solve the system of equation-5x+2y=9 y=7x
The system of equations -5x + 2y = 9 and y = 7x is solved using substitution, yielding the solution x = 1 and y = 7.
To solve the system of equations -5x + 2y = 9 and y = 7x, we can use substitution since the second equation gives us 'y' in terms of 'x' directly. We substitute 7x in for y in the first equation:
-5x + 2(7x) = 9
-5x + 14x = 9
9x = 9
x = 1
Now that we have the value for x, we can find y using the second equation:
y = 7(1)
y = 7
Therefore, the solution to the system of equations is x = 1 and y = 7.

Help I do not understand how to find the area of circles
The table shows five transactions and the resulting account balance in a bank account, except some numbers are missing. Fill the missing numbers
Answer:
transaction 3 (account balance) = 143
transaction 4 (account balance) = -86
transaction 5 (transaction amount) = 86
Step-by-step explanation:
From the table it is seen that after transactions the account balance either increases or decreases.
Transaction 1
transaction amount was 200 while account balance became 200
Transaction 2
the initial startup balance will be = transaction amount + current account balance which is = 147 + 53 = 200 .
Note: the account balance of the previous transaction becomes the initial account balance of the next transaction
Transaction 3
account balance = initial account balance + transaction amount
= 53 + 90 = 143
Transaction 4
account balance = initial account balance + transaction amount
= 143 + ( - 229 ) = - 86
Transaction 5
transaction amount = account balance - initial account balance
= 0 - ( -86 ) = 86
The account balance after transaction 3 is 143
The account balance after transaction 4 is -86
Transaction amount of transaction 5 is 0

Solve using distributive property 6 x 4.4
Final answer:
To solve the equation 6 x 4.4 with the distributive property, multiply 6 by each part of 4.4 (which is divided into 4 and 0.4) separately and then add the results together. This yields 24 + 2.4, which equals 26.4.
Explanation:
To solve the multiplication problem 6 x 4.4 using the distributive property, we can break down the number 4.4 into 4 and 0.4. Then we distribute the multiplication over these two addends separately.
This can be written as:
6 x (4 + 0.4) = (6 x 4) + (6 x 0.4)
Next, we solve each part of the equation:
6 x 4 = 24
6 x 0.4 = 2.4
Finally, we combine these two results to get the final answer:
24 + 2.4 = 26.4
Thus, 6 multiplied by 4.4 equals 26.4.

Shanice's car is traveling 10 miles per hour slower than twice the speed of Brandon's car. She covers 93 miles in 1 hour 30 minutes. How fast is Brandon driving?
Shanice's rate: 93 / 1.5 = 62 miles per hour
she is 10 miles slower than twice the speed of Brandon
62 +10 = 72
72/2 = 36
Brandon is driving 36 miles per hour

A 9cm wife cross section pipe has a height of 13cm . What is the volume of the pipe
To find the volume of a pipe, use the formula V = Ah where A is the cross-sectional area and h is the height of the pipe. Substituting the values given, the volume of the pipe is 826.805 cm³.
The volume of the pipe can be calculated using the formula V = Ah, where A is the cross-sectional area and h is the height of the pipe. In this case, the cross-sectional area can be found using the formula for the area of a circle, A = πr². Given that the pipe has a diameter of 9 cm, the radius (r) is half of the diameter, which is 4.5 cm.
Substitute the values into the formulas to find the volume: A = π(4.5 cm)² = 3.142 x 20.25 cm² = 63.585 cm². Now, calculate the volume using V = 63.585 cm² x 13 cm = 826.805 cm³.
Suppose 18 gallons of water care out of a pipe in 6 minutes. What was the rate in gallons per minute?

Unit 4 Review & Sample Work Inequalities Solving and Graphing Inequalities Graph the solution sets to the inequalities on the number lines below.
https://gyazo.com/00a920c17b5ad39849d47d70484cca0c
Graphing the solution sets to inequalities involves using open or closed circles to represent non-inclusive or inclusive endpoints and shading the number line to indicate the direction of the inequality.
Explanation:To graph the solution sets to the inequalities on number lines, we need to understand and apply the concepts of inequalities and number line graphing. If an inequality has a 'less than' (<) or a 'greater than' (>) symbol, we use an open circle on the number line to indicate that the endpoint is not included in the solution. Conversely, if an inequality includes 'less than or equal to' (\u2264) or 'greater than or equal to' (\u2265), we use a closed circle to show that the endpoint is part of the solution set. The inequality symbol will also determine the direction in which we shade the number line: to the left for 'less than' and to the right for 'greater than'.
For example, if we have an inequality x > 3, we place an open circle at 3 and shade the number line to the right of 3, indicating all numbers greater than 3 are included in the solution set. If the inequality is x \u2265 5, we place a closed circle at 5 and shade to the right, including 5 and all numbers greater than it. Similarly, with x < -2, an open circle would be placed at -2 and the line shaded to the left. Lastly, for x \u2264 -4, a closed circle at -4 with the line shaded to the left indicates the solution set.

The function f(x)=5(x−1) is shown on the coordinate plane. Select from the drop-down menus to correctly describe the end behavior of f(x) . As x decreases without bound, the graph of f(x) . As x increases without bound, the graph of f(x) . An exponential curve graphed on a coordinate plane with horizontal x-axis ranging from negative 4 to 4 in increments of 1. The vertical y-axis ranges from negative 5 to 5 in increments of 1. The curve begins from the second quadrant. The curve increases through begin ordered pair 0 comma 0.2 end ordered pair. The curve passes through begin ordered pair 1 comma 1 end ordered pair and moves away from the positive y-axis.
Answer: As x decreases without bound the graph f(x) decreases, as x increases without bound the graph of f(x) increases.
Step-by-step explanation:
Since, the given function is , [tex]f(x) =5(x-1)[/tex]
If [tex]x\rightarrow -\infty[/tex] then [tex]f(x)\rightarrow -\infty[/tex]
that is, we can say, as x decreases without bound the graph f(x) decreases.
While, If [tex]x\rightarrow +\infty[/tex] then [tex]f(x)\rightarrow +\infty[/tex]
That is, we can say, as x increases without bound the graph f(x) increases.
thus, we can say first option represents the correct end behavior of f(x).
