Answer:
$4 on average
Step-by-step explanation:
A fair coin has a 50/50 chance of being heads/tails.
You have a 50% chance to get heads and win $8.
If you flip the coin twice then it is likely you get heads once and tails once. So, on average, $8 divided by 2 flips = $4.

Determine the solution to the system of equations graphed below and explain your reasoning in complete sentences. g(x) = -2x - 3 and f(x) = Ix+1I - 4
Answer:
(0,3)
Step-by-step explanation:
It is where the lines intersect
The value of the g(x) is equal to the value of f(x). Then the solution of the equation is at (0, -3).
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
The given expression are as follows
g(x) = -2x - 3 and f(x) = Ix+1I - 4
For the solution of the system, the value of the g(x) is equal to the value of f(x). Then we have
[tex]\begin{aligned} \rm g(x) &= \rm f(x)\\\\\rm -2x - 3 &= \rm x + 1 - 4\\\\-\rm 2x - 3 &= \rm x - 3\\\\\rm 3x &= 0\\\\\rm x &= 0 \end{aligned}[/tex]
Then the g(x) will be
g(x) = -2(0) - 3
g(x) = - 3
Then the solution of the equation is at (0, -3).

Tri scored a total of 31 points in the basketball game, and he scored p points in the second half of the game. Write an expression to determine the number of points he scored in the first half of the game. Then, find the number of points he scored in the first half of the game if he scored 7 points in the second half of the game
Please No Fake Answers this QUESTION IS ALOT OF POINTS ON A TEST
Answer:
If he scored x points in the first half, then x + p = 31
Answer:
expression: y = 31 - pHe scored 24 points in the first half.expression:
first half points + second half points = total points obtained
Let first half points be y
y + p = 31
y = 31 - p ......this is the expression.
solve:
y = 31 - p
y = 31 - 7
y = 24 points
What type of transformation is the image portraying?
options:
Dilation
Reflection
Rotation
Translation
Answer:
Reflection
Step-by-step explanation: A reflection is a transformation that acts like a mirror.
Answer:
Reflection
Step-by-step explanation:
Translations are a horizontal and/or vertical movement of a shape. In this case, the points wouldn't match up. A dilation is either growth or reduction, which this pretty obviously is not. A rotation also wouldn't properly match the points up. If we reflect this shape across a line directly in between the two, all the points will match up.

Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.

how to know if an angle is congruent?
Answer:
Two angles are congruent if they have the same measure. If you didn't already know, when two lines intersect the vertical angles formed are congruent. For example, all the angles in a square are congruent. All the angles in a regular pentagon are 108°, therefore all the angles are congruent because they are the same.
Step-by-step explanation: Hope this helps:).........if not sorry:(
Answer:
Well, AN angle (as you've stated in your question) can't, by definition, be congruent; you need at least two angles. Once that condition is met, then we can say that two angles are congruent if they have the same measure.

Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).

The limits are important in calculus and mathematical analysis and can be used to define integrals, derivatives and continuity. The limit of the given function is 4.
What is limit of a function?In mathematics, the limit is defined as the value that a function approaches the output for the given input values. It is used in the analysis process and it always concerns about the behaviour of the function at a particular point.
The upper and lower limits are used to define the definite integrals whereas the indefinite integrals are defined without using the limits and it have an arbitrary constant while integrating the function.
The limit of the given function is:
limₓ → -1 (2x² + 3x + 5)
(2 × (-1)² + 3 × (-1) + 5)
(2 × 1 + (-3) + 5) = ( 2 - 3 + 5)
= 4
So the limit of the given function is 4.

The rule T⟨4, −1⟩ is used on the preimage point (2, −7). What is the image point?
The image point for the given rule and preimage is (6 - 8)
What is the image point?When we apply a rule T<a, b> to a preimage point (x, y) we get the image (x + a, y + b), so this is like a translation.
So if we apply the rule T<4, -1> to the preimage point (2, -7), the image will be:
(2 + 4, - 7 + (-1)) = (6 - 8)
Concluding, the image point is (6 - 8)

What is the correct justification for the first step in solving this equation? 3(x - 4) + 1 = 12x
Answer:
x = -11/9
Step-by-step explanation:
3(x-4) + 1 = 12x
Step 1: Use distributive property
3*x - 3*4 + 1 = 12x
3x - 12 + 1 = 12x
Step 2: Combine like terms
3x - 11 = 12x
Step 3: Subtract '3x' from both sides
-11 = 12x - 3x
-11 = 9x
Step 4: Divide both sides by 9
-11/9 = x
Answer:
Solve the first part in Parenthese
Step-by-step explanation:

3x-11=0x
