0
Y=4
Step-by-step explanation:
3x=12-3y
x=4-y
Plug 4-y in for x in the other equation:
2(4-y)+4y=16
8-2y+4y=16
2y=8
y=4
If x=4-y and y=4, x=4-4=0
Answer this question so i dont fall victim to a siezure/heart attack from stress
Answer:
Length = 12 feet, Width = 10 feet
Step-by-step explanation:
Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.
We know that the perimeter of a rectangle is given by,
P=2(length+width)
P=2(x+y)
It is given that, the length of the bedroom is 2 more than the width, so,
x=y+2
Putting the values in the equation of perimeter we get,
44=2((y+2)+y)
44=2(2y+2)
44/2 =2y+2
22=2y+2
2y=22−2
y= 20/2 =10
Therefore, x=y+2=10+2=12
Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.
What is the recursive rule for the sequence? -1,-0.5,0,0.5,1,...
9514 1404 393
Answer:
C
Step-by-step explanation:
The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...
[tex]a_n=a_{n-1}+0.5[/tex]
is the appropriate one. This matches choice C.
__
Additional comment
Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

Mr. Boone estimates that it will take him 48 minutes to run 8 miles. It
actually takes him 60 minutes. What was his percent error? *
18%
20%
25%
30%
Answer:
20%
Step-by-step explanation:
The formula to find percent error is the absolute value of the actual value (60) minus the approximate value (48) divided by the actual value (60) times 100. So first we calculate 60 - 48 which is 12 then divide 12 by 60 which gives us 0.2 and finally multiply by 100 which gives us the answer of 20%

Each day, Robert eats 40% of the pistachios left
in his jar at that time. At the end of the second
day, 27 pistachios remain. How many pistachios
were in the jar at the start of the first day?
Answer:
At the beginning of the first day there were 75 pistachios in the jar.
Step-by-step explanation:
Given that each day, Robert eats 40% of the pistachios left in his jar at that time, and at the end of the second day, 27 pistachios remain, to determine how many pistachios were in the jar at the start of the first day you must perform the following calculations:
100 - 40 = 60
60 = 27
100 = X
100 x 27/60 = X
2700/60 = X
45 = X
60 = 45
100 = X
100 x 45/60 = X
4500/60 = X
75 = X
Therefore, at the beginning of the first day there were 75 pistachios in the jar.

Jenny needs 1/2 of a stick of butter for a recipe. She cuts the half stick of butter into four equal pieces what portion of the whole stick of butter is each of the pieces I need to show my work plz
Answer:
1/16
Step-by-step explanation:
1/2 of 1/2 is 1/4 then 1/4 of 1/4 is 1/16
If Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
It is given that Jenny needs 1/2 of a stick of butter for a recipe. She cuts the half stick of butter into four equal pieces.
The portion of the whole stick of butter in each of the pieces is found as,
= (1/2) / 4
=1/8
Thus, if Janie cuts half a stick of butter into four equal pieces, one-eighth (1/8) portion of the whole stick of butter is in each of the pieces.

Researchers give one group a new cold medicine and compare them with to a group that takes no medicine. what is the group that is not given any medicine?
A. the control group in an experiment
B. the experimental group in a survey study
C. the experimental group in an experiment
D. the control group in an observational study
Answer:
A. the control group in an experiment
Step-by-step explanation:
Researchers give one group a new cold medicine and compare them with to a group that takes no medicine. The group that is not given any medicine is the control group in an experiment.
Who are researchers?Researchers are those who do research on something i.e. systematics and deep investigation into something.
What is control group?Control Group is that group in research which does not take any medication or untreated group.
During the research while a new type of medicine is to be tested, the group that receives the medication or being tested is called the experimented group and the group that does not receive the treatment is called the control group.
Hence, we can say that the group that is not given any medicine is the control group in an experiment.

Which equation has a graph that is a parabola with a vertex at (-2, 0)?
O y=-22²
O y = (x + 2)2
O y = (x - 2)2
Oy=x²-2
Answer: y = (x+2)^2
Aka: B
Step-by-step explanation:
Did it on edge just now !
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).
Option B is the correct answer.
What is a parabola?A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.
The equation of a parabola:
y = a(x-h)^2 + k
We have,
The equation that has a graph that is a parabola with a vertex at (-2, 0) is
y = (x + 2)².
The general equation for a parabola is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
Comparing this general equation to y = (x + 2)²,
We can see that h = -2 and k = 0, which means that the vertex of the parabola is (-2, 0).
Therefore,
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).
