c) 2x + 3y - 4x
Answers
Hello!
2x + 3y - 4x
= 2x - 4x + 3y
= -2x + 3y
= 3y - 2x
2x - 4x = -2x
Now, we can rewrite our expression with our new value:
-2x + 3y
Because there are no more like terms, this equation can’t be simplified further. Therefore, -2x + 3y is the final expression.

Answer:
The probability of landing a number greater than 2 is 3/4. The probability of landing a number less than 3 is 1/4.
Step-by-step explanation:
3 out of the 4 numbers are greater than 2. 1 out of the 4 numbers is less than 3.
Because sides 4 and 5 is 50% and the other half is also 50% but since it wants lower than 3 it would be half of 50% = 25%
The value of a classic car produced in 1972 can be modeled by the function V (t) = 19.25t^2 -440t + 3500, where t is the number of years since 1972. Part A. In What year does the car's value start to increase? Part B. Will the car's will ever begin to decrease? Assume it follows its modeled value.
Answers
The value of a classic car produced in 1972 can be modeled by the given function, the car's value starts to increase after 12 years since 1972, which would be in the year 1972 + 12 = 1984.
To discover the year whilst the car's fee begins to increase, we want to determine the factor at which the spinoff of the function V(t) modifications from poor to advantageous. The spinoff represents the fee of alternate of the function.
V'(t) = 2 * 19.25t - 440
2 * 19.25t - 440 > 0
38.5t - 440 > 0
38.5t > 440
t > 440 / 38.5
t > 11.428
Since t represents the wide variety of years seeing that 1972, we round up to the closest whole variety, which gives us t > 12.
Therefore, the car's value starts to increase after 12 years since 1972, which would be in the year 1972 + 12 = 1984.
Since the equation for the automobile's fee, V(t), is a quadratic characteristic with a fine coefficient for the [tex]t^2[/tex] term (19.25), the parabola opens upwards.
Thus, this manner that the car's fee will in no way begin to lower but will maintain to growth or continue to be constant over the years in step with the modeled price.

PLEASE HELPPPP
Answers
Answer:
24
they each will need to fill their bottle 24 times (48 times in total)
Step-by-step explanation:
There are 768 ounces in 6 gallons.
If each bottle carries 16 ounces in total to fill up the tank it would take 48 bottles. ( 48*16=768)
There is two students though, so you split it. (48/2=24)
Therefore each student need to fill there bottle 24 times to fill up the tank.

8.) For these we multiply left to right
(32) times (-2) to get (-64)
Then we multiply

A glide reflection is a transformation that is made up of a translation and a reflection across a line the is parallel to the direction of the translation.
A. Graph triangle DEF with vertices D(1,-1) E(7,-3) F(2,-7)

C. Are the two figures congruent?
Answers
Answer:
m
Step-by-step explanation:k
The vertices of the image triangle after the glide reflection are D'(1, 7), E'(7, 5), F'(2, 1) and both the triangles are not congruent
Graph of triangle DEF with vertices D(1,-1), E(7,-3), F(2,-7):
To graph the triangle, plot the given coordinates on a coordinate plane and connect the points to form a triangle.
D(1,-1), E(7,-3), F(2,-7)
Graph of triangle DEF under a glide reflection where the translation is (x,y) —> (x, y+8):
To perform the glide reflection, we first apply the translation by adding 8 to the y-coordinate of each vertex, and then we reflect the resulting triangle across a line parallel to the direction of the translation.
Translation: (x,y) —> (x, y+8)
Applying the translation to the original triangle DEF:
D(1, -1+8) = D(1, 7)
E(7, -3+8) = E(7, 5)
F(2, -7+8) = F(2, 1)
Now we have the new vertices for the translated triangle:
D(1, 7), E(7, 5), F(2, 1)
Next, we reflect this translated triangle across a line parallel to the direction of the translation. Since the direction of the translation is vertical, the reflection line will also be vertical.
The resulting image triangle after the glide reflection will have the same vertices as the translated triangle, but mirrored vertically.
The vertices of the image triangle after the glide reflection are:
D'(1, 7)
E'(7, 5)
F'(2, 1)
The original triangle DEF and the image triangle after the glide reflection are not congruent.

Answer: The y-value of the y-intercept is -5
Step-by-step explanation:
The y-intercept of a line is the point where it intersects the y-axis. In the given linear equation, y = 2x - 5, the y-intercept is the value of y when x is equal to 0.
To find the y-intercept, substitute x = 0 into the equation:
y = 2(0) - 5
y = -5
Therefore, the y-value of the y-intercept is -5.
Determine which integer in the solution set makes this true: 4x -9 = 31 S:{ -10, 5.5, 9, 10}

Answer: 10
Step-by-step explanation: 4x-9=31
4x=31+9
4x=40
4x/4=40/4
x=10
Answer: 10. 4(10)-9=31
Step-by-step explanation:
firstly, we would substitute the values given in the subset to the value of x and check which solves the equation.
When x= (-10),
4(-10) -9
= -40-9
=-49,
which does not equal 31, so it cannot be -10.
Similarly, when x=5.5,
4(5.5)-9
=22-9
= 13
which does not equal 31.
Thirdly, when x=9
4(9) -9
= 36-9
= 27
which does not equal 31.
Finally,
when x=10,
LHS 4(10)-9
=40-9
=31 RHS
Therefore x=10.

The histogram shows the number of points scored by a basketball team for one season. A histogram titled points scored in one season shows the number of games in which a certain number of points were scored. The data is as follows. 69 to 76 points: 3 games. 77 to 84 points: 6 games. 85 to 92 points: 8 games. 93 to 100 points: 1 game. According to the histogram, in what percentage of games did the team score between 77 and 92 points? Enter your answer in the box. Round your answer to the nearest percent.
Answers
Find the total number of games with points scored between 77 & 92 pts - 14
To find the percentage divide 14/18 - .777
Multiply .777*100 - 77.7
Round to 78%
Percentage of games the team scored between 77 and 92 is 77.7% .
Given data from the histogram shows the number of games that are played in the range of 77 - 92.
Total number of games played = 18
Number of games played in the range 77 - 92 = 14
Percentage of games played in the range 77-92 = (Number of games played in the range 77 - 92) / (Total number of games played) × 100
Percentage = (14)/(18) × 100

rate = distance / time
where distance is 60 miles and time is 1 hour. Therefore:

Step-by-step explanation:
r = about -2
s = about 2
-s = exactly -2
r + s = about 0
When looking at the number line, s is the farthest away right from zero, making it the variable with the most value that is at least two.
Since the expression has a choice of a negative s, it would simply mean that two would become negative two.
Since you know the values of s + r, you will know that -2 + 2 would equal to 0.
Overall-The least value would be -s
-The greatest value would be s
-The expression that is closer to zero would be s + r
