Answer:
1 is a polygon. 2 and 3 are not.
Step-by-step explanation:
For the first shape:
This shape is a polygon because the sides of the shape are straight, have angles, and do not intersect.
For the second shape:
This is not a polygon because of the lines being bent and having curvature.
For the third shape:
This is not a polygon because the lines intersect at a point.
For a shape to be a polygon, it must have 3 or more straight sides, angles, and no intersections.

Write an equation of a line with the given slope and y-intercept.
m = (1)/(4), b = -(3)/(4)
A. y= 4x - (3)/(4)
B. y= (1)/(4)x - (3)/(4)
C. y= (1)/(4)x + (3)/(4)
D. y= -(3)/(4)x + (1)/(4)
Answers
Answer:
B. y= (1/4)x-3/4
The equation of a straight line it is found by using
Y= mx + c
Where m is the gradient
and c is the y intercept
Answer:
C. y= (1)/(4)x + (3)/(4)
Step-by-step explanation:
Equation of a line is y=mx+b
where m is the slope and b is the y-intercept.
y= (1)x + (4)
so
the equation of this line would be,
y = x + 4
y=x+4
Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.
Answers
Answer:
Sample third quartile appears to be an unbiased estimator of the population third quartile.

Answers
Answer:
a 90
b 90
a 8x+40
b 4y-36
c -6n-3
d 7x+7
e -10x+30
f 4/1x+2/1
This start with the first question (3)
Find the product of 5(18) and 5(18) = 90
To get that is 5(18) = (5 x 18 = 90)
So now we have to do the math for both A and B and find out which one is 90
A 5(10+8) : 10 + 8 = 18 so (a) = 5(18)
B 5(20-2) : 20 - 2 = 18 also well
I think (a) would be your best bet. For question (3)
Alright question 4
(a) = 8x + 40
(b) = 4y - 36
(c) = -6n - 18
(d) = 7x + 7
(e) = 30-10x
(f) = 4x + 2

Question: What are the solutions to this graph?
Answers
Answer:
The solution to the graph are x = -2 and x = 2
Step-by-step explanation:
Here, we want to get the solution to the graph
As we can see, the graph is parabolic; which is a property of a quadratic polynomial
The solution refers to the value at which the graph plot crosses the x-axis
In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis
We can see this happen at two points
These are the points x = -2 and x = 2

Use the information given to write the equation for the quadratic function.
a. The x-intercepts are (-4, 0) and (3,0), and the parabola opens down.
b. The vertex is (-8, -2), and the parabola opens up.
Answers
Answer:
y = -x² - x/22 + 6/11
Step-by-step explanation:
Standard form, is y = ax² + bx + c
We need to use standard form (though we could use vertex form, but it is easier to do standard form)
Substitute the x and y values that they give into y = ax² + bx + c
Because the parabola passes through...
(-4, 0), then 0 = (-4)²a + (-4)b + c
(3, 0), then 0 = 9a + 3b + c
(-8, -2), then -2 = 64a - 8b + c
So, we get this system:
16a − 4b + c = 0
9a + 3b + c = 0
64a − 8b + c = −2
Because you are learning about parabolas, I am assuming that you can solve a system, but the answers are:
a = -x²/22
b = -x/22
c = 6/11
So, the equation of the parabola is:
y = -x²/22 - x/22 + 6/11
I hope this helps! Feel free to ask any questions!

by using substitution method
Answers
Answer:
y = -2x
y = 3x + 5
<=> 3x + 5 = -2x
y = -2x
<=> 5x = -5
y = -2x
<=> x = -1
y = -2x
<=> x = -1
y = (-2)(-1) = 2
so (x; y) = (-1; 2)
