The functions which are graphed below are 1-2x51 1.4.> 1, the correct option is D.
What is a solution to a system of equations? (SOLUTION GRAPHICALLY)For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)
We are given that;
The graph of the function
Now,
Let’s apply these steps to your question. The given piecewise function has three pieces:
f (x) = {−2x, x < −1 −|x|, −1 ≤ x ≤ 1 2−x2, x > 1 f ( x) = { − 2 x , x < − 1 − | x | , − 1 ≤ x ≤ 1 2 − x 2 , x > 1
The first piece is a linear function with slope -2 and y-intercept 0. It is defined for all values of x less than -1. To graph this piece, we can use two points: (-2,4) and (-1,-2). We use an open circle at (-1,-2) because this point is not included in this interval.
The third piece is a quadratic function with vertex at (0,2). It is defined for all values of x greater than 1. To graph this piece, we can use three points: (0.5, 3/4), (1,0), and (2,-2). We use an open circle at (0.5,3/4) because this point is not included in this interval.
The final graph looks like this:
To find which option matches the given graph, we can compare their equations with the given pieces.
Option A has f(x) = -|x| when -∞ < x < ∞. This does not match any of the pieces.
Option B has f(x) = -|x| when -∞ < x ≤ -3 or -3 < x ≤ ∞. This does not match any of the pieces.
Option C has f(x) = -|x| when -∞ < x ≤ ∞. This matches only one of the pieces.
Option D has f(x) = {−2x,x<−12−x,x≥−12 f(x)=−2xx<−12−xx≥−12 . This matches none of the pieces.
Therefore, by the given graph the answer will be 1-2x51 =1.4.> 1

stay safe healthy and happy...Suppose that QRS is isosceles with base q r. Suppose also that m q equals (5x - 14(degrees and Mr equals (4x - 2)degree
PLEASE HELP ME
Answer:
<S= 88degrees
<Q = <R = 46degrees
Step-by-step explanation:
Since the base angles of the isosceles triangle are equal hence;
<Q = <R
5x - 14 = 4x -2
5x - 4x = -2 +1 4
x = -2 + 14
x = 12
Since <Q = 5x - 14
<Q = 5(12) - 14
<Q = 60 - 14
<Q = 46degrees
Also <Q = <R = 46degrees
Similarly; <S + <Q + <R =180
<S +46 + 46 = 180
<+92 = 180
<S = 180 - 92
<S= 88degrees

Answer:
15.2%
Step-by-step explanation:
There are 12 marbles in total and there are 5 red marbles, so the probability of getting a red marble is 5/12. There are now 11 marbles and there are 4 blue marbles. So the probability of getting a blue marble is 4/11.
You multiply these 2 values together.
5/12 * 4/11 = 20/132 = 0.1515
This is about 15.2%
Answer:
option b : 15.2 %
Step-by-step explanation:
5 Red , 4 Blue, 3 Yellow
Total balls = 12
[tex]Probability \ of \ choosing \ red = \frac{5C_1}{12C_1} = \frac{5}{12}\\\\Probability \ of \ choosing \ blue \ without \ replacement = \frac{4C_1}{11C_1} = \frac{4}{11}\\\\Probability \ of \ red \ and \ then \ blue = \frac{5}{12} \times \frac{4}{11} = 0.1515\\\\Probability \ in \ percentage = 0.1515 \times 100 = 15.15 = 15.2 \%[/tex]
If it costs $16.50 to bowl twice with a shoe rental and $28.50 to bowl 4 times with a shoe rental how much does the shoes cost
Answer:
Shoe rent is $4.5
Step-by-step explanation:
Let the shoe rent is "x" which will remain the same irrespective of the number of bowling and "y" is bowling.
thus, x + 2y = 16.50
Rewrite, x = 16.50 - 2y
When bowling is 4 time then:
x + 4y = 28.50
Rewrite, x = 28.50 - 4y
Now solve both equations for the value of "y".
Thus, 16.50 - 2y = 28.50-4y
-2y + 4y = 28.50 - 16.50
2y = 12
y = 6
Insert y = 6 in the x - 2y = 16.50
x = 16.50 - 2y
x = 16.50 - 2 (6)
x = $4.5
Shoe rent is $4.5

