Solve the system of equations below for x, y, and z.
4x – 2y + 3z = 9
x - 2y=-3
2x + 3y=1
What is the solution (x, y, z)?
The solution to given system of equations are x = -1, y = 1 and z = 5 which is determined by the substitution method.
The given system of equations below as
4x – 2y + 3z = 9 ....(i)
x - 2y = -3 ....(ii)
2x + 3y = 1 ....(iii)
By equation (ii) and solving for x to get
x - 2y = -3
x = 2y - 3 ....(iv)
Substitute the value of x = 2y - 3 in the equation (iii)
2(2y - 3) + 3y = 1
4y - 6 + 3y = 1
7y = 7
y = 1
Substitute the value of y = 1 in equation (iv) to get,
x = 2(1) - 3
x = -1
Substitute the values of x = -1 and y = 1 in equation (i), and solve for z
4(-1) – 2(1) + 3z = 9
-4 - 2 + 3z = 9
3z = 15
z = 5
Therefore, the solution to given system of equation are x = -1, y = 1 and z = 5.

If the measure of angle 1 = - 9x + 6, and the measure of angle 2 = 2 (5x – 3), find x.
Answer:
x = 12
Step-by-step explanation:
The angle vertically opposite to ∠ 2 is corresponding to ∠ 1 and congruent, so
∠ 2 = ∠ 1 , substitute values
2(5x - 3) = 9x + 6 ← distribute parenthesis on left side
10x - 6 = 9x + 6 ( subtract 9x from both sides )
x - 6 = 6 ( add 6 to both sides )
x = 12
The length of a rectangle is 4 cm longer than the width the perimeter is no more than 28 cm what are the maximum possible dimensions for the rectangle
Answer:
Width <= 5 and length <= 9
Step-by-step explanation:
Width: x
Length: x+4
2x + 2(x+4) <= 28 (less or equal)
2x + 2x + 8 <= 28
4x <= 28-8
x <= 20/4
x <= 5
If length of a rectangle is 4 cm longer than the width the perimeter is no more than 28 cm. Then length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.
What is Area of Rectangle?The area of Rectangle is length times of width.
Let us consider width of rectangle be w= x cm
From given length of a rectangle is 4 cm longer than the width
l=(x+4)cm
The perimeter of rectangle =2(Length+width)
=2(x+x+4)
=2(2x+4)
=4x+8
the perimeter is no more than 28 cm
4x+8≤28
Subtract 8 on both sides
4x≤20
Divide both sides by 4
x≤5
Hence length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

What is the circumference of a circle with a radius of 40?
Answer:
C ≈ 251.33
Step-by-step explanation:
The circumference of a circle is C = 2πr
Radius = r = 40 is given in the problem
C = 2* 3.14 * 40
C ≈ 251.33
Answer:
251.2
Step-by-step explanation:
Given,
Radius ( r ) = 40
To find : Circumference of a circle = ?
Formula : -
Circumference of a circle = 2πr
Note : -
The value of π is :
22 / 7 ( in fraction ).3.14 ( in decimal ).Solution : -
Circumference of a circle = 2πr
= 2 x 3.14 x 40
Circumference of a circle = 251.2
Therefore,
Circumference of a circle is 251.2

A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Which statement about the quadrilateral is true?
Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:
You can see that vectors and This means that opposite sides are parallel and option B is false.
Find the lengths of all sides:
As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.
Now check whether angles A and B are perpendicular:
The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides

For Incap T-shirts, the cost of producing x T-shirts can be expressed as C=0.6x2+0.52x+3200.
The revenue they gain can be expressed as R=100x.
At what value of x is the profit (R−C) maximised?
In other words, what is the ideal number of T-shirts to make and sell?
The value of x in which profit can be maximized is -43.67
Given:
C = 0.6x² + 0.52x + 3200
R = 100x
The profit maximizing value of x = R - C
= 100x - (0.6x² + 0.52x + 3200)
= 100x - 0.6x² - 0.52x - 3200
= 0.6x² + 99.48x - 3200
x = -b ± √b² - 4ac / 2a
= 99.48 ± √99.48² - 4×0.6×-3200
= -99.48 ± √9,896.2704 - 7680 / 1.2
= -99.48 ± √2,216.2704 / 1.2
= -99.48 ± 47.08 / 1.2
x = -99.48 + 47.08 / 1.2
or = -99.48 - 47.08 / 1.2
x = -52.4/1.2 or -146.56 / 1.2
x = -43.67 or -122.13
Therefore, the value of x is -43.67
