Answer:
y = 0
Step-by-step explanation:
-2y-4=4(y-1)
First you want to distribute it
-2y - 4 = 4y - 4
Then just subtract -4y from both sides to neutralize 4y
-6y -4 = -4
then you have to add 4 to neutralize -4
-6y= 0
thus the answer is y= 0

The arch of a bridge forms a parabola with the function \displaystyle f(x)=-0.05(x-30)^{2}+45f(x)=−0.05(x−30) 2 +45 where x is the horizontal distance (in meters) from the arch's left end and y is the height (in meters) above the road. How many meters high is the arch at its highest point?
Answers
Answer:
40mStep-by-step explanation:
If the arch of a bridge forms a parabola with the function
f(x)=−0.05(x−30)² +45 where x is the horizontal distance;
The arc is at its highest point at when df(x)/dx = 0
df(x)/dx = -2(0.05)(x-30)(1) + 0
df(x)/dx = -0.1(x-30)
df(x)/dx = -0.1x+3
Since df(x)/dx = 0
-0.1x+3 = 0
-0.1x = -3
x = -3/-0.1
x = 20
Substitute x = 20 into the function as shown:
f(x)=−0.05(x−30)² +45
f(20)=−0.05(20−30)² +45
f(20)=−0.05(-10)² +45
f(20)=−0.05(100) +45
f(20)=-5+45
f(20) = 40
Hence the arch is 40meters high at its highest point

A shop sells bagels for $5 per dozen. You can use the table to answer
the questions. Explain your reasoning. (Show all your work)
1. At this rate, how much would 6 bagels cost?
2. How many bagels can you buy for $50?
Answers
Answer with step-by-step explanation:
Lets says the number of bagels is B and the price in dollars is D.
Equation: D × 12/5 = B
1. 6 is half of a dozen, which means the price would be half of 5, 2.5
2. $50 is 10× the amount of $5, so the amount of bagels would be 10 × 12, which is 120 bagels.
Hope this helped! (brainliest please)
A Dozen mathematically means 12.
It is important to note that:
$5 = 12 bagels
1) 12 bagels = $56 bagels = ?
Cross Multiply
6 bagels x $5 / 12
= $7.50
Therefore, 6 bagels would cost $7.50
2) $5 = 12 bagels$50 = ?
Cross multiply
$50 x 12 bagels / $5
= 120 bagels
Therfore, you can buy 120 bagels for $50

A sales person in a stereo store is given a choice of two different compensation plans. One plan offers a weekly salary of $250 plus a commission of $25 for each stereo sold. The other plan offers no salary but pays $50 commission on each stereo sold. How many stereos must the sales person sell to make the same amount of money under both plans ?
Answers
Answer:
The salesperson needs to sell 10 stereos to make the same money on both plans
Step-by-step explanation:
We'll analyze both choices for the compensation plans of a salesperson.
One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:
P1=250+25x
Where x is the number of stereos sold.
The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:
P2=50x
To find the equilibrium point for both plans, we make P1=P2:
250+25x=50x
Simplifying:
25x=250
Solving:
x = 250 / 25 = 10
The salesperson needs to sell 10 stereos to make the same money on both plans

Answers
Answer: The population is 730 and the sample is 102.
Step-by-step explanation:
When we have a given set of elements, N elements, the population is N.
And if we do statistics with A of these N elements, the sample is A.
In this case, the population is the set of the 730 drivers, then the population is 730.
And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).
Then the sample will be 102.
Then the correct option is:
The population is 730 and the sample is 102.
