Step-by-step explanation:
[tex](-4,-5),(-3,-3)[/tex]
Coordinate GraphA coordinate graph is made up of two number lines that are perpendicular to each other. Axes are the names given to these numerical lines. Ordered pairs indicate positions on a coordinate graph. An ordered pair [tex](x,y)[/tex] is a coordinate graph location.Given equation is [tex]y=2x+3[/tex]
Put [tex](x,y)=(-4,-5)[/tex]
[tex]-5=2(-4)+3\\-5=-5[/tex]
Put [tex](x,y)=(-3,-3)[/tex]
[tex]-3=2(-3)+3\\-3=-3[/tex]
Put [tex](x,y)=(-1,0)[/tex]
[tex]0=2(-1)+3\\0\neq 1[/tex]
Put [tex](x,y)=(-1,-4)[/tex]
[tex]-4=2(-1)+3\\-4\neq 1[/tex]
So, [tex]\boldsymbol{(-4,-5),(-3,-3)}[/tex] lie on the graph [tex]y=2x+3[/tex]

Explain how to use ratio tables and compare ratios.
Answers
Answer:
You should ALWAYS do everything by the same value for using the tables Step-by-step explanation:
if one side gets multiplied so should the other, so let's say you had 2:4 if you are multiplying the 4 by 3, you should also multiply the 2 by 3.
Comparing ratios:
In order to compare a ratio you must have a number that is constant, basically in other words a common number. A number that almost is always the multiplied, or divided by the same amount.

Can you find the slope and type the correct code?
Answers
Answer:
1. (3,19) and (-1,-13)
to find the slope you need to do [tex]\frac{y2-y1}{x2-x1}[/tex]
Hence [tex]\frac{-13-19}{-1-3}[/tex]= 32/-4=-8
2. Take two points on the graph:
(-2,3) and (1,0)
Know that to calculate the slope you do
[tex]\frac{rise}{run}[/tex]= 4/2= 2
3. To find the slope in a table you need to choose any two points and utilize the following formula: [tex]\frac{y2-y1}{x2-x1}[/tex]= [tex]\frac{-16-(-8)}{2-1}[/tex]=-8/1= -8
4. Like in #1 we take the two points and plug it into the formula:
[tex]\frac{8-(-10)}{0-9}[/tex]=18/-9= -2

Let x equal small rugs and y equal medium rugs. Which of the following system of equations can be used to determine how many of each type of rug was sold? (5 points)
A 40x + 40y = 80
14x + 25y = 1340
B x + y = 80
14x + 25y = 1340
C x + y = 39
11x + 15y = 80

How many sides does the polygon measures 160 degrees how many sides does the polygon have???
Answers
Answer:
18 sides
Step-by-step explanation:
I'm not sure what the question is, but this is what I think the question is.
"An interior angle of a regular polygon measures 160 degrees. How many sides does the polygon have?"
The sum of the measures of the interior angles of a polygon of n sides is
(n - 2)180
If the polygon is a regular polygon, then the measure of each interior angle is
(n - 2)180/n
Here, we are told an interior angle measures 160 deg.
(n - 2)180/n = 160
(n - 2)180 = 160n
(n - 2)18 = 16n
(n - 2)9 = 8n
9n - 18 = 8n
n = 18
Answer: 18 sides
A card is drawn at random from a standard pack of 52 playing cards find the probity of drawing a heart or a club
Answers
Answer:
1/2
Step-by-step explanation:
From the question, there are 13 cards of heart and 13 card of club in each suit in each deck.
P(drawing heart) = 13/52
P(drawing club) = 13/52
And we know total standard pack =52
P(drawing a heart or a club)
= number of favourable outcome/ total Number of outcome
P( drawing heart or club) =( 13+13)/52
=26/52
=1/2

ANSWER PLEASE !!!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!
Answers
Answer:
62 degrees
Step-by-step explanation:
First, it is important to note that all three angles in a triangle add up to be 180 degrees, and if you draw a straight line extending off the side of a triangle, the outside angle and the inside angle are supplementary (they add to be 180 degrees). So,(3x+3)+(2x+4)-180=measure angle F, and 180-(7x-5)=measure angle F according to the rules respectively. Since both of these equations are equal (they both equal the measure of angle F) we can set them equal to each other to find the value of x=> 180-(7x-5)=(3x+3)+(2x+4)-180=> 180-7x-5=3x+3+2x+4-180. Now combine like terms=>175-7x=5x-173. Now, add 7x to both sides and add 173 to both sides to get the variables on one side of the equation=> 175+173-7x+7x=5x+7x-173+173 (the 7x and -7x on the left side and the 173 and -173 on the right side cancel out) =>348=12x. Divide both sides by twelve to find x=> 29=x. Now, plug 29 into what is given for angle FDE=> 2(29)+4=
58+4=
62 degrees

Suppose a Hospitality Management student is randomly picked. What is the probability that the student has visited 30 or fewer states?
Answers

Answer:
66%
Step-by-step explanation:
The categories are mutually exclusive, so we have ...
P(≤30) = P(1–10) +P(10–20) +P(20–30) = 5% +16% +45%
P(≤30) = 66%
The probability is 66% that a randomly chosen student has visited 30 or fewer states.

Multiple choice question: A square mosaic is made of small glass squares. If there are 196 small squares
in the mosaic, how many are along one edge? Image is of a mosaic, not the
problem. *
O 14 squares
O 49 squares
O 98 squares
O 16 squares
Answers
Answer:
14 squares
Step-by-step explanation:
1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares
2. Area is L×W, so in this case A×A=196
3. We can test this by replacing A with 14 and seeing if the answer is correct.
4. 14×14=196 is true
This can also be done by finding the square root of 196.

What is the value of x, if the equation 2(x + 60) + 2(30) = 200
Answers
This is because:
2(x+60)+2(30)=200
•distribute the 2s into each parentheses
2x+1200+60=200
•combine like-terms
2x+1260=200
•isolate 2x by subtracting 1260 from both sides of the equation
2x=200-1260
•subtract 1260 from 200
2x= -1260
•divide both sides by 2 so you can have x all alone
2x/2= -1260/2
Hence
x= -530
