The graph of the line y = 4x + 3 is shown below.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
y = 4x + 3
When x = 0, y = 3
When x = 1, y = 4 + 3 = 7
When x = 2, y = 11
Similarly for negative x values, we get,
x = -1, y = -4 + 3 = -1
x = -2, y = -8 + 3 = -5
So on......
So we must get the following coordinates:
(-1, -1), (-2, -5), (0, 3), (1, 7), (2, 11),, ........
Thus,

Delaney would like to make a 5 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds. Let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture.
What is the system that models this situation?
Which of the following is a solution to the system: 2 lb peanuts and 3 lb mixture; 2.5 lb peanuts and 2.5 lb mixture; 4 lb peanuts and 1 lb mixture? Show your work.
Answers
Answer:
p + m = 5, p + 0.2m = 0.6(5)2.5 lb peanuts; 2.5 lb almond mixStep-by-step explanation:
You have peanuts and an 80-20 almond-peanut mix, and you want to know how many pound of each are needed for 5 lb of a 60% peanut mix.
System of equationsThe system of equations relating the pounds of peanuts (p) and the pounds of almond mix (m) will describe the total mixture weight, and the weight of the peanuts.
p + m = 5 . . . . . . total mixture weight is 5 lb
p + 0.20m = 0.60(5) . . . . . weight of peanuts in the 60% peanut mix
SolutionWe can subtract the second equation from the first to eliminate the variable p:
(p +m) -(p +.2m) = (5) -(.6)(5)
0.8m = 0.4(5) . . . simplify
m = 2.5 . . . . . . . . divide by 0.8
p = 5 -m = 2.5
The solution to the system is 2.5 lb peanuts and 2.5 lb mixture.

A circular flower garden has a diameter of 16 feet. At the center of the garden is a circular pool 5 feet in diameter. If a coin is tossed at random into the garden, what is the probability that the coin will land in the pool.
Answers
Answer:
0.0977
Step-by-step explanation:
From the question,
A = πR²...................... Equation 1
Where A = Area of the circular flower garden, R = Radius of the circular flower garden.
Also,
A' = πr²..................... Equation 2
Where A' = Area of the circular pool, r = radius of the circular pool.
If a coin is tossed at random into the garden, the probability that the coin will land in the pool is
Pr = Area of the pool(A')/Area of the garden(A)
Pr = A'/A....................... Equation 3
Substituting equation 1 and 2 into equation 3
Pr = πr²/πR².
Pr = r²/R².................... Equatio 4
Given: R = 16/2 = 8 feet, r = 5/2 = 2.5 feet.
Substitute these values into equation 4
Pr = 2.5²/8²
Pr = 6.25/64
Pr = 0.0977

What is the first month in which the board will see the cumulative total number of cars shipped to Japan exceeded the cumulative total in Vietnam
Answers
The cumulative total in Vietnam j(n) is 23(n-1),cumulative takes into account all data up to the present. In month four, j(n) will be worth more than v(n).
Is the sum the same as the total?The distinction between total and cumulative is that total refers to the entirety of something, whereas cumulative takes into account all data up to the present.
When a new number is added to a series of numbers, the running total is updated by adding the new number's value to the previous running total. Partially sum is another name for it. Running totals serve two distinct objectives.
We take it for granted that you mean that vehicles delivered to Vietnam should be modeled by v(n) = 5 + 11 and those sent to Japan by j(n) = 23(n-1).
In month four, j(n) will be worth more than v(n).

A loan of $9,000 has an annual simple interest rate of 3.5%. What would be the simple interest rate if a loan of $9,000 that is repaid in 6 years has a total cost of $11,052?
Answers
Answer: 3.8%
Step-by-step explanation:
First find the interest cost:
= Amount repaid - Amount borrowed
= 11,052 - 9,000
= $2,052
This cost is the simple interest and because it is the same figure per year, the annual simple interest can be determined by dividing the above by the number of years:
= 2,052 / 6
= $342
Now that we have the simple interest amount, divide it by the amount borrowed to find the rate:
= 342 / 9,000
= 3.8%

If 25% of a number is 20 and 60% of the same number is 48, find 85% of that number
Answers
Answer:
68
Step-by-step explanation:
25% of a number is 20, where the number is 80 because 25% times 4 is 100% and 20 times 4 is 80.
We can check by doing 60% of 80 to see if it is 48. Instead of 60%, we can do 10% of 80, which is 8. Since we divided by 6, we multiply 8 by 6 which is 48.
Since we know 80 is the number, we have to find 85% of 80. First, let's find 5% of 80, which is 4 since 4 x 20 is 80 and 5% x 20 is 100%. Now, 85 divided by 5 is 17, let's multiply 17 by 4 to get 85% of 80. 17 x 4 is 68 which is 85% of 80.

What is the solution of the system of equations y =- 2x 8 y x 4?
Answers
The solution of the system of equations y =0 x=4
To solve the system of equations, we must set the two equations equal to each other and solve for x.
y = -2x + 8
y = x - 4
We start by subtracting the second equation from the first equation.
-2x + 8 = (x - 4)
We then add 4 to both sides of the equation.
-2x + 12 = x
We then subtract 12 from both sides of the equation.
-3x = -12
Finally, we divide both sides of the equation by -3.
x = 4
Now that we have solved for x, we can substitute 6 for x in either equation and solve for y.
y = -2(4) + 8
y = -8 + 8
y = 0
Therefore, the solution of the system of equations is (4, 0).
