Answer:
The y-intercept is 3.
Step-by-step explanation:
Step 1: Find the slope of the line.
m = rise/run = y2 - y1/ x2 - x1
m= 9-(-1)/-3-2
m=10/-5 = -2
Slope-intercept form equation is y = mx + b
Step 2: Plug in slope to slope-intercept equation and solve for b (y-intercept)
y = -2x + b
We can use the point (2, -1)
Plug it in.
-1 = -4 + b
Solve.
b = 3

Find the value of x and the value of y.
Answers
Answer:
B.
Step-by-step explanation:
If you extend the middle line, you will find that the two angles that the line makes are 60° and 40° by alternate interior angles.
Then, you can just make an equation:
2x + 2x - y + y + 60 + 40 = 360
4x = 260
x = 65°
Now you can use same side interior angles to make another equation:
2x - y + 60 = 180
130 + 60 - y = 180
y = 10

Write an equation of the line that passes through (−1, 3) and is perpendicular to the line y=1/9x−1.
Answers
Answer:
Step-by-step explanation:
General equation of line
y = mx + c
m is slope
y = (1/9)x - 1
1/9 is slope
Since the other line that passes through the point is perpendicular, the product of both slopes is -1
1/9 * m = -1
m = -9
Using point-slope method
y-y1 = m(x-x1)
y-3 = -9(x-(-1))
y-3 = -9(x + 1)
y-3 = -9x -9
y = -9x-6

To find: the expression whose value is closest to e
Solution:
Value of e is 2.718
[tex]\left ( 1+\frac{1}{19} \right )^{19}=\left ( \frac{20}{19} \right )^{19}=2.65\\\left ( 1+\frac{1}{22} \right )^{22}=\left ( \frac{23}{22} \right )^{22}=2.659\\\left ( 1+\frac{1}{20} \right )^{20}=\left ( \frac{21}{20} \right )^{20}=2.653\\\left ( 1+\frac{1}{21} \right )^{21}=\left ( \frac{22}{21} \right )^{21}=2.656[/tex]
Therefore, value 2.659 is closest to the value of e.

Anna takes 2 minutes to perform each exercise of her workout routine at the gym. She has already been at the gym for 20 minutes and wishes to be there no longer than 1 hour in total. Anna wonders if she has time to do 18 more exercises.
(1.) Write an inequality to find the maximum number of exercises x Anna can perform without leaving the gym later than she planned.
(2.) Does Anna have time to do 18 more exercises. Explain.
Answers
Answer:
1. 20 + 2x ≤ 60
2. Yes, see explanation
Step-by-step explanation:
Let x equal the amount of exercises Anna can perform.
The inequality will look like this:
20 + 2x ≤ 60
Let's go over each of the values and why there in the equation.
20: The amount of minutes Anna has already spent in the gym
2: The amount of minutes per exercise
x: The amount of exercises Anna can perform
≤: The amount of exercises must be less than or equal to the amount of time Anna is willing to spend in the gym.
60: The amount of minutes in an hour; the amount of time Anna is willing to spend at the gym.
Now, plug in 18 for x for question 2.
20 + 2(18) ≤ 60
Evaluating 2*18, the inequality becomes 20 + 36 ≤ 60.
Evaluating 20 + 36, the inequality becomes 56 ≤ 60.
Since 56 is less than 60, we can determine that Anna has time to do 18 more exercises.

The length of a planet's orbit around a star is approximately 17,650,000 km.
It takes the planet about 640 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answers
Answer:
1150 km/hr
Step-by-step explanation:
Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours
In the question we are given the following parameters.
The length of a planet's orbit around a star = Distance = 17,650,000 km.
Time taken to complete a full orbit = 640 Earth days
Step 1
We need to convert the time in days to hours
1 Earth day = 24 hours
640 Earth days =
We cross multiply
640 Earth days × 24 hours
= 15360 hours.
Step 2
Average Speed = Distance in Kilometers/ Time in Hours
Average Speed = 17,650,000 km. /15360 hours
Average Speed = 1149.0885417 km/hr
Approximately to 3 significant figures=
1150 km/hr
Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr

T
n = 8
n = 11
n = 16
Answers
Answer:
n=11
Step-by-step explanation:
n+1=4(n-8)
11+1=4(11-8)
12=4(3)
12=12
question:
n+1= 4(n-8)
first step: distribute 4 through the parenthesis:
n+1= 4n-32
next step: move the variable to the left hand side and change the sign:
n-4n+1= -32
next step: collect the like terms:
-3n= -32-1
last step: divide both sides by -3:
-3n= -33
solution: n= 11

Find the value of x and y
Answers
Answer:
x = 2, y = 29
Step-by-step explanation:
3y+19 = 106
3y = 106-19
3y = 87
y = 87/3
y = 29
2x+9 = x+11
2x-x = 11-9
x = 2
Answer:
x = 2
y = 29
Step-by-step explanation:
2x + 9 and x + 11 are sides that are congruent to one another, so set them equal, like so:
2x + 9 = x + 11
Subtract x from both sides:
x + 9 = 11
Subtract 9 from both sides:
x = 2
Solving for y, the opposite angles are congruent to one another, so set them equal, like so:
3y + 19 = 106
Subtract 19 from both sides:
3y = 87
Divide both sides by 3:
y = 29

Answers
Answer:

Step-by-step explanation:
Answer:
The length of rectangle is 3x.
Step-by-step explanation:
Given that the perimeter of rectangle formula is P = 2l + 2w where l represents length and w is width. Then you have to substitute the expressions into the formula :
[tex]p = 2l + 2w[/tex]
Let p = 8x - 2,
Let w = x - 1,
[tex]8x - 2 = 2l + 2(x - 1)[/tex]
[tex]8x - 2 = 2l + 2x - 2[/tex]
Next you have to find the expression for length by moving all the unrelated terms to the other side :
[tex]8x - 2 - 2x + 2 = 2l[/tex]
[tex]2l = 6x[/tex]
[tex]l = 3x[/tex]
Which graph represents the function f(x) =1/3 |x|?
Answers
Step-by-step explanation:
f(x) = 1/3|x|
then
f(x) = 1/3x , if x ≥ 0
and
f(x) = -1/3x , if x ≤ 0
the slope of f(x) = 1/3x is 1/3
the slope of f(x) = -1/3x is -1/3
this two above conditions apply on to the fourth graph to the right.
Megan has a bag containing 5 pink marbles, 3 orange marbles, 6 green marbles, and 2 yellow marbles.
Megan started to develop a probability model. Here is the sample space.

Part A
put in order where it would go on the table 2/16, 3/16, 5/16, 6/16
Help Megan complete the model by assigning probabilities to the four listed events. Drag each fraction to the correct probability.
Part B
Suppose Megan drew a marble 80 times. Estimate how many times she should expect to draw an orange marble. Megan would draw an orange marble ____
times.
Answers
Step-by-step explanation:
To find the probability
Total marbles = 5 + 3 + 6 + 2 = 16
P pink = 5/ 16
P orange = 3/16
P green = 6/ 16 = 3/8
P yellow = 2/16 = 1/8
Part B when we divide 80 by 16 = 5
So she drew every marble 5 times
So 3 x 5 = 15
She drew the orange marble 15 times
