Please can someone help? As i'm not confident this is right for factorising 4b^2 + 8b + 3
Answers
Answer:
your answer is correct
Step-by-step explanation:
4b² + 8b + 3
Consider the factors of the product of the coefficient of the b² term and the constant term which sum to give the coefficient of the b- term.
product = 4 × 3 = 12 and sum = + 8
The factors are 2 and 6
Use these factors to split the b- term
4b² + 2b + 6b + 3 ( factor the first/second and third/fourth terms )
= 2b(2b + 1) + 3(2b + 1) ← factor out (2b + 1) from each term
= (2b + 1)(2b + 3)

Rakim's goal is to have at least $500 in his checking
account at the end of the year. The table shows his
activity for the month of January. Will Rakim make his
goal if the month of January's activity is representative
of how much he will save and spend each month?
Explain.
Answers
Answer:
Each month he will save $ 50
Each month he will spend $1,250
Raking will have $600 in his checking account at the end of the year.
Step-by-step explanation:
1300 - 500 - 750 = $50
$50 x 12 month = $600
The required amount Rakim saves and sped each month is $50 and $1250.
Given that,
Rakim's goal is to have at least $500 in his checking account at the end of the year. The table shows his activity for the month of January. Will Rakim make his goal.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Total money he has = 1300
Total money spend = 750 + 500 = 1250
Money he save = 1300 - 1250 = 50
For the condition of at end of the year he must have at least $500
So,
Yearly saving = 50 × 12 = $600, which greater than $500.
The required amount Rakim saves and sped each month is $50 and $1250.

Graph the given equation by evaluating integer values of x from -2 to 2 and plotting the resulting points.
y = -2x - 4
Answers
Graphs are created from functions and equations.
See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]
The equation is given as:
[tex]\mathbf{y = -2x - 4}[/tex]
When x = -2, we have:
[tex]\mathbf{y = -2(-2) - 4 = 0}[/tex]
When x = -1, we have:
[tex]\mathbf{y = -2(-1) - 4 = -2}[/tex]
When x = 0, we have:
[tex]\mathbf{y = -2(0) - 4 = -4}[/tex]
When x = 1, we have:
[tex]\mathbf{y = -2(1) - 4 = -6}[/tex]
When x = 2, we have:
[tex]\mathbf{y = -2(2) - 4 = -8}[/tex]
So, the points on the graph are:
[tex]\mathbf{(x,y) = (-2,0)(-1,-2)(0,-4)(1,-6)(2,-8)}[/tex]
See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]

What is the equation of a line that passes trough (6,-1) and is parallel to the line that has a slope of -2/3?
Answers
Answer:
y=-2/3x+3
Step-by-step explanation:
First, identify the slope you need for your equation. The keyword here is "parallel" so the slope you need is the same as the given slope (-2/3).
Next, use the ordered pair (6,-1); it's on the line that you need to find the equation for. Using slope-intercept form (y=mx+b), plug the -1 in for y, plug the 6 in for x, and plug in your slope of -2/3 for m. Solve for b, your y-intercept. You should get 3.
You have your slope and y-intercept now. Create your equation:
y=-2/3x+3.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Account A:
Balance = $5000
Each week increase = $1000
Amount after one week.
= 5000 + 1000
= 6000
Amount after 2 weeks.
= 6000 + 1000
= 7000
Account B:
Balance = $1
Each week's increase = doubles the amount
Amount after 1 week.
= $2
Amount after 2 weeks.
= $4

Account A has more money after one week.
Account A has more money after two weeks.
