we just need to rewrite 3x+2y+18=0 to look like that
We need to get y by itself
3x+18= -2y
we need y to be positive and to have no number in front of it (no coeficcent)
y= -3/2x-9
the slope is therefore -3/2
Answer:
[tex]-\frac{3}{2} [/tex]
Step-by-step explanation:
3x + 2y + 18 = 0
Equating it with.
ax + by + c = 0, we find:
a = 3, b = 2, c = 18
Slope of the line [tex] =- \frac{a}{b} =-\frac{3}{2} [/tex]

Can you find four examples that are true or a counterexample for the following statement?For every integer n, the value of n^2 + 1 is odd
Solving the expression, it is found a counterexample that when [tex]n = 1[/tex], [tex]n^2 + 1 = 2[/tex] is even.
----------------------
The expression given is:[tex]E(n) = n^2 + 1[/tex]
We want to test for every integer n, that E(n) is odd.----------------------
For n = 0:
[tex]E(0) = 0^2 + 1 = 0 + 1 = 1[/tex]
Odd number.
----------------------
For n = 1:
[tex]E(1) = 1^2 + 1 = 1 + 1 = 2[/tex]
Even, thus, this is the counterexample.

Answer:
1/2 or 0.5 in decimal
Step-by-step explanation:
you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.

What is the value of 9 2/3 minus 4 1/5
Answer:
5 7/15 = D
Step-by-step explanation:
Find a common denominator multiply the many times you did to the denominator to the numerator then subtract.
15 is your common denominator so I would multiply 5 to 2 to get 9 10/15 then I would multiply 3 to 1 to get 4 3/15
Answer:
5 7/15
Step-by-step explanation:
Let's solve your equation step by step.
We will solve it in just 3 simple steps.
Step 1: Converting into Improper Fraction.
Converting into an Improper Fraction is the only way to subtract fractions.
We will turn 9 2/3 into 29/3
First you need to know:
What is a numerator?
What is a denominator?
What is a whole number?
If you know, you can skip this part.
A denominator is the lower number below the line in a fraction. (ex. 2/3 <-- "3" is the denominator)
A numerator is the higher number above the line in a fraction. (ex. 2/3 <---"2" is the numerator)
A whole number is a number that has no fraction or decimal. (ex. "3" or "2" or "7".)
With that said, let's solve.
In 9 2/3, "9" is the whole number. "2" is the numerator, and "3" is the denominator.
We always multiply the whole number by the denominator, then we add the numerator.
So:
(9 x 3) + 2 = 29
Then, we keep the denominator the same. "3".
We then get:
29/3. Which is what we want.
Let's repeat the same steps with 4 1/5.
(4 x 5) + 1 = 21
Keep the denominator : 21/5
Now we are on Step 2.
We currently have 29/3 - 21/5
But we don't have the denominators the same.
We need to find the LCD (Least Common Denominator of 3 and 5.
Since these numbers are less than 10, my trick is to just multiply them together. 3 x 5 = 15, simply put.
Now, let's change all the denominators to 15. Now let's change the numerators.
For the fraction that had 3 as the denominator, let's multiply 5 to it. And for the fraction that had 5 as the denominator, let's multiply 3 to it.
We then get :
145/15 - 63/15
We are now on Step 3.
This step is simple. Just subtract 145 - 63 because the denominators are the same.
145 - 63 = 82
We now have 82/15.
This is the answer, but we always need to simplify it.
How many times can 15 fit into 82? 5. But we have 7 left over.
So we now have :
5 7/15

Four friends shared 7 chocolate bars. Each of them was given an equal share of the chocolate bars. How many chocolate bars did each person get?
A: 4/7
B : 6/8
C: 1 1/4
D: 1 3/4
We are given:
There were 7 chocolate bars, evenly shared between 4 friends
Number of Bars one person will get:
Number of bars one person will get = Number of Bars / Number of Friends
Number of Bars = 7 / 4
but since this number does NOT match any of the given options, we will convert it to a mixed fraction
The number of bars one person will get will be [tex]1\frac{3}{4}[/tex], written as a mixed fraction.
Therefore, the correct answer is option D
Answer:
4 friends =7 chocolate
1 friend =7/4 chocolate =1 3/4 part of chocolate.

Graph the equation.
y= 5(x + 1)^2– 3
HELP!!!
Step-by-step explanation:
the answer is in the attachment
The graph of the function y= 5(x + 1)²– 3 is attached accordingly. See the description of the graph below.
The graph of y= 5(x + 1)²– 3The equation y = 5(x + 1)² - 3 represents a quadratic function.
The graph is a parabola with its vertex at (-1, -3). It opens upward since the coefficient of the squared term (x²) is positive.
The graph is vertically stretched by a factor of 5 compared to the standard quadratic function.
The x-coordinate of the vertex is -1, indicating a horizontal shift of 1 unit to the left from the standard quadratic.

Given;
The figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given right angle triangle,
[tex]\cos (45^\circ)=\dfrac{7}{x}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{7}{x}[/tex] [tex][\because \cos (45^\circ)=\dfrac{1}{\sqrt{2}}][/tex]
On cross multiplication, we get
[tex]1\times x=7\times \sqrt{2}[/tex]
[tex]x=7\sqrt{2}[/tex]
Therefore, the value of x is [tex]7\sqrt{2}[/tex] units.
