Answer:
(x + 3)(x² – 3x + 7)
Step-by-step explanation:
To express x³ + 2x + 21 in the form of (x + 3)(px² + qx + r),
we need to divide (x³ + 2x + 21) by
(x + 3), since (x + 3) is a factor of
(x³ + 2x + 21)
See attached photo on how to divide (x³ + 2x + 21) by (x + 3).
From the attached photo,
(x³ + 2x + 21)/ (x + 3) = x² – 3x + 7
Therefore,
x³ + 2x + 21 => (x + 3)(px² + qx + r)
x³ + 2x + 21 => (x + 3)(x² – 3x + 7)

For what value of k does the line represented by the equation 1-kx = -3y contain the point (4,-3)?
Answer:
k = -2
Step-by-step explanation:
Given equation
1-kx = -3y
point on this line = (4,-3)
If point lies on the given line, then if we plug in the value (4,-3), then it will satisfy the equation
1-kx = -3y
using x = 4 and y = -3
1-k*4 = -3*-3
1 - 4k = 9
=> -4k = 9 -1 = 8
=> k = 8/-4 = -2
Thus, value of k is -2

A. (1,3)
B. (0,1)
O C. (0,3)
D. (1.4)
Answer:
D: (1, 4)
Step-by-step explanation:
You can either solve by substitution or elimination. If you are timed, the fastest way is to guess and check (plug-in the answer choices)
I will be using substitution to solve this:
Step 1: Since you have y already, you can set them equal to each other
x+3 = 3x+1
3 = 2x +1
2 = 2x
x = 1
Step 2: Now you have x, plug x into one of the original equations. In this case, I will use the first one
y = 1 + 3
y = 4
Step 3: Now write your answer as a coordinate plane point
x = 1, y = 4

Give your answer to the nearest hundredth.
A = [?] cm2
Answer:
See Explanation Below
Step-by-step explanation:
Your question isn't clear; However, I'll solve in two ways
1. Diameter = 14 cm
2. Radius = 14 cm
When Diameter = 14 cm
Given
[tex]Area = \pi r^2[/tex]
[tex]Diameter = 14cm[/tex]
Required
Calculate the area of the circle
First, the radius has to be solved;
[tex]Radius = \frac{1}{2} Diameter[/tex]
[tex]Radius = \frac{1}{2} * 14cm[/tex]
[tex]Radius = 7cm[/tex]
Using the given formula;
The area is as follows
[tex]Area = \pi r^2[/tex]
[tex]Area = 3.14 * 7^2[/tex]
[tex]Area = 3.14 * 49[/tex]
[tex]Area = 153.86cm^2[/tex]
When Radius = 14 cm
Given
[tex]Area = \pi r^2[/tex]
[tex]Radius = 14cm[/tex]
Required
Calculate the area of the circle
Using the given formula;
The area is as follows
[tex]Area = \pi r^2[/tex]
[tex]Area = 3.14 * 14^2[/tex]
[tex]Area = 3.14 * 196[/tex]
[tex]Area = 615.44cm^2[/tex]
ASAPPP What is the slope of the line represented by the equation y
3?
-3
4
o
O
The slope of the line represented by this equation is 4/5.
We know this because this line is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept. Thus, we can conclude that the slope is 4/5, which means that for every 4 units the line moves up, it also moves 5 units over (because slope is defined as rise/run).
This equation is in slope-intercept form, or
y = mx + b where m is the slope and b is the y-intercept. The number in the m position in our equation is 4/5, so the slope is 4/5

please mark me brainliest :)
I really need help yall lives depend on the right answer will get marked as brainliest !!!!!!! Drag the tiles to the boxes to form correct pairs. Not all tiles will be used. Match the fractions with equivalent percentages.
Answer:
60% = [tex]\frac{3}{5}[/tex]
75% = [tex]\frac{3}{4}[/tex]
84% = [tex]\frac{21}{25}[/tex]
65% = [tex]\frac{13}{20}[/tex]
Step-by-step explanation:
60% = [tex]\frac{3}{5}[/tex] because 3 ÷ 5 = 0.6
75% = [tex]\frac{3}{4}[/tex] because 3 ÷ 4 = 0.75
84% = [tex]\frac{21}{25}[/tex] because 21 ÷ 25 = 0.84
65% = [tex]\frac{13}{20}[/tex] because 13 ÷ 20 = 0.65
Hey there! :)
Answer:
60% <--> 3/5
75% <--> 3/4
65% <--> 13/20
84% <--> 21/25
Step-by-step explanation:
When comparing fractions to percentages, make each fraction out of 100:
[tex]\frac{3}{5} = \frac{60}{100}[/tex] = 60%
[tex]\frac{3}{4} = \frac{75}{100}[/tex] = 75%
[tex]\frac{13}{20} = \frac{65}{100}[/tex] = 65%
[tex]\frac{21}{25} = \frac{84}{100}[/tex] = 84%

Step-by-step explanation:
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
x = 5.5 to the nearest tenth.
Step-by-step explanation:
Here we have a right triangle with one angle (65 degrees) given. Side x is the "side adjacent to the angle" and is to be found. The hypotenuse is 13.
The cosine function makes use of these three knowns: the angle, the hypotenuse and the adjacent side. Thus:
cos 65 degrees = adj / hyp = x / 13, or
x = 13 cos 65
Evaluating this on a calculator, we get x = 5.49, or x = 5.5 to the nearest tenth.

