The equation represents the pages after x nights.
Wren:
12 + 4x
Jenni:
4 + 5x
After 8 nights Wren and Jenni will be on the samepage of the book.
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equalsign.
We have,
Wren and Jenni are reading the same book.
Wren is on page 12 and reads 4 pages every night.
This can be written as an equation.
12 + 4x _____(1)
x = number of nights.
Jenni is on page 4 and reads 5 pages every night.
This can be written as an equation.
4 + 5x _______(2)
x = number of nights.
The number of nights after which both of them will be on the samepage.
From (1) and (2) we get,
12 + 4x = 4 + 5x
12 - 4 = 5x - 4x
8 = x
x = 8
Thus,
The equation represents the pages after x nights.
Wren:
12 + 4x
Jenni:
4 + 5x
After 8 nights Wren and Jenni will be on the samepage of the book.

Equation of parabola:
Step-by-step explanation:
A parabola with vertex (0,0), that opens to the right.
The general equation of parabola open right whose vertex (0,0)
Focal width : Two points opposite to the the focus on parabola.
Distance between these two points is called focal width i,e 4p
Focal width = 8
So, 4p=8
p=2
Focus: (2,0)
Equation of parabola:
Answer:
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y

Answer:
D) (-1,1),(-1,5),(-7,1)
Step-by-step explanation:
The vertices of the triangle shown in the coordinate plane are: (-1,1), (-1,3), (-4,1)
The legs are in the ratio:2 : 3
For triangle with vertices A) (-1,1),(-1,4),(-6,1) ,
The legs are in the ratio: 3:5
For triangle with vertices:
B) (-1,1),(-1,5),(-6,1)
The legs are in the ratio:
4:5
For the triangle with vertices:
C) (-1,1),(-1,4),(-7,1)
The legs are in the ratio:
3:6=1:2
For triangle with vertices:
D) (-1,1),(-1,5),(-7,1)
The legs are in the ratio:
4:6=2:3
Therefore the correct answer is D.
Because similar triangles have their corresponding sides in the same proportion.

so the babysitting job pays 4 dollers pay per hour
she works x hours
therefor the babysitting pay is 4 times x or 4x
the library job pays 7 dollars an hour
she works y hurs
therefor the library pay is 7 times y or 7y
so total pay is babysitting pay plus library pay or
4x+7y=total pay
x+y=total hours
she wants to work no more than 16 hour s aweek, means that she can work max 16 hours or
total hours<16
subsitute
x+y<16
and she wants to earn at least 80 dolars
so more than or equal to 80 dolllars
total pay >80
subsitue
4x+7y>80
so the inequalities we have are
x+y<16 and
4x+7y>80
solve for y since we want to do that
multiply the first equatl by -4
remember tha tmultipy by negative means flip sign from < to > so
-4x-4y>-64
now add to the second equation
-4x-4y>-64
4x+7y>80 +
0x+3y>16
3y>16
divide by 3
y>16/3
16/3=5 and 1/3
so she has to work more than 5 and 1/3 hours per week
basically, she will earn at least 80 dollars a week if she works at least 5 and 1/3 hours at the library and works for 16 hours total (library+babysitting)
what you should do is find the graph of the lines
x+y<16 and 4x+7y>80 and find where they intersect
the inequaltiy is 4x+7y>80 and x+y<16
