There is one possible way:
(4x² - 47x + 141)/(x² + 13x + 40) = (4x² + 4*13x + 4*40 - 47x - 52x - 160 + 141)/(x² + 13x + 40) =4 - (99x + 19)/(x² + 13x + 40)No further simplification
Answer:
basic polynomial division.put 4 in quotient,subtract with the dividend the multiplicative integer, then what in the remainder. stays a remainder.partial fraction is the sum of polynomial, decomposition, with a simple denominator.answer: [tex]4+\frac{-99x-19}{x^2+13x+40}[/tex]Solve for x using the given information. Explain your steps.
6x + ( 3x - 9) = 90°( being complementary angles )
6x+3x -9 = 90°
9x = 90° + 9
x = 99 / 9
x = 11
The points (-12, 6) and (-4, r) lie on a line with slope - 1/2
Find the missing coordinate r.
Answer:
r = 2
Step-by-step explanation:
Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
Substitute the known values for their respective variables and solve for the missing coordinate, r.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\ -\frac{1}{2}=\frac{6-r}{-12-(-4)}\\\\-\frac{1}{2}=\frac{6-r}{-8}\\\\ -8(-\frac{1}{2})=(\frac{6-r}{-8})-8\\\\ 4=6-r\\\\4-6=6-r-6\\\\-2=-r\\\\\frac{-2}{-1}=\frac{-r}{-1}\\\\ 2=r[/tex]
(4x+7) ° is congruent to [5(x-4)] °
What is the value of x?
Answer:
x=17
Step-by-step explanation:
1) 4x +7 = 5(x-4) Congruent angles
2) 4x + 7 = 5x -10 Distributive Property
3) Simplify
4x + 7 = 5x - 10
-4x -4x
7 = x - 10
+10 +10
x = 17

Lesson 19 Practice
Rewrite the product as a sum or difference of two terms: 2(x + y)
Hey there!
2(x + y)
DISTRIBUTE 2 WITHIN the PARENTHESES
= 2(x) + 2(y)
= 2x + 2y
Therefore, your answer is: 2x + 2y
Basically, 2 (the first one) is your coefficient, x & y are your variables, and 2 (the second one) is your constant. Whereas, your addition symbol (the sum or +) is your operator.
Good luck on your assignment & enjoy your day!

For what value of y does 125 = (StartFraction 1 Over 25 EndFraction) Superscript y minus 1? Negative five-halves –2 –1 Negative one-half.
Answer:
D. -1/2
Step-by-step explanation:
First to rewrite the equation in numbers
[tex]125=\frac{1}{25}^{y-1}[/tex]
First, we need to find what exponent would get 1/25 to 125.
[tex]\frac{1}{25}^{y}=125[/tex]
Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.
Answer:
Keep it simple: D or -1/2

How do I find the slope of the line?
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Step-by-step explanation:
yeah
Answer:
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

Jose and his 3 friends equally shared $20 at Taco Bell last night.
Use the model below to determine x, the amount each child
spent at Taco Bell.
Answer:
x = 5
Step-by-step explanation:
The model tells you ...
4x = 20
x = 20/4 = 5 . . . . . divide both sides by 4
Each child spent $5 at Taco Bell.
is x =4 a solution of the equation
13=2x + 4?
A.yes
B.no
No, it is not. If you plug 4 into the equation in the place of x, you get 13=2(4)+4
13=8+4
13=12
It equals 12, not 13.
Answer:
No
Step-by-step explanation:
Because If You Do 2 x 4 you get 8 and 8 + 4 = 12 and not 13 so the answer is 4.5 because 4.5 x 2 = 9 and 9 + 4 = 13

Can anyone please help me with this? I’d appreciate it a lot!
Answer:
(−2, −3)
Step-by-step explanation:
Let's solve your system by substitution.
x−9y=25;6x−5y=3
Step: Solvex−9y=25for x:
x−9y=25
x−9y+9y=25+9y(Add 9y to both sides)
x=9y+25
Step: Substitute9y+25forxin6x−5y=3:
6x−5y=3
6(9y+25)−5y=3
49y+150=3(Simplify both sides of the equation)
49y+150+−150=3+−150(Add -150 to both sides)
49y=−147
49y
49
=
−147
49
(Divide both sides by 49)
y=−3
Step: Substitute−3foryinx=9y+25:
x=9y+25
x=(9)(−3)+25
x=−2(Simplify both sides of the equation)
Therefore answer:
x=−2 and y=−3 which is (-2, -3)

Answer:
18480 ft
Step-by-step explanation:
Note that 1 mile = 5280 feet. We can use this information to set up a unit converter:

Miles cancels out on the bottom giving us...
[tex]3.5*5280ft=18480ft[/tex]
if the radius of a circle is increased by 50 perent what will be the percent increase in the circumfrence
Answer:
50%
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
In this case, the radius and the circumference are directly proportional meaning that if the radius increases by 50%, the circumference will also increase by 50%.
Let's use some examples to prove this:
Radius : 2
Increase by 50% : 2*50%=2*(50/100)=2(1/2)=1 --> 1+2 = 3
[tex]C=2\pi r=2\pi 3=6\rightarrow 50 \ percent\ increase\ from\ 4\\C=2\pi r=2\pi 2=4[/tex]
Radius : 4
Increase by 50% : 4*50%=4*(50/100)=4(1/2)=2 --> 2+4 = 6
[tex]C=2\pi r=2\pi 6=12\pi\rightarrow50\ percent\ increase\ from\ 8\\C=2\pi r=2\pi 4=8\pi[/tex]
In both cases, when we increased the radius by 50%, the circumference also increased by 50%, proving our previous statement correct.
Therefore, when the radius of a circle is increased by 50%, the circumference will also increase by 50%

f(x) = -9x + 7 find f(3) HELPPP
The given function is ,
→ f(x) = -9x + 7 .
And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,
→ f(3) = -9*3 +7
→ f(3) = -27+7
→ f(3) = -20
Hence the required answer is-20 .

[tex]\underline{\textsf{Example;}}[/tex]
[tex]\tt \frac{1}{3} = \frac{2}{x}[/tex]
[tex]\textsf{We are asked to find x in the given proportion. We should use the cross}[/tex]
