Answer:
y=-2x+3/2 or y=-2x-3/2
Step-by-step explanation:
so the line starts at the negative 2 on the y-axis and -3 is on the x-axis then so you start at the -2 on the y-axis and go over and count how many times it goes over and then count how many times it goes down to the next dot.
Paola is selling bags of homemade caramel corn for a club fundraiser. The amount she makes depends on the number of bags sold. Based on this information, which statement explains what (8, 12) means?
Answer:
She realised $12 from selling 8 bags of caramel corn
Step-by-step explanation:
Given
(8, 12)
Required
Determine what it means based on the available information
A function is always written as (x,y)
Where x is dependent on y
By comparison,
x = bags of caramel corn = 8
y = amount realised = 12
Assuming the currency is in dollars
Conclusively,
She realised $12 from selling 8 bags of caramel corn.
If the measure of ∠2 is 83°, what is the measure of ∠3?
Answer:
97 degress
Step-by-step explanation:
2 and 3 form a supplementary angle, meaning the sum of their angles should equal 180.
The measure of ∠3 is 97°.
What are supplementary angles?If two angles add up to 180 degrees, they are considered supplementary angles. When combined, supplementary angles form a straight angle of 180 degrees. In other words, if Angle 1 + Angle 2 equals 180 degrees, angles 1 and 2 are added together. Angles 1 and 2 are referred to as "supplements" of one another in this instance.
Given two lines intersect and form angles
∠1, ∠2, ∠3, ∠4
and ∠2 = 83°
here ∠2 and ∠3 form supplementary angles,
them ∠2 + ∠3 = 180°
83 + ∠3 = 180
∠3 = 180 - 83
∠3 = 97°
Hence measure of ∠3 is 97°.

points (-6, 1) and (4, -4)?
A. 2
B. -2
C.1/2
D-1/2
I’m so confused help!!
Answer:
I think the answer would be -1/2 or D.
Step-by-step explanation:
Use this formula for calculating slope : y2-y1 / x2 - x1
1. label the pairs, 1 and 2
(-6, 1) - ( x1, y1 ) or (4,-4) - (x1, y1)
(4,-4) - ( x2, y2) (-6,1) - (x2, y2)
(the order does not matter)
2. Than plug in your numbers
y2-y1 / x2 -x1 y2-y1 / x2 -x1
-4 - 1 / 4 - (-6) or 1 - (-4) / -6 - 4
= -5/10 or -1/2 = - 5/-10 or -1/2

There are 20 students in Mrs. Williams' class, and 1/5 of the class has their own cellphone. Of this group of students, 1/2 of them are allowed to use social media. How many of the students have a
cellphone and can use social media?
Answer:
2
Step-by-step explanation:
Only 1/5 of Miss Williams' class has a cell phone, so we work this out by dividing the number of students by 5
20÷5=4
Out of this group of 4 students, only 1/2 are allowed to use social media
4÷2=2
This means that only 2 pupils have a phone and are allowed to use social media at the same time.
If you need to express this in fraction form, it would be 1/10 of the class
Let y^4+5x=11y 4 +5x=11y, start superscript, 4, end superscript, plus, 5, x, equals, 11. What is the value of \dfrac{d^2y}{dx^2} dx 2 d 2 y start fraction, d, squared, y, divided by, d, x, squared, end fraction at the point (2,1)(2,1)left parenthesis, 2, comma, 1, right parenthesis?
Answer:
[tex]\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]
Step-by-step explanation:
Given the expression [tex]y^4+5x=11y[/tex], we are to find the second derivative [tex]\frac{d^2y}{dx^2}[/tex]
This differentiation will be implicit (indirect) as shown:
[tex]4y^3 \frac{dy}{dx} + 5 = 11\frac{dy}{dx} \\4y^3 \frac{dy}{dx} - 11 \frac{dy}{dx} = -5\\\frac{dy}{dx}(4y^3-11) = -5\\\frac{dy}{dx} = \frac{-5}{4y^3-11}[/tex]
Differentiating the second time using quotient rule:
[tex]\frac{d^2y}{dx^2} = \frac{4y^3-11 (0)- (-5)12y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2\frac{dy}{dx} }{(4y^3-11)^2} \\\\\frac{d^2y}{dx^2} = \frac{60y^2(\frac{-5}{4y^3-11} ) }{(4y^3-11)^2}\\\\\frac{d^2y}{dx^2} = \frac{-300y^2}{(4y^3-11)^3}[/tex]

