2x+2y=-6 what is it solved into a y=Mx+b
The equation 2x + 2y = -6 in the form of y = mx + b is y = -x - 3.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
2x + 2y = -6
Subtract 2x on both sides.
2y = -6 - 2x
Divide both sides by 2.
y = -3 - x
y = -x - 3
This is in the form of y = mx + b
Now,
m = -1 and b = -3.
Thus,
y = -x - 3 is the equation.

Joshua is going to invest $490 and leave it in an account for 5 years. Assuming the interest is compounded continuously, what interest rate, to the nearest tenth of a percent, would be required in order for Joshua to end up with $620?
Answer: 4.7%
Step-by-step explanation:
A=Pe^rt
A=620. P=490. t=5
620 = 490e^r(5)
620/490 = 490e^5r/490
1.2653061 = e^5r
In(1.2653061) = In(e^5r)
In (1.2653061)/5 = 5r/5
0.0470628 = r
4.70628% = r

Answer: C = 12
Step-by-step explanation:
A = x
B = x[tex]\sqrt{3}[/tex]
C = 2x
So then to find A we divide B by [tex]\sqrt{3}[/tex], which makes A =6. But C = 2x, so then C = 2(6), which equals 12. Hope that helps :)

What is Proportionality?When two quantities have some dependence in their values they can be said proportional to each other.
It can be of two types such as direct and indirect.
The direct proportionality means the values of both the quantities are increasing or decreasing at the same time while the indirect proportionality implies value of one quantity is increasing while the other is decreasing.
The table for the given case can be written as follows,
Packages of Golf Balls Cost
1 $15
2 $30
3 $45
4 $60
The relation for proportionality can be obtained as,
15/1 = 30/2 = 45/3 = 60/4 = 15
(A) Suppose n be the number of packages.
Then, the cost is given as 15n.
(B) The cost of 7 packages is as below,
⇒ 15 × 7 = $105
Hence, the answers to both part can be given as 15n and $105 respectively.

Is NP an undecidable problem?
Therefore , the solution of the given problem of NP-complete problem comes out to be that every NP problem is decidable.
Define NP-complete problem.Nondeterministic polynomial-time complete is referred to as "NP-complete" in short. In this nomenclature, the phrase "nondeterministic" refers to stochastic Turing machines, a technique of theoretically formalizing the concept of a brute-force search process.
Here,
Consider that each NP problem can be resolved.
This is a crucial idea.
Since P problems also fall under the concept of NP, it is possible that P vs. NP may not be dependent on established formal frameworks like ZF set theory (i.e., neither provable nor disprovable in them).
Certain NP-Hard issues can also be found in NP.
It follows that any NP problem is decidable as the answer to the given NP problem.
Therefore , the solution of the given problem of NP-complete problem comes out to be that every NP problem is decidable.

A man bought an item for N5000.00 and sold it at a loss of 25%. How much did he sell it? A. N6250.00 B.N4750.00 C.N3750.00
D. N2250.00
Answer: B. 3750
Step-by-step explanation:
We start by converting the percentage 25% to the decimal 0.25.
Next, we multiply the original price by this decimal (5000*0.25=1250)
And Finally, Since it is a loss we subtract the 1250 from the original price.
5000 - 1250 = 3750

A principal randomly chose 40 students from grade 7. Of these students, 9 were wearing watches. Based on this information, what is the most reasonable prediction of the number of students wearing watches in a group of 480 students from grade 7?
Answer:
108 students
Step-by-step explanation:
We can just multiply each value by a k value, or a constant of variation, since we would expect them to be proportional. To find it, we take our two known variables and divide them. 480/40 = 12. Now we multiply that number by 9 to find the projected amount of students wearing watches in the whole grade. 12*9 = 108.

Find the value of x in the diagram at the right.
Show your work.
In the given diagram beside a coffee, the value of x is 38.
What is diagram?A diagram is a visual, symbolic representation of data. Diagrams have been used on cave walls since prehistoric times, but they became more common during the Enlightenment. The method occasionally employs the projection of a three-dimensional visualisation onto a two-dimensional surface. Sometimes the word "graph" is used in place of the word "diagram."
We know that all angles here add up to 360°
And with the vertical angles theorem we get the equation
2(36°) + 2(78 - x)° + 2(3x - 10) = 360°
2(36 + 78 - x + 3x - 10) = 360°
2(104 + 2x) = 360°
208 + 4x = 360°
4x = 360 - 208
4x = 152
x = 152/4
x = 38
Thus, In the given diagram beside a coffee, the value of x is 38.

Write 5 2/3+2 1/5 as a mixed number
Answer: 7 13/15
Step-by-step explanation:
First of, you have to get your common denominator, as it's impossible without one.
The closest common denominator is 15, and it will ask you for a simplified version.
Multiply the 2/3 in 5 2/3 by 5 on both sides to get 5 10/15
Multiply the 1/5 in 2 1/5 by 3 on both sides to get 2 3/15
Then add up your sum.
5 10/15+2 3/15=7 13/15
Answer:
7 13/15
Step-by-step explanation:
5 2/3+2 1/5
We need to get a common denominator for the fraction
3*5 = 15
2/3 *5/5 = 10/15
1/5 * 3/3 = 3/15
5 10/15 + 2 3/15 = 7 13/15

The cylinder can be "unwrapped" into a rectangle, to get a stripe that is a parallelogram with base 3 and height 80.
However, I don't understand how the height of the stripe can be eighty. The distance from the top of the cylinder to the bottom is 80 feet as given, so how can a winded stripe that goes around be also 80 feet?
