hope it helpsThe expression -22x + 3y = 6 in the form ax + by + c = 0 is -2x + 3y - 6 = 0
Linear EquationsThe given equation is:
-2x + 3y = 6
Comparing the equation above with ax + by + c = 0
Rewrite -2x + 3y = 6 in the form ax + by + c = 0
-2x + 3y - 6 = 0
If -2x + 3y - 6 = 0 is compared with ax + by + c = 0
a = -2, b = 3, c = -6
Therefore, the expression-22x + 3y = 6 in the form ax + by + c = 0 is -2x + 3y - 6 = 0

the length of a rectangle is 8 cm more than twice the width. the perimeter of the rectangle is 34 cm. what is the length of the rectangle
Answer:
14 cm
Step-by-step explanation:
let the length of the triangle be x and the width be y
x = 2y+8
2x + 2y = 34
2(2y + 8) + 2y = 34 (since x = 2y + 8)
6y + 16 = 34
6y = 18
y = 3
x = 2y + 8 = 2(3) + 8
x = 6 + 8
x = 14

Solve the system of equations
X=11+y
2x+y=19
Answer:
Step-by-step explanation:
To solve this system of equations, let's first find the value y. We can replace the x in the second equation with 11 + y, since we are told in the first equation that x is equal to 11 + y. So, let's replace x:
2(11 + y) + y = 19
22 + 2y + y = 19
22 + 3y = 19
3y = -3
y = -1
And look at that - we've found our y-value! Now, we can replace the y in the first equation with -1 to find the value of x.
x = 11 + (-1)
x = 10
So, the solution to this system of equations is (10, -1). Hopefully that's helpful!

Answer:
First triangle: 54.46 degrees
Step-by-step explanation:
For the first problem, solve for the third side, then the third angle, and then subtract from 180.
20^2 + 28^2 = c^2
400 + 784 = c^2
1184 = c^2
34.41 = third side
Find the third angle:
sin(90)/34.41 = sin(x)/20
20 * sin(90)/34.41 = sin(x)
35.54 is the third angle.
180 - 35.54 - 90 = 54.46. The angle with the question mark is 54.46. Do the other 2 problems the same way.

What is 87 x (495 - 475) + 1084 - 864
Answer:
1960
Step-by-step explanation:
First, carry out the operation inside the parentheses: 495-475= 20. Next, follow the order of operations and do 87*20= 1740. Then, go from left to right, adding 1740 + 1084= 2824. Now, subtract all of that by 864. 2824-864= 1960.

Answer:
19
Step-by-step explanation:
You had 6 dollars and your mom gave you 5. 6 + 5 = 11.
You dad gave you 8 dollars.
11 + 8 = 19
Answer:
19 dollars
Step-by-step explanation:
5+6+8=19
If you started off with 6 dollars and your mom gave you 5 you now have 11. If your dad gave you another 8 on top of the 11 you already had you now have 19.
A car travels 182 kilometers in 4 hours with the constant speed. how much time will it take traveling 42 kilometers
Answer:
55.38 min
Step-by-step explanation:
A car travels,
182 km ⇒ 4 hours
And we have to find the time that it takes to travel 42 km .
Lets make a equation.
Let the unknown time be x
182 km ⇒ 4 hours
42 km ⇒ x
To make easy let's km in to meters and hours in to minutes
182000 m ⇒ 240 min
42000m ⇒ x
Now use cross multiplication.
[tex]182000x=240*42000\\[/tex]
[tex]182000x=10080000[/tex]
[tex]\frac{182000x}{182000} =\frac{1008000}{182000}[/tex]

