(1,-2)(5,4) find the mid point
Answer:
Step-by-step explanation:
Given points A ( 1 , - 2) and B ( 5 , 4)
Mid point of AB is
= ( ( x1 +x2)/ 2 , ( y1+ y2)/ 2 )
= ( ( 1 + 5)/2 , ( - 2 + 4)/2 )
= ( 3 , 1 )

if xsqured +y squred =16, xy=10 find the value of x+y using bionomial expansion
Answer:
x+y=6Step-by-step explanation:
to understand thisyou need to know about:algebraPEMDAStips and formulas:x²+y²=(x+y)²-2xylet's solve:according to the question:
(x+y)²-2xy=16substitute the value of xy:(x+y)²-2.10=16simplify multiplication:(x+y)²-20=16add 20 to both sides:(x+y)²-20+20=16+20=>(x+y)²=36[tex] \sf squre \: root \: both \: sides : \\ \sqrt{ (x + y {)}^{2}} = \sqrt{36} \\ \therefore x + y = 6[/tex]9 times a number is the sum of the number and 56.

11/6=n+7/9 what does n equal
Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
-n + 11/6 = 7/9
-n = 7/9 - 11/6
-n = -19/18
n = 19/18
Answer:
n = 19/18
Step-by-step explanation:
The equation 11/6=n+7/9 has fractions with two different denominators (6 and 9). The LCD is 18, which is the smallest number evenly divisible by 6 and 9. Thus, we can rewrite 11/6=n+7/9 as:
33/18 = (18/18)n + 14/18 (Now all three denominators are the same: 18)
Then 33 = 18n + 14, or
19 = 18n
Dividing both sides by 18, we get n = 19/18
Check: Is 11/6 = 19/18 + 7/9 true? YES

5.Regarding the equations below. What is the value of x?
5x + 2y = 4
x – 3y = –23
Answer:
x=−2
y=7
Step-by-step explanation:
5x+2y=4
x−3y=−23
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
5x+2y=4,x−3y=−23
To make 5x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 5.
5x+2y=4,5x+5(−3)y=5(−23)
Simplify.
5x+2y=4,5x−15y=−115
Subtract 5x−15y=−115 from 5x+2y=4 by subtracting like terms on each side of the equal sign.
5x−5x+2y+15y=4+115
Add 5x to −5x. Terms 5x and −5x cancel out, leaving an equation with only one variable that can be solved.
2y+15y=4+115
Add 2y to 15y.
17y=4+115
Add 4 to 115.
17y=119
Divide both sides by 17.
y=7
Substitute 7 for y in x−3y=−23. Because the resulting equation contains only one variable, you can solve for x directly.
x−3×7=−23
Multiply −3 times 7.
x−21=−23
Add 21 to both sides of the equation.
x=−2
The system is now solved.
x=−2,y=7

Find angles A, B, C, D, & E.
Answer:
Step-by-step explanation:
B = 35 {Alternate interior angles}
C = 75 {Corresponding angles}
D + 75 = 180 {Linear pair}
D = 180 - 75
D = 105
A = C {Corresponding angles}
A = 75
E = A {Alternate interior angles}
E = 75

Determine the coordinates of the y-intercept of 3x − 4y = 24.
Answer:
(0, -6)
Step-by-step explanation:
At the y-intercept, the x-coordinate equals zero.
3x - 4y = 24
3(0) - 4y = 24
-4y = 24
y = -6
Answer: (0, -6)

Addison earns a fixed hourly rate working as a sales clerk. If she works on a holiday, she earns a different hourly rate than she earns on a regular day. In one week, she earns $188.50 by working 5 hours on a holiday and 16 hours during regular days. A different week, she earns $254.00 by working 8 hours on a holiday and 20 hours during regular days.
Answer:
10.50
Step-by-step explanation:
A salesperson works 40 hours per week at a job where has two options for being paid. Option A is an hourly wage of $20. Option B is a commission rate of 10% on weekly sales. How much does need to sell this week to earn the same amount with the two options?
Please help..
Answer:
$8,000
Step-by-step explanation:
40x20= .1s
8000=s
First option, the salesperson will earn 40*20=800 dollars.
For second option, the person will earn the amount he sells/10.
For them to be equal the second salesperson have to sell 800*10=8000 dollars of items to earn that as much money as the first salesperson.
