Answer:
7. M = (-1.5,7)
8. (8,4)
9. m<QRS=46°
Step-by-step explanation:
7. Use the midpoint formula which is (x1+x2/2 , y1+y2/2)
So (-1-2/2 , 9+5/2)
(-3/2 , 14/2)
So M = (-1.5,7)
8. This is one simple if you understand.
Since (-6,6) is the starting end point and (1,5) is the mid point then (8,4) has to be the other end point. -6 to 1 is +7. 1 to 8 is +7. 6 to 5 is -1. 5 to 4 is -1.
9. 3x-8+2x+6=98
5x-2=98
5x=100
x=20
So plug in x for QRS
2(20)+6
40+6
46

13. You are debating about whether to buy a new computer for $800.00 or refurbished computer with the same equipment for $640.00. If you are paid
$10.00/hour and your deductions
are FICA (7.65%), federal tax withholding (12%), and state tax withholding (8%), how many hours do you have to work to pay for the new computer?
89 hours
•
98 hours
•
87 hours
•
111 hours
The number of hours to work to pay for the new computer is 111 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
The cost difference between the new and refurbished computer is $800.00 - $640.00 = $160.00. This means that you would save $160.00 by buying the refurbished computer instead of the new one.
Let's say you work for "x" hours, then your gross pay will be:
A = 10x dollars
Your FICA deduction will be 7.65% of your gross pay:
0.0765 ( 10x ) = 0.765x dollars
Your federal tax withholding will be 12% of your gross pay:
0.12 ( 10x ) = 1.2x dollars
Your state tax withholding will be 8% of your gross pay:
0.08 ( 10x ) = 0.8x dollars
The total amount of taxes that will be deducted from your paycheck is the sum of these three amounts:
0.765x + 1.2x + 0.8x = 2.765x dollars
So your net pay will be:
10x - 2.765x = 7.235x dollars
On simplifying the equation , we get
Now, we can calculate the number of hours you would need to work to pay for the new computer:
800 = 7.235x
x ≈ 110.5 hours
Hence , the number of hours is x = 111 hours

2y + 8y - 20 = 5 (y -2) simplify
Answer:
y=2
Step-by-step explanation:
2y + 8y - 20 = 5 (y -2)
Combine like terms
10y -20 = 5(y-2)
Divide by 5
10y/5 -20/5 = 5/5(y-2)
2y -4 = y-2
Subtract y from each side
2y-y -4 =-2
y -4 = -2
Add 2 to each side
y-4+4 =-2+4
y =2
Answer:
[tex]2y + 8y - 20 = 5(y - 2) \\ 10y - 20 = 5y - 10 \\ 5y = 10 \\ y = 2 \\ thank \: you[/tex]

Compare: (i) −2/ 5 and −1 /5 (ii) −5/ 7 and −3 /7 (iii) 2 /9 and −5 /11
Answer:
(i) −2/ 5 < −1 /5 since -2 < -1 and denominators are same(ii) −5/ 7 < −3 /7 since -5 < -3 and denominators are same(iii) 2 /9 > −5 /11 as comparing negative and positive numbersStep-by-step explanation:
-2/5 and -1/5
Since -1 > -2
So, -2/5 < -1/5
(ii) -5/7 and -3/7
Since -5 < -3
So, -5/7 < -3/7
(iii)
2/9 and -5/11
Note :- That all positive fraction are greater than negative fraction.
So, 2/9 > -5/11

So
Displacement = velocity x time
Velocity = - 8 feet/s ( negative bcuz going down)
Time = 13
Displacement = - 8 x 13
= - 104
Therefore

0 If 3x+ 11 = 86-5 the x = ?
Answer: x = 70/3
Step-by-step explanation:
Given equation
3x + 11 = 86 - 5
Simplify by subtraction
3x + 11 = 81
Subtract 11 on both sides
3x + 11 - 11 = 81 - 11
3x = 70
Divide 3 on both sides
3x / 3 = 70 / 3
