Answer:
In graphing inequalities, the first thing to do is graph the equation first irregardless of the inequality symbol. In the given problem, the equation to be graphed is f(x) = 2/9x + 3. Since it has a general form of y=mx + b, this is a linear function. Plot the graph by assigning arbitrary points of x, then you get the corresponding f(x) values. Graph the x values against the f(x) values. The blue line the attached picture will be formed.
Next, you solve the equation by finding x. Just don't mind the inequality symbol:
2/9 x + 3 > 4 5/9
2/9x > 4 5/9 - 3
2/9x > 14/9
x > 14/9 ÷ 2/9
x > 7
Hence, the value of x must be greater than 7. To show this in the graph, find the line where x=7. Create a partition using that line, then shade the rest of the portion where x is greater than 7 until infinity.

What is the initial value?
A. -8
B. -5
C. 0
D. 7
Answer:
A. -8
Step-by-step explanation:
Given the values of the function in a table, to determine the initial value of the function, you need to determine where x = 0.
Since the function is linear, the rate of change will be constant/the same.
To find the rate of change, you need to divide the change in the y value by the change in the x value.
X Y
+2↓ -5 | 7 ↓ -6
+2↓ -3 | 1 ↓ -6
+2↓ -1 | -5 ↓ -6
1 | -11
_____________
Since y changes by -6 and x changes by +2 every time, ∆Y/∆X = -6/+2 [Reduce] = -3/+1.
Slope = -3.
This means that y will decrease by 3 units every increase of 1 unit in x.
If (-1, -5) is a point which means that -1 is x when -5 is y.
We can apply the rate of change to see where x = 0.
So -5 + 1(-3/+1) → -5 + -3 = -8
Henry painted a picture of his house on canvas. The actual width of
the driveway is 20 feet. If it is represented with a width of 4 inches on
the canvas, what was the scale factor used?
Answer:
The scale factor would be -5.
Step-by-step explanation:
If the driveway is 20 feet but 4 foot on the canvas. Then 20/4 is 5. But since the width is going from 20 to 4, the numbers are going down to it would be a negative scale factor. If it was going from 4 width to 20 width, the scale factor would be a positive 5.
the local market is selling a pound of bananas for $0.55. if you bought 8 bananas for $1.44, what is the unit rate?
Answer:
$0.18
Step-by-step explanation:
Given that :
Number of bananas purchased = 8
Cost at which the 8 bananas were purchased = $1.44
The unit price of bananas can be obtained using the relation :
Total Cost of bananas / number of bananas
Unit price = $1.44 / 8
Unit price = $0.18
Price per unit of banana = $0.18
1 5/16 + 1 5/16=_____
Answer:

Find the quotient. Write your answer in scientific notation, (3.6 x 10 to the power of 7) divided by (7.2 times 10 to the 7)
Given:
The given expression is:
[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]
To find:
The value of the quotient.
Solution:
We have,
[tex]\dfrac{3.6\times 10^7}{7.2\times 10^7}[/tex]
It can written as:
[tex]=\dfrac{3.6}{7.2}\times \dfrac{10^7}{10^7}[/tex]
[tex]=\dfrac{1}{2}\times 1[/tex]
[tex]=0.5[/tex]
It can be rewritten as:
[tex]=5\times \dfrac{1}{10}[/tex]
[tex]=5\times 10^{-1}[/tex]
Therefore, the value of the quotient is [tex]5\times 10^{-1}[/tex].

What is addition of two fractions?To add fractions there are three simple steps:
Step 1: Make sure the bottom numbers (the denominators) are the same. Step 2: Add the top numbers (the numerators), put that answer over the denominator.
Step 3: Simplify the fraction (if possible)
Given, after six months, she improved her record by 1/15 of a kilometer. After a year, she further improved her record by 1/12 of a kilometer.
Now, 5/6 + 1/15 + 1/12
LCM of denominators 6, 15 and 12 is 60.
50/60 + 4/60 + 5/60
= 59/60
Therefore, Emma's best record is 59/60 kilometers per minute.

Alejandra correctly wrote the equation y-3 = (x - 10) to represent a line that her teacher sketched. The teacher
then changed the line so it had a slope of 2, but still went through the same point. Which equation should Alejandra
write to represent the new line?
Answer:
The question which ask to select among the choices the equation that Alejandria should write to represent the new line where as the equation she wrote is y-3=x-10 and the answer would be that the form in this equation is y=x-13 and if the slope is 2 then it is y=2x-13
