The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).
As per the question, the small integer is x. So, the large integer will be (x + 8).
Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -
x (x + 8) = 308
Performing multiplication on Left Hand Side of the equation
x² + 8x = 308
Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -
x² + 8x – 308 = 0
On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.
x² + 8x – 308 = 0
x² + 22x - 14x – 308 = 0
x (x + 22) - 14 (x + 22) = 0
(x + 22) (x - 14) = 0
x = -22 and 14
Since the numbers are negative, hence, value of small number is -22.
Large number = -22 + 8
Large number = -14
Thus, the small and large number is -22 and -14.
Therefore, the correct equation is x² + 8x – 308 = 0.

Terrance's homework grade was a 72, his project grade was an 80 and his exam grade was an 82.
Homework is worth 10% of the final grade, the project was worth 50%, and the exam was worth 40%.
What was Terrance's final grade?
Answer:
80%
Step-by-step explanation:
home work = 10%
project grade = 50%
final exam = 40%
so
homework = 72
100=10
72=? cross multiply and get 7.2%
project grade = 80
100 = 50
80 = ? cross multiply and get 40%
final exam = 82
100 = 40
82 = ? cross multiply and get 32.8%
then add them altogether getting a total of 80%.
Select the correct answer. A model rocket was launched from the top of a building. The rocket's approximate height can be modeled by the quadratic equation h = -4.9t2 + 53.9t + 127.4, where h is the rocket's height, in meters, after t seconds. When factored, this equation is h = -4.9(t - 13)(t + 2). What is a reasonable time for it to take the rocket to land on the ground? Answer A 11 seconds Answer B 13 seconds Answer C 2 seconds Answer D 15 seconds
Answer:
13 seconds.
Step-by-step explanation:
Given
[tex]h = -4.9(t - 13)(t + 2).[/tex]
Required
Determine a reasonable solution for t
To do this, we equate h to 0.
[tex]h = -4.9(t - 13)(t + 2).[/tex] becomes
[tex]0 = -4.9(t - 13)(t + 2).[/tex]
Divide through by -4.9
[tex]0 = (t - 13)(t + 2).[/tex]
Reorder the expression
[tex](t - 13)(t + 2) = 0.[/tex]
Split
[tex]t-13 = 0[/tex] or [tex]t + 2 = 0[/tex]
This gives:
[tex]t = 13[/tex] or [tex]t = -2[/tex]
But time can't be negative, So:
[tex]t = 13[/tex]

Answer:

I'm not sure how the answer is 4.5 but I'm pretty sure this is right unless I'm missing something
Step-by-step explanation:
So we need to find how much shorter is the short line compared to the longer one. Basically we need a scale factor, for this we can use the side lengths already given to us, 10 and 15. So u can choose either enlarge the short line or shorten the longer one.
If u want to enlarge the short line then do 15/10 which is 3/2 which u will then multiply the shorter line's equation with it, if u want to shorten the longer line then do 10/15 which is 2/3 and multiply the longer lines equation with it.
I'll be using the 3/2 one cause why not:
3/2(x + 6) = 4x + 3
3/2x + 18/2 = 4x + 3
multiply the entire equation with 2 to make 3/2 no longer a fraction
(3/2x + 18/2 = 4x + 3)2
6/2x + 18 = 8x + 6
3x + 18 = 8x + 6
subtract 18 from both sides
3x = 8x - 12
subtract 8x from both sides
-5x = - 12
divide -5 from both sides
x = 2.4
U can input x into the equation to check:
3/2(2.4 + 6) = 4(2.4) + 3
12.6 = 12.6, it's right
Mason made 19 more shots during
the basketball season than Noah.
Peter made 10 shots less during
the season than Noah. If Peter
made 23 shots, how many shots did
Mason make?
Answer:
52
Step-by-step explanation:
Let the number of shots Mason made be x.
No. of shots (Mason) = x
No. of shots (Noah) = x-19
No. of shots (Peter) = x-19-10
= x-29
x-29 = 23
x = 23 + 29
x = 52
Thus, Mason made 52 shots.

