Answer:
1. domain and range are all real numbers
2. the relation is linear
Step-by-step explanation:
When the graph of a function is a straight line, the relation is linear. (That's what linear means.)
A linear relation is of degree 1, so has odd degree. Any odd-degree polynomial function has a domain and range of "all real numbers."
Answer:
1. Domain : all the real numbers
Range = all the real numbers
yes, this relation represents a linear function. (linear functions are always a straight line when graphed.)
3x-y=2
2x-y=3
Solve with elimination
Answer:
5
Step-by-step explanation:
{
3x−y=2
2x−y=3
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x−y=2,2x−y=3
Subtract 2x−y=3 from 3x−y=2 by subtracting like terms on each side of the equal sign.
3x−2x−y+y=2−3
Add −y to y. Terms −y and y cancel out, leaving an equation with only one variable that can be solved.
3x−2x=2−3
Add 3x to −2x.
x=2−3
Add 2 to −3.
x=−1
Substitute −1 for x in 2x−y=3. Because the resulting equation contains only one variable, you can solve for y directly.
2(−1)−y=3
Multiply 2 times −1.
−2−y=3
Add 2 to both sides of the equation.
−y=5
Divide both sides by −1.
y=−5
The system is now solved.
x=−1,y=−5
At what position on the number line is the red dot located, thank you
Answer:
Root under 39
Step-by-step explanation:
Just multiply the times like 5, 5.25, 5.50, 5.75, 6, 6.25 , 6.50....in such way and calculate...
Answer:
D. [tex]\sqrt{39}[/tex]
Step-by-step explanation:
You don’t even need a calculator for this task.
You can see that the dot is 6.2, but lets just think what number should give us 6 in [tex]\sqrt{x}[/tex], and we know it’s [tex]\sqrt{36}[/tex], but since our dot equal 6.2, we see from our choise that the best answer is [tex]\sqrt{39}[/tex].

Is it possible to add the data for an additional hike to the line plot so that the range increases but the median does not change?
Answer:
Not possible
Step-by-step explanation
Range is the difference between the highest and lowest data value in a data set. It is used to define the spread on data on the graph. Higher the range higher will be spread of data.
Whereas median is the middle value(odd number of data values) or average of the middle values(even number of data values) in a data set.
Therefore, adding an additional data value will surely change range( increase in case, the value is higher than other values) at same time it will also effect the median of the data set. So, it not possible to add the data for an additional hike to the line plot so that the range increases but the median does not change

i told you the answer is -8
Answer:all
recall that the inside angles of a triangle add up to 180
Step-by-step explanation:
now add up all the angles and make it equal to 180 :)
as follows
X+58+45+85 = 180
now use algebra ... and solve for X :)
X = 180-58-45-85
my calculators tells me....
X = -8
what does that answer mean?
it's saying ... like this 58-8 is that angle.. does that help ? :)

Answer:
1/2 is the slope
Step-by-step explanation:
Slope is rise over run
it goes up 1 and across 2
therefore the slope is 1/2
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]slope = \frac{rise}{run} = \frac{1}{2}[/tex]
Write a quadratic function for the graph

The equation y=21.2x represents Austin's earnings in dollars and cents, y,
for working x hours. Find the rate of change.
Given:
The equation is
[tex]y=21.2x[/tex]
Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=21.2x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=21.2[/tex]
Therefore, the rate of change is 21.2 dollar and cents per hour.

-6x-10y=-18 -3x+10y=36
Answer:
problem one
x = 3- 5y/3
y = 9/5 - 3x/5
problem 2
x= -12 + 10y/3
y= 18/5 + 3x/10
Step-by-step explanation:
I need to solve for x btw these are corresponding angles
Step-by-step explanation:
As we know corresponding angles are equal so
6x - 100° = 2x + 4° < being corresponding angles>
6x - 2x = 100 ° + 4°
4x = 104°
x = 104° / 4
x = 26°

Please help!!!part a
Answer:
b = 76°
Step-by-step explanation:
Hi there,
It is important to know that the sum of all the angles in any triangle equals 180°.
For this problem, we can write the following equation:
32° + 72° + b° = 180°
104° + b° = 180°
b° = 76°
Hope my explanation helps. Cheers.

4.) A store is having a sale in which all items are marked 30% off.
4a.) Which equation represents the selling price, s, in dollars, of an item originally
priced p dollars after a markdown of 30%?
a.) s=0.3p
b.) s=0.7p
c.) p=0.35
d.) p=0.75
Answer:
0.70p
Step-by-step explanation:
"30% off" means paying only 70% of the original sales price (subtracting 30% from 100% yields 70%). Next, find the decimal equivalent of 70%:
It is 0.70. Finally, multiply the price p by 0.70: 0.70p (Answer b)