there are five bells which ring at interval of 4,5,12 and 15 minutes respectively at what minute those bells ring at the same time?
=====================================================
Explanation:
Let's find the LCM of 4 and 5, which are the first two items of the list.
multiples of 4 are: 4,8,12,16,20,24,...multiples of 5 are: 5,10,15,20,25,...The smallest item in each list is 20, so the LCM of 4 and 5 is 20.
We can replace the "4,5" in the list "4,5,12,15" with "20". So our new list would be "20,12,15".
We then repeat the process of finding the LCM of the first two items
multiples of 20 are: 20,40,60,80,...multiples of 12 are: 12,24,36,48,60,72,...LCM of 20 and 12 is 60.
The list "20,12,15" condenses to "60,15".
Repeat this process of finding the LCM once more and you'll find the overall LCM is 60.
Therefore, the LCM of the entire set {4,5,12,15} is 60. This is the smallest multiple shared by all four values. Interestingly enough, the outer values pair up to multiply to 60, and so do the inner values.
4*15 = 60
5*12 = 60
The bells ring together every 60 minutes
In other words, all of the bells ring together at the same time every hour (perhaps at the top of every hour; eg at 7:00 pm and at 8:00 pm, etc).

Hello there! :)
We are given the slope of the line: 1/10.We are also given the point that the line passes through.So, with the given information, we can use Point-Slope form:y-y1=m(x-x1)y-1=1/10(x-10)y-1=1/10x-1y=1/10xTherefore, that's the equation.Hope it helps. Use the comment section to clarify any doubts.

Good luck.
the equation of line which passes through point (10, 1) and having slope 1/10 is y = x/10 + 0.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
y = mx + b
In which the coefficients are described as follows:
• The coefficient m is the slope of the function, representing the rate of change of the function.
• The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).
Here, it is given that line passes though point (10,1) and having slope of 1/10.
Now, Let us find the equation of the line using point-slope equation of line :
(y-y₁) = m(x-x₁)
Substituting all the values in above equation to get the equation of line :
(y-1) = 1/10(x-10)
y - 1 = x/10 - 1
y = x/10 + 0
Therefore, the equation of line which passes through point (10, 1) and having slope 1/10 is y = x/10 + 0.

Solve for x the equation 6cos^2 x+4sin^2 x=5.Forex 2 question 6 cos square x + 4 sin square x is equal to 5
Step-by-step explanation:
[tex]6 \cos {}^{2} (x) + 4 \sin {}^{2} (x) = 5[/tex]
[tex]6(1 - sin {}^{2} x) + 4 \sin {}^{2} (x) = 5[/tex]
[tex]6 - 6 \sin {}^{2} (x) + 4 \sin {}^{2} (x) = 5[/tex]
[tex]6 - 2 \sin { }^{2} (x) = 5[/tex]
[tex] - 2 \sin {}^{2} (x) = - 1[/tex]
[tex] \sin {}^{2} (x) = \frac{1}{2} [/tex]
[tex] \sin(x) = \frac{1}{ \sqrt{2} } [/tex]
Take the arc Sine of the function
[tex]arcsin( \frac{1}{ \sqrt{2} } ) = \frac{\pi}{4} [/tex]
Finally, Sine is a periodic function so it has two answers within the interval (0, 2 pi)
Use the identity
[tex] \sin(x) = \sin(x + \pi) [/tex]
We know that
[tex] \sin( \frac{\pi}{4} ) = \frac{1}{ \sqrt{2} } [/tex]
so using the identity
[tex] \sin( \frac{\pi}{4} + \pi ) = \sin( \frac{5\pi}{4} ) [/tex]
So we have two answers.

x + 13 = 31
- 13 -13
x = 18
And there's the simple way of doing that I recmmend for this type of question which is:

For what value of k are the lines 2x + 3y = 4k and x - 2ky = 7 parallel?
Answer:
k = -3/4
Step-by-step explanation:
The lines will be parallel if their slopes are equal. To find the slope of each line, write its equation in slope-intercept form (y = mx + b). In other words, solve each equation for y and look at the coefficient of x.
2x + 3y = 4k
3y = -2x + 4k
y = (-2/3)x + 4k/3
The slope of the first line is -2/3.
x - 2ky = 7
-2ky = -x + 7
y = [1/(2k)]x - 7/(2k)
The slope of the second line is 1/(2k).
If the slopes are equal, then
1/(2k) = -2/3
Multiply by 2k.
1 = (-2/3)(2k) = (-4/3)k
1 = (-4/3)k
k = -3/4
