Answer:

Step-by-step explanation:

1. Given that the local ice cream shop is deciding whether or not to hire a new worker. The shop must pay the worker hourly and cover a daily cost for insurance. The cost to pay an hourly worker for one day is represented by the function y=10x+30 where x=hours.

We find that this is of the form y = mx + B where

m = 10 and B = 30

Hence slope = m = 10

Answer is 10,

and it represents the rate of change of y for a unit change in x.

2. The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.

3. The answer is "Correlation, because time of day doesn't cause a person to run faster or slower ".

That's the correct answer because causation would mean there is a cause and effect and in the question, there is no cause. It can't be the last one because there is enough information. It also can't be the third one because there is a relationship since he shown he runs faster in the evening. Also I took the test and it was right!

24 POINTSSS for anyone who answers The of a square garden is 36x^2 -60+25 find the perimeter if x=3

Misha Larkins [42]

Answer:

The perimeter is 52

Step-by-step explanation:

The area is 36x^2 -60x+25

We set this equal to 0 to find the length and width

A= 36x^2 -60x+25

We notice that this is a perfect square trinomial

(a^2 -2ab-b^2) = (a-b)^2

let a = 6x and b=5

A=(6x-5) (6x-5)

The length and width are the same since is it a square (we know it is a square so they have to be equal)

The perimeter of a square is

P =4s

P =4 (6x-5)

Distribute the 4

= 24x -20

Let x =3

P = 24(3) -20

=72 -20

= 52

The perimeter is 52

(16x3 + 40x2 + 72) (2x + 6)

Volgvan

$(16x^3+40x^2+72)(2x+6)=32x^4+96x^3+80x^3+240x^2+144x+432=32x^4+176x^3+240x^2+144x+432$

In this case, you have to multiply each term of one parenthesis by each term in the second bracket. After receiving a number of factors need to be segregated and placed in the correct order.

Write the equation 2y - 4x = 5 in the form y = mx + b

KatRina [158]

2y - 4x = 5.....add 4x to both sides
2y = 4x + 5....divide both sides by 2
y = 2x + 5/2 <==

Solve for X. y=1/4 (x)+3

tia_tia [17]

The answer is:
____________________
x = 4y - 12 ; (Assuming the problem meant to solve for "x"; "in terms of "y").
_______________________
{Otherwise, the question might be "incomplete".}.
______________________________________________
The question seems incomplete; how can we solve for "x" when we do not know what "y" equals?
__________________________
However, it could be possible to "solve for x" in terms of "y". To so this, we need to isolate ""x" on one side of the equation:
_______________________________
Given: <span>y=1/4 (x) + 3 ; Let us multiply the ENTIRE EQUATION (both sides) by "4", to get rid of the "1/4" (fraction coefficent) of "x", and to "cancel out" the "1/4" fraction cofficient of "x" to the implied "1"; to help solve for "x" :
________________________________________
4 *{ </span>y= 1/4 (x) + 3} ;
______________________
4y = x + 12 ; Now we can subtract "12" from EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x":
_______________________
4y - 12 = x + 12 - 12 ;
________________________
4y - 12 = x ; This is our answer:
___________________________
x = 4y - 12 ; (Assuming the problem meant to solve for "x"; "in terms of "y").
