Write a polynomial that is a trinomial, has the coefficients 3 and 4, the variable x,
and the constant 7
Answer:
3x+4x+7
Step-by-step explanation:
First, a Trinomial consists of three terms.
so we have blank+blank+blank
Next we need to add the coefficients.
3+4+blank
Add the variables.
3x+4x+blank
And lastly, add the constant.
3x+4x+7
Good luck!
A trinomial that meets the given criteria is:
p(x) = 3*x^2 + 4*x + 7
How to get a trinomial?
A trinomial is a polynomial with 3 terms, we can write it as:
p(x) = A*x^n + B*x^k + C*x^m
Where n, k, and m, can be only natural numbers equal to or larger than zero, and A, B, and C are the coefficients.
First, we know that our trinomial has a constant 7, then one of the exponents must be 0, let's say that m = 0, then C = 7.
p(x) = A*x^n + B*x^k + 7
Now, we know that the other coefficients must be 3 and 4, so we can use:
A = 3B = 4And there are no more restrictions, so we can use any values for n and k, I will use:
n = 2k = 1.Then the trinomial becomes:
p(x) = 3*x^2 + 4*x + 7

Suppose that a line segment is translated. Which of the following is true?
The line segment's position and length change.
The line segment's position changes, but its length remains the same.
The line segment's slope changes, but its length remains the same.
The line segment's length and position remain the same.
Answer:
The line segment's position changes, but its length remains the same.
Step-by-step explanation:
When a line segment is translated, it only will move its position up, down, or to the side.
The slope and length will stay the same, but the position will change.
So, this answer is correct because the position changes but not the length.

Consider the system of equations given in slope-intercept form. y = −13x + 17, y = 5x - 23 The solution seems to be about (8, 14). Use the graphing calculator to find the exact values for the intersection point. What is the solution to this system of equations?
The exact values for the intersection point is (20/9, -107/9)
Given the system of equation expressed as;
y = −13x + 17;
y = 5x - 23
Since they are both y-values, we will equate both expressions to have:
-13x + 17 = 5x - 23
-13x - 5x = -23 - 17
-18x = -40
x = 40/18
x = 20/9
Substitute x = 20/9 into equation 2:
y = 5x - 23
y = 5(20/9) - 23
y = 100/9 - 23
y = -107/9
Hence the exact values for the intersection point is (20/9, -107/9)

Answer:
[tex]X = \begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex]
Step-by-step explanation:
The question we have at hand is, in other words,
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}\left(X\right)=\begin{bmatrix}8&20\\ \:3&7\end{bmatrix}[/tex] - where we have to solve for the value of [tex]X[/tex]
If we have to isolate [tex]X[/tex] here, then we would have to take the inverse of the following matrix ...
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}[/tex] ... so that it should be as follows ... [tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}^{-1}[/tex]
Therefore, we can conclude that the equation as to solve for " [tex]X[/tex] " will be the following,
[tex]X=\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] - First find the 2 x 2 matrix inverse of the first portion,
[tex]\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}[/tex] = [tex]\frac{1}{\det \begin{pmatrix}4&2\\ 1&1\end{pmatrix}}\begin{pmatrix}1&-2\\ -1&4\end{pmatrix}[/tex]= [tex]\frac{1}{2}\begin{bmatrix}1&-2\\ -1&4\end{bmatrix}[/tex] = [tex]\begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}[/tex]
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
[tex]X = \begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] ,
[tex]X = \begin{pmatrix}\frac{1}{2}\cdot \:8+\left(-1\right)\cdot \:3&\frac{1}{2}\cdot \:20+\left(-1\right)\cdot \:7\\ \left(-\frac{1}{2}\right)\cdot \:8+2\cdot \:3&\left(-\frac{1}{2}\right)\cdot \:20+2\cdot \:7\end{pmatrix}[/tex] - Simplifying this, we should get ...
[tex]\begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex] ... which is our solution.

