I know the answer, I need to know how to solve
Answer:
k = 9
Step-by-step explanation:
For this, we can factor the top expression to look like the bottom expression.
So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.
18[tex]x^{2}[/tex] 11x
1 and 18 19 - No
2 and 9 11 - Yes
3 and 6 9 - No
So, the numbers are 2 and 9. The expression should now look like this:
[tex]x^{2}[/tex] + 2x + 9x + 18
Now, undistribute the terms.
x(x + 2) + 9(x + 2)
(x+2)(x+9)
This matches up with the bottom expression.
The value of k is 9.

what is the equation of the line that passes through the points (11, - 4) and (13,- 7) in slope-intercept form?
answer choices shown in picture
Answer:
E. None of these
Step-by-step explanation:
Points: (11, -4), (13, -7)
slope = m = (y2 - y1)/(x2 - x1) = (-7 - (-4))/(13 - 11) = (-7 + 4)/2 = -3/2
y - y1 = m(x - x1)
y - (-4) = (-3/2)(x - 11)
y + 4 = (-3/2)x + 33/2
y + 8/2 = (-3/2)x + 33/2
y = (-3/2)x + 25/2
Answer: E. None of these
Step-by-step explanation:
A(11,-4) B(13,-7)
x1 y1 x2 y2
y=mx+c
-4=11m+c -(i) -7=13m+c -(ii)
Subtract equation (ii) from (i)
-7=13m+c
-4=11m+c
+ - -
-3=2m
2m=-3
m=-3/2
put m=-3/2 in equation (ii)
-7=13*(-3/2)+c
c=-7+39/2
c=(-14+39)/2
c=15/2
y=mx+c
y=-3/2x+15/2
y=(-3x+15)/2
2y=-3x+15
2y+3x-15=0
Veronica takes of an hour to write of a page of calligraphy.
How long will it take Veronica to write one page of calligraphy?
Using proportions, it is found that it will take Veronica 4/3 of an hour to write one page of calligraphy.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, it is found that she takes 1/3 of an hour to write 1/4 of a page of calligraphy. How long it takes her to write a page?
The rule of three is:
1/3 hour - 1/4 page
x hours - 1 page
Applying cross multiplication:
[tex]\frac{x}{4} = \frac{1}{3}[/tex]
[tex]x = \frac{4}{3}[/tex]
It will take Veronica 4/3 of an hour to write one page of calligraphy.

The types of problems found on ancient papyri, books, and tablets focuses primarily on problems that relate to daily life. The solution methods for many ancient cultures are generally verbal, with mathematical statements written out in words. Why did most ancient cultures primarily write out their mathematical texts in words?
Answer:
Most ancient societies had symbols to represent numbers, but they did not have symbols to represent operations or unknown quantities. Thus, the problems and solutions to the problems had to be written in word form.

Solve inequality 5-3(4x-5)<32
Answer: x > -1
Step-by-step explanation:
1) Subtract 5 from both sides
-3(4x - 5) < 27
2) Divide both sides by -3 (Remember to change the inequality sign to face the other way, because you have multiplied/divided by a negative number)
4x - 5 > -9
3) Add 5 to both sides
4x > -4
4) Divide by 4 on both sides
x > -1
