B
2x = 20
C С
2(x - 5) = 15
D
2x - 20 = 0
E
43 - 10 = 30
F 15 = 5 – 22
Answer:
Step-by-step explanation:
2x - 5 = 15
Bringing like terms on one side
2x = 15 + 5
2x = 20
Option B is the correct answer
Answer:
b) 2x = 20
c) 2(x - 5) = 15
D) 2x - 20 = 0
Explanation
2x - 5 = 15
2x = 15 + 5
2x = 20
x= 20/2
x= 10
a) 2x = 10
x= 10/2
x= 5 (which is not correct)
b) 2x = 20
x= 20/2
x = 10 (which is correct )
c) 2(x- 5) = 15
2x - 10 = 15.
2x = 15 +10
2x = 20
x = 20/2
x= 10 ( which is correct)
d) 2x - 20 = 0
2x = 20
x= 20/2
x= 10 ( which is correct)

Answer:
eeeeeeeeeeeeeeeeeeeeeeeeeeeee
Step-by-step explanation:
Answer:
m = (change in y) / (change in x) = 8/0: undefined
Step-by-step explanation:
Note that the x-coordinate of both given points is the same: -2. This means that x does not change and also that y changes from -4 to 4. The slope is undefined because division by zero is not defined:
m = (change in y) / (change in x) = 8/0: undefined

Primitive function for:
1. f(x)=4e2x+e−x, sådan att F(0)=2
The primitive function for [tex]f(x) = 4e^{2x} + e^{-x}[/tex] is given by it's indefinite integral.
To calculate it, recall:
[tex]\frac{d}{dx}e^{ax}=ae^{ax}[/tex]
[tex]\int c f(x)dx = c\int f(x)dx[/tex]
Let's begin
[tex]\int 4e^{2x}+e^{-x}dx \\4\int e^{2x}dx+ \int e^{-x}dx\\4\frac{e^{2x}}{2}+\frac{e^{-x}}{-1} + c\\[/tex]
[tex]F(x) = 2e^{2x}-e^{-x} +c[/tex]
To find the costant, we just need to use the fact that [tex]F(0)=2[/tex]
[tex]F(0) = 2 \\4e^{0}+e^{0} + c =2\\5+c =2\\c=-3[/tex]
Therefore,
[tex]\boxed{F(x) = 2e^{2x} - e^{-x} -3 }[/tex]

Sarah’s age (s) is 7 less than 2 times Bill’s age, (b).write an equation
Answer:
S= B x 2 -7 should work
Step-by-step explanation:
Sarahs age is equal to Bills age×2 but 7 less so Sarah= Bill x 2 -7
Sarah’s age is 7 less than 2 times Bill’s age is written as s=2b-7
What is Expression?An expression is combination of variables, numbers and operators.
Given,
Let Sarah's age is denoted by s
Bill’s age is denoted by b
Given that Sarah’s age (s) is 7 less than 2 times Bill’s age, (b
We need to write this sentence as expression.
Sarah’s age (s) is 7 less than means Sarahs age should be subtracted of 7.
2 times Bill’s age
2 times means we have to multiply bills age with 2.
s equal to 2 times b minus seven.
s=2b-7.
Hence, Sarah’s age is 7 less than 2 times Bill’s age is written as s=2b-7

The art teacher buys containers to store 1,314 colored pencils. Each container holds 18 pencils. How many containers does the art teacher need to store all the colored pencils?
Answer:
The art teacher needs 73 containers to store all the colored pencils.
Step-by-step explanation:
1,314 colored pencils ÷ 18 pencils per container = 73 containers total
The number of containers the art teacher need to store all the colored pencils is 73.
Given that, the art teacher buys containers to store 1,314 colored pencils.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Here, each container holds 18 pencils.
Number of containers = Total number of pencils/Number of pencils in each container
= 1314/18
= 73
Therefore, the number of containers the art teacher need to store all the colored pencils is 73.

Factoring trinomials and difference of squares. I need to understand the steps.
Answer:
Factoring the term [tex]3x^2-75[/tex] we get [tex]\mathbf{3(x+5)(x-5)}[/tex]
Step-by-step explanation:
We need to solve the polynomial: [tex]3x^2-75[/tex]
First we see that 3 is common term, so taking 3 as common
[tex]3(x^2-25)[/tex]
We know that 25 = 5x5 = 5²
So, replacing 25 with 5²
[tex]3(x^2-5^2)[/tex]
We know that, [tex]a^2-b^2=(a-b)(a+b)[/tex]
Applying this in our equation: [tex]x^2-5^2=(x+5)(x-5)[/tex]
[tex]3(x+5)(x-5)[/tex]
So, factoring the term [tex]3x^2-75[/tex] we get [tex]\mathbf{3(x+5)(x-5)}[/tex]
