b). Kirchoff has more money than Maxi. If Kirchoff gave Maxi $20, they would have the
same amount. While it Maxi gave Kirchoff $22, Kirchoff would then have twice as much as
Maxi. How much does each one actually have?
Answers
Answer:
k = 146
m= 106
Kirchoff has $146
Maxi has $106
Step-by-step explanation:
For the purpose of the equations, I’ll call Kirchoff and Maxi a and b respectively.
a - 20 = b + 20 (equation 1)
2(b - 22) = a + 22 (equation 2)
We can juggle those around for
a = b +40 (equation 1r (re-arranged)) and
2b - 44 = a + 22 so 2b - 66 = a (equation 2r (rearranged))
The equations are now:
a = b + 40 (new equation 1) and
a = 2b - 66 (new equation 2)
Substitute from new equation 1 to new equation 2:
b + 40 = 2b - 66 so 40 = b - 66 making b = 106.
Plug b = 106 into new equations 1 and 2 for:
a = 106 + 40 (new equation 1) and
a = 212 - 66 (new equation 2)
This gives a = 146 and b = 106
TEST: There’s a gap of $40, so giving $20 from a to b makes them equal.
SECOND TEST: Subtracting $22 from b makes it $84 and giving that sum to a makes it $168, twice as much. The tests work.
Kirchoff has $146 and Maxi has $106.
Select the correct answer. Which equation represents the vertical line passing through (1,-9)? A x=-9 B. X= 1 C. y=-9 D y=1 Reset
Answers
Answer:
x = 1
Step-by-step explanation:
the vertical line is passing through only the x-axis and not the y axis. So the graph is a x = ? All you e have to to is to look for the x coordinate of the point the vertical line is passing through which is 1 and so the answer is x = 1.
Please mark brainliest. Thanks!!!!
x=1 represents the vertical line passing through (1,-9) .
What is vertical line ?A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane.
In a vertical line x-coordinate remain constant, only y-coordinate changes.
The vertical lines are parallel to the y-axis and are perpendicular to the horizontal lines. On a vertical line, all the points on the line have the same x-coordinate.
Here x=1 is the only vertical line which passes through (1,-9) So option B is correct.

What is the value of a?
Answers
Answer:
a = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
a + 8 + 2a + 43 = 180
3a + 51 = 180 ( subtract 51 from both sides )
3a = 129 ( divide both sides by 3 )
a = 43

Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial
Answers
Answer:
Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]
Degree of polynomial = 3
Step-by-step explanation:
The given polynomials are:
[tex]x(3x-1)(2x+5)[/tex]
In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.
So, multiplying the polynomials in round brackets first
[tex]=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)[/tex]
Now multiplying with x
[tex]= 6x^3+13x^2-5x[/tex]
Degree of a polynomial is the highest exponent of variable in the polynomial.
In the acquired result, the highest exponent of x is 3 so the degree is 3.
Hence,
Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]
Degree of polynomial = 3

In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. In other words, to be coplanar, all points have to lie in the same plane. Point d is not in the plane, therefore all points except d, are non coplanar.

− 3/4 is not an integer but a a rational number.
Why is this correct?A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.
On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.
