Answer:
the y intercept is where is starts (up and down) slope is how much you run up, or down and how much you run
Step-by-step explanation:
For example the third croses at 5 thats the y-intercept. Know notice how you go up once and run two blocks for the slope. So the slope is 1/2x.
Answer for #3 y=1/2x+5
Note. Anytime you are running down the slope will be negative. If the line points up then its positive.
Answers should be in this form: 1) positive 2. negative 3. positive 4. negative 5. positive 6. negative
Answer:
1. slope = 4 over 2(2), y int = -8
2. slope = 2 over 3 , y int = 2
3. slope = 3 over 6(1/2), y int = 5
4. slope = 1 over 3, y int = -3
5. slope = 3 over 3(1) ,y int = 0
6. slope = 2 over 3 ,y int = -4
Step-by-step explanation:
The numbers in the () is the simplified slope version if there is no () it cannot be simplified

Can you find the slope-intercept of the line? Thank you!
Answers
Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = [tex]\frac{2-0}{0+2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = x + 2 ← equation of line

Answers
Answer:
4/24
Step-by-step explanation:
Because 1/6 is 4/24 simplified.
To prove this, all you have to do is try simplifying 4/24 yourself. To do that, we are going to use 4 to divide both the numerator and the denominator because 4 is a common factor of 4 and 24.
(To simplify a fraction, you divide both the numerator and denominator by a common factor)
So 4 divided by 4 is 1, and 24 divided by 4 is 6

Hi again I need a story that matches the equation -6 + 3x = 2 + 4x
Answers
Answer:
A.
Step-by-step explanation:
The required stories that are models of the given expression -6 + 3x = 2 + 4x are given in A and B. Both options are correct.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Option A,
At 5 p.m., the temperatures recorded at two weather stations in Antarctica are -6 degrees and 2 degrees. The temperature changes at the same constant rate, x degrees per hour, throughout the night at both locations. The temperature at the first station 3 hours after this recording is the same as the temperature at the second station 4 hours after this recording.
So from the above statement,
The equation modeled is given as
-6 + 3x = 2 + 4x
The above expression is equivalent to the given statement. So story mentioned in option A matches the given equation.
Similarly,
The equation formed in Option B also matches the given equation.

Find the center and radius of the equation of the circle
a). x2 + y2 – 8x +6y + 9 = 0
Answers
Compare the given equation with the general equation of a circle
Given equation: x² + y² - 8x +6y +9 = 0
Equation of a circle: x² + y² + 2gx + 2fy + c = 0
2g= -8; g = -8÷2= -4
2f = 6; f = 6÷2 = 3
c= 9
Solving for radius of the circle...
r =√g² + f² - c
g= -4, g² = ±16
f = 3, f² = 9
Substituting, we have
r = √16 + 9 - 9
r = √25-9
r=√16
r = 4
Therefore, the centre and radius of the circle is 9 and 4 respectively.

I would assume that the angle of f equals 50°... sincesince the triangles are similar that means that the angles are most likely equal to each other. since the big triangle you can do it 90 + 40 which equals 130 then 180, since that is the total degrees in a triangle, minus 130 equals 50 this means 50 ° is the angle of c. keep in mind angle c equals angle f.
An EPA contractor needs to test the concentration of a substance in ten samples of the ground water. Seventy samples were

Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results
There were 400 sweets in a pack. The principal of a school bought 25 such packs of sweets for 2000 children o Children's Day. If each child was given 7 sweets, how many more packs of sweets were needed?
Answers
Answer:
10 more packs
Step-by-step explanation:
400 sweets bought 25 such packs = 400*25=10000
2000 each one gets 7 = 2000*7=14000
14000-10000=4000
4000/400 is 10.
So 10 more packs.
Hit the crown :D
Answer:
Step-by-step explanation:
400 sweets in a pack * 25 packs = 10,000 sweets
2000 kids * 7 sweets = 14,000
We need 4,000 more sweets. That would be 10 packs more since there are 400 sweets in a pack.

Step-by-step explanation:
Given that:
Video length of all 3 friend are equal
Let the length of the video made by each friend = s
Length of video of all 3 friends = 3s
Alicia's video segment is less than 5 minutes long
Hence the length L of the full video :
L = (Length of video of all 3 friends + Alicia's video segment)

If pqrs is a parallelogram, find the measure of

Answers
Answer:
∠PSR = 113°
Step-by-step explanation:
Two angles in a parallelogram that are next to each other are supplementary. That means that they add up to 180°, so 7x-13+4x-5 = 180. Solve for x.
7x-13+4x-5=180
11x-18=180
11x=198
x=18
Now plug x back into the angle that opposite from the one you are looking for (they are equal)
7(18)-13 = ∠PSR
126-13 = ∠PSR
113 = ∠PSR