PLEASE HELP ASAP Brent is driving to a conference in another state. Three hours after leaving his home and beginning his drive, Brent is still 470 miles from his destination. After another 4 hours of driving, Brent is 258 miles from his destination. After 9 hours of driving, Brent plans to stop at a hotel for the night and begin his trip again 12 hours later. If Brent’s average speed had been faster or slower on his trip, what features of the graph would change and how would they change in each situation. Explain your answers. Type your response here: Brent decided that he needed to reach his destination in 11 hours of driving. What would his average rate of speed, rounded to the nearest hundredth, need to be to accomplish this? Show your work.
Answer:
The average rate of speed needed is 76 miles/hr.
Step-by-step explanation:
From the provided data, we can conclude two points:
Brent is 470 miles from his destination after driving for 3 hours, (3, 470).Brent is 258 miles from his destination after driving for 7 hours, (7, 258).Form an equation representing the distance left to Brent's destination, d, based on the amount of time he has spent driving, t.
[tex](d-d_{1})=\frac{d_{2}-d_{1}}{t_{2}-t_{1}}\cdot (t-t_{1})\\\\(d-470)=\frac{258-470}{7-3}\cdot (t-3)\\\\d-470=-53(t-3)\\\\d=-53t+159+470\\\\d=629-53t[/tex]
The speed of a vehicle is:
[tex]speed=\frac{distance}{time}\\\\\Rightarrow distance=speed\times time[/tex]
So distance is directly proportional to the speed, i.e. as speed increases the distance covered also increases and as speed decreases the distance covered also decreases.
So, if Brent’s average speed had been faster or slower on his trip, the distance left to be covered would decrease or increase accordingly.
Consider the provided information:
3 hours of driving → 470 miles left
7 hours of driving → 258 miles left.
That in 4 hours Brent covered 212 miles.
Speed at which he was driving was:
[tex]speed=\frac{distance}{time}=\frac{212}{4}=53\ \text{miles/hr}[/tex]
Now it is provided that after 9 hours of driving, Brent plans to stop at a hotel for the night.
That is he drove for another 2 hours at the same speed, i.e. 53 miles/hr.
Compute the distance covered between 7 hour to 9 hour as follows:
[tex]distance = speed\times time=53\times 2=106\ \text{miles}[/tex]
Remaining distance = 258 - 106 = 152 miles.
If Brent wants to reach his destination in 11 hours of driving then he has to cover the remaining 152 miles in the next 2 hours.
Compute the speed as follows:
[tex]speed=\frac{distance}{time}=\frac{152}{2}=76\ \text{miles/hr}[/tex]
Thus, the average rate of speed needed is 76 miles/hr.

Please help its eighth math!
Answer:
t and u are parallel lines
s and t are also parallel lines
Step-by-step explanation:
If two parallel lines are cut by a transversal ,
then in it
pair of alternate angle are equals, similarly vice versa
if pair of alternate angle are equals then lines are parallel
pair of corresponding angles are equal and vice-versa
for example
in the given problem
if line t and u are parallel (note we have assumed this to give example of parallel lines)
then angle 7 and 9 are called alternate angles
pair of angles 5 and 9 are corresponding angles.
________________________________________________
given
∠8 = ∠10 which are alternate angles for line t and u and s is transversal for it,
thus t and u are parallel lines
___________________________
∠1 = ∠3 as they vertically opposite angles
and we know that pair of vertically opposite angles are equal
given
∠1 = ∠7
thus
∠3 = ∠7
as pair of angles ∠3 and ∠7 are corresponding angles. and are equal and hence line s and t are also parallel.

Parallelogram H G J L is shown. Diagonals are drawn from point H to point J and from point G to point L and intersect and point K. In parallelogram HGJL, HK = c – 7, JK = 3c – 33, and GK = c + 12. What is the length of segment GL? GL = units
Answer:
50 units.
Step-by-step explanation:
It is given that HGJL is a parallelogram and diagonals intersect each other at point K.
[tex]HK=c-7,JK=3c-33,GK=c+12[/tex]
We now that diagonals of parallelogram bisect each other. So,
[tex]HK=JK[/tex]
[tex]c-7=3c-33[/tex]
[tex]33-7=3c-c[/tex]
[tex]26=2c[/tex]
Divide both sides by 2.
[tex]13=c[/tex]
Now,
[tex]GK=c+12=13+12=25[/tex]
Diagonals of parallelogram bisect each other. So,
[tex]GL=2(GK)=2(25)=50[/tex]
Therefore, the measure of GL is 50 units.

There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup. Based on this, about how many grains of sand would there be in a 5-gallon container (note: 1 gallon = 16 cups). Write the result in scientific notation.
Answer:
[tex]3.5725 * 10^5[/tex]
Step-by-step explanation:
Given
There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup.
Required
How many grains of sand would there be in a 5-gallon container?
Let x represent the number of grains in 5 gallon; So, From the question, we have that;
8 cups = 3.5725 * 10^4
5 gallon = x
Cross Multiply
x * 8 cups = 5 gallon * 3.5725 * 10^4
Recall that 1 gallon = 16 cups
[tex]x * 8\ cups = 5 * 16\ cups * 3.5725 * 10^4[/tex]
[tex]x * 8 = 5 * 16 * 3.5725 * 10^4[/tex]
Divide both sides by 8
[tex]\frac{x * 8}{8} = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = 5 * 2 * 3.5725 * 10^4[/tex]
[tex]x = 10 * 3.5725 * 10^4[/tex]
[tex]x = 3.5725 * 10^5[/tex]
Hence, the number of grains of sand in 5 gallon is [tex]3.5725 * 10^5[/tex]
