Multiply each side of the statement by (-3) < 4 by (-1). Is the inequality symbol preserved or reversed?
Answer:
Reversed
Step-by-step explanation:
If you multiply each side by -1, then the equation becomes;
3 < (-4)
which is incorrect. The symbol would have to be the other way which means that the inequality symbol is going to be reversed.
Answer:
Reversed

Emily, Zeke, Harry, and Brook each conducted surveys on the number of books people have in their homes. Then, each student determined the accuracy of the following statement.
All measures of central tendency must appear as a number in the set of data collected.
Which student’s statement is CORRECT?
A.
Zeke says this is never true because all the measures of central tendency are never numbers in the set of data.
B.
Emily says this is always true because all the measures of central tendency also have to be numbers in the set of data.
C.
Harry says this is sometimes true because the mean and median may or may not be in the set of data, but the mode is always in the set of data.
D.
Brook says this is sometimes true because the mean and mode may or may not be in the set of data, but the median is always in the set of data.

A flat-screen television costs $724.89 when it is new. The value of the television is expected to change by −12 3/5% per year. What is the expected value, to the nearest cent, of the television after 4 years?
The solution is $ 422.98
The expected value of the television after 4 years is $ 422.98
What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the initial amount of the television be x₀
The value of x₀ = $ 724.89
Now , value of the television is expected to change by -12 3/5 % per year
So , the exponential decay rate of the television is r = -12 3/5 %
The rate r = -63/5 %
The rate r = -12.6 %
The number of years t = 4 years
So , the exponential decay rate of the television after 4 years is calculated from the formula
x ( t ) = x₀ × ( 1 + r )ⁿ
Substituting the values in the equation , we get
x ( 4 ) = 724.89 ( 1 - ( 12.6/100 ) )⁴
On simplifying the equation , we get
x ( 4 ) = 724.89 ( 1 - 0.126 )⁴
x ( 4 ) = 724.89 ( 0.874 )⁴
x ( 4 ) = 724.89 x 0.583506543376
x ( 4 ) = $ 422.978
So , rounding to the nearest cent , we get
The value of x ( 4 ) = $ 422.98
Hence , The expected value of the television after 4 years is $ 422.98

Help 7TH GRADE math I give out good rating and BRAINIEST!
Answer:
12.6
Step-by-step explanation:
If 21 divided by 5 is 4.2, you should multiply 3 by 4.2 you'll then get 12.6. to double check, do 5 divided by 3, which is 1.67, and 21 divided by 12.6 is also 1.67. so side OP is 12.6! :)

dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year. how much will he earn in 4 years?
Answer:
= $655.20
Step-by-step explanation:
Simple Interest =( Principal * rate * time)/100
=( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.
= 65520/100
= $655.20
Dexter will earn $655.2.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
Formula to calculate the simple interest is;
S.I. = P x T x R / 100 ,
Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.
Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.
P = $6300
R = 2.60% and T = 4 years
Then by the formula;
6300 x 2.6 x 4 /100
= $655.2
Therefore, Dexter will earn $655.2.

Solve the system y = -x + 7 and y = -0.5(x - 3)^2 + 8
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
-x+7=-0.5x^10 -4.5^10
am I getting ...!?
Answer:
(-1,6) and (-7,0)
Step-by-step explanation:
-x+7=-0.5(x-3)^2+8
times both sides by -2
2x-14=(x-3)^2-16
expand
2x-14=x^2-6x+9-16
add 14-2x to both sides
0=x^2-8x+7
factor
0=(x-7)(x-1)
set to zero
0=x-7
7=x
0=x-1
1=x
so find y
y=-x+7
y=-1+7
y=6
or
y=-7+7
y=0

Answer:
The bicyclist rides (64) miles in (4) hours.
Step-by-step explanation:
As you can see the 64 is on the Distance side, so that shows how far he or she travels. Then you can see on the bottom of the graph it shows you time in hours. The point is at 4, so he or she travels 64 miles in 4 hours.

Answer:
25. y=2x+1
26. $13
Step-by-step explanation:
25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.
26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.
good luck, and have a great day. :)
