Elliot has a total of 26 books. He has 12 more fiction books than nonfiction books. Let x represent the number of fiction books and y represent the number of nonfiction books.
The system of equations models the total costs for each.
x + y = 26
x – y = 12
Elliot added the two equations and the result was
2x = 38.
Solve the equation. How many of each type of book does Elliot have?
fiction books
nonfiction books
Answer:
Step-by-step explanation:
As 2x -38
x-19
now.
putting value in eq 1
X-Y-12
thus,19-Y =12
Y=7
Fiction books=X=19

What is the volume?
cubic inches
What is the surface area?
square inches
Volume of a cube = l³
= (11 in)³

Surface area of cube = 6a²
= 6 (11 in)²
= 726 in²
The Empire State Building has 102 stories. The building was created at a rate of 4 1/2 stories per week. How many weeks did it take to complete the building?
Answer:
22.6
Step-by-step explanation:

Jerry's mother is 36 years old and she is eleven less than four times Jerry's age.how old is Jerry?
Answer:
Jerry is 11.75 years
Step-by-step explanation:
Let us first set up an equation
Let jerry's age be x
4x - 11 = 36 (equation set)
Now we need to slove the equation and find the value of x that is Jerry's age
4x - 11 = 36
Transpose
4x = 36 + 11
4x = 47
x = 47 ÷ 4
x = 11.75 years
Jerry is 11.75 years

Write an equation for a parabola with x-intercepts (-4,0) and (2,0) which passes through the point (1,-10).
Answer:
y=2x^2+4x−16
Step-by-step explanation:
Assume that the equation of the parabola is y=ax2+bx+c.
Since the parabola passes through the point (−4,0), then 0=16a−4b+c.
Since the parabola passes through the point (2,0), then 0=4a+2b+c.
Since the parabola passes through the point (1,−10), then −10=a+b+c. Thus, we have obtained the following system:
{16a−4b+c=0; 4a+2b+c=0; a+b+c=−10Solving it, we get that a=2, b=4, c=−16. Thus, the equation of the parabola is y=2x^2+4x−16.
The equation of a parabola is y = -x² + x + 4 with x-intercepts at (-4,0) and (2,0) that passes through the point (1,-10).
What is the equation for a parabola?A parabola can be represented by the equation:
y = ax² + bx + c
To find the equation of a parabola that has x-intercepts at (-4,0) and (2,0), we can set y equal to 0 and solve for x to find the x-intercepts:
0 = a(-4)² + b(-4) + c
0 = a(2)² + b(2) + c
Solving these equations for a and c gives us:
c = b(-4)
c = -2b
The parabola passes through the point (1,-10), we can substitute the values of x and y into the equation to solve for b:
-10 = a(1)² + b(1) + (-2b)
-10 = a + b - 2b
-10 = a - b
Substituting c = b(-4) into the equation gives us:
y = a x² + b x + b(-4)
Substituting a = -b and solving for b gives us:
y = (-b) x² + b x + b(-4)
y = -b(x² - x - 4)
Since the x-intercepts are at (-4,0) and (2,0), the coefficient of x², which is -b, must be positive. Therefore, we can set b = 1 to get the equation of the parabola:
y = -(1)(x² - x - 4)
y = -x² + x + 4
Thus, the equation of a parabola is y = -x² + x + 4.

Christine can type 63 words in 9 minutes. What is her rate in words per minute?
Answer:
7 words per minute
Step-by-step explanation:
63 words = 9 mins
9 mins = 63 words
1 min = 63 words/9
1 min = 7
She can type 7 words per minute
-Chetan K
Answer:
7 words per minute
Step-by-step explanation:
1. To find the unit rate (words per minutes), let's set up two ratios:
63:9 = x:1 or 63/9 = x/12. Now, let's solve for x to find how many words she can type per minute.
Step 1: Cross-multiply.
[tex]9 * x = 63 * 1[/tex] [tex]9x = 63[/tex]Step 2: Divide both sides by 9.
[tex]\frac{9x}{9} = \frac{63}{9}[/tex] [tex]x = 7[/tex]Therefore, Christine can type 7 words per minute.
Geometry please help ASAP
Answer:
D) 22
Step-by-step explanation:
B is the midpoint. The midpoint is the point in a line that breaks the line into two equal segments. With that info, we know that BC = AC.
So that means:
3x - 14 = x + 10
Now solve this equation.
3x - 14 = x + 10
+14. +14
3x = x + 24
-x
2x = 24
/2. /2
X = 12.
Now we know the value of x, insert the value into x + 10.
12 + 10 = 22
The answer is 22
Answer:
B) 12
Step-by-step explanation:
Because,
3x - 14 = x + 10
3x - x = 10 + 14
2x = 24
x = 12

Write the equation of the line that passes through the points (2,-2)( and (−9,9). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
using the formula( y2-y1/x2-x1 = m)
m= slope
9 - (-2)/-9 -2 =m
11/ -11 = m
m= -1( slope)
since m is also = y- y1/ x-x1
y - (-2)/ x- 2 = -1= y +2 / x -2 = -1 (cross multipy)
-1 (x -2) = y +2
-x +2 = y + 2
-x -y = 2 -2
-x - y = 0(multiply both sides by -1)
x + y = 0
