The resultant expression is -7y+3y is -4y which could represent the combined terms.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question as follows:
-7y² + 2y³ – 7y + 4y³ + 6y² + 4y² + 3y
We have to determine the resultant expression that could represent the combined terms.
As per the question, we have
⇒ -7y² + 2y³ – 7y + 4y³ + 6y² + 4y² + 3y
Rearrange the terms likewise variables,
⇒ 2y³+4y³ -7y²+10y²-7y+3y
Here 2y³+4y³ is 6y³, -7y²+10y² is 3y², and 10y² is 6y²+4y²
⇒ -7y+3y is -4y
Therefore, the resultant expression is -7y+3y is -4y.

Tyrell went to the park to go jogging. The beginning of the running path has an elevation of -2 feet. The highest elevation on the jogging path is 14 feet. What is the difference in elevation between the highest point and the beginning of the path? Make sure you write down the highest point first then take away the negative two.
Answer:
16 ft
Step-by-step explanation:
Difference in a math question always signifies that we are subtracting. When finding the difference between an elevation you need to subtract the highest point first from the lowest point or starting point. Therefore in this scenario, we subtract 14 feet which is the highest point from the starting point which is -2 ft. Since the starting point is at a negative elevation, the negatives will cancel out and becomes a positive.
14 - (-2) = x ... negative cancel out and become a positive or addition
14 + 2 = x
16 ft = x
Finally, we can see that the difference between these two points is 16 ft.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+157x+124 y=−16x 2 +157x+124
Answer:
Rocket will hit the ground in 10.55 seconds.
Step-by-step explanation:
Let be [tex]y = -16\cdot x^{2}+157\cdot x +124[/tex], where [tex]x[/tex] and [tex]y[/tex] are time after launch and the height of the rocket, measured in seconds and meters, respectively. To find the time that the rocket will hit the ground, we need to equalize height to zero and solve the resulting expression:
[tex]-16\cdot x^{2}+157\cdot x + 124 = 0[/tex]
The quadratic function can be solved analitically by Quadratic Formula, that is to say:
[tex]x = \frac{-157\pm \sqrt{157^{2}-4\cdot (-16)\cdot (124)}}{2\cdot (-16)}[/tex]
Roots of the polynomial are, respectively:
[tex]x_{1} \approx 10.55\,s[/tex], [tex]x_{2}\approx -0.74\,s[/tex]
Only first root offers to us a reasonable solution. Hence, we conclude that rocket will hit the ground in 10.55 seconds.

Step-by-step explanation:
Peyton go shopping she finds T-shirts one +24.97 and the other cost 13.75 she needs to know if she has enough money to buy both shirts using mental math she round $24.97-$25 and exit 213.75 to get 38.75 how does Peyton need to compensate find the exact all of the Two shirts
Answer: Subtract 0.03.
Step-by-step explanation:
given data:
Cost of T-shirt one = $24.97.
cost of T-shirt two = $13.75.
peyton rounded the cost of the first T-shirt up to $25 ( by adding $0.03 ). The addeded the cost of the second shift to arrive at a total cost of $38.75 for both.
to find the exact amount of the two shirts, peyton needs to subtract 0.03 from the total amount.
= $38.75 – 0.03
= $38.72
The original amount of both T-shirt is $38.72.

Caroline's Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?
Answer:
The answer is 12
Step-by-step explanation:
All you had to do is subtract 26.95 by 8.95 which is 18, and then you would divide 18 by 1.50 and your answer is 12!

If the sum of the square of the number and 4 time the number is 21,
what is the number?
Answer:
I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”
If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.
This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.

The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis.
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis.
Answer:
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis. ⇒ False
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis. ⇒ False
Step-by-step explanation:
Let us explain the reflection about the axes
If a graph is reflected about the x-axis, then the y-coordinates of all points on it will opposite in signEx: if a point (2, -3) is on the graph of f(x), and f(x) is reflected about the x-axis, then the point will change to (2, 3)
That means reflection about the x-axis change the sign of yy = f(x) → reflection about x-axis → y = -f(x)If a graph is reflected about the y-axis, then the x-coordinates of all points on it will opposite in signEx: if a point (-2, -5) is on the graph of f(x), and f(x) is reflected about the y-axis, then the point will change to (2, -5)
That means reflection about the y-axis change the sign of xy = f(x) → reflection about y-axis → y = f(-x)Now let us answer our question
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the x-axis.
It is False because reflection about x-axis change sign of y
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the x-axis
The graph of y = -f(x) is a reflection of the graph of y = f(x) in the y-axis.
It is False because reflection about y-axis change sign of x
The graph of y = f(-x) is a reflection of the graph of y = f(x) in the y-axis

$ 44616
Step-by-step explanation:Hi there !
What will be the price of the next model ?
$39000 + $39000×14.4% =
= $39000 + $39000×0.144
= $39000(1 + 0.144)
= $39000×1.144
= $ 44616
