An unknown polynomial is added to the expression -3x^3+2x-5 and the resulting sum is 4x^3+7x^2-3. what is the unknown polynomial?
Answers
Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8

What is the measure of angle 3?
1
Answers
Answer:
129
Step-by-step explanation:
Every angle would be similar to each other with having only TWO different degrees...
Each line ( <----------------------> ) equals 180 (never 360, b/c that would be a circle)
Now with you only having 51 as a degree, you need to do 180-51 which gives you 129, with that given, this tells you number 1 and 3 is both 129, and angle 2 is 51.

What factors of -27 have the sum of 6
Answers
Answer:
9 and -3
Step-by-step explanation:
9 and -3 are both factors of -27 since they can be multiply each other to get -27. Also, they both add up to 6.
The factors of -27 that sum up to 6 are 9 and -3
How to determine the factors of -27 that sum up to 6From the question, we have the following parameters that can be used in our computation:
Factors = -27
Sum = 6
Let the numbers be x and y
So, we have
xy = -27
x + y = 6
Let x be 9 and y be 3
So, we have
9 * -3 = -27
9 - 3 = 6
Hence, the numbers are 9 and -3

Which point would be on the inverse of this function?
Group of answer choices
(-10, -7)
(-6, -3)
(-2, -5)
(9, 6)
Answers
Point (9, 6) would be on the inverse of this function so option (D) will be correct.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
Given the sets of coordinates of a function.
An inverse function is the reciprocal of a function and the coordinate of the inverse function is interchanged with the original function.
For example, if (x,y) is the coordinate of the function then (y,x) will be the coordinate of the inverse of the function.
Since option (D) (9, 6) is the interchange of (6,9) so it will be the inverse of a function.
Hence "Point (9, 6) would be on the inverse of this function".

Unit 1: geometry basics homework 2: segment addition postulate I need the answers for this worksheet please and thank you
Answers
The answers to the segment addition problems are :
LN = 37MN = 23 EF = 58The required worksheet is attached below :
A segment is simply the shortest distance between two points, For a line segment, it is the line which connects two points.
Given that :
LM = 22 ; MN = 15
The segment LN is defined as :
LN = LM + MN
LN = 22 + 15
LN = 37
2.)
LN = 54
LN = 54 LM = 31
The line segment, LN equals :
LN = LM + MN
54 = 31 + MN
MN = 54 - 31
MN = 23
3.)
DF = 9x - 39
DE = 47
EF = 3x + 10
The line segment, DF equals ;
DF = DE + EF
9x - 39 = 47 + (3x + 10)
9x - 39 = 47 + 3x + 10
9x - 3x = 47 + 10 + 39
6x = 96
x = 96 / 6
x = 16
Hence,
EF = 3x + 10
EF = 3(16) + 10
EF = 48 + 10
EF = 58

the bottom one:
the line that cut the traingle, made each angle is 90°
10/sin90° = 5/sin?
sin? = 5sin90°/10 = 1/2
the angle is sin^-1 (1/2) = 30° ⇒
10/sin90° = ?/sin60°
? = 10sin60°/sin90° = 5√3 ⇒
12/sin90° = 5√3/sin?
sin? = 5√3 sin90°/12 = 5√3 /12
? ≈46°
180 - (46+90) = 44° ⇒
x/sin44° = 12/sin90°
x = 12sin44°/sin90° = 8.3

Point S is on line segment RT. Given ST = 3x-8, RT = 4x, and RS = 4x-7, determine the numerical length of RT.
Answers
Answer:
20.
Step-by-step explanation:
1) according to the condition RT=ST+RS;
2) if RT=4x, ST=3x-8; RS=4x-7, then it is possible to re-write the equation as:
4x=(3x-8)+(4x-7);
3) if to solve this equation, then:
4x=7x-15; ⇔ 3x=15; ⇔ x=5.
4) if x=5, then the length of RT is:
RT=4x=20.

x < 2 or (-∞, 2)
Step-by-step explanation:
(f -g)(x) = (x -3) -(-0.5x) = 1.5x -3
We want to find (f -g)(x) < 0, so we have ...
1.5x -3 < 0
1.5x < 3 . . . . . . . add 3
x < 2 . . . . . . . . . .divide by 1.5
The function (f -g)(x) is negative on the interval x < 2.

Answers

Answer:
C. (x -1)/(x +7)
Step-by-step explanation:
The factor (x +1) in the numerator cancels the same factor in the denominator, leaving the ratio (x -1)/(x +7). This matches choice C.
_____
Additional comment
Even though (x+1)/(x+1) = 1 and can be removed from the expression, the fact that it is undefined at x=-1 means the reduced ratio (x-1)/(x+7) is only a valid representation of the original ratio when x≠-1. The factor (x+1) may be gone, but the domain restriction associated with it remains.

32km/hr = ______mi/da 1 day = 24 hrs, 1m=3.28ft, 1km=1000m,1mi=5280ft
32km/hr x 24hr/day x 1000m/1km x 3.28ft/1m x 1mi/5280ft = 477.09mi/da
If student can use 1km = 0.62mi, some steps can be skipped.
