Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?
Answers
Step-by-step explanation:
f(7) = 34
7² -5(7) +k = 34
49-35+k =34
14+k = 34
k = 34-14
k = 20
Step-by-step explanation:
f(7) = 34
7² -5(7) +k = 34
49-35+k =34
14+k =34
k = 34-14
k = 20

What is the completely factored form of this polynomial?
18x3 – 120x2 - 42x
Write the greatest common factor (GCF) first, and write all factors in standard form.
Answers
Answer:
6x(3x + 1)(x - 7)
Step-by-step explanation:
First look for the greatest common factor of the 3 terms.
The GCF is 6x, so
18x^3 – 120x^2 – 42x
= 6x(3x^2 - 20x - 7)
Now we look to factor the quadratic expression in the parentheses:
The first and last coefficients are multiplied
3 * -7 = -21.
We look for 2 numbers whose product is -21 and whose sum is -20:
They are -21 and + 1 , so we write:
6x(3x^2 - 21x + 1x - 7)
= 6x [ (3x(x - 7) + 1(x - 7)] Note that x - 7 is common, so:
= 6x(3x + 1)(x - 7) Answer

if you wrote the number 0.0009763 as a single digit times a power of ten, would the exponent be positive or negative? explain.
Answers
Answer:
10^n means to multiply by 10
10^-n means to divide by 10 or multiply by 1 / 10
So .0009763 means 9.763 / 10000 = 9.763 * 10-4
can also write as 9.763E-4
If multiplying then the power of 10 would have to be negative
What value of x makes the equation -5x - (-7 - 4x) = -2(3x - 4) tru
Answers
Answer: 1/10 or 0.1
Step-by-step explanation:
-(-7 - 4x) = -2(3x - 4)
7 + 4x = -6x + 8
* subtract 7 from both sides
4x = -6x + 1
* Add 6x to both sides
10 x = 1
* Divide both sides by 10
x = 1/10 or 0.10
This step makes sure that you know to distribute the negative.
-5x + [-(-7-4x)] = -2(3x-4)
Continue to simplify. Start by distributing across the parentheses.
-5x+(7+4x)= -6x+8
-5x+4x+7= -6x+8
-x+7=-6x+8
Once you can’t simplify either side any more, you try and isolate the variable onto one side.
-x+7=-6x+8
+x. +x
________
7=-5x+8
Then isolate the constants into one side.
7=-5x+8
-8. -8
______
-1=-5x
Then make sure you have the variable being multiplied only once.
-1= -5x
—. —
-5. -5
0.2=x
And then move your variable to the left.
x=0.2
The value of x that makes the equation true is 0.2

Thomas and Silvia are brother and sister. Thomas is 12 years older than Silvia and their combined ages are 44. How old are Thomas and Silvia?
show work please
Answers
so in conclusion, thomas is 22 and silvia is 10
but that answer is wrong.
44 minus 12 is 32, now divide 32 by 2 and you get 16.
so this would mean that thomas is 32, and silvia is 16, but that doesn’t add up either.

Given m∠LMN=145 what is ∠XMN?
Answers
Answer:
(4x+5)°+(6x-10)°=145°
4x+6x+5-10=145°
10x-5=145°
10x=145+5
10x=150°
x=15
(6x-10)°=(6×15-10)°
=80°
The value of ∠XMN = 80.
What is angle?An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint.
The value of total ∠LMN = 145.
∠LMN = ∠LMX +∠XMN
145 = (4x + 5) + (6x - 10)
145 = 4x + 5 + 6x - 10
145 = 10x -5
10x = 150
x = 15
Substitute the value of x in ∠XMN = (6x - 10)
∠XMN = 6×15 - 10
= 90 - 10
∠XMN = 80
Therefore, the value of the angle ∠XMN = 80.

Answers
1. At the end of the 5th week he would have saved a total of $700
2. The amount of flour he would have at the closing time on 17th of the month will be 16kg
1.
Azad amount = $500
He wants to go on a holiday but he lacks sufficient money. This means the $500 in his possession is not enough.
He decided to save $40 dollars per week for a number of weeks to make up the deposits.
let
w = number of weeks
Therefore, his saving for any number of weeks will be
40wThe amount he would have saved for 5 weeks will be
40×5=$200
The total amount in his possession at the end of the fifth week will be 200 + 500 = $700
2.
The baker has 400 kg of flour. The first day of the month he didn't use any flour. This means on the first day of that month the flour was still 400 kg. The amount he has on the 17th day of the month can be calculated below.
The 17th day simply implies he used the flour for 16 days, the first day of the month he didn't use anything. He uses 24 kg for each day. Therefore the amount he uses for 16 days will be
16×24=384 kgThe amount he has at the closing time of 17 days of the month will be

point Find the length of segment CD with C(2,3) and D (-3, 15
Answers
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment

3x+10=43 what is x to the what are the steps to equal X to the math equation
Answers
Answer:
x = 11
Step-by-step explanation:
When solving for x, you want to get the variable by itself on one side of the equation. The first step is to subtract 10 from both sides. 43-10=33. So, it should look like:
3x = 33
Divide both sides of the equation by 3 to get x alone. 33/3 equals 11. So x =11. Hope this helped and lmk if you have more questions!!

It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.

2nd answer, and 5 hours
Step-by-step explanation:
Section 1
The answer is the 2nd one down. The tickets are selling at a rate of
floor tickets: 100/h; stand tickets: 75/h
Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.
Section 2
There are only 375 stand tickets left to sell.
Every 2 hours 150 are sold or you can also say 75 per hour.
If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.
375/75 = 5 hours