Answer:
(-2,4)
Step-by-step explanation:
When you reflect over y = x, the x and y change places. F' is at (4,-2) .
Answer: (-2, 4)
Step-by-step explanation:
Swap x and y coordinates since you're reflecting over y=x.
(4, -2)==>(-2, 4) ==> The slope between these two points should be -1(y=-x). That way, you know the graph is being reflected over y=x.
m=(y2-y1)/(x2-x1)
m=(4-(-2))/(-2-4)
m=(4+2)/(-6)
m=6/(-6)
m=-1 ==> These two points are confirmed to be reflected over the line y=x.
Old coordinates: (-2, 4)

On his last test Julie stated that the point (-3 ,4) was a solution to the system of equations below explain whether she was correct by using complete sentences and work to support your claim -3x+4y=25 and y= -3x+4
Answer:
(-3/5, 29/5)
Step-by-step explanation:
Given the simultaneous equation;
-3x+4y=25...... 1
y= -3x+4 ..... 2
We are to confirm if (-3, 4) is the solution to the equations;
Substitute equation 2 into 1;
From 1;
-3x+4y=25
-3x + 4(-3x+4) = 25
-3x -12x + 16 = 25
-15x = 25 - 16
-15x = 9
x = -9/15
x = -3/5
Substitute x = -3/5 into equation 2 to get y;
From 2;
y= -3x+4
y = -3(-3/5)+4
y = 9/5 + 4
Find the LCM
y = (9+20)/5
y = 29/5
Hence the solution to the system of equation is (-3/5, 29/5) hereby falsifying Julie's solution.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The Smiths are sending out a batch of holiday cards. Emily signed of the cards. Then Josh signed of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed? There are cards yet to be signed.
Answer:
You will get 75 cards
Step-by-step explanation:
The answer is 32
Emily signed 2/5 so 75 divided by 5 is 15
15x2 is 30
75-30=45
45 divided by 1/9 is 5
30+5=35
so then 45-5=40
20% of 40 is 8
30+5+8 = 43
75-43=32

TR = 3x + 5, and RA = x + 17. Find the value of x.
Answer: x=6
Step-by-step explanation:
TR=RA since TR and RA are congruent

3x+5-5=x+17-5
3x=x+12
3x-x=x-x+12
2x=12
2x/2=12/2
x=6

The cost to rent a rug cleaner is $25 plus $15 per hour at Floors, Inc. At Rugs R Clean the rug cleaner costs $45 plus $7 per hour. Which inequality can be used to show how many hours you need to rent the rug cleaner so that Floors, Inc.'s charges will be same the charges at Rugs R Clean?
Answer:
25 + 15x < 45 + 7x
Step-by-step explanation:
Given:
Floors, Inc. Fixed charges = $25
Floors, Inc. Variable charges = $15 per hour
R rug clean Fixed charges = $45
R rug Variable charges = $7 per hour
Computation:
Assume number of hour = x
Floors, Inc. total cost = 25 + 15x
R rug total cost = 45 + 7x
So,
25 + 15x < 45 + 7x
What is the exact value of tan(195°)?
Given:
The value is tan(195°).
To find:
The exact value of tan(195°).
Solution:
We have,
[tex]\tan (195^\circ)=\tan (180^\circ+15^\circ)[/tex]
[tex]\tan (195^\circ)=\tan (15^\circ)[/tex] [tex][\because \tan (180^\circ-\theta)=\tan \theta][/tex]
It can be written as
[tex]\tan (195^\circ)=\tan (45^\circ-30^\circ)[/tex]
[tex]\tan (195^\circ)=\dfrac{\tan (45^\circ)-\tan (30^\circ)}{1+\tan (45^\circ)\tan (30^\circ)}[/tex] [tex][\because \tan (A-B)=\dfrac{\tan A-\tan B}{1+\tan A\tan B}][/tex]
[tex]\tan (195^\circ)=\dfrac{1-\dfrac{1}{\sqrt{3}}}{1+(1)(\dfrac{1}{\sqrt{3}})}[/tex]
[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{1+\dfrac{1}{\sqrt{3}}}[/tex]
[tex]\tan (195^\circ)=\dfrac{\dfrac{\sqrt{3}-1}{\sqrt{3}}}{\dfrac{\sqrt{3}+1}{\sqrt{3}}}[/tex]
[tex]\tan (195^\circ)=\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex]
Therefore, the exact value of tan(195°) is [tex]\dfrac{\sqrt{3}-1}{\sqrt{3}+1}[/tex].
