What is the equation of a line through the points (0,9) and (3,0)?

The complete question is

"Which values of x and y would make the following expression represent a real number? (4 + 5i)(x + yi)"

The value of x and y are all points that satisfy the equation would be,(4,-5).

Use the distributive property to simplify the expression.

The given expression is,

(4 + 5i)(x + yi)

4(x + yi)+ 5i (x + yi)

4x + 4yi + 5xi + 5yi^2

We know that i^2 = -1

4x + 4yi + 5xi - 5y

(4x - 5y) +i (  4y + 5x)

In x+iy, x is the real part and y is the imaginary part.

If the given expression represents a real number it means the imaginary part must be zero.

4y + 5x= 0

All the points which satisfy the above equation are the values of x and y for which the given expression is a real number.

For eg. (4,-5)

4y + 5x

4(-5) + 5(4)

= 0

LHS=RHS, which means the point satisfies the equation and the value of x and y are (4,-5).

Students can work no more than 23 hours per week

⇒ Let the hours per week be x

⇒ 'no more than' refers to less than or equal to (≤)

⇒ x ≤ 23

Answer:

X= 1/2 Y= 5

Step-by-step explanation:

8x+7y=39-------------(1)--------×2

4x-14y= -68-----------(2)-------×1

16X + 14Y = 78--------(3)

4X- 14Y = -68----------(4)

Addy equation (4) and (3)

20X = 10

dividing bothsides by 20

20X/20= 10/20

X = 1/2

substitute the value of X into equation (1)

8X+7Y = 39

8(1/2)+7Y= 39

4+7Y = 39

7Y = 39-4

7Y = 35
