Answer: 2x2 + 4xy + 4y2 = 0
2 xx + 4xy + 4yy = 0
...xx + 2xy + y*y + yy = 0
(x + y)^2 + yy = 0
if x is a constant
... 2yy + 4xy - 2xy + xx = 0
(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0
2(y + x)^2 - 2xx - 2xy + xx = 0
2(y + x)^2 - xx - 2xy = 0
2(y + x)^2 - xx - 2xy +yy - yy = 0
(x + y)^2 + yy = 0
x = i*y - y
if x = r cos a
y = r sin a
cos a )^2 + cos a sina + sin a)^2 + sin a)^2 = 0
cos a sin a + sin a)^2 = -1

When its asking for the vertical intercept its asking " at what points does the equation cross the vertical axis( y axis) so its pretty much asking for the y intercept¨
In the graph shown below the y intercept is 0 so the coordinates of the vertical intercept would be (0,0)
When its asking for the horizontal intercept its asking " at what points does the equation cross the horizontal axis ( x axis ) so its pretty much asking for the x intercept."
In the graph shown below the x intercept is 0 so the coordinates of the horizontal intercept would be (0,0)

Answer:
a:95
b: a=75
Step-by-step explanation:
For a:
The angles are supplementary meaning they add to 180º. So you can set up an equation: x + 85 = 180
Subtract 85 from both sides:
x = 95º
For b:
Since it's an isosceles triangle (2 congruent sides), the base angles are equal to each other. So a = 75º

Monthly grocery cost based on the average number of shopping trips is predicted using the least-square regression line, ŷ = 275.3 + 90.7x, where ŷ represents the predicted monthly expense and x represents the average number of trips. A shopper visits the grocery store an average of 3.2 times and has a monthly cost of $520. What is the residual for the shopper?
45.54
76.47
−45.54
−76.47
90.7
Answer:
−45.54
Step-by-step explanation:
Just took the test
The residual for the shopper will be equal to -45.54. Hence, option C is correct.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given data provided in the question,
The given equation is,
y = 275.3 + 90.7 x
Here, x is the number of trips and y is the total monthly expense.
Then,
Shopper monthly cost = $520
Number of visits by the shopper in a month = 3.2
So, the residual for the shopper will be,
$520 = 275.3 + 90.7 (3.2)
$520 = 275.3 + 290.24
= -45.54

Do the following set of points represent a function?Explain your answer (2,3),(3,8),(-1,4),(1,8)
Answer:
Yes.
Step-by-step explanation:
Yes.
To have a function, you cannot use the same value for an x-coordinate more than once. Here, each value of an x-coordinate is used only once, so it is a function.
Answer:
Yes.
Step-by-step explanation:
It is a many-to-one function. Both 3 and 1 map to 8.
2 maps to to 3 and -1 maps to 4 which is one-to-one.
There are no one to many mappings so it is a function.

a rectangular playground has its length more than its breath by 2 m find the length and breadth of the playground if area of playground is 440 sq.m.
Answer:
Length = 22m
Breadth = 20m
Step-by-step explanation:
Given:
Area = 440 m²
Let the breadth be x m
According to the question:
Length = (x+ 2) m
Area of a rectangle = length × breadth
Substitution the values of area, length and breadth
440 = (x+2) × x
440 = x² + 2x
x² + 2x - 440 = 0
x² + 22x - 20x - 440 = 0
x (x + 22) - 20 (x + 22) = 0
(x + 22) (x - 20) = 0
x = -22 and 20
Since the value of breadth cannot be in negative, therefore the value of breadth will be 20 m.
Length = (x + 2)
⇒ 20 + 2
⇒ 22 m

Could someone help me with this due in 2 hours!!!!! Been working on this for 6 hours choosing brainliest!!!!
Step-by-step explanation:
The Triangle Inequality Theorem states that any two sides of the triangle must add up to be greater than the third side.
Question #1Here we have a triangle that has side lengths of 10 in, 11 in, and ? in.
This last side length must add up to 10 in to be greater than 11 in.
The least possible whole number that would fit this description would be 2 in.
10 in + 2 in > 11 in10 in + 11 in > 2 in 11 in + 2 in > 10 inThe missing side length should be labeled as 2 inches.
Question #2We are given a triangle with side lengths of 6 in and 8 in. We are asked to choose all answers that apply from this list:
2 in3 in4.5 in 6.5 in10 in13.5 in14 in15.5 inWe can tell that 2 in cannot be an answer since 6 in + 2 in is not greater than 8 in.
We also know that 14 in and 15.5 in cannot be part of the answer choices since 8 in + 6 in = 14 in, and this is not greater than 14 in or 15.5 in.
The rest of the answer choices will form a triangle if we follow the Triangle Inequality Theorem. You can test it out yourself to check.
Therefore, the answer choices are:
B. 3 inC. 4.5 inD. 6.5 inE. 10 inF. 13.5 in Question #3We are given these possible side lengths:
2, 4, 5, 6, 10Let's test out which combinations will create a triangle.
2 + 4 > 5 5 + 2 > 44 + 5 > 2The straw lengths 2, 4, and 5 will form a triangle.
2 + 5 > 6 5 + 6 > 22 + 6 > 5The straw lengths 2, 5, and 6 will form a triangle.
2 + 6 > 4 4 + 2 >/ 6The straw lengths 2, 4, and 6 will NOT form a triangle.
4 + 5 > 66 + 5 > 4 4 + 6 > 5The straw lengths 4, 5, and 6 will form a triangle.
5 + 6 > 10 10 + 5 > 66 + 10 > 5The straw lengths 5, 6, and 10 will form a triangle.
We have no more straw lengths that will form a triangle, since adding up each remaining pair of given straw lengths do not output a value greater than another number.
