Answer:
Step-by-step explanation:
To graph the equation y-2=2/3(x+4), you can follow these steps:
Begin by isolating the y term on one side of the equation. To do this, you can add 2 to both sides of the equation:
y-2+2=2/3(x+4)+2
y=2/3(x+4)+2
Next, you can simplify the right side of the equation by multiplying 2/3 by (x+4):
y=2/3(x+4)+2
y=(2/3)x+(2/3)4+2
y=(2/3)x+8/3+2
y=(2/3)x+14/3
This is the standard form of the equation y=mx+b, where m is the slope and b is the y-intercept. In this case, the slope is m=2/3 and the y-intercept is b=14/3.
To graph the equation, you can use the slope and y-intercept to plot the first point on the graph. The y-intercept is the point where the graph crosses the y-axis, so you can plot the point (0,14/3) on the graph.
From this point, you can use the slope to find the next point on the graph. The slope is the change in y over the change in x, so you can use the slope to find the change in y and the change in x between two points on the graph. For example, you could choose a point that is 1 unit to the right of the y-intercept, or (1,0). The change in y between these two points is (14/3)-0=14/3 and the change in x is 1-0=1. Using the slope, you can find the y-coordinate of the next point on the graph:
y2=y1+m(x2-x1)
y2=14/3+2/3(1-0)
y2=14/3+2/3
y2=20/3
You can repeat this process to plot additional points on the graph. For example, you could choose a point that is 2 units to the right of the y-intercept
The sum of a number and twice its reciprocal is
9/2. If the number is an integer, find the number.
Answer:
x + 2/x = 9/2
multiply through by x
x2 + 2 = (9/2)x
multiply through by 2
2x2 + 4 = 9x
2x2 - 9x + 4 = 0
We can factor by grouping. 2(4) = 8 ...
taken from coefficient of square term and the constant ...
Factors of 8 that add to -9 are (-8)(-1):
Replace -9x with -8x - x
2x2 - 8x - x + 4 = 0
(2x2 - 8x) - (x - 4) = 0
2x(x - 4) - (x-4) = 0
(2x-1)(x-4) = 0
2x-1 = 0 and x = 1/2
OR
x-4 = 0 and x = 4
Your two answers are {1/2, 4}

Step-by-step explanation:
We need to integrate the given expression. Let I be the answer .
[tex]\implies\displaystyle I = \int (cos(3x) + 3sin(x) )dx \\\\\implies\displaystyle I = \int cos(3x) + \int sin(x)\ dx [/tex]

Two hockey teams, the Winnipeg Jets (yay!) and the Toronto Maple Leafs (boo!), miraculously make it to
the Stanley Cup finals. As soon as a team wins 3 games, the championship is over.
The schedule for the playoffs (for home games) is: Jets - Leafs - Jets - Leafs - Jets
If the Jets are playing at home, there is a 60% chance they'll win. If they are playing on the road, there is
a 45% chance they'll win.
Find the probability that the Jets win the Stanley Cup. Round answers to at least 4 decimal places.
Can anyone help me. answer with full explanation. No links please
Answer:
There is a 54% chance that the Jets will win the Stanley Cup.
Step-by-step explanation:
Since two hockey teams, the Winnipeg Jets and the Toronto Maple Leafs, miraculously make it to the Stanley Cup finals, where as soon as a team wins 3 games, the championship is over, and the schedule for the playoffs for home games is: Jets - Leafs - Jets - Leafs - Jets; since if the Jets are playing at home, there is a 60% chance they'll win, while if they are playing on the road, there is a 45% chance they'll win, to find the probability that the Jets win the Stanley Cup the following calculation must be performed:
(0.60 + 0.45 + 0.60 + 0.45 + 0.60) / 5 = X
2.70 / 5 = X
0.54 = X
Thus, there is a 54% chance that the Jets will win the Stanley Cup.

