Brillianst!!! please!!!
The solution to the system of equations is:
x = 2/3 and y = 14/3
We have,
Since both equations are equal to y, we can set them equal to each other and solve for x:
4x + 2 = -2x + 6
Adding 2x and subtracting 2 from both sides, we get:
6x = 4
Dividing both sides by 6, we get:
x = 2/3
Now that we have a value for x, we can substitute it into either equation to find the corresponding value of y.
Let's use the first equation:
y = 4x + 2
y = 4(2/3) + 2
y = 8/3 + 2
y = 14/3
Therefore,
The solution to the system of equations is:
x = 2/3 and y = 14/3

Answer:
6.6
Step-by-step explanation:
I just did this :)
The interest rate annually will be 6.6% for the given compound interest will be 6.6%.
What is compound interest?
Compound interest is applicable when there will be a change in principal amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount.
As per the given,
Principle amount P = $2100
Time period T = 14 years
The annual rate of interest is R
Total investment = $5300
Number of times interest applied per time period n = 12
By compound interest formula,
5300 = 2100[1 + R/(100)]^(12 x 14)
(1 + R/1200)¹⁶⁸ = 5.524
1 + R/1200 = 5.51 x 10⁻³
R = 6.6% annually
Hence "The interest rate annually will be 6.6% for the given compound interest will be 6.6%".

If x = 3, y = 4 and z = -2, then 5x - 2y - z =
Answer:
9
Step-by-step explanation:
Hey There!
So for this problem all we have to do is plug in the given values into the expression so now we have
5(3) - 2(4) - -2
5x3=15
-2x4=-8
now we have
15-8-(-2)
15-8=7
7-(-2)
remember when you subtract a negative number the two negative signs cancel out and turn into a positive so instead of
7--2 it would be 7+2
7+2=9
so the answer is 9

If the area of a rectangle is 64cm squared, how many different perimeters are possible when the dimensions are whole numbers
Answer:
2 different perimeters, 32 cm and 40 cm
Step-by-step explanation:
Given the area of a rectangle is 64 cm squared.
We know, Area of the rectangle is = length x breath
∴ 64 = 8 x 8
Hence the sides can be 8 cm by 8 cm.
So the perimeter of the rectangle is = 8 cm + 8 cm + 8 cm +8 cm
= 32 cm
Also, Area of the rectangle is = length x breath
∴ 64 = 16 x 4
So the perimeter of the rectangle is = 16 cm + 4 cm + 16 cm +4 cm
= 40 cm

System of equations that have the same slope have what kind of lines?
Answer:
parallel lines
Step-by-step explanation:
with an infinite number of solutions
Answer:
I think you are intended to answer parallel lines
Step-by-step explanation:
There are two answers to this.
1) The lines could be parallel if their y intercepts are different.
2) The lines are different forms of the same line.
For example
parallel:
y = 3x + 5y = 3x - 2Different forms of the same line.
y = 4x + 22y = 8x +4The second condition is termed consistent. The second condition is of 2 lines with the same slope and the same y intercept.

6x-5y-z=7 i have to eliminate x
the full question is
2x+y-3z=5
2x+3y+z=13
6x-5y-z=7
Answer: 2y - 20z = -16
Step-by-step explanation:
6(2x+y-3z) = 5(6)
=> 12x + 6y- 18z = 30
3(2x + 3y + z) = 13(3)
=> 6x + 9y + 3z = 39
Now minus the top equation from the bottom two:
12x + 6y - 18z = 30
6x + 9y + 3z = 39
6x - 5y - z = 7
12x + 6y - 18z = 30
12x + 4y + 2z = 46
Minus top from bottom:
2y - 20z = -16