Does anybody know this?
Answer:
x = 45 °
Step-by-step explanation:
We know that the sum of all angles if right angle triangle is 180 °.
90 ° + x + x = 180°
90 ° + 2 x = 180 ° ...( combine like terms)
2 x = 180 ° - 90 °.. ( subtract 90° from 180° )
2 x = 90°
x = 90° /2 ....( divide by 2 )
x = 45 °

Describe the transformation of f(x) to g(x).
(answers and graph in picture) PLSSSS HELP
Answer: b
Step-by-step explanation:
becuz now brainliest
The transformation of a function may involve any change. The correct option is A.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units, y=f(x+c) (same output, but c units earlier)Right shift by c units, y=f(x-c)(same output, but c units late)Vertical shift
Up by d units: y = f(x) + dDown by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k × f(x)Horizontal stretch by a factor k: y = f(x/k)Given the function of f(x) as sin(x), Now it can be seen the graph of the two functions is parallel, but the function f(x) has a y-intercept of 0, while h(x) has a y-intercept of 1. Therefore, we can write,
h(x) = f(x) + 1
The function is shifted up by 1 unit.
Hence, the transformation of the function is correctly described in the first option.

Answer:
184
Step-by-step explanation:
First, note that the sides that are opposite to each other are congruent (this will come into play in a second). We can find the area of each triangle by doing 0.5(b)(h) (aka half * base* height). Since we've established tha opposite sides are congruent and the triangles are opposite to each other, they must be congruent. That means that the area is going to be the exact same for both triangles. So, we get the expression (0.5)(6)(4)(2), which comes out to 6*4 = 24. Then, to find the area of the 2 rectangles that are the sides, just do 5*10*2 = 100 square meters for both rectangles combines. Lastly, we need to find the area of the floor. The dimensions of the floor are 6 and 10, so we just do 6*10 = 60. Now, add all those numbers together. We get 100+60+24 = 184. Hope this helps! Let me know if anything is still confusing.

Terrific Tents has a new two-person tent. If the material costs $0.02 per square inch, find out how much it costs to make each two-person tent.
Answer:
$280
Step-by-step explanation:
Please find attached the image of the tent
cost of the tent = cost per square inch x total surface area of a triangular prism
total surface area of a triangular prism = (perimeter x height) + 2(area of a triangle)
Area of a triangle = 1/2 x base x height = 1/2 x 40 x 50 = 1000in²
1000 x 2 = 2000
Perimeter = 50 + 50 + 50 = 150
150 x 80 = 12,000
total surface area = 12,000 + 2000 = 14,000
Total cost = 14,000 x 0.02 = $280

which following algebraic statements are true
Answer:
All of them are true.
Step-by-step explanation:
x^2 y - z / x^2 is true. x^2, when divided by itself, cancels itself out, so the equation that is left is y - z.
For the second one, a/c + b/c is true because when you add a + b = it will change; it will be added together. the remaining c will stay the same, as it is the denominator/the same, so you keep it as it is.
For the final one, you distribute ^2 to (a+b), so they become a^2 + b^2.
This means that all of the statements are true.

What is the ratio of the length of JK to the length of MN?

Answer:
Step-by-step explanation:
Yikes. This is quite a doozy, so pay attention. We will begin by factoring by grouping. Group the first 2 terms together into a set of parenthesis, and likewise with the last 2 terms:
[tex](2d^4+6d^3)-(18d^2-54d)[/tex] and factor out what's common in each set of parenthesis:
[tex]2d^3(d+3)-18d(d+3)[/tex]. Now you can what's common is the (d + 3), so factor that out now:
[tex](d+3)(2d^3-18d)[/tex] BUT in that second set of parenthesis, we can still find things common in both terms, so we continue to factor that set of parenthesis, carrying with us the (d + 3):
[tex](d+3)2d(d^2-9)[/tex] BUT that second set of parenthesis is the difference of perfect squares, so we continue factoring, carrying with us all the other stuff we have already factored:
[tex](d+3)2d(d+3)(d-3)[/tex]. That's completely factored, but it's not completely simplified. Notice we have 2 terms that are identical: (d + 3):
[tex]2d(d+3)^2(d-3)[/tex] is the completely factored and simplified answer, choice 3)
