Answer:
189$
Step-by-step explanation:
30% of 270 = 81
270-81=189
Answer:
The sale price is $189.
Step-by-step explanation:
Rule:
To find the percent of a number, change the percent to a decimal by moving the decimal point of the percent two places left. Then multiply it by the number.
Example:
Find 20% of 200.
Change the percent, 20, to a decimal by moving the decimal point of 20 two places left.
20% = 0.20
Now multiply 0.20 by 200.
0.20 × 200 = 40
Answer to the example: 20% of 200 is 40
Here is the solution to your problem:
The suit has a regular price of $270.
The percent off is 30%.
First, we find the dollar amount of the discount.
30% of $270 = 0.30 × $270 = $81
The dollar mount of the discount is $81.
Now we subtract the dollar amount of the discount from the original price of $270.
$270 - $81 = $189
Answer: The sale price is $189.

I need help finding the rule.
Answer:
y=3x+1
Step-by-step explanation:
The question is asking for an equation in slope-intercept form. This is y=mx+b, where m is slope and b is y-intercept. The slope is the change is y over the change in x. The y value changes 3 and the x value changes 1. So, the slope is 3/1 or just 3. The y-intercept is the value where the line intersects with the y-axis. Additionally, the y-intercept will have an x-value of 0. On the table, you can see that y=1 when x=0. Thus, the y-intercept is 1. Put the two values into the equation and you get y=3x+1.

Elise says, "If you subtract 17 from my number and multiply the difference by -3, the result is -61."
What is Elise's number?
Answer:
Elise's number is 112/3.
Step-by-step explanation:
You can form the equation: [tex]\left(x-17\right)\cdot -3=-61[/tex]
Solution: [tex]\frac{\left(x-17\right)\left(-3\right)}{-3}=\frac{-61}{-3}[/tex]
[tex]x-17=\frac{61}{3}[/tex]
[tex]x-17+17=\frac{61}{3}+17[/tex]

Enter your answer as a mixed number in simplest form in the box.
x =
The value of x is 2.0833.
Given that,
The equation is 32.3 = 14.8 + 18.4x.We need to find the value of x.Based on the above information, the calculation is as follows:
32.3 = 14.8 + 8.4x
32.3 - 14.8 = 8.4x
17.5 = 8.4x
x =2.0833

When a system ofnliner equations has x-terms that are opposites how is x eliminated?
Answer:
When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable. We can eliminate the x-variable by addition of the two equations.

Step-by-step explanation:
Identify the domain and range, then tell if the relation is a function
Answer:
D: (-3, 0, 2, 9)
R: (4, 6, 7)
This relationship is a function as there are no two input that have the same output.
Step-by-step explanation:
This relationship is a function as there are no two input that have the same output.
The range is the second output (y-value) which is (4, 6, 7).
The domain is the first element (x-value) of a relation or function which is (-3, 0, 2, 9)

Write an equation in slope-intercept form from the following points:
(-4,6) and (0,7)
Answer:
y = 1/4 * x + 7
Step-by-step explanation:
We start with the equation for slope-intercept y = mx + b -
Y is any y point on the line. X is any x point on the line. M is the slope of the line. B is the y-intercept of the line.
We first find the slope by using this equation (y2 - y1) / (x2 - x1) -
(7 - 6) / (0 - (-4))
1 / (0 + 4)
Slope = 1/4
Now we insert the slope into the equation -
y = 1/4 * x + b
As said before, Y is any y point on the line and X is any x point on the line, so we can choose a random point and insert it in to find the y-intercept -
(The equation already tells you the y-intercept (0, 7) but for checking, we will insert the point in too)
7 = 1/4 * 0 + b
7 = b
b = 7
The y-intercept of the line is (0, 7)
We insert the y-intercept in the equation -
y = 1/4 * x + 7
y = 1/4 * x + b is our answer to the problem.
Find the nth term of this number sequence
15, 12, 9, 6, ...
Answer:
18-3n
Step-by-step explanation:
The nth term of this number sequence is,
⇒ a(n) = 15 - 3 (n - 1)
What is Arithmetic sequence?An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.
Given that;
The sequence is,
15, 12, 9, 6..
Now, We can find the nth term as;
First term (a) = 15
Common difference (d) = 12 - 15 = - 3
We know that;
The nth term of the arithmetic sequence is,
⇒ a(n) = a + (n - 1) d
Hence, We get;
The nth term of this number sequence is,
⇒ a(n) = a + (n - 1) d
⇒ a(n) = 15 + (n - 1) (- 3)
⇒ a(n) = 15 - 3 (n - 1)
Thus, The nth term of this number sequence is,
⇒ a(n) = 15 - 3 (n - 1)

randall wants to fill up 40 percent of the scare containers. what is this number as a fraction
Answer:
2/5
Step-by-step explanation:
Normally, percentage is expressed in 0 - 100 so for Randall to fill up 40% of his container, that means he'd fill out 40 out of a hundred. That's 40/100 which simplified will give you 2/5
Express in vertex form
Y=2x^2 - 2x - 5
Answer:
y = 2(x - [tex]\frac{1}{2}[/tex] )² - [tex]\frac{11}{2}[/tex]
Step-by-step explanation:
y = 2x² - 2x - 5 ← factor out 2 from the first 2 terms
= 2(x² - x) - 5
Using the method of completing the square
add/subtract (half the coefficient of the x- term)² to x² - x
y = 2(x² + 2(- [tex]\frac{1}{2}[/tex] ) x + [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{4}[/tex] ) - 5
= 2(x - [tex]\frac{1}{2}[/tex] )² + 2(- [tex]\frac{1}{4}[/tex] ) - 5
= 2(x - [tex]\frac{1}{2}[/tex] )² - [tex]\frac{1}{2}[/tex] - 5
= 2(x - [tex]\frac{1}{2}[/tex] )² - [tex]\frac{11}{2}[/tex] ← in vertex form

The relationship between the number of ounces of tea purchased and the total cost of the tea is proportional as shown in the graph.
Which equation models this relationship?
y = 7/4x
y = 4/7x
y = 4/1x
y = 1/4x
Answer: y= (7/4)x
Step-by-step explanation:
Build a table of representative values and then calculate the slope between any 2 of the points. I'll pick (2,3.5) and (8,14) [See attachment. ]
The slope is the Rise/Run:
Rise = (14 - 3.5) = 10.5
Run = (8-2) = 6
Slope = Rise/Run: (10.5/6) = 1.75
The equation should read y = 1.75x.
None of the options works, as written, but note that 7/4 looks close to 1.75. In fact, 7/4 = 1.75.
Use the equation y = 1.75x and enter several values of x (the ounces purchased) and y (the total cost of the purchase). The attachment summarizes the results (Predicted), along with the actual values (Actual) taken from the graph. Excellent correlation, considering the difficulty in making precise graph readings.
Therefore y = (7/4)x