6(8-2x)=4x what is the answer to this equation?
Answer:
x=3
Step-by-step explanation:
6(8−2x)=4x
Step 1: Simplify both sides of the equation.
6(8−2x)=4x
(6)(8)+(6)(−2x)=4x(Distribute)
48+−12x=4x
−12x+48=4x
Step 2: Subtract 4x from both sides.
−12x+48−4x=4x−4x
−16x+48=0
Step 3: Subtract 48 from both sides.
−16x+48−48=0−48
−16x=−48
Step 4: Divide both sides by -16.
−16x/−16=−48/−16
Horizontal lines e and f are intersected by lines a and b. At the intersection of lines a and e, the uppercase left angle is 75 degrees. At the intersection of lines b and e, the uppercase right angle is 115 degrees. At the intersection of lines a and f, the bottom right angle is 75 degrees.
Which lines are parallel? Justify your answer.
Lines a and b are parallel because their alternate exterior angles are congruent.
Lines a and b are parallel because their same side exterior angles are supplementary.
Lines e and f are parallel because their alternate exterior angles are congruent.
Lines e and f are parallel because their same side exterior angles are congruent.

The ANOVA procedure is a statistical approach for determining whether or not a. the means of two samples are equal b. the means of more than two samples are equal c. the means of two or more samples are equal d. the means of two or more populations are equal
Answer:
d. the means of two or more populations are equal
Step-by-step explanation:
ANOVA is a short term for analysis of variance and it was developed by the notable statistician Ronald Fisher. It is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors. In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.
The ANOVA procedure is a statistical approach for determining whether or not the means of two or more populations are equal through the use of a F-test or null hypothesis.
The ANOVA procedure is a statistical approach for determining :
d. the means of two or more populations are equal
The ANOVA procedure is a statistical approach for determining the means of two or more populations are equal .

Let the missing angle be ∠y . Then :-
∠y =∠115°
Their measure will be equal as they are alternate interior angles whose angle measure will be equal when on two parallel lines with a transversal .
Therefore , the missing angle = 115° .
Solution (6) :Let the missing angle be ∠x . Then :-
∠x = ∠66°
Their measure will be equal as they alternate interior angles .
Therefore , the ,measure of the missing angle is = 66° .
Solution (7) :Let the missing angle be ∠m . Then :-
∠m + ∠50° = 180°
∠m = 180 - 50
∠m = 130°
The sum of these two angles will be equal to 180° as they are interior angles on the same side of transversal .
Therefore , the measure of the missing angle will be = 130° .
Solution (8) :Let the missing angle be ∠n . Then :-
∠n + ∠105° = 180°
∠n = 180 - 105
∠n = 75°
The sum of these two angles will be will be equal to 180° as they are interior angles on the same side of transversal .
Therefore , the measure of the missing angle will be = 75° .
Answer:
5) 115- alternate interior angles
6) 66 - alternate interior angles

please help !! write an expression that can be used to determine the total change
Answer:
y = 125x + 775
Step-by-step explanation:
you can make coordinate points (x, y) from the graph
x = Number of hours
y = Total Charge
(1, 800) and (2, 925)
slope from 2 points = y2-y1/x2-x1
x1 = 1
y1 = 800
x2 = 2
y2 = 925
925 - 800/2-1 = 125/1
m = 125
using y = mx + b, where m = 125, and 1 of the coordinate points you can find the y intercept
multiply 125 times 2
925 = 250 + b
subtract 250 from both sides
b = 675
y = 125x + 675

Which function has a zero with a multiplicity of 2?
Answer:p(x)=(x-1)(x-3)²
Step-by-step explanation:
The polynomial p(x)=(x-1)(x-3)² is a 3rd degree polynomial, but it has only 2 distinct zeros. This is because the zero x=3, which is related to the factor (x-3)², repeats twice. This is called multiplicity. It means that x=3 is a zero of multiplicity 2, and x=1 is a zero of multiplicity 1.

Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
Angle 7 and 6 are corresponding angles
you must find angle 7 becasue Angle 7= Angle 6
angle 7=x
138-x=180
