I need help finding the y-intercept of these, I am no good with slope and tables. ;-;
Answer:
1. -4
2. 6
3. -6
(i hope this is right •_•)
Step-by-step explanation:
First table
When the x coordinate is 0, that point is your y intercept. For the first one, your y intercept is -4.
Second table
For the second one, we need to do a bit of counting. We can see the x coordinates go before and after zero, but the table does not show us 0. So, we're going to have to calculate the slope. Bear with me here, I'm a little tired and this might be rambling ;-;
So, the formula for calculating slope is [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. I'm going to use those first two points to get my slope. We're going to say the first point is point 1 and the second point is point 2 (genius, i know lol). So, let's substitute in the x and y values.
[tex]\frac{9-12}{-3-(-6)}[/tex]
And simplify...
[tex]\frac{-3}{3}[/tex]
So, your slope is -1. We can use that. We just have to count down.
If the x is -2, the y is 8. If the x is -1, the y is 7. And if the x is 0....(drumroll please) the y is 6! So, your y intercept is 6.
Third table
Now, this table isn't very nice either and doesn't have an x as 0 for us. Hmpf. But we can still do what we did above. I'll just skip the explanation and you can observe my steps.
[tex]\frac{-3-(-5)}{9-3}[/tex]
[tex]\frac{2}{6}[/tex]
[tex]\frac{1}{3}[/tex]
Let's count down....
If x = 3, y = -5
If x = 2, y = -5 1/3
If x = 1, y = -5 2/3
If x = 0, y = -6
A. y+x=-3
B. y=3x+1
C. y-3x=1
D. y=3x+1

Find the value of x in the triangle shown below
Answer:
x= 80°
Step-by-step explanation:
An isosceles triangle has two equal sides and two equal angles; so 50° + 50° = 100
then you have to subtract 100° from 180° and you'll get 80°

Use finite differences to identify the degree of the polynomial that best describes the data.
Answer:
cubic
Step-by-step explanation:
The degree of the polynomial that best describes the data is quadratic.
What is Polynomials?Polynomials are kind of algebraic expressions consisting of variables, constants and coefficients along with exponents consisting of finite number of terms.
There are different types of polynomials like linear, quadratic, cubic and so on depending on the highest degree of the variables.
Finite difference method is used to find the degree of the polynomial by finding the difference of the values corresponding to the the values of the independent variable which are equally spaced.
Here, x is the independent variable and the values of x are given.
We have,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
Find the first finite difference of the y values, we get,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
First finite difference : 2 -5 -12 -19 -26
This is not constant.
Second finite difference : -7 -7 -7 -7
Second finite difference is constant.
So this is a polynomial equation of degree 2.
Hence the given polynomial is quadratic.

6. Priya and Jax are 20 miles apart in a path when they start walking towards each other. Priya
runs at a constant speed of 6 miles an hour and Jada walks at a constant speed of 2 miles an
hour. How long does it take for them to meet? Explain your reasoning,
Answer:
2 hours 30 minutes
Step-by-step explanation:
Step one
Given data
The total distance to be covered= 20miles
Priya runs at a constant speed of 6 miles an hour
Hence Her speed = 6mph
Jada walks at a constant speed of 2 miles an hour
Hence Her speed = 2mph
let the time taken by them to cover the distance be t
Step two:
from speeed= distance/time
distance= speed*time
so
20=6*t+2*t
20= 6t+2t
20=8t
divide both sides by 8
t= 20/8
t=2.5 hours
That is, it wiil take them 2 hours 30 minutes to meet
The reason is because, the distances covered by them must sum up to 20 miles

Introduction (Kinda)
So you want to write the equation and find the number.
Writing the Equation
Well, the question says "A number s is subtracted from seven. When the result is divided by three, the quotient is two."
If a number s is being subtracted from seven.
7-s
When the result of 7-s is divided by three, the quotient is two. Since your effecting the result of 7-s, you have to put those in parentheses.
(7-s)
Your dividing 7-s by 3.
(7-s) / 3
When you do that, you get 2.
(7-s) / 3 = 2
This is the equation.
Finding the Number
Now you need to solve the equation.
(7-s) / 3 = 2
You need to isolate the s. "Remove" the numbers in opposite PEMDAS order...
Addition and Subtraction
Multiplication and Division
Exponents
Parentheses
7-s is in parentheses.
Divided by 3 is division. So you do that first.
You can multiply by 3 to cancel that out.
(7-s) / 3 × 3 = (7-s)
2 × 3 = 6
7-s = 6
Now that 7-s is on its own side, you can remove the parentheses.
So now to cancel the 7, you subtract 7 from each side (of the equation).
7-s-7 = -s
6-7 = -1
-s = -1
Now to cancel the negative signs, multiply each side by -1.
-s × -1 = s
-1 × -1 = 1
s = 1
Final Answer
The equation is...
(7-s) / 3 = 2
The number is...

the coordinates of point A(-3,2) and the coordinates of point B(4,1) what is the length of AB?
9514 1404 393
Answer:
AB = 5√2
Step-by-step explanation:
The length of AB is given by the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((4 -(-3))² +(1 -2)²) = √(7² +(-1)²) = √(49 +1) = √50
The length of AB is √50 = 5√2.
