Answer:
m = [tex]\frac{2}{3}[/tex] , b = - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Given
2x - 3y = 6 ( subtract 2x from both sides )
- 3y = - 2x + 6 ( divide all terms by - 3 )
y = [tex]\frac{2}{3}[/tex] x - 2 ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex] and y- intercept b = - 2
Answer:
y- intercept is (0, -2)
slope is 2/3
Step-by-step explanation:
find 2 points on the line:
2x-3y=6
1/2*(6+3y) =x
if y is 2, x is 6 ((6,2))
if y is 4, x is 9 ((9, 4))
y-intercept is when x = 0.
0-3y=6
y=-2
slope is (y2-y1)/(x2-x1): choose y2 and the corresponding x-coordinate is x2. then the others are the 1's. let's use 4 as y2 which means:
x2 = 9
x1 = 6
y1 = 2
then plug in and solve.
(4-2)/(9-6)
= 2/3
m = 2/3
Hope this helps!

Ava takes 4 breaths every 10 seconds during yoga. At this rate, how many breaths would Ava take in two minutes? *
Answer:
48
Step-by-step explanation:
It's given that Ava takes 4 breaths every 10 seconds.
4 breaths : 10 seconds. ...(1)
To solve this, first we need to calculate how many seconds there are in two minutes.
As 60 seconds make up one minute, 120 seconds make up two.
Now, to solve for the number of breaths (x), we just multiply (1) by 12. We do this so that we get 120 seconds on the right side, so the left side will give us the answer we need.
4 × 12 breaths : 10 × 12 seconds
48 breaths : 120 seconds.
So, the final answer would be 48 breaths.

Which compound inequalitiy represents the inequality |y – 3| − 4 ≤ −3?
a.) −1 ≤ y – 3 OR y – 3 ≤ 1
b.) y – 3 ≤ −1 AND y – 3 ≥ 1
c.) −1 ≤ y – 3 AND y – 3 ≤ 1
d.) y – 3 ≤ −1 OR y – 3 ≥ 1
The compound inequality represents the given inequality is y-3≤1 OR -1≤y-3. Therefore, option A is the correct answer.
The given inequality is |y – 3| − 4 ≤ −3.
What is compound inequality?A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time. It is the overlap or intersection of the solution sets for the individual statements. “Or” indicates that, as long as either statement is true, the entire compound sentence is true. It is the combination or union of the solution sets for the individual statements.
Now, solve inequality |y – 3| − 4 ≤ −3.
Add 4 on both sides of the inequality.
That is, |y – 3| − 4+4 ≤ −3+4
y-3≤1 OR -1≤y-3
The compound inequality represents the given inequality is y-3≤1 OR -1≤y-3. Therefore, option A is the correct answer.

if you have 30 N force going left and a 10 N force going right, what is the force
Answer:
20 N
Step-by-step explanation:
Since, both the forces are acting in opposite directions.
Therefore,
[tex]Net \: Force = 30 \: N - 10 \: N \\ \\ = 20 \: N [/tex]
Answer:
20N
Step-by-step explanation:If you take the direction that the 30N force is acting in as positive, then since the 10N force acts in the opposite direction, the Net (resultant) force on the object is 20N. If the numbers were flipped, it would be -20N.

The 2018 Current Population Survey (CPS) estimates that 19.7% of Mississippians live in poverty, which makes Mississippi the state with the highest poverty rate in the United States. If we take a random sample of 250 Mississippians, what is the probability that at least 25% of them live in poverty?
Answer: 0.0265
Step-by-step explanation:
Given: The proportion of Mississippians live in poverty, which makes Mississippi the state with the highest poverty rate in the United States. : p = 19.7% = 0.197
Sample size : n= 250
The probability that at least 25% of them live in poverty will be
[tex]P(\hat{p}\geq0.25)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\geq\dfrac{0.25-0.197}{\sqrt{\dfrac{0.25\times0.75}{250}}})\\\\=P(Z>\geq1.9353)\\\\=1-P(Z<1.935)\\\\=1-0.9735\ \ \ \ [\text{By p-value table}]\\\\=0.0265[/tex]

PLS HELP ME! I GOT THE ANSWER I JUST NEED TO SHOW THE WORK.
Solve for X.
Answer: 6
Answer: x = 6
=================================================
Work Shown:
According to the remote interior angle theorem, we can add the interior angles to get the exterior angle that is not adjacent to the interior angles.
So we'll add interior angles D = 6x+8 and E = 5x+8, and that sum leads to 82.
Let's solve for x
(6x+8)+(5x+8) = 82
11x+16 = 82
11x = 82-16 ....... subtracting 16 from both sides
11x = 66
x = 66/11 ...... dividing both sides by 11
x = 6
-----------------
A slightly longer method involves letting y be the missing interior angle of triangle DEC.
Then we can say D+E+C = (6x+8)+(5x+8)+y = 180. This is because the interior angles of any triangle always add to 180.
Furthermore, we also know y+82 = 180, since the angles y and 82 are a linear pair. Solving for y leads to y = 180-82 = 98
Plug this back into the first equation and solve for x
(6x+8)+(5x+8)+y = 180
(6x+8)+(5x+8)+98 = 180
(6x+8)+(5x+8)= 180-98
(6x+8)+(5x+8) = 82 .... note how this equation shows up again
The steps to solving are shown in the previous section.

Given that for all values of x,
f(x) = 3x + p
g(x) = px + 4
and fg(x) = 6x + 9
where p and q are constants.
Work out the values of p and q.
The value of p is 2.
The value of q is 14
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Two functions:
f(x) = 3x + p
g(x) = px + 4
Now,
f(g(x)) = 6x + 9
This means,
3(g(x)) + p = 6x + q
Substituting g(x) = px + 4.
3(px + 4) + p = 6x + q
3px + 12 + p = 6x + q
3px + (p - q) = 6x - 12
This means,
3p = 6
p = 2
p - q = -12
2 - q = -12
q = 2 + 12
q = 14
Thus,
p is 2 and q is 14.
