If x2 + y2 = 14 and xy = 5, find the value of (1/2 x + 1/2 y)2.
Answer:
(½x+½y)²=6
Step-by-step explanation:
x^2 + y^2 = 14, xy=5
(A+B)^2=A^2 +2AB+B^2... (*)
(1/2x+1/2y)^2 =(*)
(1/2x)^2 +2(1/2x)(1/2y)+(1/2y)^2 =
1/4x^2 +1/2xy+1/4y^2=
1/4(x^2 +y^2) +1/2(xy)=
1/4*14+1/2*5=
14/4+5/2=
14/4+10/4=
24/4=6
let me know if I'm wrong.
( 1/2x +1/2y)²
= { ( x + y )/ 2xy }²
= ( x² + 2xy + y² )/4(xy)² —(1)
As we know that x² + y² = 14 — (2)
and xy = 5 —(3)
So, substitute the value of equation 2 and 3 in equation 1,
= ( x² + 2xy + y²)/4(xy)²
=( 14 + 2*5)/(4*5²)
= 24/(4*25)
= 6/25.
Identify the slope and y-intercept of the line y = 9x - 3
Answer:
slope = 9 , y- intercept = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 9x - 3 ← is in slope- intercept form
with slope m = 9 and y- intercept c = - 3
If c-d=7 and c=3-8i what is d
Answer:
d=-4.......,...........
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
If,
c - d = 7
c = 3 - 8i
The value of d is -4 - 8i
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2x + 6 is an equation.
We have,
Two equations:
c - d = 7 _______(1)
c = 3 - 8i _______(2)
We are using the substitution method to solve this problem.
We make the value of a variable from an equation and substitute the value of that variable in the other equation.
From (1) we get,
c - d = 7
Add d on both sides.
c - d + d = 7 + d
c = 7 + d ______(3)
Put (3) on (2) we get,
7 + d = 3 - 8i
Subtract 7 on both sides.
7 + d - 7 = 3 - 8i - 7
d = -4 - 8i
Thus,
If,
c - d = 7
c = 3 - 8i
The value of d is -4 - 8i

Two cyclists start from 98 miles apart and begin racing toward each
other. Three hours later, they have not yet met and the distance between
them is 2 miles. How fast is each of them biking if one bikes 3 mph
slower than the other?
The speed of one bicyclist was 14.5mph, speed of the other bicyclist was 17.5mph.
Let the speed of one bicyclist=x mph
Let the speed of the other bicyclist=(x+3) mph
Hence:
Speed of one bicyclist:
3x+3(x+3)+2=98
3x+3x+9+2=98
6x=87
Divide both side by 6x
x=87/6
x=14.5 mph
Speed of the other bicyclist:
x+3 mph
14.5 mph+3 mph
=17.5 mph
Inconclusion the speed of one bicyclist was 14.5mph, speed of the other bicyclist was 17.5mph.

What is the slope of this line?
Enter your answer as a fraction, formatted like this: 42/53
Or, if the slope is undefined, enter a lowercase letter "u," like this: u
Answer:
-1/2
Step-by-step explanation:
To find the slope, you use the rise/run method.
To get from one point to another, you would move 1 unit down (rise) and 2 units to the right (left)
The slope would be -1/2