Find all possible values of the digits Y, E, A, R if YYYY - EEE + AA - R = 1234, and different letters represent different digits.
Answer:
Y=2, E=9, A=1, R=0
Step-by-step explanation:
YYYY starts from thousand
EEE starts from hundred
AA starts from tens
R is a units
So we can have
1000Y+100Y+10Y+Y-100E-10E-E+10A+A-R=1234
1111Y - 111E + 11A - R=1234
Y cannot be greater than 2 and it can't be 1 either because
if Y is 1, we will have a total of one thousand one hundred and eleven (1111) which is less than one thousand two hundred and thirty-four (1234) as from the answer in the question
So, it is safe to say Y=2 in order to have two thousand two hundred and twenty-two(2222)
This means that Y must be 2:
2222-111E+11A-R=1234
In this case, E would have to be 9 to make it possible for this to have a solution, by bringing it down to 1223.
YYYY-EEE
2222-999=1223
1223+11A-R=1234
1223+11=1234
This means that A must be 1 and that R must be 0.
2222
- 999
+11
-0
=1234

X-3x+4=3-9 what is x?
Answer:
x=5
Step-by-step explanation:
x-3x can be simplied to -2x and 3-9 can be simplied to -6
-2x+4=-6
Substract 4 from both sides
-2x=-10
Divide both sides by -2
x=5
Answer:
[tex]x=5[/tex]
Step-by-step explanation:
[tex]x-3x+4=3-9\\x-3x+4=-6\\-2x+4=-6[/tex]
Subtract 4 from both sides
[tex]-2x+4-4=-6-4\\-2x=-10[/tex]
Multiply both sides by -1
[tex]2x=10[/tex]
Divide both sides by 2
[tex]x=5[/tex]

Jade measured the height of an art frame as 5.23 feet, but the actual height was 6 feet. What is the percent of error in Jade’s measurement?
12.83%
13.55%
14.72%
15.55%
Answer: A
Step-by-step explanation:
Percentage error is error divided by actual value multiply by 100. That is,
%error = error/actual value × 100
If Jade measured the height of an art frame as 5.23 feet, where the actual height was 6 feet. Then,
Error = 6 - 5.23 = 0.77
Substitute error = 0.77 and the actual value = 6 into the formula
%error = 0.77/6 × 100
%error = 12.83 %
Therefore, the percent of error in Jade’s measurement is 12.83%
Answer:
12.83
Step-by-step explanation:
took the test got a 100% percent surprisingly ummmm anywaysss....
SOMEONE PLEASE HELP ME ASAP PLEASE!!!
Answer:
243,729
Step-by-step explanation:
You just need to multiply each number by 3.
I hope this help you :)
Answer:
243, 729
Explanation:
To solve this problem we must first understand what the pattern is in the sequence. Once we understand the pattern, we can then apply it to the final known term to find the next two terms.
Take a look at the sequence given:
1, 3, 9, 27, 81,...
Let's start by figuring out how they got the second term in the sequence. To do that, identify what basic operation and number must be applied. This will reveal the pattern.
1 - first term
3 - second term
1 ? ? = 3
1 × 3 = 3
So, this means the sequence multiplied three to get the next term. Therefore, the pattern should be 'multiply three' to get the next term. Just to be sure the pattern we found is correct, apply it to the given sequence.
1, 3, 9, 27, 81,...
1 × 3 = 3
3 × 3 = 9
9 × 3 = 27
27 × 3 = 81
So, since 'multiply three' every time gives us the next term, the pattern is correct.
Finally, let's continue the pattern to find the next two terms.
81 × 3 = 243
243 × 3 = 729
Therefore, the next two terms in the sequence are 243, 729.
Which of the following pairs of functions are inverses of each other? A)f(x)=2x-9 and g(x)=(x+9)/(2) B)f(x)=(2)/(x)-6 and g(x)=(x+6)/(2) C)f(x)=(x)/(3)+4 and g(x)=3x-4 D)(x)=5+\root(3)(x) and g(x)=5-x^(3)
Answer:
A)f(x)=2x-9 and g(x)=(x+9)/(2)
Step-by-step explanation:
f(g(x)) =x for inverses
A)f(x)=2x-9 and g(x)=(x+9)/(2)
2(x+9)/2) -9 = Canceling the 2 x+9 -9 = x inverse
B)f(x)=(2)/(x)-6 and g(x)=(x+6)/(2)
2/(x+6)/2 ) -6 =4/(x+6) - 6 This will not give me x
C)f(x)=(x)/(3)+4 and g(x)=3x-4
(3x+4)/3 -4 = x + 4/3 -4 This will not give me x
D)(x)=5+\root(3)(x) and g(x)=5-x^(3)
5 + cuberoot ( 5-x^3) This will not give me x back
Answer:
2x-9 is the inverse of x+9/2

How do functions connect elements of their domain to elements of their range?
Answer:
All of the values that can go into a relation or function (input) are called the domain. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
Answer:
Step-by-step explanation:
Each element of the domain connects to no more than ONE element of the range. More than one such connection indicates a relation, not a function.
