What is 2x+1+7x=-8? Could you show work, please?
Answer:
Step-by-step explanation:
2x + 1 + 7x= -8
~2x + 7x = 9x
9x + 1 = -8
move 1 to the other side
9x = -1 -8
9x = -9
divide
X = -1
Answer:
Step-by-step explanation:
Simplifying
2x + -1 = 7x + -8
Reorder the terms:
-1 + 2x = 7x + -8
Reorder the terms:
-1 + 2x = -8 + 7x
Solving
-1 + 2x = -8 + 7x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7x' to each side of the equation.
-1 + 2x + -7x = -8 + 7x + -7x
Combine like terms: 2x + -7x = -5x
-1 + -5x = -8 + 7x + -7x
Combine like terms: 7x + -7x = 0
-1 + -5x = -8 + 0
-1 + -5x = -8
Add '1' to each side of the equation.
-1 + 1 + -5x = -8 + 1
Combine like terms: -1 + 1 = 0
0 + -5x = -8 + 1
-5x = -8 + 1
Combine like terms: -8 + 1 = -7
-5x = -7
Divide each side by '-5'.
x = 1.4
Simplifying
x = 1.4

what is 11x11 ????????????????????
Answer:
121
Step-by-step explanation:
11 x 11
this is what goes on in my head you don't have to this but this is what i do
10 x 10 = 100
10 x 1 = 10
1 x 10 = 10
1 x 1 = 1
100 + 10 + 10 + 1 = 121
The product of the numbers 11 with 11 is 121.
Given are the numbers 11 and 11.
We have to find the product of these numbers.
This can be found in various ways.
We can study the perfect squares from 1 to 20 to know it fast.
Else you can use normal multiplication.
Or another method is,
Split both 11 as 10 and 1 and then find the product with each.
10 × 10 = 100
Then find 10 with 1.
10 × 1 = 10
Then find 1 with 10.
1 × 10 = 10
Then find 1 with 1.
1 × 1 = 1
Total is 100 + 10 + 10 + 1 = 121
Hence the number is 121.

The parent function f(x) = x^2 is vertically stretched by a scale factor of 2, translated 14 units right, and 6 units up. Which equation below represents the new equation? 1. G(x) = 2(x-14)^2 + 6 2. G(x) = 1/2 (x-14)^2 = 6 3. G(x) = 2(x-14)^2 - 6 4. G(x) = 2(x+14)^2 + 6
Answer:
[tex](1)\; G(x)=2(x-14)^2+6[/tex]
Step-by-step explanation:
Assuming, right and up are positive directions.
The given parent function, [tex]f(x)=x^2[/tex]
Let [tex]f_1(x)[/tex] be the function when the parent function is stretched by a scale factor of 2.
So, [tex]f_1(x)=2f(x)[/tex]
[tex]\Rightarrow f_1(x)=2x^2[/tex]
Let [tex]f_2(x)[/tex] be the function when [tex]f_1(x)[/tex] is translated [tex]14[/tex] units right.
So, [tex]f_2(x)=f_1(x-14)[/tex]
[tex]\Rightarrow f_2(x)=2(x-14)^2[/tex]
Again, let [tex]f_3(x)[/tex] be the function when [tex]f_2(x)[/tex] is translated 4 units up.
So, [tex]f_3(x)=f_2(x)+6[/tex]
[tex]\Rightarrow f_3(x)=2(x-14)^2+6[/tex]
So, the resulting function, [tex]f_3(x)=G(x)=2(x-14)^2+6[/tex].
Hence, option (1) is correct.

Answer:
a total number of games played would be 68
Answer:
In the diagram, 17 represents 25% of the total games. Since 17 times 3 equals 51, you use the first 3 columns to find an answer of 75%.

BOXES Simon will make a box without a top by cutting out corners of equal size from a 22 inch by 15 inch sheet of cardboard and folding up the sides. Which of the following is closest to the greatest possible volume of the box?
a. 330 in3
b. 144 in3
c. 432 in3
d. 1296 in3
Answer:
Volume of box is [tex]432 in^3[/tex]
Step-by-step explanation:
Let x be the side of square corner
Length of box after cutting corners =22-2x
Breadth of box after cutting corners =15-2x
Height =x
Volume of box = (22-2x)(15-2x)x
Volume of box =[tex]4x^3-74x^2+330x[/tex]
Differentiate w.r.t x
[tex]\frac{dV}{dx}=12x^2-148x+330[/tex]
Substitute derivative =0
[tex]12x^2-148x+330=0\\x=\frac{37-\sqrt{379}}{6},\frac{37+\sqrt{379}}{6}\\\frac{d^2V}{dx^2}=24x-148[/tex]
at [tex]x=\frac{37-\sqrt{379}}{6}[/tex]
[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37-\sqrt{379}}{6} )-148=-77.87 < 0[/tex] hence maximum
at [tex]x=\frac{37+\sqrt{379}}{6}[/tex]
[tex]\frac{d^2V}{dx^2}=24x-148=24(\frac{37+\sqrt{379}}{6} )-148=77.87>0[/tex] hence minimum
So,Volume of box =[tex]4x^3-74x^2+330x=4(\frac{37-\sqrt{379}}{6} )^3-74(\frac{37-\sqrt{379}}{6} )^2+330(\frac{37-\sqrt{379}}{6} )=432.23 in^3[/tex]
Hence Volume of box is [tex]432 in^3[/tex]

On Monday, Sarah has to meet her friend at the park after school The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
house?
Answer:
8x + 4 - z
Step-by-step explanation:
Given the following :
The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
Distance from house to school = 2x + 5
Distance from school to park = z
Total distance covered = 10x + 9
Distance from park to house =?
Total distance = (distance from house to school + distance from school to park + distance from park to house)
Let p = distance from park to house
10x + 9 = (2x + 5 + z + p)
10x + 9 - 2x - 5 - z = p
8x + 4 - z

How to solve (x-10)(x + 10)
Answer:
x² - 100
Step-by-step explanation:
Use the FOIL method. The FOIL method is the way in which you multiply the terms:
FOIL stands for First, Outside, Inside, Last. Multiply:
First:
x * x = x²
Outside:
x * 10 = 10x
Inside:
-10 * x = -10x
Last:
-10 * 10 = -100
Combine like terms:
x² + 10x - 10x - 100
x² + (10x - 10x) - 100
x² - 100
x² - 100 is your answer.

Answer:
d. z = -48
Step-by-step explanation:
When j ║ k, corresponding angles are congruent, so ...
x = 4z +3y
57 = y + z
and the same-side interior angles are supplementary:
57 +x = 180 ⇒ x = 123
__
This lets us write two equations in y and z:
3y +4z = 123
y +z = 57
Using the second equation to write an expression for y, we have ...
y = 57 -z
Substituting this into the first equation gives ...
3(57 -z) +4z = 123
z +171 = 123
z = -48 . . . . . . . subtract 171
The value of z that makes j║k is -48.
___
The corresponding value of y is 105.