Help! Quick! Find the area of the composite figure
Answer:
60m
Step-by-step explanation:
To find the area of the triangle you multiply the base by height and divide by two, but we don’t know the base of the triangle!
Luckily, the bottom of the triangle is a rectangle. Rectangles are symmetrical, and the other side of the rectangle is 8.
So, the base of the triangle is 8.
Now let’s find the area of the triangle:
8 x 5 = 40
40/2 = 20
20 is the area of the triangle
Now, we must find the area of the rectangle!
The formula for rectangle area is just width x length:
8 x 5 = 40
Add them together:
40 + 20 = 60
Therefore, the area is 60m.

Write a system of linear equations.Write two-variable equations in slope-intercept form.
Answer:
A linear relation can be written in the slope-intercept form as:
y = a*x + b
Where a is the slope, and b is the y-intercept.
And if a line passes through the points (x₁, y₁) and (x₂, y₂), the slope can be written as:
a = (y₂ - y₁)/(x₂ - x₁)
Now let's look at our lines.
The left one passes through the points (0, -3) and (-2, 0)
Then the slope of this line is:
a = (0 - (-3))/(-2 - 0) = 3/-2 = -(3/2)
Then the line will be something like:
y = -(3/2)*x + b
Knowing that this line passes through the point (0, -3), we know that when x = 0, we must have y = -3
Then:
-3 = (-3/2)*0 + b
-3 = b
So the first linear equation is:
y = -(3/2)*x - 3
Now let's look at the second line, this one passes through the points (0, 2) and (1, 0)
Then the slope of this line is:
a = (0 - 2)/(1 - 0) = -2
And we can write the line as:
y = -2*x + b
Knowing that this line passes through the point (0, 2), we know that when x = 0 we must have y = 0, replacing that we get:
2 = -2*0 + b
2 = b
Then the equation of this line is:
y = -2*x + 2
Now that we know both equations we can write our system as:
y = (-3/2)*x - 3
y = -2*x + 2
To solve it, we need to remember that y = y
then:
(-3/2)*x - 3 = y = -2*x + 2
(-3/2)*x - 3 = -2*x + 2
We can solve this for x.
2*x - (3/2)*x = 2 + 3
(1/2)*x = 5
x = 5((1/2) = 5*2 = 10
And to find the y-value, we need to input this x-value in one of the equations:
y = -2*10 + 2 = -20 + 2 = -18
Then the solution of the system is the point (10, -18)

The yield of a certain chemical reaction is believed to be related to temperature. A study collected the yield from 15 such reactions selected at random to test the belief and producedthe following results.
Variable Estimate
Intercept 1 15.5 2.96
Temp 1 0.05 0.017
R-sq = 0.73
Which of the following is the appropriate test statistic for the test?
a. t=0.05/0.73
b. t=15.5/0.73
c. t=0.05/15.5
d. t=15.5/0.05
Answer:
t = 0.05 / 0.017
Step-by-step explanation:
Given the table :
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
The test statistic for a regression test :
t = b1 / E
Where ;
b1 = slope ; E = Standard error of the slope
From the result table ;
b1 = 0.05 ;
E = 0.017
The test statistic, t = 0.05 / 0.017
The appropriate test statistic for the test is t = 0.05 / 0.017.
Calculation of the test statistic for the test:Since
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
So here the test statistic should be
t = b1 / E
here,
b1 = slope ;
E = Standard error of the slope
So,
The test statistic, t = 0.05 / 0.017

LC is 40°. What is the measure of arc CB?
I hope this helps you
Hi there!
[tex]\large\boxed{100^{o}}[/tex]
∠C = 40° and triangle ABC is isosceles, therefore:
∠C = ∠A = 40°
Angles in a triangle sum up to 180°, so:
180 = 40 + 40 + ∠A
180 = 80 + ∠A
100 = ∠A
Thus, arc CB has a measure of 100°.

First you must understand that in geometry, the alternate interior angles are equal
Hence if ∠3 and ∠6 are alternate interior angles, then <3 = <6
Given that m<3 = 75 degrees
m<6 will also be 75 degrees since both angles are equal
